invalid column name using sp_msforeachdb

Hi
I'm having a problem with sp_msforeachdb throwing an error "Invalid column name 'USERCREATED'."
For the purpose of example, I've stripped back what I'm actually trying to achieve to this:

execute sp_msforeachdb 'if ((''?'' LIKE ''%CoLive'') or (''?'' LIKE ''%CoData''))
BEGIN
USE [?]
print ''?''
select ''?'' AS DBNAME,USERID,USERCREATED FROM USERS
END
'
Running this in SSMS the Results tab includes all three columns for both databases that match the LIKE selection. In the Messages tab I get the aforementioned error.

Thanks

Try this approach:

execute sp_msforeachdb '
USE [?]
IF ((DB_NAME() LIKE ''%CoLive'') OR (DB_NAME() LIKE ''%CoData''))
BEGIN
PRINT ''?''
SELECT ''?'' AS DBNAME,USERID,USERCREATED FROM USERS
END
'

Sorry, no, it still doesn't work. I also tried replacing the other instances of '?' with DB_NAME()

Here's 2 interesting things.

1. Without the USERCREATED column the query runs fine (note ONLY the DemoDataV90CoData and DemoDataV90CoLive databases are ever listed)

2. I have a MSRS database "ReportServer". This happens to have a Users table and a UserId column. I took the database offline and the query ran without errors.

There are plenty of other databases loaded and they don't have a Users table at all.

What is the result set of following query?
USE DemoDataV90CoLive
SELECT * FROM sys.columns
where [object_id] = OBJECT_ID('USERS')

Sorry, my mistake. I put wrong code, 'cose of my wife ;)
Try this:

execute sp_msforeachdb '
USE ?
IF EXISTS (SELECT * FROM sys.columns
where [object_id] = OBJECT_ID(''USERS''))
BEGIN
SELECT DB_NAME(),* FROM sys.columns
where [object_id] = OBJECT_ID(''USERS'') AND name LIKE ''USERCREATED''
END
ELSE
PRINT CAST (DB_NAME() AS VARCHAR(100))+'' Has no such an object'''

I've tried adding a Users table to another database with a mixture of column names, and it seems there's an error message for each column in the query which doesn't exist in the Users table. If there is no Users table there are no errors.

But, the whole point of the LIKE filter is to skip irrelevant databases. Even if the LIKE wasn't working properly one would expect to see every database name in the output - which one doesn't.

This is just nuts!!!

Ok, try this:
execute sp_msforeachdb '
USE [?]
IF ((DB_NAME() LIKE ''%CoLive'' OR DB_NAME() LIKE ''%CoData'') AND DB_NAME() NOT LIKE ''%ReportServer%'')
BEGIN
PRINT ''?''
SELECT ''?'' AS DBNAME,USERID,USERCREATED FROM USERS
END
'

This one should fix your problem ;)

DECLARE @cmd1 VARCHAR(500)
SET @cmd1='IF (''?'' LIKE ''%CoLive'' OR ''?'' LIKE ''%CoData'') EXECUTE (''USE ? SELECT DB_NAME() AS DBNAME, USERID, USERCREATED FROM USERS'')'
EXEC sp_msforeachdb @command1=@cmd1

Sorry, clicked, to quickly... Thanks for solving that. I wouldn't have figured that one out myself. What is it that's different that makes it work? Why didn't it work any way?

Thanks again
Jeremy

If any of databases has users table whole query was evaluated regardless of if clause.
This approach eliminates this evaluation.

Take care,
