ingres_rollback -- Roll back a transaction
Description
bool 
ingres_rollback ( [resource link] )
     ingres_rollback() rolls back the currently
     open transaction, actually canceling all changes made to the
     database during the transaction.
    
     This closes the transaction. A new one can be open by sending a
     query with ingres_query().
