Row Concatenation Tests

leave a comment »

I found an article by John Alexander Lopez in the october 07 edition of sql server mag.  He discussed how concatenating the normal way (with select statements) isn’t near as efficient as using the new ‘for xml’ method.  Here’s an example of how to use it

 declare @concattest varchar(max)

set @concattest = (select column1 + ‘,’ + column2 as [text()] from tblstores
for xml path(”))
select left(@concattest,len(@concattest)-1)
