sql查詢和

㈠ sql語句查詢某欄位的數據總和，並列出表中的所有記錄。

1、首先，創建一個測試表，相關代碼如下，進入下一步。

㈡ SQL如何將幾條語句查詢結果求和

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怎麼講查詢結果求和如圖

你好，很高興回答你的問題。最簡單的就是把你的這個查詢當做一個子查詢來求和。
select sum(總計) from (你的查詢)
如果有幫助到你，請點擊採納。

㈣ sql對查詢結果求和

作為兩個子查詢再查一次就行了
select isnull(t1.[詳情],t2.[詳情]) AS [詳情],
ISNULL(t1.[次數], 0) AS [贈_次數],
ISNULL(t2.[次數], 0) AS [送_次數],
ISNULL(t1.[次數], 0) + ISNULL(t2.[次數], 0) AS [總次數]
FROM
(....) AS t1
FULL OUTER JOIN
(....) AS t2
ON t1.[詳情]=t2.[詳情]

㈤ sql求和查詢

selectsum(d1)asd1sum,sum(d2)asd2sum,sum(d3)asd3sumfromyour_table_namewherenamein('張三','李四')andtime='20180919';
