ZF-7629: Zend_Db_Adapter_Pdo_Mssql should pass @table_owner to sp_pkeys
In mssql if you don't pass variable @table_owner it will guess the table is in dbo schema. So in attachment is a patch to fix that. I'm also using that in sp_columns because is the right to do. If I have a 2 tables with the same name and different schemas, that will be confusing.
