odbc_fetch_row - Fetch a row

SYNOPSIS
bool odbc_fetch_row (resource $result_id, [int $row_number]) DESCRIPTION
Fetches a row of the data that was returned by odbc_do(3) or odbc_exec(3). After odbc_fetch_row(3) is called, the fields of that row can be accessed with odbc_result(3). PARAMETERS
o $result_id - The result identifier. o $row_number - If $row_number is not specified, odbc_fetch_row(3) will try to fetch the next row in the result set. Calls to odbc_fetch_row(3) with and without $row_number can be mixed. To step through the result more than once, you can call odbc_fetch_row(3) with $row_number 1, and then continue doing odbc_fetch_row(3) without $row_number to review the result. If a driver doesn't support fetching rows by number, the $row_number parameter is ignored. RETURN VALUES
Returns TRUE if there was a row, FALSE otherwise. PHP Documentation Group ODBC_FETCH_ROW(3)
