I want to select all data from a table (all data in table were encrypted) in postgresql database. But can't get all data.Query only works with condition. This query works. select pgp_sym_decrypt(name::bytea,'code'), pgp_sym_decrypt(surname::bytea,'code'), pgp_sym_decrypt(context::bytea,'code') from schema.table_name where id=1;
But I want to use this query : select pgp_sym_decrypt(name::bytea,'code'), pgp_sym_decrypt(surname::bytea,'code'), pgp_sym_decrypt(context::bytea,'code') from schema.table_name;
How can I get all data?

Below is how I structured the data in BigQuery database.
test
-> sales
-> monthly-2015
-> monthly-2016
-> ...
I want to combine the data of all tables with the table name , monthly-*, and below is how I wrote the sql from examples I found.
Running this sql leads an error like following Scalar subquery produced more than one element. How could I fix it to error?
SELECT
*,
(
SELECT
table_id
FROM
`test.sales.__TABLES_SUMMARY__`
WHERE
table_id LIKE 'monthly-%')
FROM
`test.sales.monthly*`
I want to combine the data of all tables with the table name , monthly-*
Try below
SELECT *, 'monthly_' || _TABLE_SUFFIX as table_name
FROM `test.sales.monthly_*`
I am currently working with a MS SQL database on Windows 2012 Server
I need to query only 1 column from a table that I only have access to read, not make any kind of changes.
Problem is that the name of the column is "Value"
My code is this:
SELECT 'Value' FROM table
If I add
`ORDER BY 'Value'`
The issue is that the query is returning an empty list of results.
Things I've tried already
I tried replacing ' with `"' but this didn't work either.
I also tried writing SELECT * instead of SELECT VALUE
Using the table name in the SELECT or ORDER clauses again didn't help
You are claiming that this query:
SELECT 'Value'
FROM table
ORDER BY 'Value'
Is returning no rows. That's not quite correct. It is returning an error because SQL Server does not allow constant expressions as keys for ORDER BY (or GROUP BY for that matter).
Do not use single quotes. In this case:
SELECT 'Value' as val
FROM table
ORDER BY val;
Or, if value is a column in the table:
SELECT t.Value
FROM table t
ORDER BY t.Value;
Value is not a reserved word in SQL Server, but if it were, you could escape it:
SELECT t.[Value]
FROM table t
ORDER BY t.[Value];
it looks like your table has null values. and because of the order by all null values come first.
try to add filter like this
select Value FROM table
where Value is not null and Value <> ''
order by Value
I am fairly new to SQL, and I am hoping someone can help me with a problem I'm having. I haven't been able to find any answers helping me figure out this exact problem.
I have two tables in two SQL Server databases on two different servers that I want to compare using the column ItemID. I want to find records from Table1 that have an ItemID that does not exist in Table2 and insert those into a table variable. I have the following code:
--Create table variable to hold query results
DECLARE #ItemIDTable TABLE
(
[itemid][NVARCHAR](20) NULL
);
--Query data and insert results into table variable
INSERT INTO #ItemIDTable
([itemid])
SELECT a.[itemid]
FROM database1.dbo.table1 a
WHERE NOT EXISTS (SELECT 1
FROM [Database2].[dbo].[table2]
WHERE a.itemid = [Database2].[dbo].[table2].[itemid])
ORDER BY itemid
This works on a test server where the two databases are on the same server, but not in real life where they are on different servers. I tried the following using OPENQUERY, but I know I haven't got it quite right.
--Create table variable to hold query results
DECLARE #ItemIDTable TABLE
(
[ItemID][nvarchar](20) NULL
);
--Query data and insert results into table variable
INSERT INTO #ItemIDTable
([ItemID])
SELECT a.[ItemID]
FROM Database1.dbo.Table1 a
WHERE NOT EXISTS (SELECT 1
FROM OPENQUERY([Server2], SELECT * FROM [Database2].[dbo].[Table2]')
WHERE a.ItemID = [Database2].[dbo].[Table2].[ItemID])
ORDER BY ItemID
I'm pretty sure I need to do something in the WHERE clause, where I have the two databases on two servers, I'm just not quite sure how to structure it. Could anyone help?
You can't create an OPENQUERY that is correlated to an outer query. You could populate a temp table with the results of an OPENQUERY and do your WHERE NOT EXISTS against the temp table, or you might want to look into Synonyms.
Openquery works like this:
select *
from openquery
(LINKED_SERVER_NAME,
'select query goes here'
)
Note that the sql portion is single quoted. That means you might have to quote the quotes if necessary. For example:
select *
from openquery
(LINKED_SERVER_NAME,
'
select SomeTextField
from SomeTable
where SomeDateField = ''20141014''
'
)
I have an quite simple query
SELECT id FROM table where ID in &data
When I run this SQL I am prompted to type in some values to &data.
I would like to be able to select several id's using this. i.e. &data = "11,12,13"
but then I get an error ORA-00933.
Ive tried with:
11,12,13
'11,12,13' -> ORA-01722
'11','12','13'
Any ideas?
Try to add ():
SELECT id FROM table where ID in (&data)
the input values should be '11,12,13'
or try to add (''):
SELECT id FROM table where ID in (&data)
the input values should be 11,12,13
I am trying to update one table from another, im able to update fine as long as the customer record exists, but there are some entries that dont.
To solve this i've tried running the following insert
SELECT *
INTO SalBudgetCust
FROM SalBudgetCust_temp
WHERE NOT EXISTS (
SELECT Customer
FROM SalBudgetCust
WHERE Customer = SalBudgetCust_temp.Customer
)
but im prompted with
There is already an object named 'SalBudgetCust' in the database.
Im stuck at this point... could anyone offer a little guideance?
SELECT INTO implicitly creates the table you name. You should instead use INSERT INTO ... SELECT * FROM ..., so that the existing table is used.
It should be INSERT INTO instead of SELECT * INTO ... like
INSERT INTO SalBudgetCust SELECT * FROM SalBudgetCust_temp
WHERE NOT EXISTS
(
SELECT Customer FROM SalBudgetCust WHERE Customer = SalBudgetCust_temp.Customer
)
The general syntax to insert data of one table into another is :
INSERT INTO new_table
SELECT * FROM old_table
WHERE some_condition;
Where, new_table is the table where you want to insert data, old_table is table from where you are fetching data and some_condition is the expression / condition based upon which you want to fetch data from old table.
You may use other clauses like order by, group by, and even sub queries after where clause.
May refer this SQL INSERT INTO and it's subsequent pages.
