I am facing a strange behavior with a merge into statement in Oracle. Actually,few days ago, my statement used to work perfectly and the requested column is being updated. However, as of today I found out it is no longer updating the column. I am getting confused if this is environment related issue or a problem related the query it self. Can you advise please ?
Query :
merge into Currency_table CURR
using (
SELECT CURR.rowid as RID, M_SYSTEM
FROM Currency_table CURR, Trade_ext TRN_EXT, TradeGen TRN, CONTRACT CNT
WHERE CNT.M_REFERENCE= 123
AND CNT.M_REFERENCE = TRN.M_CONTRACT
AND TRN.M_NumB = TRN_EXT.M_C_REF
AND TRN_EXT.M_C_REF = CURR.M_NumBer
)T
on ( CURR.rowid = T.RID)
when matched then
update set CURR.MSYSTEM = 'S1' ;

I have a code block that has 7/8 with clauses(
sub-query refactoring) in queries. I'm looking on how to run this query as I'm getting 'sql compilation errors' when running these!, While I'm trying to run them I'm getting errors in snowflake. for eg:
with valid_Cars_Stock as (
select car_id
from vw_standard.agile_car_issue_dime
where car_stock_expiration_ts is null
and car_type_name in ('hatchback')
and car_id = 1102423975
)
, car_sale_hist as (
select vw.issue_id, vw.delivery_effective_ts, bm.car_id,
lag(bm.sprint_id) over (partition by vw.issue_id order by vw.delivery_effective_ts) as previous_stock_id
from valid_Cars_Stock i
join vw_standard.agile_car_fact vw on vw.car_id = bm.car_id
left join vw_standard.agile_board_stock_bridge b on b.board_stock_bridge_dim_key = vw.issue_board_sprint_bridge_dim_key
order by vw.car_stock_expiration_ts desc
)
,
So how to run this 2 queries separately or together! I'm new to sql aswell any help would be ideal
So lets just reformate that code as it stands:
with valid_Cars_Stock as (
select
car_id
from vw_standard.agile_car_issue_dime
where car_stock_expiration_ts is null
and car_type_name in ('hatchback')
and car_id = 1102423975
), car_sale_hist as (
select
vw.issue_id,
vw.delivery_effective_ts,
bm.car_id,
lag(bm.sprint_id) over (partition by vw.issue_id order by vw.delivery_effective_ts) as previous_stock_id
from valid_Cars_Stock i
join vw_standard.agile_car_fact vw
on vw.car_id = bm.car_id
left join vw_standard.agile_board_stock_bridge b
on b.board_stock_bridge_dim_key = vw.issue_board_sprint_bridge_dim_key
order by vw.car_stock_expiration_ts desc
),
There are clearly part of a larger block of code.
For an aside of CTE, you should 100% ignore anything anyone (including me) says about them. They are 2 things, a statical sugar, and they allow avoidance of repetition, thus the Common Table Expression name. Anyways, they CAN perform better than temp tables, AND they CAN perform worse than just repeating the say SQL many times in the same block. There is no one rule. Testing is the only way to find for you SQL what is "fastest" and it can and does change as updates/releases are made. So ignoring performance comments.
if I am trying to run a chain like this to debug it I alter the point I would like to stop normally like so:
with valid_Cars_Stock as (
select
car_id
from vw_standard.agile_car_issue_dime
where car_stock_expiration_ts is null
and car_type_name in ('hatchback')
and car_id = 1102423975
)--, car_sale_hist as (
select
vw.issue_id,
vw.delivery_effective_ts,
bm.car_id,
lag(bm.sprint_id) over (partition by vw.issue_id order by vw.delivery_effective_ts) as previous_stock_id
from valid_Cars_Stock i
join vw_standard.agile_car_fact vw
on vw.car_id = bm.car_id
left join vw_standard.agile_board_stock_bridge b
on b.board_stock_bridge_dim_key = vw.issue_board_sprint_bridge_dim_key
order by vw.car_stock_expiration_ts desc
;), NEXT_AWESOME_CTE_THAT_TOTALLY_MAKES_SENSE (
-- .....
and now the result of car_sale_hist will be returned. because we "completed" the CTE chain by not "starting another" and the ; stopped the this is all part of my SQL block.
Then once you have that steps working nicely, remove the semi-colon and end of line comments, and get of with value real value.
I've been working on this problem, researching what I could be doing wrong but I can't seem to find an answer or fault in the code that I've written. I'm currently extracting data from a MS SQL Server database, with a WHERE clause successfully filtering the results to what I want. I get roughly 4 rows per employee, and want to add together a value column. The moment I add the GROUP BY clause against the employee ID, and put a SUM against the value, I'm getting a number that is completely wrong. I suspect the SQL code is ignoring my WHERE clause.
Below is a small selection of data:
hr_empl_code hr_doll_paid
1 20.5
1 51.25
1 102.49
1 560
I expect that a GROUP BY and SUM clause would give me the value of 734.24. The value I'm given is 211461.12. Through troubleshooting, I added a COUNT(*) column to my query to work out how many lines it's running against, and it's giving a result of 1152, furthering reinforces my belief that it's ignoring my WHERE clause.
My SQL code is as below. Most of it has been generated by the front-end application that I'm running it from, so there is some additional code in there that I believe does assist the query.
SELECT DISTINCT
T000.hr_empl_code,
SUM(T175.hr_doll_paid)
FROM
hrtempnm T000,
qmvempms T001,
hrtmspay T166,
hrtpaytp T175,
hrtptype T177
WHERE 1 = 1
AND T000.hr_empl_code = T001.hr_empl_code
AND T001.hr_empl_code = T166.hr_empl_code
AND T001.hr_empl_code = T175.hr_empl_code
AND T001.hr_ploy_ment = T166.hr_ploy_ment
AND T001.hr_ploy_ment = T175.hr_ploy_ment
AND T175.hr_paym_code = T177.hr_paym_code
AND T166.hr_pyrl_code = 'f' AND T166.hr_paid_dati = 20180404
AND (T175.hr_paym_type = 'd' OR T175.hr_paym_type = 't')
GROUP BY T000.hr_empl_code
ORDER BY hr_empl_code
I'm really lost where it could be going wrong. I have stripped out the additional WHERE AND and brought it down to just T166.hr_empl_code = T175.hr_empl_code, but it doesn't make a different.
By no means am I any expert in SQL Server and queries, but I have decent grasp on the technology. Any help would be very appreciated!
Group by is not wrong, how you are using it is wrong.
SELECT
T000.hr_empl_code,
T.totpaid
FROM
hrtempnm T000
inner join (SELECT
hr_empl_code,
SUM(hr_doll_paid) as totPaid
FROM
hrtpaytp T175
where hr_paym_type = 'd' OR hr_paym_type = 't'
GROUP BY hr_empl_code
) T on t.hr_empl_code = T000.hr_empl_code
where exists
(select * from qmvempms T001,
hrtmspay T166,
hrtpaytp T175,
hrtptype T177
WHERE T000.hr_empl_code = T001.hr_empl_code
AND T001.hr_empl_code = T166.hr_empl_code
AND T001.hr_empl_code = T175.hr_empl_code
AND T001.hr_ploy_ment = T166.hr_ploy_ment
AND T001.hr_ploy_ment = T175.hr_ploy_ment
AND T175.hr_paym_code = T177.hr_paym_code
AND T166.hr_pyrl_code = 'f' AND T166.hr_paid_dati = 20180404
)
ORDER BY hr_empl_code
Note: It would be more clear if you have used joins instead of old style joining with where.
I'm writing a database and I simply want to update tblSchedule with the ItemNo from tblStock but I get an error when trying to run this:
Operation must be an updatable query
I can't seem to figure out why it's not working.
UPDATE [tblSchedule]
SET [tblSchedule].ItemNo =
(SELECT DISTINCT Item
FROM [tblStock], [tblSchedule]
WHERE [tblStock].Bookcode=[tblSchedule].[PartCode]
)`;
Any help would really be appreciated
You are missing a closing bracket in your SQL.
UPDATE [tblSchedule] Set
[tblSchedule].ItemNo = (
SELECT DISTINCT Item
FROM [tblStock], [tblSchedule -- Missing closing bracket
WHERE ((([tblStock].Bookcode)=[tblSchedule].[PartCode]))
)
Try closing the bracket on tblSchedule.
I do not have an Access database to test this on for you, though.
My guess is your inner SELECT is returning 2 records instead of one.
You can do this to validate.
SELECT Items.ItemNo, count(*) total
FROM
(
SELECT DISTINCT Sc.ItemNo, St.Item
FROM
[tblSchedule] Sc INNER JOIN
[tblStock] St ON Sc.PartCode = St.Bookcode
) as Items
GROUP BY Items.ItemNo
HAVING count(*) > 1;
Due to the simplicity of what I wanted I've gone down the Dlookup route which works successfully.
UPDATE [tblSchedule], [tblStock] SET [tblSchedule].ItemNo = DLookUp("Item","[tblStock]","[tblStock].Bookcode='" & [tblSchedule].[PartCode] & "'")
WHERE (([tblStock].[Bookcode]=[tblSchedule].[PartCode]));
It's probably not the best method but due to the small amount of records it updates (252) it works perfectly without any noticable time delay.
Thanks Again!

SELECT Distinct lu.ObjectID
FROM LAND_USE_EVW as lu
WHERE NOT EXISTS (SELECT LAND_USE_EVW.OBJECTID
FROM LAND_USE_EVW, MUNICIPALITIES_EVW
WHERE LAND_USE_EVW.Shape.STCentroid().STIntersects(MUNICIPALITIES_EVW.shape) = 1
)
I was trying to get a result that opposite of below
select LAND_USE_EVW.OBJECTID
from LAND_USE_EVW, MUNICIPALITIES_EVW
where LAND_USE_EVW.Shape.STCentroid().STIntersects(MUNICIPALITIES_EVW.shape) = 1
= 0 didn't work therefore I'm trying to come up with other idea.
But result shows nothing. No errors or warning.
found answer
WHERE NOT EXISTS (SELECT LAND_USE_EVW.OBJECTID
FROM LAND_USE_EVW, MUNICIPALITIES_EVW
removing LAND_USE_EVW from FROM LAND_USE_EVW solve the problem
trying to update a single column based on criteria. The rows that need to be updated are returned by the query
SELECT
it.objectid,
it.versionnumber,
it.itemnumber "Item Number",
it.itemtype,
itcovprem.basisofsettlement,
itcovprem.coverage "Coverage"
FROM
itemcoveragesandpremiums itcovprem,
items it,
policies pl
WHERE
pl.objectid = it.parentobjectid AND
pl.policytype in ('H','F') AND
it.objectid = itcovprem.itemobjectid AND
it.itemtype in ('SHOA','SHOB','SHOC','SHOD','SHOK','SHOL') and
it.versionnumber = itcovprem.itemversionnumber AND
((itcovprem.coverage like ('A - Dwg Bldg%')) or
(itcovprem.coverage like ('#42 - Repl Cost Plus%')) or
(itcovprem.coverage like ('#42 - Limited GRC%'))) and
it.effectivedate >= TO_DATE('01-JAN-2006', 'DD-MON-YYYY') and

itcovprem.basisofsettlement not in ('LGRC')
I've tried a few options to convert this to an update query, but no joy.
I get Error - line 3 - SQL command not properly ended when using
update itemcoveragesandpremiums
set basisofsettlement = 'LGRC'
from itemcoveragesandpremiums as itcovprem
inner join items as it
on it.objectid = itcovprem.itemobjectid and it.versionnumber = itcovprem.itemversionnumber
inner join policies as pl
on pl.objectid = it.parentobjectid
where [cut, rest of query was below]
I get Error - line 6 - missing right parenthesis when trying use an inline query
update
(
SELECT
itcovprem.basisofsettlement as OLD
FROM
itemcoveragesandpremiums as itcovprem inner join items as it on it.objectid = itcovprem.itemobjectid and it.versionnumber = itcovprem.itemversionnumber inner join policies AS pl on pl.objectid = it.parentobjectid
WHERE [query snipped]
) t
set t.old = 'LGRC'
Seems that SQL*Plus just wants to stop looking at the update before it gets to the meat of my select query. I'm not sure if I'm formatting it incorrectly or going at it from the wrong direction. Any advice?
In your first attempt, the error at line 3 is because update doesn't support a from or join clause. In your second attempt the immediate error at line 6 is because you're trying to alias a table with as itcovprem; but you can only use as for column aliases, not for table aliases. (The first attempt is trying to do that too, but it isn't getting as far as encountering that problem). But you can't generally update an inline-view with joins anyway, so it would still error with that - something like an ORA-01779.
You would need to do something like:
update itemcoveragesandpremiums
set basisofsettlement = 'LGRC'
where (itemobjectid, itemversionnumber, basisofsettlement, coverage) in (
select it.objectid,
it.versionnumber,
itcovprem.basisofsettlement,
itcovprem.coverage
from ...
)
Assuming that itemobjectid, itemversionnumber, basisofsettlement, coverage identifies a row sufficiently such that you don't risk updating anything you shouldn't. It might be safer to add a rowid to the select and use that for the update instead to avoid ambiguity:
update itemcoveragesandpremiums
set basisofsettlement = 'LGRC'
where rowid in (
select itcovprem.rowid as target_rowid
from ...
)
