预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

OCI_DEFAULT (integer)

Statement execution mode. Statement is not committed automatically when using this mode.

OCI_DESCRIBE_ONLY (integer)

Statement execution mode. Use this mode if you don't want to execute the query, but get the select-list's description.

OCI_COMMIT_ON_SUCCESS (integer)

Statement execution mode. Statement is automatically committed after oci_execute() call.
