<function>PDO::errorInfo</function> returns an array of error information
|
|
about the last operation performed by this database handle. The array

consists of the following fields:

</para>
|

|
<para>
|
|
<function>PDO::errorInfo</function> only retrieves error information
|
|
for operations performed directly on the database handle. If you create
|
|
a PDOStatement object through <function>PDO::prepare</function> or
|
|
<function>PDO::query</function> and invoke an error on the statement
|
|
handle, <function>PDO::errorInfo</function> will insert an error code
|
|
of <literal>PDO_ERR_NONE</literal> into the first element of the returned
|
|
array. You must call <function>PDOStatement::errorInfo</function> to
|
|
return the error information for an operation performed on a particular
|
|
statement handle.
