ORA-00918: columns not explicitly defined

Source: Internet
Author: User

There is an SQL statement, similar to the following:

Select..., createdate from A left join B on... where...

The createdate field exists in both table A and table B. The local Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 runs normally, and the value displayed in createdate is the information of this field in table B.

But at the customer site, the Database version is Oracle Database 11g Enterprise Edition Release 11.2.0.1.0, the above statement reported error: ORA-00918: not clearly defined Column

It seems that the Oracle version is different, and the solution to this problem is also different.
