Upgrading SQL Server - xp_execresultset
SQL Server 2000 had a useful, though undocumented, function called xp_execresultset. This function takes a query that creates a set of intermediate queries. These intermediate queries are then executed. This function is especially useful when you need to execute a stored procedure against multiple rows. Unfortunately for those already using it, SQL Server 2005 has dropped this feature.
Adam Machanic has come to the rescue with ExecResultSet. This handy little proc duplicates the functionality of xp_execresultset.
