odbc_longreadlen
Handling of LONG columns
(PHP 4, PHP 5)
bool odbc_longreadlen ( resource result_id, int length )
(ODBC SQL types affected: LONG, LONGVARBINARY) The number of bytes returned to PHP is controlled by the parameter length. If it is set to 0, Long column data is passed through to the client.
Note:
Handling of LONGVARBINARY columns is also affected by odbc_binmode().
