cubrid_num_rows — Get the number of rows in the result set
Description
$result
)The cubrid_num_rows() function is used to get the number of rows from the query result. You can use it only when the query executed is a select statement. When you want to know such value for INSERT, UPDATE, or DELETE query, you have to use the cubrid_affected_rows() function.
Note: The cubrid_num_rows() function can only be used for synchronous query; it returns 0 when it is used for asynchronous query.
