Answer / tdguy
multistatementrequest: TD considers two or more sqls to be
processed during a single transaction. Example is BTET.
BT;
update emp set fname='tdguy';
update emp1set lname='tdguy';
ET;
Both the above sqls are considered as single transaction
and any error would lead to rollback of both the tables.
This is multistatement request.

Answer / yuvaevergreen
multi statement request consists of more than one sql
statements. Semi colon placed in middle or beginning of sql
requests identifies the multi statement request. Only DML
statements can be included in the MSR. In ansi mode, multi
statement requests are to be committed by COMMIT. In
teradata mode, explicitly by BT and ET or implicitly.
