Good Day Guys. Im creating sql syntax which subtract the current value of ContractQty to TotalAmountQty.
The code Below subtract ContractQty and TotalAmountQty in Temporary Table. My Question is how can I update the value of ContractQty to my Table Retail. XDeal ColumnName ContractQty where DocNumber. getting the data from Temporary Table? The value in the screen shoot need to get and update my column ContractQty in Retail.XDeal Thanks Regards
WITH A AS (SELECT A.DocNumber,SUM(B.Qty) AS TotalAmountQty
FROM Retail.XDeal A
INNER JOIN Retail.XDealDetail B
ON A.DocNumber = B.DocNumber
GROUP BY A.DocNumber)
SELECT SUM(A.ContractQty-B.TotalAmountQty) as ContractQty FROM Retail.XDeal A
INNER JOIN A B
ON A.DocNumber = B.DocNumber
You can do an update with a join in SQL Server. This is the syntax:
WITH A AS (
SELECT xd.DocNumber, SUM(xdd.Qty) AS TotalAmountQty
FROM Retail.XDeal xd INNER JOIN
Retail.XDealDetail xdd
ON xd.DocNumber = xdd.DocNumber
GROUP BY xd.DocNumber
)
UPDATE xd
SET ContractQty = A.TotalAmountQty
FROM Retail.XDetail xd JOIN
A
ON xd.DocNumber = A.DocNumber;
The join for A is unnecessary, so this is a simpler version:
WITH A AS (
SELECT xdd.DocNumber, SUM(xdd.Qty) AS TotalAmountQty
FROM Retail.XDealDetail xdd
GROUP BY xdd.DocNumber
)
UPDATE xd
SET ContractQty = A.TotalAmountQty
FROM Retail.XDetail xd JOIN
A
ON xd.DocNumber = A.DocNumber;
Personally, I would make the CTE a subquery, but that is just a matter of preference.
I think I understand what you're trying to do; this should work:
SELECT DocNumber, SUM(Qty) AS TotalAmountQty
INTO #temp
FROM Retail.XDealDetail
GROUP BY DocNumber
UPDATE Retail.XDeal
SET ContractQty = A.ContractQty - B.TotalAmountQty
FROM Retail.XDeal A
JOIN #temp B ON A.DocNumber = B.DocNumber;
DROP TABLE #temp;
You don't mention version of sql-server, but recent versions support MERGE:
MERGE INTO Retail.XDeal xd2
USING (
SELECT xd.DocNumber, SUM(xdd.Qty) AS TotalAmountQty
FROM Retail.XDeal xd
JOIN Retail.XDealDetail xdd
ON xd.DocNumber = xdd.DocNumber
GROUP BY xd.DocNumber
) y
ON xd2.DocNumber = y.DocNumber
WHEN MATCHED THEN
UPDATE SET xd2.ContractQty = y.TotalAmountQty
As I did not fully understand your scenario, this probably does not do what you want, but it should give you an idea on how to use MERGE

I have to update a field with a value which is returned by a join of 3 tables.
Example:
select
im.itemid
,im.sku as iSku
,gm.SKU as GSKU
,mm.ManufacturerId as ManuId
,mm.ManufacturerName
,im.mf_item_number
,mm.ManufacturerID
from
item_master im, group_master gm, Manufacturer_Master mm
where
im.mf_item_number like 'STA%'
and im.sku=gm.sku
and gm.ManufacturerID = mm.ManufacturerID
and gm.manufacturerID=34
I want to update the mf_item_number field values of table item_master with some other value which is joined in the above condition.
How can I do this in MS SQL Server?
UPDATE im
SET mf_item_number = gm.SKU --etc
FROM item_master im
JOIN group_master gm
ON im.sku = gm.sku
JOIN Manufacturer_Master mm
ON gm.ManufacturerID = mm.ManufacturerID
WHERE im.mf_item_number like 'STA%' AND
gm.manufacturerID = 34
To make it clear... The UPDATE clause can refer to an table alias specified in the FROM clause. So im in this case is valid
Generic example
UPDATE A
SET foo = B.bar
FROM TableA A
JOIN TableB B
ON A.col1 = B.colx
WHERE ...
Adapting this to MySQL -- there is no FROM clause in UPDATE, but this works:
UPDATE
item_master im
JOIN
group_master gm ON im.sku=gm.sku
JOIN
Manufacturer_Master mm ON gm.ManufacturerID=mm.ManufacturerID
SET
im.mf_item_number = gm.SKU --etc
WHERE
im.mf_item_number like 'STA%'
AND
gm.manufacturerID=34
One of the easiest way is to use a common table expression (since you're already on SQL 2005):
with cte as (
select
im.itemid
,im.sku as iSku
,gm.SKU as GSKU
,mm.ManufacturerId as ManuId
,mm.ManufacturerName
,im.mf_item_number
,mm.ManufacturerID
, <your other field>
from
item_master im, group_master gm, Manufacturer_Master mm
where
im.mf_item_number like 'STA%'
and im.sku=gm.sku
and gm.ManufacturerID = mm.ManufacturerID
and gm.manufacturerID=34)
update cte set mf_item_number = <your other field>
The query execution engine will figure out on its own how to update the record.
Did not use your sql above but here is an example of updating a table based on a join statement.
UPDATE p
SET p.category = c.category
FROM products p
INNER JOIN prodductcatagories pg
ON p.productid = pg.productid
INNER JOIN categories c
ON pg.categoryid = c.cateogryid
WHERE c.categories LIKE 'whole%'
You can specify additional tables used in determining how and what to update with the "FROM " clause in the UPDATE statement, like this:
update item_master
set mf_item_number = (some value)
from
group_master as gm
join Manufacturar_Master as mm ON ........
where
.... (your conditions here)
In the WHERE clause, you need to provide the conditions and join operations to bind these tables together.

MySQL: In general, make necessary changes par your requirement:
UPDATE
shopping_cart sc
LEFT JOIN
package pc ON sc. package_id = pc.id
SET
sc. amount = pc.amount
It is very simple to update using join query in SQL .You can do it without using FROM clause. Here is an example :
UPDATE customer_table c
JOIN
employee_table e
ON c.city_id = e.city_id
JOIN
anyother_ table a
ON a.someID = e.someID
SET c.active = "Yes"
WHERE c.city = "New york";
You can use the following query:
UPDATE im
SET mf_item_number = (some value)
FROM item_master im
JOIN group_master gm
ON im.sku = gm.sku
JOIN Manufacturer_Master mm
ON gm.ManufacturerID = mm.ManufacturerID
WHERE im.mf_item_number like 'STA%' AND
gm.manufacturerID = 34 `sql`
Try like this...
Update t1.Column1 = value
from tbltemp as t1
inner join tblUser as t2 on t2.ID = t1.UserID
where t1.[column1]=value and t2.[Column1] = value;
If you are using SQL Server you can update one table from other table without specifying a join and simply link the two tables from the where clause. This makes a much simpler SQL query:
UPDATE Table1
SET Table1.col1 = Table2.col1,
Table1.col2 = Table2.col2
FROM
Table2
WHERE
Table1.id = Table2.id
You can update with MERGE Command with much more control over MATCHED and NOT MATCHED:(I slightly changed the source code to demonstrate my point)
USE tempdb;
GO
IF(OBJECT_ID('target') > 0)DROP TABLE dbo.target
IF(OBJECT_ID('source') > 0)DROP TABLE dbo.source
CREATE TABLE dbo.Target
(
EmployeeID INT ,
EmployeeName VARCHAR(100) ,
CONSTRAINT Target_PK PRIMARY KEY ( EmployeeID )
);
CREATE TABLE dbo.Source
(
EmployeeID INT ,
EmployeeName VARCHAR(100) ,
CONSTRAINT Source_PK PRIMARY KEY ( EmployeeID )
);
GO
INSERT dbo.Target
( EmployeeID, EmployeeName )
VALUES ( 100, 'Mary' );
INSERT dbo.Target
( EmployeeID, EmployeeName )
VALUES ( 101, 'Sara' );
INSERT dbo.Target
( EmployeeID, EmployeeName )
VALUES ( 102, 'Stefano' );
GO
INSERT dbo.Source
( EmployeeID, EmployeeName )
VALUES ( 100, 'Bob' );
INSERT dbo.Source
( EmployeeID, EmployeeName )
VALUES ( 104, 'Steve' );
GO
SELECT * FROM dbo.Source
SELECT * FROM dbo.Target
MERGE Target AS T
USING Source AS S
ON ( T.EmployeeID = S.EmployeeID )
WHEN MATCHED THEN
UPDATE SET T.EmployeeName = S.EmployeeName + '[Updated]';
GO
SELECT '-------After Merge----------'
SELECT * FROM dbo.Source
SELECT * FROM dbo.Target
Let me just add a warning to all the existing answers:
When using the SELECT ... FROM syntax, you should keep in mind that it is proprietary syntax for T-SQL and is non-deterministic. The worst part is, that you get no warning or error, it just executes smoothly.
Full explanation with example is in the documentation:
Use caution when specifying the FROM clause to provide the criteria for the update operation. The results of an UPDATE statement are undefined if the statement includes a FROM clause that is not specified in such a way that only one value is available for each column occurrence that is updated, that is if the UPDATE statement is not deterministic.
I've been trying to do things like this forever and it just occurred to me to try using the following syntax (using tuples)
update dstTable T
set (T.field1, T.field2, T.field3) =
(select S.value1, S.value2, S.value3
from srcTable S
where S.key = T.Key);
And surprisingly it worked. I'm using Oracle (12c I think). Is this standard SQL or Oracle specific?
NB: In my example I'm updating the entire table (filling new columns). The update has no where clause so all rows will be updated. Your fields will be set to NULL when the subquery doesn't return a row. (and it must not return more than one row).
could you please help me on the below query?
Using the query
SELECT LineGernal.Id, LineGernal.Description, LineGernal.SSMS, BaseAddOns.Id
from LineGernal Inner Join
BaseAddOns
on LineGernal.Id=BaseAddOns.ParentLineGernalID
Output-
Result Needed-
Thanks
Rajendra
You can use group by and min as follows:
SELECT LineGernal.Id, LineGernal.Description, LineGernal.SSMS, min(BaseAddOns.Id) as id
from LineGernal Inner Join
BaseAddOns
on LineGernal.Id=BaseAddOns.ParentLineGernalID
GROUO BY LineGernal.Id, LineGernal.Description, LineGernal.SSMS
I would recommend pre-aggregation in a subquery:
select li.id as lineGeneralId, lg.description, lg.ssms, bao.id as BaseAddOnsId
from LineGernal lg
inner join (
select ParentLineGernalID, min(id) as id
from BaseAddOns
group by ParentLineGernalID,
) bao on lg.id = bao.ParentLineGernalID

We have 5 tables and we are trying to create a view to get the results.
Below is the view which is working fine.
I need suggestions. Is it a good practice to write this query in this way or it can be optimized in a better way.
SELECT p.Pid, hc.hcid, hc.Accomodation, ghc.ghcid, ghc.ProductFeatures, wp.existing, wp.acute, mc.cardiaccover, mc.cardiaclimitationperiod
FROM TableA p
LEFT JOIN TableB hc
ON p.pid = hc.pid
LEFT JOIN TableC ghc
ON p.pid = ghc.pid
LEFT JOIN (SELECT *
FROM (SELECT hcid,
title,
wperiodvalue + '-' + CASE WHEN
wperiodvalue > 1 THEN
unit +
's' ELSE
unit END wperiod
FROM TableD) d
PIVOT ( Max(wperiod)
FOR title IN (acute,
existing
) ) piv1) wp
ON hc.hcid = wp.hcid
LEFT JOIN (SELECT *
FROM (SELECT hcid,
title + col new_col,
value
FROM TableE
CROSS apply ( VALUES (cover,
'Cover'),
(Cast(limitationperiod AS
VARCHAR
(10)),
'LimitationPeriod') ) x (value, col
)) d
PIVOT ( Max(value)
FOR new_col IN (cardiaccover,
cardiaclimitationperiod,
cataracteyelenscover,
cataracteyelenslimitationperiod
) ) piv2) mc
ON hc.hcid = mc.hcid
Any suggestions would be appreciated.
Thanks
My suggestion is to break down the query using temporary table, create stored procedure then dump data in the one new table and with the help of that table you can create view:
Store both PIVOT result in tow seperate temp tables as
SELECT * INTO #pvtInfo FROM ( --first PIVOT query
SELECT * INTO #pvtInfoTwo FROM ( --second PIVOT query
Then your final query will be as :
SELECT p.Pid,
hc.hcid,
hc.Accomodation,
ghc.ghcid,
ghc.ProductFeatures,
wp.existing,
wp.acute,
mc.cardiaccover,
mc.cardiaclimitationperiod
FROM TableA p
LEFT JOIN TableB hc ON p.pid = hc.pid
LEFT JOIN TableC ghc ON p.pid = ghc.pid
LEFT JOIN #pvtInfo wp ON hc.hcid = wp.hcid
LEFT JOIN #pvtInfoTwo mc ON hc.hcid = mc.hcid
First you can try then only go with SP and VIEW.
Hope, It will help.
Alright, I have to create a similar table structure to mine more simplified -
Test_Table: EmployeeId,Points,Date
Test_Table1:Score,EmployeeId,Date
Leaderboards_Table: Points,Score,EmployeeId,Day,Month,Year
Now I need to write a single query to update or insert into LeaderBoards_Table something like -
UPDATE Leaderboards_Table
SET Points=pts,Score=total_score
FROM
(
(SELECT
(SELECT SCORE from Test_Table1 WHERE Employee = #EmployeeId AND DAY(DATE)=10 AND MONTH(DATE)=12 AND YEAR(DATE)=2010) as pts
)
Points as pts
from Test_Table where Employee = #EmployeeId AND DAY(DATE)=10 AND MONTH(DATE)=12 AND YEAR(DATE)=2010
)
WHERE EmployeeId=#EmployeeId and DAY=10 AND MONTH=12 AND YEAR=2010
Now the above query only updates for today...what I want to do is also update yesterday
also in a single query I dont want to write another query....so is there anyway to do a single query to update yesterday and today's points.
UPDATE: Also this query will be called lot of times..so it would be great to have the most performance effective query for this.
Its a lot easier if you change to joins instead of subqueries.
UPDATE Leaderboards_Table
SET
Points=t1.score,
Score=total_score
FROM
Leaderboards_Table lt
INNER JOIN Test_Table1 t1
ON lt.employee_ID = t1.employee_id
INNER JOIN Test_Table t
ON lt.employee_ID = t1.employee_id
and lt.date = t1.date
WHERE
EmployeeId=#EmployeeId and DAY IN (9,10) AND MONTH=12 AND YEAR=2010
Here's a solution that uses the BETWEEEN clause.
UPDATE Leaderboards_Table
SET Points=tt.Points, Score = tt1.Score
FROM LeaderBoards_Table
JOIN Test_Table1 tt1 ON LeaderBoards_Table.EmployeeId = tt1.EmployeeId
JOIN Test_Table tt ON tt1.EmployeeId = tt.EmployeeId
WHERE EmployeeId = #EmployeeId
AND CONVERT(datetime CAST(YEAR AS varchar) + CAST(MONTH AS varchar) + CAST(DAY AS varchar))
BETWEEN '20101209' AND '20101210'
