1、Select * From chuang_AgentInfo Where UserName='成都'  --在MySql工具里面查询有记录

2、以下代码查询上面语句，没有记录table.row.count为0
MySqlCommand thisCommand = new MySqlCommand();
thisCommand.CommandTimeout = 0;

// make sure connection is open
MySqlConnection con = new MySqlConnection(vStrConn);
try
{
    con.Open();
    thisCommand.Connection = con;
thisCommand.CommandText = SQL;

    MySqlDataAdapter thisAdapter = new MySqlDataAdapter();
    thisAdapter.SelectCommand = thisCommand;
    DataTable table = new DataTable();
    thisAdapter.Fill(table);
    return table;
}

3、以上代码查询 Select * From chuang_AgentInfo 有记录，可以查到。
