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().
