MERGE tbl_target t
USING tbl_source s
ON t.itemnum = s.itemnum
WHEN NOT MATCHED
INSERT (itemnum, minqty, maxqty, parent)
VALUES (s.itemnum,0,99,10),(s.itemnum,0,99,80);
I'm trying to Insert two rows on the target table if an item does not exist on target but does exist on the source. Everytime I try SQL server gives an error on the ',' between the VALUES.
A MERGE statement must be terminated by a semi-colon (;)
Is it possible to do multi-row inserts in a MERGE statement?
It is possible by tweaking the USING clause to return multiple rows per tbl_source.itemnum value:
MERGE tbl_target t
USING (
select s.itemnum,
0 as minqty,
99 as maxqty,
p.parent
from tbl_source s
cross join (
select 10 as parent
union all
select 80 as parent) p
) s
ON t.itemnum = s.itemnum
WHEN NOT MATCHED THEN
INSERT (itemnum, minqty, maxqty, parent)
VALUES (s.itemnum,s.minqty,s.maxqty,s.parent);
What I understand from msdn is that you can only insert a row for each non matching record. Do you need to use Merge? If not the following will work
WITH CTE (Sitemnum)
AS
(
SELECT s.itemnum
FROM tbl_source s
LEFT JOIN tbl_target t ON (s.itemnum = t.itemnum)
WHERE t.itemnum IS NULL
)
INSERT tbl_target
SELECT Sitemnum,0,99,10
FROM CTE
UNION
SELECT Sitemnum,0,99,80
FROM CTE

I'm working in SQL Server 2016. Confusing problem with SQL issue. I have a TEMP table that contains unique rows. I have to insert 5 PRODUCTID values for each row each row based on another column value, AgentNo, in this temp table. The PRODUCTID value, there are 5 of them, comes from another table but there is no relationship between the tables. So my question is how do I insert a row for each ProductID into this temp table for each unique row that is currently in the temp table.
Here is a pic of the TEMP table that requires 5 rows for each:
Here is a pic of what I'm needing to come away with:
Here is my SQL code for both TEMP tables:
IF OBJECT_ID('tempdb..#tempTarget') IS NOT NULL DROP TABLE #tempTarget
SELECT 0 as ProductID, 1 as [Status], a.AgentNo, u.UserID, u.[Password], 'N' as AdminID, tel.LocationSysID --, tel.OwnerID, tel.LocationName, a.OwnerSysID, a.AgentName
INTO #tempTarget
FROM dbo.TEST_EvalLocations tel
INNER JOIN dbo.AGT_Agent a
ON tel.LocationName = a.AgentName
INNER JOIN dbo.IW_User u
ON a.AgentNo = u.UserID
WHERE tel.OwnerID = 13313
AND tel.LocationSysID <> 15434;
SELECT * FROM #tempTarget WHERE LocationSysID NOT IN (15425, 15434);
GO
-- Create source table
IF OBJECT_ID('tempdb..#tempSource') IS NOT NULL DROP TABLE #tempSource
SELECT DISTINCT lpr.ProductID
INTO #tempSource
FROM dbo.Eval_LocationProductRelationship lpr
WHERE lpr.ProductID IN (16, 15, 13, 14, 12) --BETWEEN 15435 AND 15595
Sorry I could not get this into a DDL file as these are TEMP tabless. Any help/direction would be appreciated. Thanks.
CROSS JOIN will be the best solution for your case.
If you only want 5 rows for each data in First table means, simply use the below cross join query.
SELECT B.ProductID,
A.[Status],
A.AgentNo,
A.UserID,
A.[Password] AS Value,
A.AdminID,
A.LocationSysID
FROM #tempTarget A
CROSS JOIN tempSource B
If you want additional row with 0, then you have to insert a 0 into your second temp table and use the same query.
INSERT INTO #tempSource SELECT 0
If i understand correctly following is the scenario,
One Temp table has all the content.
select * from #withoutProducts
product table
select * from #products
Then following is the query your are looking for
select a.ProductID,[Status],AgentNo,UserID,[value]
from #products a cross join #withoutProducts b
order by AgentNO,a.productID
Scenario:
I have a simplified version of a result set obtained from a series of complex joins. I have placed the result set in a temporary table. The result set consists of records of activity/activities in a day.
I need to join the 2 rows (merge activities of a day into a single row) with similar dates so that the resulting result set would be
I am trying to make this work
Merge #temp as target
using #temp as source
on (target.Date = source.Date) and target.Writing is NULL
when matched then
update set target.Writing = source.Writing;
but I'm running into this error:
The MERGE statement attempted to UPDATE or DELETE the same row more
than once. This happens when a target row matches more than one source
row. A MERGE statement cannot UPDATE/DELETE the same row of the target
table multiple times. Refine the ON clause to ensure a target row
matches at most one source row, or use the GROUP BY clause to group
the source rows.
What code modifications can you suggest?
This should do it:
SELECT dfl.mydate, dfl.firststart, dfl.lastend, fa.ActivityA, sa.ActivityB
FROM
(select s.mydate, firststart, lastend FROM
(SELECT mydate, MIN(starttime) as firststart from target GROUP by mydate) s
iNNER JOIN
(SELECT mydate, MAX(EndTime) as lastend from target GROUP by mydate) e
ON s.mydate = e.mydate) AS dfl
INNER JOIN
target fa on dfl.mydate = fa.mydate and dfl.firststart = fa.starttime
INNER JOIN
target sa on dfl.mydate = sa.mydate and dfl.lastend = sa.EndTime
Please note for my test I have called my table target and the columns: mydate, starttime, endtime, activitya and activityb.
No need to merge, a (relatively) simple select yields the results you want.

PS It helps when using time data to use a 24 hour clock. I have assumed by 5:00 you really meant 17:00
You don't need MERGE statement.
DECLARE #Test TABLE ([Id] int, [Date] nvarchar(10), [TimeIn] nvarchar(10), [TimeOut] nvarchar(10), [Reading] nvarchar(10), [Writeing] nvarchar(10))
INSERT INTO #Test
VALUES
(1,'08-01','8:00','5:00','Y',NULL),
(2,'08-02','8:00','5:00',NULL,'Y'),
(3,'08-02','5:00','12:00',NULL,'Y'),
(4,'08-03','8:00','5:00',NULL,'Y'),
(5,'08-04','1:00','5:00','Y',NULL),
(6,'08-04','5:00','7:00',NULL,'Y'),
(7,'08-04','7:00','10:00',NULL,'Y'),
(8,'08-04','10:00','13:00',NULL,'Y'),
(9,'08-05','8:00','5:00','Y',NULL)
;WITH CTE AS
(
SELECT
t1.[Date],
t1.TimeIn,
ISNULL(t2.TimeOut, t1.TimeOut) AS TimeOut,
ROW_NUMBER() OVER (PARTITION BY t1.[Date] ORDER BY t1.Id) AS RowNumber
FROM #Test AS t1
LEFT OUTER JOIN #Test AS t2 ON t1.TimeOut = t2.TimeIn AND t1.[Date] = t2.[Date]
)
SELECT
c.[Date],
(SELECT c2.TimeIn FROM CTE AS c2 WHERE c2.[Date] = c.[Date] AND c2.RowNumber = MIN(c.RowNumber)) AS TimeIn,
(SELECT c2.TimeOut FROM CTE AS c2 WHERE c2.[Date] = c.[Date] AND c2.RowNumber = MAX(c.RowNumber)) AS TimeOut
FROM CTE AS c
GROUP BY c.[Date]
You can use merge statements in tables where you have an identical column. You can identify the one or more columns that can be used to uniquely identify the row to be merged.
I have a simple problem. How can I add a unique constraint for a table, without relating the values to their columns? For example, I have this table
ID_A ID_B
----------
1 2
... ...
In that example, I have the record (1,2). For me, (1,2) = (2,1). So i don't want to allow my database to store both values. I know I can accomplish it using, triggers or checks and functions. But i was wondering if there is any instruccion like
CREATE UNIQUE CONSTRAINT AS A SET_CONSTRAINT
You could write a view like that:
select 1 as Dummy
from T t1
join T t2 on t1.ID1 = t2.ID2 AND t1.ID2 = t2.ID1 --join to corresponding row
cross join TwoRows
And create a unique index on Dummy. TwoRows is a table that contains two rows with arbitrary contents. It is supposed to make the unique index fail if there ever is a row in it. Any row in this view indicates a uniqueness violation.
You can do this using Instead of Insert trigger.
Demo
Table Schema
CREATE TABLE te(ID_A INT,ID_B INT)
INSERT te VALUES ( 1,2)
Trigger
Go
CREATE TRIGGER trg_name
ON te
instead OF INSERT
AS
BEGIN
IF EXISTS (SELECT 1
FROM inserted a
WHERE EXISTS (SELECT 1
FROM te b
WHERE ( ( a.id_a = b.id_b
AND a.id_b = b.id_a )
OR ( a.id_a = b.id_a
AND a.id_b = b.id_b ) )))
BEGIN
PRINT 'duplciate record'
ROLLBACK
END
ELSE
INSERT INTO te
SELECT Id_a,id_b
FROM inserted
END
SELECT * FROM te
Insert Script
INSERT INTO te VALUES (2,1) -- Duplicate
INSERT INTO te VALUES (1,2) --Duplicate
INSERT INTO te VALUES (3,2) --Will work
I have this statement:
insert into Admin.VersionHistory --do not know what to put here
select COUNT(*) as cnt
from membership.members as mm
left join aspnet_membership as asp
on mm.aspnetuserid=asp.userid
left join trade.tradesmen as tr
on tr.memberid=mm.memberid
where asp.isapproved = 0 and tr.ImportDPN IS NOT NULL and tr.importDPN <> ''
and it gives me a total of 179956. I want to write this total to another table called Admin.VersionHistory which has id(autoinc), version(varchar) and date(sysdate) columns,
How can I do this please?
Thanks
Your query returns resultset with one column and one row. It could be inserted in some table that has one integer column. Your target table is not suitable for this because it has three columns.
You should be able to do this:
INSERT INTO Admin.VersionHistory(ColumnName)
SELECT COUNT(*)
-- the resut of your query here
INSERT INTO Admin.VersionHistory (ColCount, version, Sysdate)
VALUES(
(SELECT COUNT(*) AS cnt FROM membership.members AS mm
lLEFT JOIN aspnet_membership AS asp ON mm.aspnetuserid = asp.userid
LEFT JOIN trade.tradesmen AS tr ON tr.memberid=mm.memberid
WHERE
asp.isapproved = 0 AND
tr.ImportDPN IS NOT NULL AND
tr.importDPN <> ''),
VERSIONVALUE, GETDATE())
Though I have tried similar thing in Oracle I guess it should not be very different in SQL.
Give it a shot.
When I execute my "select union select", I get the correct number or rows (156)
Executed independently, select #1 returns 65 rows and select #2 returns 138 rows.
When I use this "select union select" with an Insert into, I get 203 rows (65+138) with duplicates.
I would like to know if it is my code structure that is causing this issue ?
INSERT INTO dpapm_MediaObjectValidation (mediaobject_id, username, checked_date, expiration_date, notified)
(SELECT FKMediaObjectId, CreatedBy,#checkdate,dateadd(ww,2,#checkdate),0
FROM dbo.gs_MediaObjectMetadata
LEFT JOIN gs_MediaObject mo
ON gs_MediaObjectMetadata.FKMediaObjectId = mo.MediaObjectId
WHERE UPPER([Description]) IN ('CAPTION','TITLE','AUTHOR','DATE PHOTO TAKEN','KEYWORDS')
AND FKMediaObjectId >=
(SELECT TOP 1 MediaObjectId
FROM dbo.gs_MediaObject
WHERE DateAdded > #lastcheck
ORDER BY MediaObjectId)
GROUP BY FKMediaObjectId, CreatedBy
HAVING count(*) < 5
UNION
SELECT FKMediaObjectId, CreatedBy,getdate(),dateadd(ww,2,getdate()),0
FROM gs_MediaObjectMetadata yt
LEFT JOIN gs_MediaObject mo
ON yt.FKMediaObjectId = mo.MediaObjectId
WHERE UPPER([Description]) = 'KEYWORDS'
AND FKMediaObjectId >=
(SELECT TOP 1 MediaObjectId
FROM dbo.gs_MediaObject
WHERE DateAdded > #lastcheck
ORDER BY MediaObjectId)
AND NOT EXISTS
(
SELECT *
FROM dbo.fnSplit(Replace(yt.Value, '''', ''''''), ',') split
WHERE split.item in (SELECT KeywordEn FROM gs_Keywords) or split.item in (SELECT KeywordFr FROM gs_Keywords)
)
)
I would appreciate any clues into resolving this problem ...
Thank you !
The UNION keyword should only return distinct records between the two queries. However, if I recall correctly, this is only true if the datatypes are the same. The date variables might be throwing that off. Depending on the collation type, whitespace might be handled differently as well. You might want to do a SELECT DISTINCT on the dpapm_MediaObjectValidation table after doing your insert, but be sure to trim whitespace from both sides in your comparison. Another approach is to do your first insert, then on your second insert, forgo the UNION altogether and do a manual EXISTS check to see if the items to be inserted already exist.
