i'm trying to update column from another table which means :
SELECT DISTINCT id FROM creature WHERE map = 389;
This SQL will give me this result :
11323
11322
11324
11520
11321
What i want is to update creature_template lootid = 11323 where entry = 11323 so it goes as following :
UPDATE creature_template SET lootid = 11323 WHERE entry = 11323
I have tried this :
UPDATE creature_template SET lootid =
(SELECT DISTINCT id
FROM creature
WHERE map = 389) WHERE lootid = entry;
I'm sure it's incorrect simply it's not logic but couldn't find the logical answer for this.
Even REPLACE could work instead of UPDATE so any will work.
You need JOIN with UPDATE :
UPDATE creature_template ct
INNER JOIN creature c
ON c.id = ct.entry
SET ct.lootid = c.id
WHERE c.map = 389;

I'm trying to update a tablecolumn based on another value inside this table but I keep getting an error.
My query is as follows:
UPDATE partcreditor
SET partcreditor.creditorid = creditor.creditorid
FROM partcreditor
INNER JOIN creditor ON partcreditor.creditornr = creditor.creditornr
WHERE creditor.relgroupid = 1
AND creditor.creditortypeid = 1
UPDATE partcreditor AS PC
INNER JOIN creditor AS CR ON PC.creditornr = CR.creditornr
SET PC.creditorid = CR.creditorid
WHERE CR.relgroupid = 1 AND CR.creditortypeid = 1
No need to use the FROM clause in the update. As well as use alias name for better readability.
I've got two Queries to Update two tables:
First Table
UPDATE user_info SET `location` = ".$locationid.", `looking_for` = ".$lookingfor." WHERE `user_info`.`user_id` = ".$infoid.";
Second Table
UPDATE user_personality SET `personality` = '".$changedescription."' WHERE `user_personality`.`user_info_id` = ".$infoid.";
And I'm trying to merge those two Queries, using the same statement.
UPDATE user_info, user_personality
SET user_info.location = ".$locationid.", user_info.`looking_for` = ".$lookingfor.", user_personality.personality = '".$changedescription."'
WHERE `user_info`.`user_id` = ".$infoid."
AND `user_personality`.`user_info_id` = ".$infoid."
I'm not receiving any error message, but is not updating.
What am I doing wrong?
Thanks.
Just a guess...
"
UPDATE user_info i
JOIN user_personality p
ON p.user_info_id = i.user_id
SET i.location = $locationid
, i.looking_for = '$lookingfor'
, p.personality = '$changedescription'
WHERE i.user_id = $infoid;
";
If you set the 2 table fields equal to each other in the where clause it should work, so I believe you'd change your where clause to:
WHERE `user_info`.`user_id` = `user_personality`.`user_info_id`
AND `user_info`.`user_id` = ".$infoid."
MySQL definitely supports updating multiple tables, so the where clause that works for a multi table select statement should also work for an update.
Update product.tblproductinformation
SET Quantity = (Quantity-1)
where(Select iProduct.ProductID
from tblindividualproduct as iProduct
INNER JOIN tblproductinformation as pInfo ON iProduct.Code = pInfo.Code) = #p1"
i want to update my quantity to subtract 1. I also included inner join because my where is in another table. i got an error:
You cant specify target table 'tblproductinformation' for update in FROM clause
what's wrong?
You can use the multiple-table UPDATE syntax to join the tables directly:
UPDATE tblproductinformation AS pInfo
JOIN tblindividualproduct AS iProduct ON iProduct.Code = pInfo.Code
SET pInfo.Quantity = pInfo.Quantity - 1
WHERE iProduct.ProductID = #p1
I have had a read through a few of the other issues around joining on SQL Updates but haven't been able to finalise a query.
System is all in MySQL (INNODB table structure)
We are wanting to update an amount in one table that will increase an amount based on 2 variables from another table. There are a few constraints that need to be checked in the update to make sure the variables from the second table match the keys in the table to be updated
UPDATE as1
SET as1.amount = as1.amount + (b1.workers * b1.level)
FROM account_stock AS as1
INNER JOIN building AS b1 ON as1.accountID = b1.accountID
INNER JOIN building_seed AS bs1 ON bs1.buildingID = b1.buildingID
WHERE bs1.stockID = as1.stockID
AND b1.accountID = as1.accountID
AND b1.locID = as1.locID
AND b1.status = active
AND b1.gTime > 0
It's getting an error and I can't pick it. Sorry if it is a simple question, all my SQL is self taught so some of the habits I have aren't very good!
MySQL syntax for UPDATE is different. There is no FROM:
UPDATE
account_stock AS as1
INNER JOIN building AS b1 ON as1.accountID = b1.accountID
INNER JOIN building_seed AS bs1 ON bs1.buildingID = b1.buildingID
SET as1.amount = as1.amount + (b1.workers * b1.level)
WHERE bs1.stockID = as1.stockID
AND b1.locID = as1.locID
AND b1.status = active
AND b1.gTime > 0 ;
--- removed duplicate :
--- AND b1.accountID = as1.accountID
Also: is active a column or you meant to write?: AND b1.status = 'active'
Although there are many questions similar to this, such as
"Updating a record from another table", but i could not get this working.
I have a query that selects and updates table sem_stdexamfinresmark. The select subquery returns multiple rows of data whose size may not be equal to the table being updated, but the update is now working.
The query looks like :
update sem_stdexamfinresmark sr,
(select
se.currsession,
str.studentid,
str.classid,
str.subjectid,
str.aggScore*(select gbtp.percentage from gb_termpercentage gbtp where gbtp.termname = se.examtype)/100 as aggPer,
str.aggGrade
from
sem_stdexamtermresr str,
sem_exam se
where
str.examid=se.examid and
se.examtype = 'Second Term' and
se.currsession =1 and classid='8'
) s
set
sr.SecondTermMark = s.aggPer and
sr.SecondTermGrade = s.aggGrade
where
sr.studentid=s.studentid and
sr.subjectid=s.subjectid and
s.currsession = s.currsession and
sr.classid='8';
EDIT:
update sem_stdexamfinresmark
set
sr.SecondTermMark = s.aggPer and
sr.SecondTermGrade = s.aggGrade
from
(select
se.currsession,
str.studentid,
str.classid,
str.subjectid,
str.aggScore*(select gbtp.percentage from gb_termpercentage gbtp where gbtp.termname = se.examtype)/100 as aggPer,
str.aggGrade
from
sem_stdexamtermresr str,
sem_exam se
where
str.examid=se.examid and
se.examtype = 'Second Term' and
se.currsession = 1 and classid='8'
) s
where
sr.studentid=s.studentid and
sr.subjectid=s.subjectid and
s.currsession =1 and
sr.classid='8';
select * from sem_exam;
update sem_exam set currsession =1;
try something that looks more like:
update foo
set col = bar.col
from bar
where ...
This is what happens when one loses sleep :( I just did a silly mistake here and added "and"
