PLSQL_V2_COMPATIBILITY

Property	Description
Parameter type	Boolean
Default value	`false`
Modifiable	`ALTER SESSION`, `ALTER SYSTEM`
Range of values	`true \| false`

Note:

The PLSQL_V2_COMPATIBILITY parameter is deprecated. It is retained for backward compatibility only.

PL/SQL Version 2 allows some abnormal behavior that Version 8 disallows. If you want to retain that behavior for backward compatibility, set PLSQL_V2_COMPATIBILITY to true. If you set it to false, then PL/SQL Version 8 behavior is enforced and Version 2 behavior is not allowed.
