sql查询和

㈠ sql语句查询某字段的数据总和，并列出表中的所有记录。

1、首先，创建一个测试表，相关代码如下，进入下一步。

㈡ SQL如何将几条语句查询结果求和

select一型,。。。,五型,一型+...+五型as和
from(
selectISNULL(sum(casewhentotalweightlimit=17000andoverloadweight>170thenvehcountelse0end),0)一型,ISNULL(sum(casewhentotalweightlimit=25000andoverloadweight>250thenvehcountelse0end),0)二型,ISNULL(sum(casewhentotalweightlimit=35000andoverloadweight>350thenvehcountelse0end),0)三型,ISNULL(sum(casewhentotalweightlimit=43000andoverloadweight>430thenvehcountelse0end),0)四型,ISNULL(sum(casewhentotalweightlimit=49000andoverloadweight>490thenvehcountelse0end),0)五型'20171101'and'20171130'andexvehicleflag=2
)abc

㈢ sql怎么讲查询结果求和如图

你好，很高兴回答你的问题。最简单的就是把你的这个查询当做一个子查询来求和。
select sum(总计) from (你的查询)
如果有帮助到你，请点击采纳。

㈣ sql对查询结果求和

作为两个子查询再查一次就行了
select isnull(t1.[详情],t2.[详情]) AS [详情],
ISNULL(t1.[次数], 0) AS [赠_次数],
ISNULL(t2.[次数], 0) AS [送_次数],
ISNULL(t1.[次数], 0) + ISNULL(t2.[次数], 0) AS [总次数]
FROM
(....) AS t1
FULL OUTER JOIN
(....) AS t2
ON t1.[详情]=t2.[详情]

㈤ sql求和查询

selectsum(d1)asd1sum,sum(d2)asd2sum,sum(d3)asd3sumfromyour_table_namewherenamein('张三','李四')andtime='20180919';
