oci_set_edition

(PHP 5.3.2, PECL OCI8 >= 1.4.0)

oci_set_editionSets the database edition

説明

bool oci_set_edition ( string $edition )

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

パラメータ

edition

Oracle Database edition name previously created with the SQL "CREATE EDITION" command.

注意

注意: Oracle version requirement
This function is available from Oracle 11gR2 onwards.

警告

Persistent connections

To avoid inconsistencies and unexpected errors, do not use ALTER SESSION SET EDITION to change the edition on persistent connections.

返り値

成功した場合に TRUE を、失敗した場合に FALSE を返します。
