Question

How to check if my table is empty from C#?

I have something like:

public MySqlConnection con;
public MySqlCommand cmd;

 con = new MySqlConnection(GetConnectionString());
 con.Open();
 cmd = new MySqlCommand("SELECT * FROM data;", con);

Or I don’t need to call SELECT statement?

Answer 1

You can use COUNT(*) with no WHERE close and see if exactly how many rows exist with the result.

Or you can do a SELECT (id) FROM tablename with no WHERE clause and if no rows are returned then the table is empty.
