I am trying to write a generic method where I can send a SQL statement as a parameter and have the statement execute in my Access Database. Have written one that works when all I'm doing is getting information from the database, but I can't seem to get one working that puts information into the database.
SQL = Insert Into [Category] (CategoryDescription) values('Pizza')
And I am getting a "Operation must use an updateable query" error

What I have tried:

public void ExecuteAction(string SQL)
        {
            OpenDatabase();
            OleDbCommand myAccessCommand = new OleDbCommand(SQL, Conn);
            myAccessCommand.ExecuteNonQuery();
            CloseDatabase();
        }

But this doesn't work.
