|
|
Returns a SQLSTATE, a five-character alphanumeric identifier defined in
|
|
the ANSI SQL-92 standard. Briefly, an SQLSTATE consists of a
|
|
two-character class value followed by a three-character 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.
|
|
</para>
|
|
<para>
|
|
<function>PDO::errorCode</function> only retrieves error codes 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::errorCode</function> will not reflect that error.
|
|
You must call <function>PDOStatement::errorCode</function> to return the error
|
|
code for an operation performed on a particular statement handle.
