Is there an equivalent function in SQL Server for the oracle wm_concat.  I need to make two rows into one but cant seem to find a simple function in SQL that will allow this.

Hi,

You could use FOR XML PATH, like

SELECT ID, STUFF((SELECT ', '+t2.name AS[text()] FROM table1 t2 WHERE t2. ID =t1. ID FOR XML PATH('')), 1, 2, '') AS list
FROM table1 t1
GROUP BY t1.ID

This works for my character field there is a lot of syntax .  Is there a way to do it for a numeric field.  Ideally I would like to just have the string comma delimited if possible

Then you have to convert the numeric field to a char field.

SELECT ID, STUFF((SELECT ', '+CONVERT(varchar(10), t2.numericvalue) AS[text()] FROM table1 t2 WHERE t2. ID =t1. ID FOR XML PATH('')), 1, 2, '') AS list
FROM table1 t1
GROUP BY t1.ID

That works,  I am almost there.  Is there a way to get rid of the >,6.60000</T><T>,79.20000</T> ... I would like to get the values separated by the comma only .. eliminating the </T><T>,
