OCI8 Function and Method Modes
Constant Description
OCI_ASSOC Used with oci_fetch_all() and oci_fetch_array() to get results as an associative array.
OCI_BOTH Used with oci_fetch_all() and oci_fetch_array() to get results as an array with both associative and number indices.
OCI_COMMIT_ON_SUCCESS Statement execution mode for oci_execute() call. Automatically commit changes when the statement has succeeded.
OCI_CRED_EXT Used with oci_connect() for using Oracles' External or OS authentication. Introduced in PHP 5.3 and PECL OCI8 1.3.4.
OCI_DEFAULT See OCI_NO_AUTO_COMMIT.
OCI_DESCRIBE_ONLY Statement execution mode for oci_execute(). Use this mode if you want meta data such as the column names but don't want to fetch rows from the query.
OCI_EXACT_FETCH Obsolete. Statement fetch mode. Used when the application knows in advance exactly how many rows it will be fetching. This mode turns prefetching off for Oracle release 8 or later mode. The cursor is canceled after the desired rows are fetched which may result in reduced server-side resource usage.
OCI_FETCHSTATEMENT_BY_COLUMN Default mode of oci_fetch_all().
OCI_FETCHSTATEMENT_BY_ROW Alternative mode of oci_fetch_all().
OCI_LOB_BUFFER_FREE Used with OCI-Lob::flush to free buffers used.
OCI_NO_AUTO_COMMIT Statement execution mode for oci_execute(). The transaction is not automatically committed when using this mode. For readability in new code, use this value instead of the older, equivalent OCI_DEFAULT constant. Introduced in PHP 5.3.2 (PECL OCI8 1.4).
OCI_NUM Used with oci_fetch_all() and oci_fetch_array() to get results as an enumerated array.
OCI_RETURN_LOBS Used with oci_fetch_array() to get the data value of the LOB instead of the descriptor.
OCI_RETURN_NULLS Used with oci_fetch_array() to get empty array elements if the row items value is NULL.
OCI_SEEK_CUR Used with OCI-Lob::seek to set the seek position.
OCI_SEEK_END Used with OCI-Lob::seek to set the seek position.
OCI_SEEK_SET Used with OCI-Lob::seek to set the seek position.
OCI_SYSDATE Obsolete.
OCI_SYSDBA Used with oci_connect() to connect with the SYSDBA privilege. The php.ini setting oci8.privileged_connect should be enabled to use this.
OCI_SYSOPER Used with oci_connect() to connect with the SYSOPER privilege. The php.ini setting oci8.privileged_connect should be enabled to use this.
OCI_TEMP_BLOB Used with OCI-Lob::writeTemporary to indicate that a temporary BLOB should be created.
OCI_TEMP_CLOB Used with OCI-Lob::writeTemporary to indicate that a temporary CLOB should be created.
