Select TABLE1.x_ID,SUM(TABLE1.x_sale) AS sumsalein FROM table1 WHERE (TABLE1.x_date BETWEEN '"&2009-12-01 &"' AND '"&2009-12-03&"') GROUP BY TABLE1.x_ID union select '总和',sum(table1.x_sale) as sumsalein from table1 where (TAB...

SQL:select * from A,B where A.cpID=B.cpID and A.cbID=B.cbID LINQ:var p = from t1 in a from t2 in b from t3 in c where t1.cpid equal t2.cpid and t1.cbid equal t3.cbid select new { t1, t2.cpid } linq 也能实现 sum、groupby 的效果...

一、 聚合函数: sql语言中一种特殊的函数:聚合函数,SUM, COUNT, MAX, MIN, AVG等。这些函数和其它函数的根本区别就是它们一般作用在多条记录上。 SELECT SUM(population) FROM COUNTRY 这里的SUM作用在所有返回记录的population字段上,结果就...

这个样子?sqlserver? update a set a.hour=c.hour from a inner join (select id,sum(isnull(hour,0)) hour from b group by id) c on a.id=c.id

select * from (SELECT b.CLIENTNO,b.CNAME,SUM(a.AMOUNT) TAMOUNT FROM PURCHASE a, CLIENT b where a.CLIENTNO=b.CLIENTNO GROUP BY a.CLIENTNO order by TAMOUNT) aa where rowNum=1

因为你前面已经用了聚合函数 如count/sum等,还有一些单独的字段,这样你就必须要把这些单独的字段group by。否则计算机没法计算你的聚合函数。 你的脚本写的有点乱,看不明白是要做什么。 例如,select a,b,c,count(*),sum(a) from table1 grou...

sum本身就是分组函数啦,所以不用

从B表里查询单位、cs的总数,按单位排序,并把结果保存到C表里
