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.
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 OCILob::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.
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 OCILob::seek to set the seek position.
OCI_SEEK_END	Used with OCILob::seek to set the seek position.
OCI_SEEK_SET	Used with OCILob::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 OCILob::writeTemporary to indicate that a temporary BLOB should be created.
OCI_TEMP_CLOB	Used with OCILob::writeTemporary to indicate that a temporary CLOB should be created.

OCI8 Bind and Define Types

Constant	Description

OCI_B_BLOB	Used with oci_bind_by_name() when binding BLOBs.
OCI_B_BOL	Used with oci_bind_by_name() to bind a PL/SQL BOOLEAN variable.
OCI_B_CFILEE	Used with oci_bind_by_name() when binding CFILEs.
OCI_B_CLOB	Used with oci_bind_by_name() when binding CLOBs.
OCI_B_CURSOR	Used with oci_bind_by_name() when binding cursors, previously allocated with oci_new_descriptor().
OCI_B_INT	Used with oci_bind_array_by_name() to bind arrays of INTEGER.
OCI_B_NTY	Used with oci_bind_by_name() when binding named data types.

OCI8 Descriptor Types

Constant	Description
OCI_DTYPE_FILE	This flag tells oci_new_descriptor() to initialize a new FILE descriptor.
OCI_DTYPE_LOB	This flag tells oci_new_descriptor() to initialize a new LOB descriptor.
OCI_DTYPE_ROWID	This flag tells oci_new_descriptor() to initialize a new ROWID descriptor.
OCI_D_FILE	The same as OCI_DTYPE_FILE.
OCI_D_LOB	The same as OCI_DTYPE_LOB.
OCI_D_ROWID	The same as OCI_DTYPE_ROWID.

OCI8 Transparent Application Failover (TAF) Constants

Sabitler	Açıklama
OCI_FO_ABORT (int)	Failover was unsuccessful and there is no option of retrying.
OCI_FO_BEGIN (int)	Failover has detected a lost connection and failover is starting.
OCI_FO_END (int)	Failover completed successfully.
OCI_FO_ERROR (int)	Failover was unsuccessful but it gives the application the opportunity to handle the error and return OCI_FO_RETRY to retry failover.
OCI_FO_NONE (int)	The user has not requested a failover type.
OCI_FO_REAUTH (int)	An Oracle user has been re-authenticated.
OCI_FO_RETRY (int)	The failover should be attempted again by Oracle. In case of an error while failing over to a new connection, TAF is able to retry the failover. Typically, the application code should sleep for a while before returning OCI_FO_RETRY.
OCI_FO_SELECT (int)	The user has requested SELECT failover as well. It allows users with open cursors to continue fetching from them after failure.
OCI_FO_SESSION (int)	The user has requested only session failover. For example, if a user's connection is lost, then a new session is automatically created for the user on the backup. This type of failover does not attempt to recover SELECTs.
OCI_FO_TXNAL (int)	The user has requested a transaction failover.
