odbc_pconnect

(PHP 3>= 3.0.6, PHP 4 , PHP 5)

odbc_pconnect -- Open a persistent database connection

Description

resource odbc_pconnect ( string dsn, string user, string password [, int cursor_type])

Returns an ODBC connection id or 0 (FALSE) on error. This function is much like odbc_connect(), except that the connection is not really closed when the script has finished. Future requests for a connection with the same dsn, user, password combination (via odbc_connect() and odbc_pconnect()) can reuse the persistent connection.

注: Persistent connections have no effect if PHP is used as a CGI program.

For information about the optional cursor_type parameter see the odbc_connect() function. For more information on persistent connections, refer to the PHP FAQ.

The following constants are defined for cursortype:

 -
SQL_CUR_USE_IF_NEEDED 

 - SQL_CUR_USE_ODBC 

 - SQL_CUR_USE_DRIVER


 - SQL_CUR_DEFAULT 



With some ODBC drivers, executing a
complex stored procedure may fail with an error similar to: "Cannot
open a cursor on a stored procedure that has anything other than a single
select statement in it". Using SQL_CUR_USE_ODBC may avoid that error.
Also, some drivers don't support the optional row_number parameter in
odbc_fetch_row(). SQL_CUR_USE_ODBC might help in that case, too.
