Hi All,
I have migrated an SSIS package from2008 where it runs absolutely fine, to SQL 2012 where it just won't run.
Using SP_WHO2 I have found that sys.sp_describe_first_result_set is being blocked by itself (ie the SQL that is being fed to find the metadata) and this is being generated by a lookup in the dataflow.
I understand that this is a new system stored procedure but why is it causing this to happen??
Admittedly the package is using transactions throughout - but this works absolutely fine in 2008 - relevant components are using the same connection with RetainSameConnection?
Help would be greatly appreciated - I could get round this by doing a Join but hey - there should be no need!
