MySQL在C＃中查询丢失的记录

Question

我正在使用MySql中的MySql.Data dll并尝试执行查询以将数据从MySQL表传输到MSSQL表。我正在运行以下代码：

MySqlCommand catCmd = new MySqlCommand();

catCmd.CommandType = System.Data.CommandType.Text;
catCmd.Connection = connection;

//Add categories to static class
catCmd.CommandText = "SELECT c.categories_id, categories_image, parent_id, categories_status, categories_name, categories_description FROM categories c JOIN categories_description d ON c.categories_id = d.categories_id ORDER BY categories_status";
MySqlDataReader catReader = catCmd.ExecuteReader();
while (catReader.Read())
{
    try
    {
        tables.categories.Add(new category(0, catReader.GetInt32(0), catReader.GetString(1), catReader.GetInt32(2), catReader.GetInt32(3), catReader.GetString(4), catReader.GetString(5)));
    }
    catch
    {
        tables.categories.Add(new category(0, catReader.GetInt32(0), "", catReader.GetInt32(2), catReader.GetInt32(3), catReader.GetString(4), catReader.GetString(5)));
    }
}
reader.Close();

当我在同一个数据库的MySQL查询浏览器中直接运行此查询时，它返回115条记录。但是在程序中，使用上面的代码。它返回106行。没什么不同的，我很沮丧。有线索吗？

更新

这就是我测试返回记录的数量：

这是Mysql查询浏览器中的相同查询

请尝试一些事情链接这个。

  public DataTable DataReader(string query)
    {
        DataTable mysqlDataTable = new DataTable();
        try
        {
            ConnectToMysql();// Add Mysql Connection Here. 
            MySqlDataAdapter readerAdapter = new MySqlDataAdapter(query, MysqlDBConnection);//MySqlConnection MysqlDBConnection;
            readerAdapter.Fill(mysqlDataTable);
            readerAdapter.Dispose();
            MysqlDBConnection.Close();
            MysqlDBConnection.Dispose();
            return mysqlDataTable;
        }
        catch
        {
            throw;
        }
    }
