(PHP 5.3.2, PECL OCI8 >= 1.4.0)
oci_set_edition — Sets the database edition
Beschreibung
Sets the database "edition" of objects to be used by a subsequent connections.
Oracle Editions allow concurrent versions of applications to run using the same schema and object names. This is useful for upgrading live systems.
Call oci_set_edition() before calling oci_connect(), oci_pconnect() or oci_new_connect().
If an edition is set that is not valid in the database, connection will fail even if oci_set_edition() returns success.
When using persistent connections, if a connection with the requested edition setting already exists, it is reused. Otherwise, a different persistent connection is created
Parameter-Liste
- edition
-
Oracle Database edition name previously created with the SQL "CREATE EDITION" command.
Anmerkungen
Hinweis: Oracle version requirement
This function is available from Oracle 11gR2 onwards.
To avoid inconsistencies and unexpected errors, do not use ALTER SESSION SET EDITION to change the edition on persistent connections.
