Question

i need to collect all return data into a variable using comma separated.

let say i have a select command like: select * from #temptable.
it’s return:

Field1|Field2
-------------
Value1|Value2

Expected Result: @testvariable hold the value: ‘Value1′,’Value2’

On this table their may have 2 columns and i need to store all the return result into a single variable. We can easily collect a single value like: select @var=column1 from #temptable. But i need to store all.Here the problem is, the number of column can be vary. Mean, number of column and name of column generate from another query.So, i can’t mention the field name.I need a dynamic way to do it. on this table only one row will be return. Thanks in advance.

You can do this without dynamic SQL using XML

DECLARE @xml XML = (SELECT * FROM #temptable FOR XML PATH(''))

SELECT stuff((SELECT ',' + node.value('.', 'varchar(100)')
              FROM   @xml.nodes('/*') AS T(node)
              FOR XML PATH(''), type).value('.','varchar(max)')
              , 1, 1, ''); 

This can probably be simplified by someone more adept at XML querying than me.
