Try executing:
SET QUOTED_IDENTIFIER ON
GO


first.

Apparently, the author assumed this setting was already on, though it is not normally on and a bad practice in any event, IMHO.

Even with SET QUOTED_IDENTIFIER ON, it doesnot compile. The query analyzer returns the following error message.

Server: Msg 207, Level 16, State 3, Procedure sp_DataAsInsCommand, Line 27
Invalid column name 'SELECT 'INSERT INTO '.
Server: Msg 207, Level 16, State 1, Procedure sp_DataAsInsCommand, Line 27
Invalid column name ' VALUES (' + '.

My bad, I got it backwards. Try:

SET QUOTED_IDENTIFIER OFF


instead.

Didn't execute for me with either
SET QUOTED_IDENTIFIER OFF
or
SET QUOTED_IDENTIFIER ON

No good reason to use double quotes in this stored proc.

"SET QUOTED_IDENTIFIER OFF" works fine for me. What error do you get now?

Sorry, I moved on and banged out my own Insert-generating code using Information_Schema views instead of sysobjects and syscolumns.

I needed code to 1) generate conventional Inserts, 2) create and populate a table variable w/ Inserts, or 3) create a resultset by generating one Select stmt per table row, then sticking "UNION" between each Select.

I think the error I got from this guy's proc was "Invalid column name", or something like that. Might have been due to spaces in some of my table's column names...

Thanks for offering to help. I shouldn't have complained a/b this guy's code when I didn't need it anyway.
