I have a table with ProductId, ItemId, PropertyId, and ValueId columns. My ValueId is a varchar(20) and happens to be the data I want pivoted under the PropertyId which would be my columns. ProductId and ItemId would be the row. Is there a way to do this with Pivot?
thanks,
vmon

Sorry, but no. The PIVOT operator requires some sort of aggregation. Whether you're averaging or summing or whatever.

Someone did post a CASE statement SELECT which is a fake pivot, though. Check out this thread: http://qa.sqlservercentral.com/Forums/Topic399930-338-1.aspx

well - for better or for worse - Min( [varchar]) returns the [varchar], so you could use that as your aggregate. Assuming you can make sure that the grouping only returns one valueID per column+row grouping, that should give you what you wish.

Totally agree with Matt and you can use either Min or Max ... just be carefull if you have Nulls !

________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
