The optional fourth parameter sets the type of cursor to be used
for this connection. This parameter is not normally needed, but
can be useful for working around problems with some ODBC drivers.
</P
><P
> With some ODBC drivers, executing a complex stored procedure may
fail with an error similar to: "Cannot open a cursor on a stored
procedure that has anything other than a single select statement
in it". Using SQL_CUR_USE_ODBC may avoid that error. Also, some
drivers don't support the optional row_number parameter in
<A
HREF="function.odbc-fetch-row.html"
><B
CLASS="function"
>odbc_fetch_row()</B

>. SQL_CUR_USE_ODBC might help
in that case, too.
