How about using pdo_raise_impl_error() for SQLSTATE 22001?

hmm, should it use 22001 regardless of error mode, or should it use 22001 for exception and 01004 otherwise?

Since 01004 is a warning that occurs when read data is discarded for instance, when the buffer is too small, I believe that in every case, 22001 is the appropriate choice.

edit:
Since this distinction is made in systems like DB2 and ODBC, 01004 is generally considered to be related to fetch operations.

return NULL;
