I have the following SQL code:
SELECT
`table1`.`field1`
, `view1`.`newfield1`
FROM
`table1`
INNER JOIN `GCOTDA2`.`view1`
ON (`table1`.`id1` = `view1`.`id1`) AND (`table1`.`id2` = `view1`.`id2`);
The query works fine but now I want to copy the view1.newfield1 to table1.field1. Thus, I wrote the following statement:
UPDATE `table1`
SET
`table1`.`field1` = `view1`.`newfield1`
FROM
`table1`
INNER JOIN `view1`
ON (`table1`.`id1` = `view1`.`id1`) AND (`table1`.`id2` = `view1`.`id2`);
However, the update does not work and I got this error message:
Error Code: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM
`table1`
INNER JOIN `view1`
' at line 4
I checked on google and other questions in this site such as: How do I UPDATE from a SELECT in SQL Server? and Error Code: 1064 in mysql with no luck. (MySQL Server 5.5.27)
I need someone to illuminate me, thanks!
Try this on for size:
UPDATE 'table1` t JOIN `view1` v
ON t.id1 = v.id1 AND t.id2 = v.id2
SET t.field1 = v.newfield1
You can do this with a subquery:
update
table1
set
table1.field1 = (select view1.newfield1 from view1 where view1.id1 = table1.id1 and view1.id2 = table1.id2)
where
exists (select null from view1 where view1.id1 = table1.id1 and view1.id2 = table1.id2)

Please help me where is an error in this query? and How can I resolve this error?
Not sure what you intended, but for the error, you want to apply the count function inside the subquery:
select message.id as message_id,
pet_info.id as pet_id,
pet_info.pet_hidenum as hidenum,
lostpets.pet_lost_date as pet_lost_date,
lostpets.type as status,
pet_images.img as img,
(
select COUNT(*)
from message
where message.status = 'not seen'
) as unread
from message
left join pet_info on pet_info.id = message.pet_id
left join pet_images on pet_images.petid = message.pet_id
left join lostpets on lostpets.petid = message.pet_id
Also try to not use backticks by using standard aliases and identifier names because the backticks hinder readability.
If that's not what you want, please edit your question and add sample data and expected output.
UPDATE newsreactions
SET newsreactions.enabled = '0'
FROM newsreactions
INNER JOIN users ON newsreactions.memberId = users.id
WHERE users.active = '0' AND users.comment LIKE '%spam%'
For some reason I'm getting a syntax error:
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM newsreactions INNER JOIN users ON newsreactions.memberId = users.id WHERE u' at line 3
Can't figure it out though.
If I replace the update and set by a select it works fine.
Error 1064 is a MySQL syntax error. The correct MySQL syntax is:
UPDATE newsreactions nr INNER JOIN
users u
ON nr.memberId = u.id
SET nr.enabled = 0
WHERE u.active = 0 AND u.comment LIKE '%spam%';
Notes:
The JOIN goes in the UPDATE clause.
Table aliases makes the query easier to write and to read.
I am guessing that enabled and active are really numeric values. If so, do not use single quotes.
The join clause should come before the set clause, and there should be no from clause in MySQL:
UPDATE newsreactions
JOIN users ON newsreactions.memberId = users.id
SET newsreactions.enabled = '0'
WHERE users.active = '0' AND users.comment LIKE '%spam%'
I have a query like this
UPDATE t_prd_cost_compare
SET
2015_AUG_PRD_UNIT_PRICE=i.PRD_UNIT_PRICE,
2015_AUG_PRD_SELLING_PRICE=i.PRD_SELLING_PRICE,
2015_AUG_PRD_IN_PATIENT_LIST_PRICE=i.PRD_IN_PATIENT_LIST_PRICE,
2015_AUG_PRD_OUT_PATIENT_LIST_PRICE=i.PRD_OUT_PATIENT_LIST_PRICE
FROM (
SELECT PRODUCTID,PRD_UNIT_PRICE,PRD_SELLING_PRICE,PRD_IN_PATIENT_LIST_PRICE,PRD_OUT_PATIENT_LIST_PRICE
FROM t_product_catalog
LEFT JOIN T_adjust ON IAJ_PRODUCTID=PRODUCTID AND IAJ_ADJNO IS NULL
WHERE PRODUCTID>1 AND (DATE(IAJ_DATE) = '2015-01-01')
GROUP BY IAJ_PRODUCTID
) AS i
WHERE i.PRODUCTID = t_prd_cost_compare.PRODUCTID
I get error like this
Error Code: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM (
SELECT PRODUCTID,PRD_UNIT_PRICE,PRD_SELLING_PRICE,PRD_IN_PATIENT_LIST_PRI' at line 7
I done checked the select statement is correct, but I still get error!
Any idea?
Issue solved, here is the solution

I have two DBs- RATINGSAPP and MIGRATIONDATA.
I want to update a table in RATINGSAPP with some values in a table in MIGRATIONDATA. I am trying to run this query:
update r set internal_id = m.internal_id from ratingsapp.hotel03 as r
inner join migrationdata.migration as m on r.hotel_id = m.restaurant_id
This gives me error:
You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right syntax to use near
'from ratingsapp.hotel03 as r inner join migrationdata.migration as m on r.hotel_' at line 1
But a similar select query works for me and gives proper results.
select r.hotel_id, m.internal_id from ratingsapp.hotel03 as r
inner join migrationdata.migration as m on r.hotel_id = m.restaurant_id
What I am doing wrong in the update query?
The correct MySQL syntax is:
update ratingsapp.hotel03 r inner join
migrationdata.migration as m
on r.hotel_id = m.restaurant_id
set internal_id = m.internal_id ;
There is no from clause in a MySQL update. You are using SQL Server/Postgres syntax.
UPDATE table1 SET announcer = ( SELECT memberid
FROM ( table1
JOIN users ON table2.username = table1.announcer
) AS a
WHERE a.username = table1.announcer )
#1064 - You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server
version for the right syntax to use
near 'a where
a.username=table1.announcer)'
at line 1
Try:
UPDATE announcements a
SET announcer =
(SELECT memberid
FROM users u
WHERE u.username = a.announcer)
You can also do the JOIN in the UPDATE
UPDATE announcements JOIN users
SET announcements.announcer=users.memberid
WHERE announcements.username=users.username;
Note: For safty reasons (until your sure announcers get copied over right) I'd instead create a new column, say announcerNew then
UPDATE announcements JOIN users
SET announcements.announcerNew=users.memberid
WHERE announcements.username=users.username;
