(PHP 5.3.2, PECL OCI8 >= 1.4.0)
oci_set_edition — Sets the database edition
说明 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
参数
edition
Oracle Database edition name previously created with the SQL "CREATE EDITION" command.
注释Note: Oracle version requirement
This function is available from Oracle gR2 onwards.
Caution Persistent connectionsTo avoid inconsistencies and unexpected errors, do not use ALTER SESSION SET EDITION to change the edition on persistent connections.
Caution DRCP Connection PoolingTo avoid inconsistencies and unexpected errors when using editions and DRCP with Oracle .2.0.1, keep a one-to-one correspondence between the oci8.connection_class and the edition name used by applications. Each pooled server of a given connection class should only be used with one edition. This restriction has been removed with Oracle .2.0.2.
返回值成功时返回 TRUE， 或者在失败时返回 FALSE。
