If odbc_fetch_row() was successful (there was a row), TRUE is returned. If there are no more rows, FALSE is returned.
odbc_fetch_row() fetches a row of the data that was returned by odbc_do() / odbc_exec(). After odbc_fetch_row() is called, the fields of that row can be accessed with odbc_result().
If row_number is not specified,
odbc_fetch_row() will try to fetch the next
row in the result set. Calls to
odbc_fetch_row() with and without
row_number can be mixed.
To step through the result more than once, you can call
odbc_fetch_row() with
row_number 1, and then continue doing
odbc_fetch_row() without
row_number to review the result. If a
driver doesn't support fetching rows by number, the
row_number parameter is ignored.
