Specifying Transaction Names When Using Commit
From InterBase
Go Up to Using COMMIT

EXEC SQL
BEGIN DECLARE SECTION;
isc_tr_handle TR1, TR2;
EXEC SQL
END DECLARE SECTION;
TR1 = (isc_tr_handle) NULL;
TR2 = (isc_tr_handle) NULL;
. . .
EXEC SQL
SET TRANSACTION NAME TR1;
EXEC SQL
SET TRANSACTION NAME TR2;
. . .

EXEC SQL
COMMIT TRANSACTION TR1;
EXEC SQL
COMMIT TRANSACTION TR2;
. . .
