In this optional Transaction mode, the Embedded SQL syntax is the same as that used in Transact-SQL. The begin transaction statement explicitly initiates transactions.
The syntax of the Embedded SQL transaction statements is:
exec sql [at connect_name ]
begin transaction [ transaction_name ];
exec sql [at connect_name]
save transaction [ savepoint_name];
exec sql [at connect_name] commit transaction
[ transaction_name ];
exec sql [at connect_name] rollback transaction
[ savepoint_name | transaction_name ];
The disconnect command rolls back
all open transactions. For details on this statement, see Chapter 5, “Connecting to Adaptive Server.”
When you issue a begin transaction on a connection, you must also issue a save, commit, or roll back transaction on the same connection. Otherwise, an error is generated.
