| 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(). |

         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. |

           Used with oci_fetch_array() to get empty
           array elements if the row items value is null.

| 常量 | 描述 | 
|---|---|
    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. |
