mysqldataadapter不接受；在查询中

问题描述

嗨
我正在编写查询以生成运行时索引列，如下所示:

SET @rank = 0 ; SELECT @rank:=@rank+1 AS 否，unm=''abc''
用户的名字
当我复制&时查询运行正常将其粘贴到sqlyog编辑器(我正在使用mysql)
它显示正确的结果.
但是，当我用.NET代码编写相同的查询时，在下面的代码中，它显示错误.可能是'';''的becos

Hi
I am writing a query to generate a runtime index column as follows:

SET @rank = 0 ; SELECT @rank:=@rank+1 AS No,firstname from users where unm=''abc''

The query is running fine when I copy & paste it to sqlyog editor (I am using mysql)
It shows the correct results.
But when i written same query in .NET code and at the movement below code it showing error. It might be becos of '';''

Dataset ds = new Dataset()<br />
MySqlDataAdapter dAdap = new MySqlDataAdapter(SelectQuery, connection);<br />
dAdap.Fill(ds);

还有其他解决方案吗?

如果我想生成运行时索引列并将该列返回到数据集中，是否还有其他解决方案?

谢谢
