SQL查询中,"SELECT 学号,姓名,性别 FROM 学生 W...

string sql=string.Format("select * from student where date='{0}' ",DateTime.Parse("2014-08-16 13:00:00")); 改成上面语句试试先,如果上面语句运行不报错说明是你的txtDate.Text不是时间格式的字符串

String s = "sf"; String sql = "select * from stu where stuName like '%"+s+"%'";

SELECT * FROM ABC W WHERE Creatdatetime=(SELECT min(Creatdatetime) FROM ABC WHERE ID=W.ID AND RESULT=W.RESULT)

1.select * from works where not exists(select 1 from data_1 where works.id=data_1.w_id) 2..select * from works where exists(select 1 from data_1 where works.id=data_1.w_id)

是这个意思吗? SUM(CASE WHEN W.TypeID = 999 AND (SUM(CASE WHEN W.TypeID = 999 AND BDate='2014-04-02' THEN BValue ELSE 0 end) as EndingBalance)='2014-04-02' THEN BValue ELSE 0 end) as EndingBalance请详细描述一下需求

你是通过鼠标右键单击表,选择打开的吧?默认是1000行,你把生成的语句中的TOP 1000删除即可 /****** Script for SelectTopNRows command from SSMS ******/ SELECT TOP 1000 [Cno] ,[Cname] ,[Ccredit] ,[Semester] FROM [Students].[dbo].[Cou...

from e191_sporter x --x是e191_sporter的临时表名字, from e191_sporter w,e191_grade y --w y也是 from e191_grade z 这些可以这样写:from e191_grade as z (其中一个作用就是简化写法) y.pno 其实就是e191_grade.pno

--查询一: select w.id,w.name,w.format,w.type from works w where not exists ( select 1 from data_1 d where exists ( select 1 from user u where u.name='NO02' and u.id=d.u_id ) and w.id=d.w_id ); --查询二: seelct d.id,w.name,d.A,d...

select W.订单编号,sum(W.数据1) AS Y1,sum(W.数据2) AS Y2,,sum(W.数据3) AS Y3 from 表A AS S ,表B AS W where S.日期

这两个东西看起来应该是自定义的两个函数,比如sql_r的作用可能是执行括号里面的select语句,得到的结果集合赋值给rs
