Query fields after query multiple tables on multiple databases - sql

I am trying to do a interesting query. I have a lot of databases and they have a table with the same name (e.g : mytable). I want to find something in this table but searching all this table occurrence on the server.
I tried:
sp_msforeachdb 'Select * from Sysobjects where name=''mytable'''
This lists all the 'mytable' tables on the server.
I also used
select * from [table].[dbo].[mytable] where myclause
I tried to join these two queries, but I am was not able to find the correct way to do that (if there is a way).
I tried case, join, inner join but it is really hard to get what I want.

Try this:
sp_msforeachdb 'insert into MyMasterDB.dbo.ResultsTable select * from [?].dbo.[MyTable] where myclause'
OR (with db name in results)
DECLARE #SQL AS VARCHAR(MAX)
select #SQL = 'insert into MyMasterDB.dbo.ResultsTable select ? as DB_Name, col1, cast (col2 as varchar (50)), col3 from [?].dbo.[MyTable] where myclause'
sp_msforeachdb #SQL
To escape ' (single quote) use '' (two double quotes)

SQL joining huge tables by excluding just one column in select statement [duplicate]

I'm trying to use a select statement to get all of the columns from a certain MySQL table except one. Is there a simple way to do this?
EDIT: There are 53 columns in this table (NOT MY DESIGN)
Actually there is a way, you need to have permissions of course for doing this ...
SET #sql = CONCAT('SELECT ', (SELECT REPLACE(GROUP_CONCAT(COLUMN_NAME), '<columns_to_omit>,', '') FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = '<table>' AND TABLE_SCHEMA = '<database>'), ' FROM <table>');
PREPARE stmt1 FROM #sql;
EXECUTE stmt1;
Replacing <table>, <database> and <columns_to_omit>
(Do not try this on a big table, the result might be... surprising !)
TEMPORARY TABLE
DROP TABLE IF EXISTS temp_tb;
CREATE TEMPORARY TABLE ENGINE=MEMORY temp_tb SELECT * FROM orig_tb;
ALTER TABLE temp_tb DROP col_a, DROP col_f,DROP col_z; #// MySQL
SELECT * FROM temp_tb;
DROP syntax may vary for databases #Denis Rozhnev
Would a View work better in this case?
CREATE VIEW vwTable
as
SELECT
col1
, col2
, col3
, col..
, col53
FROM table
You can do:
SELECT column1, column2, column4 FROM table WHERE whatever
without getting column3, though perhaps you were looking for a more general solution?
If you are looking to exclude the value of a field, e.g. for security concerns / sensitive info, you can retrieve that column as null.
e.g.
SELECT *, NULL AS salary FROM users
To the best of my knowledge, there isn't. You can do something like:
SELECT col1, col2, col3, col4 FROM tbl
and manually choose the columns you want. However, if you want a lot of columns, then you might just want to do a:
SELECT * FROM tbl
and just ignore what you don't want.
In your particular case, I would suggest:
SELECT * FROM tbl
unless you only want a few columns. If you only want four columns, then:
SELECT col3, col6, col45, col 52 FROM tbl
would be fine, but if you want 50 columns, then any code that makes the query would become (too?) difficult to read.
While trying the solutions by #Mahomedalid and #Junaid I found a problem. So thought of sharing it. If the column name is having spaces or hyphens like check-in then the query will fail. The simple workaround is to use backtick around column names. The modified query is below
SET #SQL = CONCAT('SELECT ', (SELECT GROUP_CONCAT(CONCAT("`", COLUMN_NAME, "`")) FROM
INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'users' AND COLUMN_NAME NOT IN ('id')), ' FROM users');
PREPARE stmt1 FROM #SQL;
EXECUTE stmt1;
If the column that you didn't want to select had a massive amount of data in it, and you didn't want to include it due to speed issues and you select the other columns often, I would suggest that you create a new table with the one field that you don't usually select with a key to the original table and remove the field from the original table. Join the tables when that extra field is actually required.
You could use DESCRIBE my_table and use the results of that to generate the SELECT statement dynamically.
My main problem is the many columns I get when joining tables. While this is not the answer to your question (how to select all but certain columns from one table), I think it is worth mentioning that you can specify table. to get all columns from a particular table, instead of just specifying .
Here is an example of how this could be very useful:
select users.*, phone.meta_value as phone, zipcode.meta_value as zipcode
from users
left join user_meta as phone
on ( (users.user_id = phone.user_id) AND (phone.meta_key = 'phone') )
left join user_meta as zipcode
on ( (users.user_id = zipcode.user_id) AND (zipcode.meta_key = 'zipcode') )
The result is all the columns from the users table, and two additional columns which were joined from the meta table.
I liked the answer from #Mahomedalid besides this fact informed in comment from #Bill Karwin. The possible problem raised by #Jan Koritak is true I faced that but I have found a trick for that and just want to share it here for anyone facing the issue.
we can replace the REPLACE function with where clause in the sub-query of Prepared statement like this:
Using my table and column name
SET #SQL = CONCAT('SELECT ', (SELECT GROUP_CONCAT(COLUMN_NAME) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'users' AND COLUMN_NAME NOT IN ('id')), ' FROM users');
PREPARE stmt1 FROM #SQL;
EXECUTE stmt1;
So, this is going to exclude only the field id but not company_id
Yes, though it can be high I/O depending on the table here is a workaround I found for it.
SELECT *
INTO #temp
FROM table
ALTER TABLE #temp DROP COlUMN column_name
SELECT *
FROM #temp
It is good practice to specify the columns that you are querying even if you query all the columns.
So I would suggest you write the name of each column in the statement (excluding the one you don't want).
SELECT
col1
, col2
, col3
, col..
, col53
FROM table
I agree with the "simple" solution of listing all the columns, but this can be burdensome, and typos can cause lots of wasted time. I use a function "getTableColumns" to retrieve the names of my columns suitable for pasting into a query. Then all I need to do is to delete those I don't want.
CREATE FUNCTION `getTableColumns`(tablename varchar(100))
RETURNS varchar(5000) CHARSET latin1
BEGIN
DECLARE done INT DEFAULT 0;
DECLARE res VARCHAR(5000) DEFAULT "";
DECLARE col VARCHAR(200);
DECLARE cur1 CURSOR FOR
select COLUMN_NAME from information_schema.columns
where TABLE_NAME=#table AND TABLE_SCHEMA="yourdatabase" ORDER BY ORDINAL_POSITION;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
OPEN cur1;
REPEAT
FETCH cur1 INTO col;
IF NOT done THEN
set res = CONCAT(res,IF(LENGTH(res)>0,",",""),col);
END IF;
UNTIL done END REPEAT;
CLOSE cur1;
RETURN res;
Your result returns a comma delimited string, for example...
col1,col2,col3,col4,...col53
I agree that it isn't sufficient to Select *, if that one you don't need, as mentioned elsewhere, is a BLOB, you don't want to have that overhead creep in.
I would create a view with the required data, then you can Select * in comfort --if the database software supports them. Else, put the huge data in another table.
At first I thought you could use regular expressions, but as I've been reading the MYSQL docs it seems you can't. If I were you I would use another language (such as PHP) to generate a list of columns you want to get, store it as a string and then use that to generate the SQL.
Based on #Mahomedalid answer, I have done some improvements to support "select all columns except some in mysql"
SET #database = 'database_name';
SET #tablename = 'table_name';
SET #cols2delete = 'col1,col2,col3';
SET #sql = CONCAT(
'SELECT ',
(
SELECT GROUP_CONCAT( IF(FIND_IN_SET(COLUMN_NAME, #cols2delete), NULL, COLUMN_NAME ) )
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = #tablename AND TABLE_SCHEMA = #database
),
' FROM ',
#tablename);
SELECT #sql;
If you do have a lots of cols, use this sql to change group_concat_max_len
SET ##group_concat_max_len = 2048;
I agree with #Mahomedalid's answer, but I didn't want to do something like a prepared statement and I didn't want to type all the fields, so what I had was a silly solution.
Go to the table in phpmyadmin->sql->select, it dumps the query: copy, replace and done! :)
While I agree with Thomas' answer (+1 ;)), I'd like to add the caveat that I'll assume the column that you don't want contains hardly any data. If it contains enormous amounts of text, xml or binary blobs, then take the time to select each column individually. Your performance will suffer otherwise. Cheers!
Just do
SELECT * FROM table WHERE whatever
Then drop the column in you favourite programming language: php
while (($data = mysql_fetch_array($result, MYSQL_ASSOC)) !== FALSE) {
unset($data["id"]);
foreach ($data as $k => $v) {
echo"$v,";
}
}
The answer posted by Mahomedalid has a small problem:
Inside replace function code was replacing "<columns_to_delete>," by "", this replacement has a problem if the field to replace is the last one in the concat string due to the last one doesn't have the char comma "," and is not removed from the string.
My proposal:
SET #sql = CONCAT('SELECT ', (SELECT REPLACE(GROUP_CONCAT(COLUMN_NAME),
'<columns_to_delete>', '\'FIELD_REMOVED\'')
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = '<table>'
AND TABLE_SCHEMA = '<database>'), ' FROM <table>');
Replacing <table>, <database> and `
The column removed is replaced by the string "FIELD_REMOVED" in my case this works because I was trying to safe memory. (The field I was removing is a BLOB of around 1MB)
You can use SQL to generate SQL if you like and evaluate the SQL it produces. This is a general solution as it extracts the column names from the information schema. Here is an example from the Unix command line.
Substituting
MYSQL with your mysql command
TABLE with the table name
EXCLUDEDFIELD with excluded field name
echo $(echo 'select concat("select ", group_concat(column_name) , " from TABLE") from information_schema.columns where table_name="TABLE" and column_name != "EXCLUDEDFIELD" group by "t"' | MYSQL | tail -n 1) | MYSQL
You will really only need to extract the column names in this way only once to construct the column list excluded that column, and then just use the query you have constructed.
So something like:
column_list=$(echo 'select group_concat(column_name) from information_schema.columns where table_name="TABLE" and column_name != "EXCLUDEDFIELD" group by "t"' | MYSQL | tail -n 1)
Now you can reuse the $column_list string in queries you construct.
I wanted this too so I created a function instead.
public function getColsExcept($table,$remove){
$res =mysql_query("SHOW COLUMNS FROM $table");
while($arr = mysql_fetch_assoc($res)){
$cols[] = $arr['Field'];
}
if(is_array($remove)){
$newCols = array_diff($cols,$remove);
return "`".implode("`,`",$newCols)."`";
}else{
$length = count($cols);
for($i=0;$i<$length;$i++){
if($cols[$i] == $remove)
unset($cols[$i]);
}
return "`".implode("`,`",$cols)."`";
}
}
So how it works is that you enter the table, then a column you don't want or as in an array: array("id","name","whatevercolumn")
So in select you could use it like this:
mysql_query("SELECT ".$db->getColsExcept('table',array('id','bigtextcolumn'))." FROM table");
or
mysql_query("SELECT ".$db->getColsExcept('table','bigtextcolumn')." FROM table");
May be I have a solution to Jan Koritak's pointed out discrepancy
SELECT CONCAT('SELECT ',
( SELECT GROUP_CONCAT(t.col)
FROM
(
SELECT CASE
WHEN COLUMN_NAME = 'eid' THEN NULL
ELSE COLUMN_NAME
END AS col
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'employee' AND TABLE_SCHEMA = 'test'
) t
WHERE t.col IS NOT NULL) ,
' FROM employee' );
Table :
SELECT table_name,column_name
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'employee' AND TABLE_SCHEMA = 'test'
================================
table_name column_name
employee eid
employee name_eid
employee sal
================================
Query Result:
'SELECT name_eid,sal FROM employee'
I use this work around although it may be "Off topic" - using mysql workbench and the query builder -
Open the columns view
Shift select all the columns you want in your query (in your case all but one which is what i do)
Right click and select send to SQL Editor-> name short.
Now you have the list and you can then copy paste the query to where ever.
If it's always the same one column, then you can create a view that doesn't have it in it.
Otherwise, no I don't think so.
I would like to add another point of view in order to solve this problem, specially if you have a small number of columns to remove.
You could use a DB tool like MySQL Workbench in order to generate the select statement for you, so you just have to manually remove those columns for the generated statement and copy it to your SQL script.
In MySQL Workbench the way to generate it is:
Right click on the table -> send to Sql Editor -> Select All Statement.
The accepted answer has several shortcomings.
It fails where the table or column names requires backticks
It fails if the column you want to omit is last in the list
It requires listing the table name twice (once for the select and another for the query text) which is redundant and unnecessary
It can potentially return column names in the wrong order
All of these issues can be overcome by simply including backticks in the SEPARATOR for your GROUP_CONCAT and using a WHERE condition instead of REPLACE(). For my purposes (and I imagine many others') I wanted the column names returned in the same order that they appear in the table itself. To achieve this, here we use an explicit ORDER BY clause inside of the GROUP_CONCAT() function:
SELECT CONCAT(
'SELECT `',
GROUP_CONCAT(COLUMN_NAME ORDER BY `ORDINAL_POSITION` SEPARATOR '`,`'),
'` FROM `',
`TABLE_SCHEMA`,
'`.`',
TABLE_NAME,
'`;'
)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE `TABLE_SCHEMA` = 'my_database'
AND `TABLE_NAME` = 'my_table'
AND `COLUMN_NAME` != 'column_to_omit';
I have a suggestion but not a solution.
If some of your columns have a larger data sets then you should try with following
SELECT *, LEFT(col1, 0) AS col1, LEFT(col2, 0) as col2 FROM table
If you use MySQL Workbench you can right-click your table and click Send to sql editor and then Select All Statement This will create an statement where all fields are listed, like this:
SELECT `purchase_history`.`id`,
`purchase_history`.`user_id`,
`purchase_history`.`deleted_at`
FROM `fs_normal_run_2`.`purchase_history`;
SELECT * FROM fs_normal_run_2.purchase_history;
Now you can just remove those that you dont want.

How to select all the columns of a table except one column?

How to select all the columns of a table except one column?
I have nearly 259 columns I cant mention 258 columns in SELECT statement.
Is there any other way to do it?
You can use this approach to get the data from all the columns except one:-
Insert all the data into a temporary table
Then drop the column which you dont want from the temporary table
Fetch the data from the temporary table(This will not contain the data of the removed column)
Drop the temporary table
Something like this:
SELECT * INTO #TemporaryTable FROM YourTableName
ALTER TABLE #TemporaryTable DROP COLUMN Columnwhichyouwanttoremove
SELECT * FROM #TemporaryTable
DROP TABLE #TemporaryTable
Create a view. Yes, in the view creation statement, you will have to list each...and...every...field...by...name.
Once.
Then just select * from viewname after that.
This is not a generic solution, but some databases allow you to use regular expressions to specify the columns.
For instance, in the case of Hive, the following query selects all columns except ds and hr:
SELECT `(ds|hr)?+.+` FROM sales
You can get the column name details from sys.columns table
Try the following query:
SELECT * FROM SYS.COLUMNS
WHERE object_id = OBJECT_ID('dbo.TableName')
AND [Name] <> 'ColumnName'
DECLARE #sql as VARCHAR(8000)
SET #sql = 'SELECT '
SELECT #sql += [Name] + ', ' FROM SYS.COLUMNS
WHERE object_id = OBJECT_ID('dbo.TableName')
AND [Name] <> 'ColumnName'
SELECT #sql += ' FROM Dbo.TableName'
EXEC(#sql)
I just wanted to echo #Luann's comment as I use this approach always.
Just right click on the table > Script table as > Select to > New Query window.
You will see the select query. Just take out the column you want to exclude and you have your preferred select query.
There are lot of options available , one of them is :
CREATE TEMPORARY TABLE temp_tb SELECT * FROM orig_tb;
ALTER TABLE temp_tb DROP col_x;
SELECT * FROM temp_tb;
Here the col_x is the column which u dont want to include in select statement.
Take a look at this question : Select all columns except one in MySQL?
You can retrieve the list of column name by simple query and then remove those column by apply where query like this.
SELECT * FROM (
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = N'TableName'
) AS allColumns
WHERE allColumns.COLUMN_NAME NOT IN ('unwantedCol1', 'unwantedCol2')
If you are using DataGrip you can do the following:
Enter your SELECT statement SELECT * FROM <your_table>;
Put your cursor over * and press Alt+Enter
You will get pop up menu with Expand column list option
Click on it and it will convert * with full list of columns
Now you can remove columns that you don't need
Here is a link for an example on how to do it.
Without creating new table you can do simply (e.g with mysqli):
get all columns
loop through all columns and remove wich you want
make your query
$r = mysqli_query('SELECT column_name FROM information_schema.columns WHERE table_name = table_to_query');
$c = count($r); while($c--) if($r[$c]['column_name'] != 'column_to_remove_from_query') $a[] = $r[$c]['column_name']; else unset($r[$c]);
$r = mysqli_query('SELECT ' . implode(',', $a) . ' FROM table_to_query');
Try the following query:
DECLARE #Temp NVARCHAR(MAX);
DECLARE #SQL NVARCHAR(MAX);
SET #Temp = '';
SELECT #Temp = #Temp + COLUMN_NAME + ', ' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME ='Person' AND COLUMN_NAME NOT IN ('Id')
SET #SQL = 'SELECT ' + SUBSTRING(#Temp, 0, LEN(#Temp)) +' FROM [Person]';
EXECUTE SP_EXECUTESQL #SQL;
In your case, expand columns of that database in the object explorer. Drag the columns in to the query area.
And then just delete one or two columns which you don't want and then run it. I'm open to any suggestions easier than this.
Only one way to achieve this giving column name. There is no other method found. You must have to list all column name

How can I exclude GUIDs from a select distinct without listing all other columns in a table?

So let's say 'table' has two columns that act as a GUID - the ID column and msrepl_tran_version. Our original programmer did not know that our replication created this column and included it in a comparison, which has resulted in almost 20,000 records being put into this table, of which only 1,588 are ACTUALLY unique, and it's causing long load times.
I'm looking for a way to exclude the ID and replication columns from a select distinct, without having to then list every single column in the table, since I'm going to have to select from the record set multiple times to fix this (there are other tables affected and the query is going to be ridiculous) I don't want to have to deal with my code being messy if I can help it.
Is there a way to accomplish this without listing all of the other columns?
Select distinct {* except ID, msrepl_tran_version} from table
Other than (where COL_1 is ID and COL_N is the replication GUID)
Select distinct COL_2, ..., COL_N-1, COL_N+1, ... from table
After more searching, I found the answer:
SELECT * INTO #temp FROM table
ALTER TABLE #temp DROP COLUMN id
ALTER TABLE #temp DROP COLUMN msrepl_tran_version
SELECT DISTINCT * FROM #temp
This works for what I need. Thanks for the answers guys!
Absolutely, 100% not possible, there is no subtract columns instruction.
It can't be done in the spirit of the OP's initial question. However, it can be done with dynamic sql:
--Dynamically build list of column names.
DECLARE #ColNames NVARCHAR(MAX) = ''
SELECT #ColNames = #ColNames + '[' + c.COLUMN_NAME + '],'
FROM INFORMATION_SCHEMA.COLUMNS c
WHERE c.TABLE_SCHEMA = 'dbo'
AND c.TABLE_NAME = 'YourTable'
--Exclude these.
AND c.COLUMN_NAME NOT IN ('ID', 'msrepl_tran_version')
--Keep original column order for appearance, convenience.
ORDER BY c.ORDINAL_POSITION
--Remove trailing comma.
SET #ColNames = LEFT(#ColNames, LEN(#ColNames) - 1)
--Verify query
PRINT ('SELECT DISTINCT ' + #ColNames + ' FROM [dbo].[YourTable]')
--Uncomment when ready to proceed.
--EXEC ('SELECT DISTINCT ' + #ColNames + ' FROM [dbo].[YourTable]')
One additional note: since you need to select from the record set multiple times and potentially join to other tables, you can use the above to create a view on the table. This should make your code fairly clean.

How to select some particular columns from a table if the table has more than 100 columns

I need to select 90 columns out of 107 columns from my table.
Is it possible to write select * except( column1,column2,..) from table or any other way to get specific columns only, or I need to write all the 90 columns in select statement?
You could generate the column list:
select name + ', '
from sys.columns
where object_id = object_id('YourTable')
and name not in ('column1', 'column2')
It's possible to do this on the fly with dynamic SQL:
declare #columns varchar(max)
select #columns = case when #columns is null then '' else #columns + ', ' end +
quotename(name)
from sys.columns
where object_id = object_id('YourTable')
and name not in ('column1', 'column2')
declare #query varchar(max)
set #query = 'select ' + #columns + ' from YourTable'
exec (#query)
No, there's no way of doing * EXCEPT some columns. SELECT * itself should rarely, if ever, be used outside of EXISTS tests.
If you're using SSMS, you can drag the "columns" folder (under a table) from the Object Explorer into a query window, and it will insert all of the column names (so you can then go through them and remove the 17 you don't want)
There is no way in SQL to do select everything EXCEPT col1, col2 etc.
The only way to do this is to have your application handle this, and generate the sql query dynamically.
You could potentially do some dynamic sql for this, but it seems like overkill. Also it's generally considered poor practice to use SELECT *... much less SELECT * but not col3, col4, col5 since you won't get consistent results in the case of table changes.
Just use SSMS to script out a select statement and delete the columns you don't need. It should be simple.
No - you need to write all columns you need. You might create an view for that, so your actual statement could use select * (but then you have to list all columns in the view).
Since you should never be using select *, why is this a problem? Just drag the columns over from the Object Explorer and delete the ones you don't want.

SQL query like filter

I need to execute a search query in SQL Server where I need to filter out data based upon an user input textfield.
The problem is, this query needs to be executed on several tables (so I only know the tablecolumns at runtime).
This is the query I have:
SELECT * FROM [BTcegeka.C2M].[dbo].[Lookup_Country] WHERE Name LIke '%test%'
Now the problem is I need to do the Like function on every column (I only know the columnname at runtime) in the table. I am calling this query from an ASP.NET website. The user selects a table from a dropdownlist and can then enter the search field.
This is what I really want to accomplish:
SELECT * FROM [BTcegeka.C2M].[dbo].[Lookup_Country] WHERE * LIke '%test%'
Obviously 'Where * Like' Fails. How can I accomplish this?
You can query all columns in a table like:
select name from sys.columns where object_id = object_id('YourTable')
Then you can construct a query that does a like for each column.
Another approach is to create a calculated column called SearchField that contains a concatenation of all strings you'd like to search for. Then you can search like:
create table #tmp (id int identity, col1 varchar(10), col2 varchar(10),
SearchField as col1 + '|' + col2 persisted)
insert #tmp (col1, col2) values
('alfa', 'beta'),
('gamma', 'DELTA'),
('GAMMA', 'delta')
select * from #tmp where SearchField like '%alfa%'
Try using your SQL query like this.
SELECT * FROM [BTcegeka.C2M].[dbo].[Lookup_Country]
WHERE
COL1 LIke '%test%'
OR COL2 LIke '%test%'
OR COL3 LIke '%test%'
You may use AND instead of OR if your requirement needs that.
If you know the column names at run time, then you should build you query in .NET before passing it to sql. You can build it with the correct column name. This way you can account also for the type of the column you search in.
Careful though this path you chose is prone to SQL injection so before sending a query to the SQL you should check it.
If you really need to do this you can search in sqlserver meta tables and find the description of selected user table. Make a good use of this data is easy and you can make any sql you want with this information, but performance may not the that good
you have to use dynamic sql for implementing this. Your column name needs to be passed as parameter to this stored procedure or if you dont want to create stored procedure just declare one paramter and assign the value selected from the drop down list to it and use that in the query.
create procedure sp_dynamicColumn
(
#columnName varchar(10)
)
as
begin
declare #DYNAMICSQL nvarchar(4000);
SET #DYNAMICSQL = 'Select * from [BTcegeka.C2M].[dbo].[Lookup_Country] where '+ #columnName + ' like ''%test%'''
EXECUTE SP_EXECUTESQL #DYNAMICSQL
end
go
