How can I count the number of rows returned by a MySQL Query?

Is there an easier way of doing this besides loading the data into a DataTable and using Rows.Count or using a MySqlDataR开发者_高级运维eader and iterating through all the resulted rows?

---

if you cant change the query easily

SELECT COUNT(*) FROM (<your complete query here>)

---

You can execute a query like:

SELECT COUNT(*) FROM MyTable;

---

You can use the MySQL informational function FOUND_ROWS. Just run it immediately after your SELECT query. Like this:

SELECT FOUND_ROWS()

---

Exec an

select count(*) from MyTable WHERE <clause>

and get the result with ExecuteScalar()
