SQL数据库 查询 SQL出错的解决方法是给子查询加别名,如下:String sqlstr=\"select top 15*from(select*from news order by ID desc)AS A where kind='yes' and ID not in(select top\"+v+\"ID from(select*from news order by ID desc)AS B where kind='yes');没有降序排列的原因是将查询条件放置在了带有order by子句的子查询外面,结果又重新排序了,只需改为:String sqlstr=\"select top 15*from(select*from news where kind='yes' order by ID desc)AS A and ID not in(select top\"+v+\"ID from(select*from news where kind='yes' order by ID desc)AS B);
sql数据库查询 select*from tab where isnull(type,0)in(0,1,2)
SQL数据库查询 public string Str(){这里面写查询的sql语句,c#查询语句等然后取值,例如你前面用的是dataset,则:DataSet dataset=new DataSet();string value=dataset.table[0].rows[0]['列名'].toString();return value;}然后在页面直接将这个值赋值就是,例如:string returnValue=Str();
