I am using SQLite C# library and as per my requirement, before going to add I am retreving the rowid of that table. It is working fine but hetting error when table is empty. Once we add any data(a row) then it’s working fine .

        mDbCon  = GetConnection();
        SQLiteCommand cmd = mDbCon.CreateCommand();
        cmd.CommandText = " SELECT MAX(rowid) FROM " + “MYTABLE”;
        cmd.CommandType = CommandType.Text;
        mDbCon.Open();
        SQLiteDataReader sqReader = cmd.ExecuteReader();
        while (sqReader.Read())
        {
            if ( sqReader.IsDBNull(0) )
            {
                max = (Int32)sqReader.GetInt32(0);
            }
        }
        mDbCon.Close();

It’s throwing exception when table “MYTABLE” don’t have any data.
