SELECT `pro`.`St`, `s`.`Quantity`
FROM `s`
LEFT JOIN `web`.`pro` ON `s`.`Pro_id` = `pro`.`ProdID`
the above query results in a table like
st quantity
132 1
11 1
st is from one table and quantity is from another
using this select statement I want to add the resulting quantity to the st row in the other table.
Basically updating the second table by adding the quantity i get from this select statement.
UPDATE `web`.`pro`
SET `pro`.`st` = `pro`.`st` + `s`.`Quantity`
FROM `web`.`pro`
JOIN `shopping cart` `s`
ON `s`.`Pro_id` = `pro`.`ProdID`;
Something like that ?

I have a table Product with 240 000 rows.
I want to select from this table data where idproduct = idproductcomponent
Output makes a table with 3 columns A12345678 35655455952625 9638520963258960, so in different column.
Always idproductcomponent of idproducttype 1 is 0, and idproductcomponent of idproducttype 2,3 are the same of idproduct of idproducttype 1.
Pelase, can you share with me any idea for this select ?
Assuming your database is SQL Server (you don't say which one it is) the query could look like:
select
a.name,
b.name,
c.name
from t a
left join t b on b.idproductcomponent = a.idproduct and b.idproducttype = 2
left join t c on c.idproductcomponent = a.idproduct and c.idproducttype = 3
where a.idproducttype = 1
and a.idproduct = 11163 -- parameter you are searching for
To increase the performance of this query you can add the index:
create index ix1 on t (idproductcomponent);
I have two tables
Price
RET_ID DBS_ID RRP
Database
DBS_ID PRO_ID
I would like to use UPDATE such that I can increase RRP in the Price table by 20% if the PRO_ID in the Database table is = 1
UPDATE
( SELECT RRP
FROM PRICE
JOIN database
ON database.dbs_id = price.dbs_id
)
SET rrp = 100
WHERE (database.pro_ID = 1);
I've been trying all manner of INNER JOIN ... ON to no avail.
Thanks.
You can put the filtering condition in the where clause. Here is a method using exists:
update price p
set rpr = rpr * 1.2
where exists (select 1
from database d
where d.dbs_id = p.dbs_id and d.pro_id = 1
);
Here is another way using in:
update price p
set rpr = rpr * 1.2
where p.dbs_id in (select d.dbs_id
from database d
where d.pro_id = 1
);
You can use this query
MERGE INTO PRICE P
USING DATABASE D ON
(P.DBS_ID=D.DBS_ID) AND
D.PRO_ID=1
WHEN MATCHED
THEN
UPDATE SET
P.RRP=P.RRP*1.2;
When you are updating table from another table, always use MERGE function which is an amazing concept in SQL
UPDATE Price P SET RRP = RRP*1.2
WHERE EXISTS
(select 1 from Database
where DBS_ID = P.DBS_ID AND PRO_ID = 1);
I am trying to create an update query that will update my table values based on pallet number match.
SELECT [pallet] [quantity]
FROM dba.Inventory
This will returns 2 columns, one with pallet and the other with count.
I need to put this in a update statement that will match each pallet between here and table TABLE1 and update the counts in TABLE1
Use Common Table Expression.
Syntax goes like
with CTE_Values()
AS
( --- Your Statement---)
Update T
Set Col = C.col
From Table T Join CTE_Values C
On .....
I think that one easy solution (without evaluating the SELECT itself that looks quite convoluted) is to put the whole SELECT into a CTE and use it as source for your update. Something like this:
;WITH SrcCte AS (
SELECT pallet, SUM(total) as quantity
FROM (
SELECT r1.pallet, total
FROM
(SELECT plet_nbr, COUNT(serl_nbr) as total FROM Inventory group by plet_nbr )c1
right join
(select pallet from dbo.RFS where status NOT LIKE 'Not Available')r1
on r1.pallet = c1.plet_nbr
UNION all
Select r2.pallet, sum(iloc_qty) as total
FROM
(SELECT plet_nbr, iloc_qty FROM Inventory WHERE([matl_nbr] Like '#%')) c2
right join
(select pallet from dbo.RFS where status NOT LIKE 'Not Available') r2
on r2.pallet = c2.plet_nbr
where iloc_qty is not null
GROUP BY r2.pallet
)
AS final
GROUP BY pallet
)
UPDATE Dest
SET Dest.Cnt = Src.Quantity
FROM Table1 AS Dest
JOIN SrcCte AS Src ON Src.pallet = Dest.pallet
I am going to explain again what I am trying to do in hopes that you can help.
Table 1 has 4061 rows with columns that include
[Name],[Address1],[Address2],[Address3],[City],[State],[Zip],[Country],[Phone]
and 20 other columns. Table 1 is data that needs to be deidentified. Table 1 has 1534 distinct [Name] rows out of 4061 rows total.
Table 2 has auto generated data which includes the same columns. I would like to replace the above mentioned columns in table 1 with data from table 2. I want to select distinct based on [Name] from table one and then [Name],[Address1],[Address2],[Address3],[City],[State],[Zip],[Country],[Phone] with a new set of distinct data from table 2.
I do not want to just update each row with a new address as that will screw up the data consistency. By replacing only distinct this will allow me to preserve the data consistency while changing the row data in table 1. When I am done I would like to have 1534 distinct new de-identified [Name] [Address1],[Address2],[Address3],[City],[State],[Zip],[Country],[Phone] in table 1 from table 2.
You would use join in the update. You can generate a join key for 1500 rows using row_number():
update toupdate
set t.address = f.address
from (select t.*, row_number() over (order by newid()) as seqnum
from table t
) toupdate join
(select f.*, row_number() over (order by newid()) as seqnum
fake f
) f
on toupdate.seqnum = f.seqnum and t.seqnum <= 1500;
Here is how I ended up doing it.
First I ran a statement to select distinct and inserted it into a table.
Select Distinct [Name],[Address1],[City],[State],[Zip],[Country],[Phone]
INTO APMAST2
FROM APMAST
I then added name2 column in APMAST2 and used a statement to create a sequential id field into APMAST2.
DECLARE #id INT
SET #id = 0
UPDATE APMAST2
SET #id = id = #id + 1
GO
Now I have my distinct info plus a blank name field and a sequential ID field in APMAST2. Now I can join this date with my fakenames table which I generated from. HERE using their bulk tool.
Using a Join Statement I joined my fake data with APMAST2
Update dbo.APMAST2
SET dbo.APMAST2.Name = dbo.fakenames.company,
dbo.APMAST2.Address1 = dbo.fakenames.streetaddress,
dbo.APMAST2.City = dbo.fakenames.City,
dbo.APMAST2.State = dbo.fakenames.State,
dbo.APMAST2.Zip = dbo.fakenames.zipcode,
dbo.APMAST2.Country = dbo.fakenames.countryfull,
dbo.APMAST2.Phone = dbo.fakenames.telephonenumber
FROM
dbo.APMAST2
INNER JOIN
dbo.fakenames
ON dbo.fakenames.number = dbo.APMAST2.id
Now I have my fake data loaded but I kept my original Name field so I could reload this data into my full table ARMAST so now I can do a join between ARMAST2 and ARMAST.
Update dbo.APMAST
SET dbo.APMAST.Name = dbo.APMAST2.Name,
dbo.APMAST.Address1 = dbo.APMAST2.Address1,
dbo.APMAST.City = dbo.APMAST2.City,
dbo.APMAST.State = dbo.APMAST2.State,
dbo.APMAST.Zip = dbo.APMAST2.Zip,
dbo.APMAST.Country = dbo.APMAST2.Country,
dbo.APMAST.Phone = dbo.APMAST2.Phone
FROM
dbo.APMAST
INNER JOIN
dbo.apmast2
ON dbo.apmast.name = dbo.APMAST2.name2
Now my original table has all fake data in it but it keeps the integrity it had , well most of it, so the data looks good when reported on but is de-identified. You can now remove APMAST2 or keep it if you need to match this with other data later on. I know this is long and I am sure there is a better way to do it but this is how I did it, suggestions welcome.
Table 1 looks like the following.
ID SIZE TYPE SERIAL
1 4 W-meter1 123456
2 5 W-meter2 123456
3 4 W-meter 585858
4 4 W-Meter 398574
As you can see. Items 1 and 2 both have the same Serial Number. I have an innerjoin update statement that will update the UniqueID on these devices based on linking their serial number to the list.
What I would like to do. Is modify by hand the items with duplicate serial numbers and scripted update the ones that are unique. Im presuming I have to reference the distinct command here somewhere buy not sure.
This is my update statement as is. Pretty simple and straight forward.
update UM00400
Set um00400.umEquipmentID = tb2.MIUNo
from UM00400 tb1
inner join AA_Meters tb2 on
tb1.umSerialNumber = tb2.Old_Serial_Num
where tb1.umSerialNumber <> tb2.New_Serial_Num
;WITH CTE
AS
(
SELECT * , rn = ROW_NUMBER() OVER (PARTITION BY SERIAL ORDER BY SERIAL)
FROM UM00400
)
UPDATE CTE
SET CTE.umEquipmentID = tb2.MIUNo
inner join AA_Meters tb2
on CTE.umSerialNumber = tb2.Old_Serial_Num
where tb1.umSerialNumber <> tb2.New_Serial_Num
AND CTE.rn = 1
This will update the 1st record of multiple records with the same SERIAL.
If i understand your question correctly below query will help you out :
;WITH CTE AS
(
// getting those serial numbers which are not duplicated
SELECT umSerialNumber,COUNT(umSerialNumber) as CountOfSerialNumber
FROM UM00400
GROUP BY umSerialNumber
HAVING COUNT(umSerialNumber) = 1
)
UPDATE A SET A.umEquipmentID = C.MIUNo
FROM UM00400 A
INNER JOIN CTE B ON A.umSerialNumber = B.umSerialNumber
INNER JOIN AA_Meters C ON A.umSerialNumber = C.Old_Serial_Num
