PDO
::errorCode - Fetch the SQLSTATE associated with the last operation on the database handle

SYNOPSIS

       public mixed PDO::errorCode (void  )

DESCRIPTION

RETURN VALUES

	Returns an SQLSTATE, a five characters alphanumeric identifier defined in the ANSI SQL-92 standard. Briefly, an SQLSTATE consists of a two
       characters class value followed by a three characters subclass value. A class value of 01 indicates a  warning  and  is	accompanied  by  a
       return  code  of  SQL_SUCCESS_WITH_INFO. Class values other than '01', except for the class 'IM', indicate an error. The class 'IM' is spe-
       cific to warnings and errors that derive from the implementation of PDO (or perhaps ODBC, if you're using the ODBC driver) itself. The sub-
       class value '000' in any class indicates that there is no subclass for that SQLSTATE.

       PDO.errorCode(3)  only  retrieves error codes for operations performed directly on the database handle. If you create a PDOStatement object
       through PDO.prepare(3) or PDO.query(3) and invoke an error on the statement handle, PDO.errorCode(3) will not reflect that error. You  must
       call PDOStatement.errorCode(3) to return the error code for an operation performed on a particular statement handle.

	Returns NULL if no operation has been run on the database handle.

EXAMPLES

       Example #1

	      Retrieving an SQLSTATE code

	      <?php
	      /* Provoke an error -- the BONES table does not exist */
	      $dbh->exec("INSERT INTO bones(skull) VALUES ('lucy')");

	      echo "
PDO::errorCode(): ", $dbh->errorCode();
	      ?>

	      The above example will output:

	      PDO::errorCode(): 42S02
