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

mysqli_stmt::$sqlstate - Returns SQLSTATE error from previous statement operation

       Object oriented style

SYNOPSIS

       string$mysqli_stmt->sqlstate ()

DESCRIPTION

       Procedural style
       string mysqli_stmt_sqlstate (mysqli_stmt  $stmt)

	Returns  a  string  containing the SQLSTATE error code for the most recently invoked prepared statement function that can succeed or fail.
       The error code consists of five characters.  '00000' means no error. The values are specified by ANSI SQL and ODBC. For a list of  possible
       values, see http://dev.mysql.com/doc/mysql/en/error-handling.html.

PARAMETERS

	      o $
		stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).

RETURN VALUES

	Returns  a  string  containing	the  SQLSTATE error code for the last error. The error code consists of five characters.  '00000' means no
       error.

NOTES

       Note

	       Note that not all MySQL errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Open a connection */
	      $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $mysqli->query("CREATE TABLE myCountry LIKE Country");
	      $mysqli->query("INSERT INTO myCountry SELECT * FROM Country");

	      $query = "SELECT Name, Code FROM myCountry ORDER BY Name";
	      if ($stmt = $mysqli->prepare($query)) {

		  /* drop table */
		  $mysqli->query("DROP TABLE myCountry");

		  /* execute query */
		  $stmt->execute();

		  printf("Error: %s.
", $stmt->sqlstate);

		  /* close statement */
		  $stmt->close();
	      }

	      /* close connection */
	      $mysqli->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Open a connection */
	      $link = mysqli_connect("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      mysqli_query($link, "CREATE TABLE myCountry LIKE Country");
	      mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");

	      $query = "SELECT Name, Code FROM myCountry ORDER BY Name";
	      if ($stmt = mysqli_prepare($link, $query)) {

		  /* drop table */
		  mysqli_query($link, "DROP TABLE myCountry");

		  /* execute query */
		  mysqli_stmt_execute($stmt);

		  printf("Error: %s.
", mysqli_stmt_sqlstate($stmt));

		  /* close statement */
		  mysqli_stmt_close($stmt);
	      }

	      /* close connection */
	      mysqli_close($link);
	      ?>

	      The above examples will output:

	      Error: 42S02.
