Concatenating rows from different tables into one field
- by Markus
Hi!
In a project using a MSSQL 2005 Database we are required to log all data manipulating actions in a logging table. One field in that table is supposed to contain the row before it was changed. We have a lot of tables so I was trying to write a stored procedure that would gather up all the fields in one row of a table that was given to it, concatenate them somehow and then write a new log entry with that information.
I already tried using FOR XML PATH and it worked, but the client doesn't like the XML notation, they want a csv field.
Here's what I had with FOR XML PATH:
DECLARE @foo varchar(max);
SET @foo = (SELECT * FROM table WHERE id = 5775 FOR XML PATH(''));
The values for "table", "id" and the actual id (here: 5775) would later be passed in via the call to the stored procedure.
Is there any way to do this without getting XML notation and without knowing in advance which fields are going to be returned by the SELECT statement?
