odbc_longreadlen

Handling of LONG columns

&reftitle.description; `bool` `odbc_longreadlen` `resource` `statement` `int` `length`

Controls handling of `LONG`, `LONGVARCHAR` and `LONGVARBINARY` columns. The default length can be set using the uodbc.defaultlrl &php.ini; directive.

&reftitle.parameters;

`statement`

- The result identifier.

`length`

- 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 (i.e. printed) when retrieved with `odbc_result`.

&reftitle.returnvalues;

&return.success;

&reftitle.notes;

Handling of `LONGVARBINARY` columns is also affected by `odbc_binmode`.
