ORA-14551错误是当你在查询中尝试执行DML操作时会出现的错误。
ORA-14551 “cannot perform a DML operation inside a query” 说明查询内不允许执行DML操作。
在查询中,有时会下错误“ORA-14551:不能在查询中执行DML操作”。这是由于尝试在查询中执行DML操作(例如INSERT,UPDATE或DELETE)造成的。
1.确认是否有试图在查询中执行DML操作,并检查语法。
3.考虑将DML操作的结果存储在表中,然后用该表操作进行后续查询。
4.根据应用需求,也可以使用存储过程或函数实现DML操作,其查询结果可以在调用存储过程或函数时使用。
