I have a problem when I executed Select command in C# using ExecuteNonQuery() method; It always return -1; This means that no record returned by the selected statement, doesn’t it?

But when i open sql managment studio and run the same select statement; I found that it returned rows.

Please help me!

    You shouldn’t execute a SELECT with an ExecuteNonQuery(). It is called ExecuteNonQuery because you want something to execute that is not a query. A SELECT is a query. You want to ExecuteReader. If you want to do an UPDATE or DELETE, then you can do an ExecuteNonQuery() and that will show how many rows were affected.
