Hi,

just a start: you can use SQL Server's sp_executesql SP or the EXECUTE to execute dynamic SQL. To find out the PK you can use sp_primarykeys. See BOL or MSDN Library for more details.

>Let's call one procedure (a function really) IsSameSchool with four parameters: Name of table1, Value of PK for table1, Name of table2 and Value of PK for table2. The function already knows the name of the field that contains the school's FK. Let the function figure out which is the PK of each table. I think this requires the equivalent of a macro, and I don't know whether T-SQL even allows that.
