db2中无法识别保存点

Question

我有以下查询-

SAVEPOINT A ON ROLLBACK RETAIN CURSORS;
select max(id) from testdb.table1;
ROLLBACK TO SAVEPOINT A;
commit

我得到以下错误

ROLLBACK TO SAVEPOINT A
DB21034E  The command was processed as an SQL statement because it was not a 
valid Command Line Processor command.  During SQL processing it returned:
SQL0880N  SAVEPOINT "A" does not exist or is invalid in this context.  
SQLSTATE=3B001

我是DB2的新手，我没有得到任何启动事务类型的语句，但是提交是存在的。

如何解决此错误？

我得到了关注-

update command options using c OFF; 
SAVEPOINT A ON ROLLBACK RETAIN CURSORS;
select max(id) from testdb.table1;
ROLLBACK TO SAVEPOINT A;
commit;
update command options using c ON ;

在我看来，它运行良好。

commit;
