db2_pconnect Returns a persistent connection to a database &reftitle.description; resourcedb2_pconnect stringdatabase stringusername stringpassword arrayoptions Returns a persistent connection to an IBM DB2 Universal Database, IBM Cloudscape, or Apache Derby database. For more information on persistent connections, refer to . Calling db2_close on a persistent connection always returns &true;, but the underlying DB2 client connection remains open and waiting to serve the next matching db2_pconnect request. &reftitle.parameters; database The database alias in the DB2 client catalog. username The username with which you are connecting to the database. password The password with which you are connecting to the database. options An associative array of connection options that affect the behavior of the connection, where valid array keys include: autocommit Passing the DB2_AUTOCOMMIT_ON value turns autocommit on for this connection handle. Passing the DB2_AUTOCOMMIT_OFF value turns autocommit off for this connection handle. DB2_ATTR_CASE Passing the DB2_CASE_NATURAL value specifies that column names are returned in natural case. Passing the DB2_CASE_LOWER value specifies that column names are returned in lower case. Passing the DB2_CASE_UPPER value specifies that column names are returned in upper case. CURSOR Passing the DB2_FORWARD_ONLY value specifies a forward-only cursor for a statement resource. This is the default cursor type and is supported on all database servers. Passing the DB2_SCROLLABLE value specifies a scrollable cursor for a statement resource. This mode enables random access to rows in a result set, but currently is supported only by IBM DB2 Universal Database. &reftitle.returnvalues; Returns a connection handle resource if the connection attempt is successful. db2_pconnect tries to reuse an existing connection resource that exactly matches the database, username, and password parameters. If the connection attempt fails, db2_pconnect returns &false;. &reftitle.examples; In the following example, the first call to db2_pconnect returns a new persistent connection resource. The second call to db2_pconnect returns a persistent connection resource that simply reuses the first persistent connection resource. ]]> &example.outputs; &reftitle.seealso; db2_connect
