DB2_CONN_ERRORMSG(3)							 1						      DB2_CONN_ERRORMSG(3)

db2_conn_errormsg - Returns the last connection error message and SQLCODE value

SYNOPSIS
       string db2_conn_errormsg ([resource  $connection])

DESCRIPTION
       db2_conn_errormsg(3)  returns  an  error  message and SQLCODE value representing the reason the last database connection attempt failed. As
       db2_connect(3) returns FALSE in the event of a failed connection attempt, do not pass any parameters to	db2_conn_errormsg(3)  to  retrieve
       the associated error message and SQLCODE value.

	If,  however,  the connection was successful but becomes invalid over time, you can pass the $connection parameter to retrieve the associ-
       ated error message and SQLCODE value for a specific connection.

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

RETURN VALUES
	Returns a string containing the error message and SQLCODE value resulting from a failed connection attempt. If there is no  error  associ-
       ated with the last connection attempt, db2_conn_errormsg(3) returns an empty string.

EXAMPLES
       Example #1

	      Retrieving the error message returned by a failed connection attempt

	       The  following  example demonstrates how to return an error message and SQLCODE value after deliberately passing invalid parameters
	      to db2_connect(3).

	      <?php
	      $conn = db2_connect('badname', 'baduser', 'badpassword');
	      if (!$conn) {
		  print db2_conn_errormsg();
	      }
	      ?>

	      The above example will output:

	      [IBM][CLI Driver] SQL1013N  The database alias name
	      or database name "BADNAME" could not be found.  SQLSTATE=42705
	       SQLCODE=-1013
