Hi
I have a table which has columns containing sales values for each month for example..
Id, versionId, jul,aug,sep,oct,nov,dec,jan,feb,mar,apr,may,jun
The 'versionId' joins to the period table which has the end dates for each month
versionId, juldate,augdate,sepdate,octdate,novdate,decdate,jandate,febdate,madater,aprdate,maydate,jundate
What i need to do is return individual rows for each month with the corresponding period date..
Id
versionId
salesvalue
salesenddate
I have been looking at Multi-Statement Table-Value Functions but haven't been able to get anywhere near this result..
Any assistance greatly appreciated..

sounds like you may need something like a pivot table query

As previously stated this does sound like a PIVOT or a cross tab. If you want some help you need to provide enough information so we can help. Please read the article on best practices found at the first link in my signature.

actually sounds more like an unpivot to normalize a data structure.
