Question

I’m having a problem with Dim query As New MySqlCommand("Select count(*)....") I would like to take the variable query and do an If query <> 1 Then statement on it. Is this possible or is there a completely other way to go about this comparing the contents of a MySQL select statement. I’m rather new to Visual Basic.

Answer 1

The MySqlCommand type doesn’t return the results after construction, it just creates an object that can run queries. You must then execute the query:

Dim result as Integer
Using cn As New MySqlConnection("your connection string here"), _
      cmd As New MySqlCommand("Select count(*) ...", cn)

    cn.Open()
    result = CInt(cmd.ExecuteScalar())
End Using

Don’t forget to use query parameters rather than string concatenation to substitute data into your sql statements.
