<p class="para">
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 specific to warnings
and errors that derive from the implementation of PDO (or perhaps ODBC,
if you're using the ODBC driver) itself. The subclass value '000' in any
class indicates that there is no subclass for that SQLSTATE.

<p class="para">
<span class="function"><strong>PDO::errorCode()</strong></span> only retrieves error codes for operations
performed directly on the database handle. If you create a PDOStatement
object through <span class="function"><a href="pdo.prepare.html" class="function">PDO::prepare()</a></span> or
<span class="function"><a href="pdo.query.html" class="function">PDO::query()</a></span> and invoke an error on the statement
handle, <span class="function"><strong>PDO::errorCode()</strong></span> will not reflect that error.
You must call <span class="function"><a href="pdostatement.errorcode.html" class="function">PDOStatement::errorCode()</a></span> to return the error
code for an operation performed on a particular statement handle.
</p>
<p class="para">
Returns <strong><code>NULL</code></strong> if no operation has been run on the database handle.
