I am attempting to update a column from one table with a select query.
It runs and updates the entire type_ column as religious (text field).
I am trying to only update the rows where the religious geometry intersects the parcel geometry.
update wash_parcels_final
set type_ = t.religious
from (select wash_worship.religious
from wash_parcels_final
join wash_worship
on st_intersects(wash_worship.geom, wash_parcels_final.geom)) t
I think this is what you want:
update wash_parcels_final
set type_ = ww.religious
from wash_worship ww
where st_intersects(ww.geom, wash_parcels_final.geom);
I Use PgAdmin4 and last version of PostgreSQL and this query works for me:
update public."UserPoints"
set "AvailablePoints" = up."AvailablePoints" + tc."CLV"
from public."UserPoints" up join public."TEMPCLV" tc on up."UserId" = tc."CUSTOMER_NUMBER"
Hope help someone else!

SQL query (PostgreSQL) looks like that:
UPDATE a
SET "PropertyAddress" = COALESCE(a."PropertyAddress", b."PropertyAddress")
FROM "NashvilleHousingData" a
INNER JOIN "NashvilleHousingData" b
ON a."ParcelID" = b."ParcelID"
AND a."UniqueID" <> b."UniqueID"
WHERE a."PropertyAddress" IS NULL;
And the error is relation "a" does not exist
I tried other advices about the notion in the code public or scheme, but it still doesn't work. Please, help
This is not how Postgres handles updates with more than one table. You don't repeat the table in the from clause:
UPDATE "NashvilleHousingData" nhd
SET "PropertyAddress" = COALESCE(nhd."PropertyAddress", nhd2."PropertyAddress")
FROM "NashvilleHousingData" nhd2
WHERE nhd2."ParcelID" = nhd."ParcelID" AND
nhd2."UniqueID" <> nhd."UniqueID"
WHERE nhd."PropertyAddress" IS NULL;
Also, the COALESCE() is superfluous because the value is known to be NULL:
SET "PropertyAddress" = nhd2."PropertyAddress"
I have this simple merge statement but it failed when running.
Any advice is appreciated.
MERGE INTO HP.SampleAll as A
USING (
select ALIGNED
from HP.Sample2
) as B
ON (A.md_nbr = B.md_nbr)
WHEN MATCHED THEN UPDATE
SET ALIGNED = A.ALIGNED ;
Error 3810 says that Column does not exist.
md_nbr dont exist in your subquery B - as you don't select it.
Maybe a solution is:
MERGE INTO HP.SampleAll as A
USING (
select ALIGNED, md_nbr
from HP.Sample2
) as B
ON (A.md_nbr = B.md_nbr)
WHEN MATCHED THEN UPDATE
SET ALIGNED = A.ALIGNED ;
or just USING HP.Sample2 as B
I wish to update a table using, but need to use another table to get the correct field. The new information is not taken from another field from another table.
The following SQL statement returns the correct information:
SELECT PURCHASEHEADER.ORDERNOTES
FROM PURCHASEHEADER, ASSEMBLYLINESOURCE
WHERE ASSEMBLYLINESOURCE.HEADERSYSUNIQUEID = 72637001
AND PURCHASEHEADER.ORDERNUMBER = ASSEMBLYLINESOURCE.PURCHASEORDERNUMBER
I have tried the following:
UPDATE PURCHASEHEADER SET PURCHASEHEADER.ORDERNOTES = 'Updated'
WHERE EXISTS (
SELECT 1 FROM ASSEMBLYLINESOURCE
WHERE PURCHASEHEADER.ORDERNUMBER = ASSEMBLYLINESOURCE.PURCHASEORDERNUMBER
) AND ASSEMBLYLINESOURCE.HEADERSYSUNIQUEID = 72637001
An error is returned saying: " ...Column Unknown ASSEMBLYLINESOURCE.HEADERSYSUNIQUEID..." but it does exist as it works in the first query.
I have seen similar posts from Mark Rotteveel dated July 2017, but still can't get it to work.
There is an issue with your closing bracket. Try this, it worked for me.
UPDATE PURCHASEHEADER set PURCHASEHEADER.ORDERNOTES = 'Updated'
WHERE EXISTS (SELECT 1 FROM ASSEMBLYLINESOURCE WHERE
PURCHASEHEADER.ORDERNUMBER = ASSEMBLYLINESOURCE.PURCHASEORDERNUMBER AND
ASSEMBLYLINESOURCE.HEADERSYSUNIQUEID = 72637001)
The other day,I thought I found a very elegant way to update part of a set of cells. This is what I came up with :
Update mytable
Set ExternalLink = REPLACE (ExternalLink, R.UniqueID, R.ParentUniqueID)
From (
Select u.UniqueID, u.ParentUniqueID, RIGHT (mt.ExternalLink, 7) as EL
From uniqueidtable u
Join mytable mt
On EL = u.ParentUniqueID
Where mt.ExternalLink Like '%stringinurl%' ) R
I believe I got the idea from a stack question, but I can't find it in my history.
I can't seem to get more than one cell updated, even though the subquery returns several rows when tested alone. What's wrong with this and how can I tweak it to update multiple cells at a time?
Thank you for your help.
Okay, I came up with an answer. I'm not sure why a Table Expression did not work in this case, but here's what I came up with:
UPDATE mytable
SET ExternalLink = REPLACE(Ta.ExternalLink, T.ParentUniqueID, T.UniqueID)
FROM mytable Ta
JOIN UniqueIDtable
ON RIGHT(Ta.ExternalLink, 7) = T.ParentUniqueID
WHERE ExternalLink LIKE '%stringinurl%' AND ISNUMERIC(RIGHT(Ta.ExternalLink, 7)) = '1';
It seems I was just messing up the placement of the ID and parent ID in the replace. I also didn't count on the end of the URL string in the ExternalLink column to be anything but a numeric value, so that came up with some issues as well. It seems to be working for me now, so I've got that going for me.
I have query
UPDATE THD
SET RepostFlag = 'Y'
,RunListNoRetroPolicyPrepay = ?
,RetroObject = ?
FROM TranHead AS THD
JOIN (
SELECT CustPolicyNo AS CustPolicyNo
,MIN(PremPeriod) AS PremPeriod
FROM TranHead
WHERE RepostFlag = 'Y'
AND PayoutTypeNo = ?
GROUP BY CustPolicyNo
) AS THDToBeReposted ON THD.CustPolicyNo = THDToBeReposted.CustPolicyNo
WHERE THD.RepostFlag = 'N'
AND THD.PremPeriod > THDToBeReposted.PremPeriod
fails in H2 with following message
Table "THD" not found;
I looked at http://www.h2database.com/html/grammar.html#table_expression to see if H2 supports selects in join. It appears it does. Maybe I am missing something when looking at the grammar, but it seems to me that the query should work in H2.
Anyone see what is wrong?
Thanks.
I don't believe FROM is allowed in the UPDATE syntax.
You can't update an alias, you need to have the table name specified.
Complementary to other answers, JOIN (just as FROM) is not allowed in UPDATE for H2. It would be allowed in a sub query.
Essentially, stick to the basic syntax:
UPDATE SomeTable as SomeAlias
SET SomeField = ?
WHERE (%GoWild%)
Whether or not you need the alias is up to your where clause.
