以前发布时,我错过了保存urn和org_ref的表b。我有三张桌子。表a,b和c,其中我必须根据表a中的URN键更新表c的“总Emp”列。表B没有URN列,但是它具有Org_ref,因此要连接表a和表c,我们需要在a.urn = b.urn上连接表b。我编写了一个查询来遍历记录并进行插入或更新,但是它不起作用并且不会更新。只需在表b中插入空白“员工总数”即可。
表
|urn |total employee
|333 |25
|123 |26
|21 |2
|11 |23
表B
|urn |org_ref
|333 |1234
|123 |343
|21 |2
|11 |23
表C
org_ref total employe
1234 0 --should update from table a
343 0 --should update from table a
--add record from table a org_ref 21
--add record from table a org_ref 11
这是我的剧本
Create table #orgs(
iorgrowid int identity (1,1),
ORG_REF varchar(255),
Total_Leader int,
urn int
)
insert into #orgs
select ORG.organisation_ref,s.[TOTAL_LEADERSHIP_ROLE],s.urn
from DiTestDatabase.dbo.organisation org
JOIN DataConversion.dbo.School_plus_download_NI s on org.total_headcount=s.urn
DECLARE

END
SELECT

FROM #orgs
WHERE iorgRowId = @iNextcodeRowId
set @counter = 0
set @orgnamecount=0
set @add1count=0
--Start the main processing loop.
WHILE @iCodeLoopControl = 1

SELECT @iNextCodeRowId = NULL
--Get the next iRowId.
SELECT @iNextcodeRowId = MIN(iorgrowId)
FROM #orgs
WHERE iorgrowId > @iCurrentcodeRowId
--Did we get a valid next row id?
IF ISNULL(@iNextCodeRowId,0) = 0
BEGIN
BREAK
END
SELECT @iCurrentcodeRowId = iorgrowId,
@ORGREF=ORG_REF,
@Ly_employees=Total_Leader
FROM #orgs
WHERE iorgRowId = @iNextcodeRowId
END
DROP TABLE #orgs
RETURN
解决方案:-由于我在表a和c之间没有任何共同之处,因此我不得不寻求表b的帮助,其中a和b之间唯一的共同之处是URN列,而b和c之间唯一的共同之处是Org_ref。我对更新进行了更改
SET LY_EMPLOYEES= (SELECT SP.TOTAL_LEADERSHIP_ROLE
FROM DataConversion.dbo.School_plus_download_NI SP
JOIN ORGANISATION ORG ON ORG.TOTAL_HEADCOUNT=SP.URN
JOIN ORG_ACCOUNT OA ON OA.ORGANISATION_REF=ORG.ORGANISATION_REF
WHERE sp.URN = @urn) --@ORGREF)
FROM ORG_ACCOUNT WHERE ORGANISATION_REF=@ORG_REF
解决了这个问题。

这有帮助吗??
CREATE TABLE #a(urn bigint, total_employe bigint)
CREATE TABLE #b(urn bigint,org_ref bigint)
CREATE TABLE #c(org_ref bigint,total_employe bigint)
INSERT INTO #a
SELECT 333,25 Union ALL
SELECT 123,26 Union ALL
SELECT 21,2 Union ALL
SELECT 11,23
INSERT INTO #b
SELECT 333,1234 Union ALL
SELECT 123,343 Union ALL
SELECT 21,2 Union ALL
SELECT 11,23
INSERT INTO #c
SELECT 1234,0 Union ALL
SELECT 343,0
;with cte
AS
(
SELECT b.org_ref,a.total_employe from #a a

MERGE INTO #c c

UPDATE
SET c.total_employe=cte.total_employe
WHEN NOT MATCHED THEN
INSERT(org_ref,total_employe)
VALUES(org_ref,total_employe);
SELECT * FROM #c
DROP TABLE #a

请勿使用while循环或游标进行简单的upsert操作!您会在网络上到处发现它适得其反!
我将以表a / b的简单形式回答:
-- First, update the ones that exist
update alias_b -- Note that you NEED an alias to update using join
set [total employee]=a.[total employee]
from a
inner join b alias_b on a.org_ref=alias_b.org_ref
-- Then, insert the ones that don't
insert b
select (the columns you want)
from a
where not exists (select 1 from b where a.org_ref=b.org_ref)
答案 2 :(得分:0)
--UPDATE
UPDATE B SET B.TOTAL_LEADER = A.TOTAL_LEADER FROM TABLEA A INNER JOIN TABLEB B ON
A.ORG_REF = B.ORG_REF
--INSERT
INSERT INTO TABLEB(ORG_REF,URN,TOTAL_LEADER)
SELECT A.ORG_REF,A.URN,A.TOTAL_LEADER FROM TABLEA A LEFT OUTER JOIN TABLEB B ON
A.ORG_REF = B.ORG_REF WHERE B.ORG_REF IS NULL
我认为您正在寻找这个。

SELECT INTO怎么样?像这样:
SELECT b.org_ref, a.totalemployee INTO c FROM a LEFT JOIN b ON (a.urn = b.urn)
