UPDATE user SET
tw_oauth_token=(SELECT tw_oauth_token FROM user WHERE id=27),
tw_oauth_token_secret = (SELECT tw_oauth_token_secret FROM user WHERE id=27),
tw_user_id = (SELECT tw_user_id FROM user WHERE id=27),
handler = (SELECT handler FROM user WHERE id=27),
merged=1 WHERE id=26
The idea is to select data from user table where id = 27 and update the same table where id = 26.
I am having the following error:
#1093 - You can't specify target table 'user' for update in FROM clause
Any help would be appreciated. Thanks
UPDATE user a
CROSS JOIN user b
SET a.tw_oauth_token = b.tw_oauth_token,
a.tw_oauth_token_secret = b.tw_oauth_token_secret,
a.tw_user_id = b.tw_user_id,
a.handler = b.handler,
a.mrged = 1
WHERE a.ID = 26 AND
b.ID = 27
Why don't you try to create a virtual table based on your table then update the user table with SELECT statements on that View. Something like this:
CREATE VIEW view_user AS
SELECT *
FROM user;
And then use the view_user in the update.

DataBase_1 has a list of users with their vBulletinId
DataBase_2 has the vBulletin users with their vBulletinId and UserGroupId
I want to find all vBulletin users from Database_2, who are NOT in Database_1, and change their UserGroupId to 15
UPDATE database_2.user
SET
usergroupid = 15
WHERE
(
SELECT UserId
FROM database_2.user
WHERE UserId NOT IN
(
SELECT vBulletinId
FROM database_1.Users
)
);
Currently I am getting a "You can't specify target table 'user' for update in FROM clause"
Any help would be great. thanks.
=== SOLUTION ===
A simplified solution that worked.
UPDATE database_2.user
SET
usergroupid = 15
WHERE userid NOT IN
(
SELECT vBulletinId FROM database_1.Users
);
UPDATE database_2.user
LEFT JOIN database_1.Users ON database_2.user.UserId = database_1.Users.vBulletinId
SET database_2.user.usergroupid = 15
WHERE database_1.Users.vBulletinId IS NULL
or
UPDATE database_2.user
SET database_2.user.usergroupid = 15
WHERE NOT EXISTS ( SELECT NULL
FROM database_1.Users
WHERE database_2.user.UserId = database_1.Users.vBulletinId )
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.
I need to fill some fields in a table getting informations from other records of the same table.
I tried to write a query to explain what I want to do:
update globale2
set
nita = t.nita,
tita = t.tita,
notaita = t.notaita
where
neng = t.neng and
nita is null
(select nita, neng, tita, notaita from globale where uris='mma' and nita is not null) as t
edit to eplain better:
every records have these fields: "nita", "tita", "notaita", "neng" ("neng" cannot be null)
I want to fill these fields: "nita", "tita", "notaita" (where "nita" is empty)
with the same values from another record where "neng" equals the other "neng"
You can however, join the two tables.
UPDATE globale2 g
INNER JOIN globale gg
ON g.neng = gg.neng
SET g.nita = gg.nita,
g.tita = gg.tita,
g.notaita = gg.notaita
WHERE g.nita IS NULL
AND gg.uris = 'mma'
AND gg.nita IS NOT NULL
assume there is a table A_temp, with two columns 'one' and 'two'.
TABLE A_temp
ONE TWO
1 2
this is the present status of the table.
The query
UPDATE (SELECT * FROM A_temp ) A SET one = A.two where one = '1'
updates the table as
ONE TWO
2 2
Hope you get the idea and that it helps..
I'm trying to update a table based on 2 select subquery that will be multipied to produce the value for Harga column
here is my code :
UPDATE bahanmakanan
SET Harga = (SELECT HargaSatuan from detail_bahanmakanan
WHERE IDBahanMakanan = "BM01")* (SELECT jumlah from bahanmakanan
WHERE IDBahanMakanan = "BM01")
WHERE IDBahanMakanan = "BM01" ;
The error message return
Error Code: 1093. You can't specify target table 'bahanmakanan' for update in FROM clause
you can simply do this using JOIN,
UPDATE bahanmakanan a
INNER JOIN detail_bahanmakanan b
ON a.IDBahanMakanan = b.IDBahanMakanan
SET a.Harga = a.jumlah * b.HargaSatuan
WHERE a.IDBahanMakanan = 'BM01'
Please do backup first your database before executing the statement.
Try this:
UPDATE bahanmakanan as t1
JOIN detail_bahanmakanan as t2 USING(IDBahanMakanan)
SET t1.Harga = t2.HargaSatuan * t1.jumlah
WHERE IDBahanMakanan = "BM01";
I need to re-write the following Oracle 10g query to work in SQL Server 2008
It's an update query, where some field are retrieved from a SELECT and some are given (from code).
UPDATE "BMAN_SQL"."CELLS_GLIST"
SET ("GLIST_ID", "GLIST_VALUE_ID") = (
SELECT "GLIST_ID", "GLIST_VAL_ID"
FROM "BMAN_SQL"."GLISTS_VAL_UOR"
WHERE ("UOR_ID"=3)
AND ("GLIST_CODE"='X')
),
"SESSION_ID" = 1553245736,
"USER_ID" = 13
WHERE EXISTS ( SELECT * FROM ... )
Note that I need to use the UPDATE SET ... WHERE EXIST ... structure for compatibility with Oracle (query are automatically built by a QueryBuilder class for each specific DBMS).
I also cannot write:
UPDATE "BMAN_SQL"."CELLS_GLIST"
SET ("GLIST_ID", "GLIST_VALUE_ID", "SESSION_ID", "USER_ID") = (
SELECT "GLIST_ID", "GLIST_VAL_ID", 1553245736, 13
FROM "BMAN_SQL"."GLISTS_VAL_UOR"
WHERE ("UOR_ID"=3)
AND ("GLIST_CODE"='X')
)
WHERE EXISTS ( SELECT * FROM ... )
because (as per this old thread Oracle "Cannot update to NULL") it returns an error if the SELECT does not fetch any record.
Thanks in advance!
You need to join update query in this case. Please see syntax below. <Your condition here> Replace this section with your join condition here.
UPDATE m
SET
GLIST_ID = r.GLIST_ID
,GLIST_VALUE_ID = r.GLIST_VAL_ID
, SESSION_ID= 1553245736
, USER_ID = 13
from BMAN_SQL.CELLS_GLIST m
inner join BMAN_SQL.GLISTS_VAL_UOR r on <Your condition here>
WHERE
r.UOR_ID=3 AND (r.GLIST_CODE='X') AND
EXISTS ( SELECT * FROM ... )
EDIT
UPDATE BMAN_SQL.CELLS_GLIST
SET
GLIST_ID = (SELECT TOP 1 GLIST_ID FROM BMAN_SQL.GLISTS_VAL_UOR WHERE (UOR_ID=3) AND (GLIST_CODE='X'))
,GLIST_VALUE_ID = (SELECT TOP 1 GLIST_VAL_ID FROM BMAN_SQL.GLISTS_VAL_UOR WHERE (UOR_ID=3) AND (GLIST_CODE='X'))
,SESSION_ID = 1553245736
,USER_ID = 13
WHERE EXISTS ( SELECT * FROM ... )
