in thread Can i execute two queries connecting to same DB at a time.
DBD::ODBC does support MAS and MARS, as documented in DBD::ODBC::FAQ. But unlike a proper RDBMS, MAS and MARS require special coding and have surprising side effects. Those problems come from the underlying communication protocol (and probably the MS SQL Server code itself) and do not exist in Oracle, PostgreSQL and other RBDMSs.
Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
