DB2_CONN_ERROR(3)							 1							 DB2_CONN_ERROR(3)

db2_conn_error - Returns a string containing the SQLSTATE returned by the last connection attempt

SYNOPSIS

       string db2_conn_error ([resource  $connection])

DESCRIPTION

       db2_conn_error(3)  returns  an  SQLSTATE  value representing the reason the last attempt to connect to a database failed. As db2_connect(3)
       returns FALSE in the event of a failed connection attempt, you do not pass any parameters to db2_conn_error(3)  to  retrieve  the  SQLSTATE
       value.

	If,  however, the connection was successful but becomes invalid over time, you can pass the $connection parameter to retrieve the SQLSTATE
       value for a specific connection.

	To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line  Processor  prompt:  db2  '?	$sqlstate-
       value'. You can also call db2_conn_errormsg(3) to retrieve an explicit error message and the associated SQLCODE value.

PARAMETERS

	      o $connection
		- A connection resource associated with a connection that initially succeeded, but which over time became invalid.

RETURN VALUES

	Returns  the  SQLSTATE	value resulting from a failed connection attempt. Returns an empty string if there is no error associated with the
       last connection attempt.

EXAMPLES

       Example #1

	      Retrieving an SQLSTATE value for a failed connection attempt

	       The following example demonstrates how to return an SQLSTATE value after deliberately passing invalid parameters to db2_connect(3).

	      <?php
	      $conn = db2_connect('badname', 'baduser', 'badpassword');
	      if (!$conn) {
		  print "SQLSTATE value: " . db2_conn_error();
	      }
	      ?>

	      The above example will output:

	      SQLSTATE value: 08001

DB2_AUTOCOMMIT(3)							 1							 DB2_AUTOCOMMIT(3)

db2_autocommit - Returns or sets the AUTOCOMMIT state for a database connection

SYNOPSIS

       mixed db2_autocommit (resource  $connection, [bool  $value])

DESCRIPTION

	Sets or gets the AUTOCOMMIT behavior of the specified connection resource.

PARAMETERS

	      o $connection
		- A valid database connection resource variable as returned from db2_connect(3) or db2_pconnect(3).

	      o $value
		- One of the following constants:

		     o DB2_AUTOCOMMIT_OFF - Turns AUTOCOMMIT off.

		     o DB2_AUTOCOMMIT_ON - Turns AUTOCOMMIT on.

RETURN VALUES

	When db2_autocommit(3) receives only the $connection parameter, it returns the current state of AUTOCOMMIT for the requested connection as
       an integer value. A value of 0 indicates that AUTOCOMMIT is off, while a value of 1 indicates that AUTOCOMMIT is on.

	When db2_autocommit(3) receives both the $connection parameter and $autocommit parameter, it attempts to set the AUTOCOMMIT state  of  the
       requested connection to the corresponding state. Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Retrieving the AUTOCOMMIT value for a connection

	       In the following example, a connection which has been created with AUTOCOMMIT turned off is tested with the db2_autocommit(3) func-
	      tion.

	      <?php
	      $options = array('autocommit' => DB2_AUTOCOMMIT_OFF);
	      $conn = db2_connect($database, $user, $password, $options);
	      $ac = db2_autocommit($conn);
	      if ($ac == 0) {
		  print "$ac -- AUTOCOMMIT is off.";
	      } else {
		  print "$ac -- AUTOCOMMIT is on.";
	      }
	      ?>

	      The above example will output:

	      0 -- AUTOCOMMIT is off.

       Example #2

	      Setting the AUTOCOMMIT value for a connection

	       In the following example, a connection which was initially created with AUTOCOMMIT turned off has  its  behavior  changed  to  turn
	      AUTOCOMMIT on.

	      <?php
	      $options = array('autocommit' => DB2_AUTOCOMMIT_OFF);
	      $conn = db2_connect($database, $user, $password, $options);

	      // Turn AUTOCOMMIT on
	      $rc = db2_autocommit($conn, DB2_AUTOCOMMIT_ON);
	      if ($rc) {
		  print "Turning AUTOCOMMIT on succeeded.
";
	      }

	      // Check AUTOCOMMIT state
	      $ac = db2_autocommit($conn);
	      if ($ac == 0) {
		  print "$ac -- AUTOCOMMIT is off.";
	      } else {
		  print "$ac -- AUTOCOMMIT is on.";
	      }
	      ?>

	      The above example will output:

	      Turning AUTOCOMMIT on succeeded.
	      1 -- AUTOCOMMIT is on.
