I got thousand of strings that contains data and with id's that is marked with a '#xx'. If the string has a '|' it menas that there is more data with an ID.
How do I find and replace all ID's that contains a specific ID? If I want to change #1 to #24 I don't want #11 to be changed to #241
Some exampels with expected output:
21600-39600#1 -> 21600-39600#24
21600-39600#2 -> 21600-39600#2
21600-39600#7|39600-52200#11|68000-72200#1 -> 21600-39600#7|39600-52200#11|68000-72200#24
Replace(column, '#1', '#24') will not work because #11 will be changed to #241. So I need to know if it is the end of the string or if it ends with an '|'
Quick and dirty but you could just do something like:
-- Update the end bits
UPDATE table
SET field = LEFT('field', LEN('field') -2) + '#24'
WHERE field LIKE '%#1';
-- Update the in between bits
UPDATE table
SET field = REPLACE(field, '#1|', '#24|')
WHERE field LIKE '%#1|%'; -- This where statement is optional due to the nature of the REPLACE.
Otherwise you'll have to look into the magical world of REGEX. If this is something you'd want to run more than once, I'd surely look into that. If this is just a one-time-fix-thingy, meh. It's thursday, I'd call it a valid excuse.
Try this
declare #t table(col varchar(100))
insert into #t
select '21600-39600#1' union all
select '21600-39600#2' union all
select '21600-39600#7|39600-52200#11|68000-72200#1'
select col,case when new_col like '%|' then
substring(new_col,1,len(new_col)-1)
else
new_col end as new_col
from
(
select col,
case when col+'|' like '%#1|%' then
Replace(col+'|', '#1|', '#24|') else col end as new_col
from #t
) as t
Result
col new_col
--------------------------------------------- ------------
21600-39600#1 21600-39600#24
21600-39600#2 21600-39600#2

I have a table like:
ID NAME
----------------
35 File.png
What I want to do is update that record as:
ID NAME
----------------
35 File_35.png
I have this:
DECLARE arch_cursor CURSOR FOR SELECT Id from dbo.Archivos WHERE Nombre LIKE ('%' + #Id_Relacion_Articulo_Archivo + '%')
OPEN contact_cursor;
FETCH NEXT FROM arch_cursor
INTO #Id_cur
WHILE(##FETCH_STATUS = 0 )

I know that STUFF statement can do something like put a string on a specific place of the string, but somebody know how to specify "insert string before "." without losing the left chars too?"
select id
, concat(left(name, charindex('.', name)-1), '_', id, RIGHT(name,(CHARINDEX('.', name))-1)) NAME
from test
Here is a demo
Also you can do it with a replace:
select id
, replace(name, '.', concat('_',id,'.'))
from test
And here is the one option you can use if you will look from the right (first occurrence of the character '.'):
select id
, concat(substring(name, 1, len(name)-charindex('.', (reverse(name))))
, '_'
, id
, substring(name, len(name)-charindex('.', (reverse(name)))+1, charindex('.', (reverse(name)))))
from test
Here is a demo where you can see all 3 of this examples in action with this two rows of data:
insert into test values (35, 'File.png')
insert into test values (55,
'File.File.png')
If no files can have a . in the name (apart from to denote the extension) I find STUFF easiest for this:
SELECT ID, [Name],
STUFF([Name], CHARINDEX('.',[Name]),0,CONCAT('_',ID)) AS NewName
FROM (VALUES(35,'File.png'))V(ID,[Name]);
If there could be multiple . characters and it needs to prior to the last one, you have to use the (expensive) function REVERSE:*
SELECT ID, [Name],
STUFF([Name], LEN([Name]) - CHARINDEX('.',REVERSE([Name]))+1,0,CONCAT('_',ID)) AS NewName
FROM (VALUES(35,'File.png'),(36,'File.2.png'))V(ID,[Name])
Also, don't loop. Just do this in a set based method. You're using a RDBMS, not a Programming Language:
UPDATE dbo.YourTable
SET File = STUFF([Name], CHARINDEX('.',[Name]),0,CONCAT('_',ID));
I am trying to parse out certain data from a string and I am having issues.
Here is the string:
1=BETA.1.0^2=175^3=812^4=R^5=N^9=1^12=1^13=00032^14=REP NOT FOUND ON REP TABLE, CANNOT INSERT TO REPRGR.^10=107~117~265~1114~3143~3505~3506~3513~5717^11=SA16~1~WY~WY~A~S~20100210~001~SE62^-omitted due to existing Rep Not Found
I need to return this "REP NOT FOUND ON REP TABLE, CANNOT INSERT TO REPRGR."
Here is my query SELECT CONVERT(VARCHAR(5000),CHARINDEX('14=',Column))FROM Table
If you're parsing, can we assume that you don't know what might come after the '^14=', but you need to capture whatever does? So searching for a particular string won't work because anything could come after '^14='. The best approach is to identify the longest reliable specific string that gives you a "foothold" to find the data you're looking for. What you don't want to do is accidentally capture the wrong data if the '^14=' appears more than once in your string. It looks like the '^' is your delimiter, since I don't see one at the start of the string. So you were actually on the right track, you just need to use SUBSTRING as a commenter mentioned. You also need to identify a marker for the end of the error message, which looks like it might be the next occurring '^', correct? Check several samples to be sure of this, and make sure the end marker doesn't at any point exist before your start marker or you'll get an error.
SELECT CAST((SUBSTRING(Column,CHARINDEX('14=',Column,0),CHARINDEX('^',Column,CHARINDEX('14=',Column,0) + 1) - CHARINDEX('14=',Column,0))) AS VARCHAR(5000)) FROM Table
You may need to increment or decrement the start position and end position by doing a +1 or -1 to fully capture your error message. But this should dynamically grab any length error message provided you are positive of your starting and ending markers.
I also have here a table-valued parsing function, where you would pass it the string and the '^' and it will return a table of data with not only the 14=, but everything.
CREATE function [dbo].[fn_SplitStringByDelimeter]
(
#list nvarchar(8000)
,#splitOn char(1)
)
returns #rtnTable table
(
id int identity(1,1)
,value nvarchar(100)
)
as
begin
declare #index int
declare #string nvarchar(4000)
select #index = 1
if len(#list) < 1 or #list is null return
--
while #index!= 0
begin
set #index = charindex(#splitOn,#list)
if #index!=0
set #string = left(#list,#index - 1)
else
set #string = #list
if(len(#string)>0)
insert into #rtnTable(value) values(#string)
--
set #list = right(#list,len(#list) - #index)
if len(#list) = 0 break
end
return
end
It sounds like you're trying to get the value of argument 14. This should do it:
select substring(
someData
, charindex('^14=',someData) + 4
, charindex('^',someData, charindex('^14=',someData) + 4) - charindex('^14=',someData) - 4
) errorMessage
from myData
where charindex('^14=',someData) > 0
and charindex('^',someData, charindex('^14=',someData) + 4) > 0
Try it here: http://sqlfiddle.com/#!18/22f23/2
This gets a substring of the given input.
The substring starts at the first character after the string ^14=; i.e. we get the index of ^14= in the string, then add 4 to it to skip over the matched characters themselves.
The substring ends at the first ^ character after the one in ^14=. We get the index of that character, then subtract the starting position from it to get the length of the desired output.
Caveats: If there is no parameter (^) after ^14= this will not work. Equally if there is no ^14= (even if the string starts 14=) this will not work. From the information available that's OK; but if this is a concern please say and we can provide something to handle that more complex scenario.
Code to create table & populate demo data
create table myData (someData nvarchar(256))
insert myData (someData)
values ('1=BETA.1.0^2=175^3=812^4=R^5=N^9=1^12=1^13=00032^14=REP NOT FOUND ON REP TABLE, CANNOT INSERT TO REPRGR.^10=107~117~265~1114~3143~3505~3506~3513~5717^11=SA16~1~WY~WY~A~S~20100210~001~SE62^-omitted due to existing Rep Not Found')
, ('1xx^14=something else.^10=xx')
You could try to use a Case When statement with wildcards to find the value that you want.
Example:
SELECT
CASE
WHEN x LIKE '%REP Not Found%'
THEN 'REP NOT FOUND ON REP TABLE, CANNOT INSERT TO REPRGR'
ELSE
''
END AS x
FROM
#T1
You could use this query (assuming MySQL database):
-- item is the column that contains the string
select SUBSTR(item, LOCATE('REP',item), LOCATE('REPRGR.',item) + LENGTH('REPRGR.') - LOCATE('REP', item)) info_msg from Table;
Illustration:
create table parsetest (item varchar(5000));
insert into parsetest values('1=BETA.1.0^2=175^3=812^4=R^5=N^9=1^12=1^13=00032^14=REP NOT FOUND ON REP TABLE, CANNOT INSERT TO REPRGR.^10=107~117~265~1114~3143~3505~3506~3513~5717^11=SA16~1~WY~WY~A~S~20100210~001~SE62^-omitted due to existing Rep Not Found');
select * from parsetest;

I need to do a select in a column that contains a query string like:
user_id=300&company_id=201503&status=WAITING OPERATION&count=1
I want to perform a select and break each value in a new column, something like:
user_id | company_id | status | count
300 | 201503 | WAITING OPERATION | 1
How can i do it in SQL Server without use procs?
I've tried a function:
CREATE FUNCTION [xpto].[SplitGriswold]
(
#List NVARCHAR(MAX),
#Delim1 NCHAR(1),
#Delim2 NCHAR(1)
)
RETURNS TABLE
AS
RETURN
(
SELECT
Val1 = PARSENAME(Value,2),
Val2 = PARSENAME(Value,1)
FROM
(
SELECT REPLACE(Value, #Delim2, '&') FROM
(
SELECT LTRIM(RTRIM(SUBSTRING(#List, [Number],
CHARINDEX(#Delim1, #List + #Delim1, [Number]) - [Number])))
FROM (SELECT Number = ROW_NUMBER() OVER (ORDER BY name)
FROM sys.all_objects) AS x
WHERE Number <= LEN(#List)
AND SUBSTRING(#Delim1 + #List, [Number], LEN(#Delim1)) = #Delim1
) AS y(Value)
) AS z(Value)
);
GO
Execution:
select QueryString
from User.Log
CROSS APPLY notifier.SplitGriswold(REPLACE(QueryString, ' ', N'ŏ'), N'ŏ', '&') AS t;
But it returns me only one column with all inside:
QueryString
user_id=300&company_id=201503&status=WAITING OPERATION&count=1
Thanks in advance.
I've had to do this many times before, and you're in luck! Since you only have 3 delimiters per string, and that number is fixed, you can use SQL Server's PARSENAME function to do it. That's far less ugly than the best alternative (using the XML parsing stuff). Try this (untested) query (replace TABLE_NAME and COLUMN_NAME with the appropriate names):
SELECT
PARSENAME(REPLACE(COLUMN_NAME,'&','.'),1) AS 'User',
PARSENAME(REPLACE(COLUMN_NAME,'&','.'),2) AS 'Company_ID',
PARSENAME(REPLACE(COLUMN_NAME,'&','.'),3) AS 'Status',
PARSENAME(REPLACE(COLUMN_NAME,'&','.'),4) AS 'Count',
FROM TABLE_NAME
That'll get you the results in the form "user_id=300", which is far and away the hard part of what you want. I'll leave it to you to do the easy part (drop the stuff before the "=" sign).
NOTE: I can't remember if PARSENAME will freak out over the illegal name character (the "=" sign). If it does, simply nest another REPLACE in there to turn it into something else, like an underscore.
You need to use SQL SUBSTRING as part of your select statement. You would first need to build the first row, then use a UNION to return the second row.
I have a field called zip, type char(5), which contains zip codes like
12345
54321
ABCDE
I'd like to check with an sql statement if a zip code contains numbers only.
The following isn't working
SELECT * FROM S1234.PERSON
WHERE ZIP NOT LIKE '%'
It can't work because even '12345' is an "array" of characters (it is '%', right?
I found out that the following is working:
SELECT * FROM S1234.PERSON
WHERE ZIP NOT LIKE ' %'
It has a space before %. Why is this working?
If you use SQL Server 2012 or up the following script should work.
DECLARE #t TABLE (Zip VARCHAR(10))
INSERT INTO #t VALUES ('12345')
INSERT INTO #t VALUES ('54321')
INSERT INTO #t VALUES ('ABCDE')
SELECT *
FROM #t AS t
WHERE TRY_CAST(Zip AS NUMERIC) IS NOT NULL
Using answer from here to check if all are digit
SELECT col1,col2
FROM
(
SELECT col1,col2,
CASE
WHEN LENGTH(RTRIM(TRANSLATE(ZIP , '*', ' 0123456789'))) = 0
THEN 0 ELSE 1
END as IsAllDigit
FROM S1234.PERSON
) AS Z
WHERE IsAllDigit=0
DB2 doesnot have regular expression facility like MySQL REGEXP
USE ISNUMERIC function;
ISUMERIC returns 1 if the parameter contains only numbers and zero if it not
EXAMPLE:
SELECT * FROM S1234.PERSON
WHERE ISNUMERIC(ZIP) = 1
Your statement doesn't validate against numbers but it says get everything that doesn't start with a space.
Let's suppose you ZIP code is a USA zip code, composed by 5 numbers.
db2 "with val as (
select *
from S1234.PERSON t
where xmlcast(xmlquery('fn:matches(\$ZIP,''^\d{5}$'')') as integer) = 1
)
select * from val"
For more information about xQuery:fn:matches: http://pic.dhe.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.xml.doc/doc/xqrfnmat.html
mySql does not have a native isNumberic() function. This would be pretty straight-forward in Excel with the ISNUMBER() function, or in T-SQL with ISNUMERIC(), but neither work in MySQL so after a little searching around I came across this solution...
SELECT * FROM S1234.PERSON
WHERE ZIP REGEXP ('[0-9]')
Effectively we're processing a regular expression on the contents of the 'ZIP' field, it may seem like using a sledgehammer to crack a nut and I've no idea how performance would differ from a more simple approach but it worked and I guess that's the point.
I have made more error-prone version based on the solution https://stackoverflow.com/a/36211270/565525, added intermedia result, some examples:
select
test_str
, TRIM(TRANSLATE(replace(trim(test_str), ' ', 'x'), 'yyyyyyyyyyy', '0123456789'))
, case when length(TRIM(TRANSLATE(replace(trim(test_str), ' ', 'x'), 'yyyyyyyyyyy', '0123456789')))=5 then '5-digit-zip' else 'not 5d-zip' end is_zip
from (VALUES
(' 123 ' )
,(' abc ' )
,(' a12 ' )
,(' 12 3 ')
,(' 99435 ')
,('99323' )
) AS X(test_str)
;
The result for this example set is:
TEST_STR 2 IS_ZIP
-------- -------- -----------
123 yyy not 5d-zip
abc abc not 5d-zip
a12 ayy not 5d-zip
12 3 yyxy not 5d-zip
99435 yyyyy 5-digit-zip
99323 yyyyy 5-digit-zip
Try checking if there's a difference between lower case and upper case. Numerics and special chars will look the same:
SELECT *
FROM S1234.PERSON
WHERE UPPER(ZIP COLLATE Latin1_General_CS_AI ) = LOWER(ZIP COLLATE Latin1_General_CS_AI)
Here's a working example for the case where you'd want to check zip codes in a range. You could use this code for inspiration to make a simple single post code check, if you want:
if local_test_environment?
# SQLite supports GLOB which is similar to LIKE (which it only has limited support for), for matching in strings.
where("(zip_code NOT GLOB '*[^0-9]*' AND zip_code <> '') AND (CAST(zip_code AS int) >= :range_start AND CAST(zip_code AS int) <= :range_finish)", range_start: range_start, range_finish: range_finish)
else
# SQLServer supports LIKE with more advanced matching in strings than what SQLite supports.
# SQLServer supports TRY_PARSE which is non-standard SQL, but fixes the error SQLServer gives with CAST, namely: Conversion failed when converting the nvarchar value 'US-19803' to data type int.
where("(zip_code NOT LIKE '%[^0-9]%' AND zip_code <> '') AND (TRY_PARSE(zip_code AS int) >= :range_start AND TRY_PARSE(zip_code AS int) <= :range_finish)", range_start: range_start, range_finish: range_finish)
end
Use regex.
SELECT * FROM S1234.PERSON
WHERE ZIP REGEXP '\d+'
In my database (SQL 2005) I have a field which holds a comment but in the comment I have an id and I would like to strip out just the id, and IF possible convert it to an int:
activation successful of id 1010101
The line above is the exact structure of the data in the db field.
And no I don't want to do this in the code of the application, I actually don't want to touch it, just in case you were wondering ;-)
This should do the trick:
SELECT SUBSTRING(column, PATINDEX('%[0-9]%', column), 999)
FROM table
Based on your sample data, this that there is only one occurence of an integer in the string and that it is at the end.
I don't have a means to test it at the moment, but:
select convert(int, substring(fieldName, len('activation successful of id '), len(fieldName) - len('activation successful of id '))) from tableName
Would you be open to writing a bit of code? One option, create a CLR User Defined function, then use Regex. You can find more details here. This will handle complex strings.
If your above line is always formatted as 'activation successful of id #######', with your number at the end of the field, then:
declare #myColumn varchar(100)
set #myColumn = 'activation successful of id 1010102'
SELECT
#myColumn as [OriginalColumn]
, CONVERT(int, REVERSE(LEFT(REVERSE(#myColumn), CHARINDEX(' ', REVERSE(#myColumn))))) as [DesiredColumn]
Will give you:
OriginalColumn DesiredColumn
---------------------------------------- -------------
activation successful of id 1010102 1010102
(1 row(s) affected)
select cast(right(column_name,charindex(' ',reverse(column_name))) as int)
CAST(REVERSE(LEFT(REVERSE(#Test),CHARINDEX(' ',REVERSE(#Test))-1)) AS INTEGER)
-- Test table, you will probably use some query
DECLARE #testTable TABLE(comment VARCHAR(255))
INSERT INTO #testTable(comment)
VALUES ('activation successful of id 1010101')
-- Use Charindex to find "id " then isolate the numeric part
-- Finally check to make sure the number is numeric before converting
SELECT CASE WHEN ISNUMERIC(JUSTNUMBER)=1 THEN CAST(JUSTNUMBER AS INTEGER) ELSE -1 END
FROM (
select right(comment, len(comment) - charindex('id ', comment)-2) as justnumber
from #testtable) TT
I would also add that this approach is more set based and hence more efficient for a bunch of data values. But it is super easy to do it just for one value as a variable. Instead of using the column comment you can use a variable like #chvComment.
If the comment string is EXACTLY like that you can use replace.
select replace(comment_col, 'activation successful of id ', '') as id from ....
It almost certainly won't be though - what about unsuccessful Activations?
You might end up with nested replace statements
select replace(replace(comment_col, 'activation not successful of id ', ''), 'activation successful of id ', '') as id from ....
[sorry can't tell from this edit screen if that's entirely valid sql]
That starts to get messy; you might consider creating a function and putting the replace statements in that.
If this is a one off job, it won't really matter. You could also use a regex, but that's quite slow (and in any case mean you now have 2 problems).
