I have 2 tables. I need to update all rows of table 1 with the values in specific columns from table 2. They have the same structure.
UPDATE #TempTable
SET [MyColumn] =
(
SELECT [MyColumn]
FROM
[udf_AggregateIDs] (#YearId) AS [af]
INNER JOIN [MyForm] ON
(
[af].[FormID] = [MyForm].[FormID] AND
[af].[FormID] = #MyFormId
)
WHERE [Description] = [MyForm].[Description]
)
I get an error saying Subquery returned more than 1 value. I only added the where clause in because i thought sql is struggling to match the rows, but both tables have the same rows.
It should return multiple values because i'm trying to copy across all rows for MyColumn from the one table to the other.
Ideas?
is Description unique ?
select [Description], count(*) from [MyForm] group by [Description] having count(*)>1
You don't need a sub query..just join the tables..
same type of question has been answered here. Hope it helps.
Have to guess here because your query isn't self-documenting. Does MyColumn come from the function? Does #TempTable have a description column? Who knows, because you didn't prefix them with an alias? Try this. You may have to adjust since you know your schema and we don't.
UPDATE t
SET [MyColumn] = func.MyColumn -- have to guess here
FROM dbo.[udf_AggregateIDs] (#YearId) AS func
INNER JOIN dbo.MyForm AS f
ON func.FormID = f.FormID
INNER JOIN #TempTable AS t
ON t.Description = f.Description -- guessing here also
WHERE f.FormID = #MyFormID;

Adding back some original info for historical purposes as I thought simplifying would help but it didn't. We have this stored procedure, in this part it is selecting records from table A (calldetail_reporting_agents) and doing a left join on table B (Intx_Participant). Apparently there are duplicate rows in table B being pulled that we DON'T want. Is there any easy way to change this up to only pick the first match on table B? Or will I need to rewrite the whole thing?
SELECT 'Agent Calls' AS CallType,
CallDate,
CallTime,
RemoteNumber,
DialedNumber,
RemoteName,
LocalUserId,

WHERE DialedNumber IN ( SELECT DialedNumber
FROM #DialedNumbers )
AND ConnectedDate BETWEEN #LocStartDate AND #LocEndDate
AND (#LocQueue IS NULL OR AssignedWorkGroup = #LocQueue)
Simpler version: how to change below to select only first matching row from table B:
SELECT columnA, columnB FROM TableA LEFT JOIN TableB ON someColumn
I changed to this per the first answer and all data seems to look exactly as expected now. Thank you to everyone for the quick and attentive help.

You can try to OUTER APPLY a subquery getting only one matching row.
...
FROM calldetail_reporting_agents
OUTER APPLY (SELECT TOP 1
*
FROM intx_Participant ip
WHERE ip.callidkey = calldetail_reporting_agents.callid) intx_participant
WHERE ...
You should add an ORDER BY in the subquery. Otherwise it isn't deterministic which row is taken as the first. Or maybe that's not an issue.
I am trying to insert only those records into #AltDealNames table for which DealName exists in #DistDeal table but not in #AltDealNames table. For this I am trying not exists clause. But it is not working as expected. Query is simply dumping records into #AltDealNames table.
insert into #AltDealNames
select d.DealName, d.ManagerScrubbed, d.BbgDealName, t.TrancheName, t.StreetCusip, t.ISIN, t.BbgTrancheName
from metric..Deal d join metric..Tranche t on d.DealName = t.DealName
where not exists(select 1 from #DistDeal dd join #AltDealNames ad on ad.DealName = dd.DealName)
Please help me to know if I am doing something wrong while building query.
If I understand correctly, you want an exists clause for #DistDeal and a not exists for #AltDealNames:
insert into #AltDealNames
select d.DealName, d.ManagerScrubbed, d.BbgDealName, t.TrancheName,
t.StreetCusip, t.ISIN, t.BbgTrancheName
from metric..Deal d join
metric..Tranche t
on d.DealName = t.DealName
where exists (select 1 from #DistDeal dd where dd.DealName = d.DealName) and
not exists (select 1 from #AltDealNames ad on ad.DealName = dd.DealName);
Note: when using insert, you should always include the list of column names.
Depending on how the optimizer sets up the actual physical query, the "where not exists" clause might run first, before anything is inserted by this query. Ie., it would only filter on values in #AltDealNames that were there from a previous query.
If you're trying to avoid inserting DealName values that are in #DistDeal, then maybe you want:
insert into #AltDealNames
select d.DealName, d.ManagerScrubbed, d.BbgDealName, t.TrancheName,
t.StreetCusip, t.ISIN, t.BbgTrancheName
from metric..Deal d
join metric..Tranche t on d.DealName = t.DealName
where not exists(select 1 from #DistDeal dd
where d.DealName = dd.DealName) -- Changed line
I am writing an Update trigger and am struggling with the Update statement:
The statement is as below:
UPDATE ARGUS_APP.CMN_REG_REPORTS CARR
SET CARR.DATE_SUBMITTED =
(
SELECT To_Date(M.ACKNOWLEDGMENTHEADER.MESSAGEDATE,'YYYYMMDDHH24MISS') Messagedate
FROM esm_owner.MESSAGES M
WHERE M.ACKNOWLEDGMENTHEADER.MESSAGESENDERIDENTIFIER='PMDA'
)
WHERE CARR.DATE_SUBMITTED =
(
SELECT CARR.DATE_SUBMITTED
FROM esm_owner.safetyreport sr,esm_owner.MESSAGES M,ARGUS_APP.CMN_REG_REPORTS CARR
WHERE sr.report_id=CARR.esm_report_id
AND M.msg_id = sr.msg_id
AND M.ACKNOWLEDGMENTHEADER.MESSAGESENDERIDENTIFIER='PMDA'
)
I get ORA:01427 everytime.
The Table structure is as below:
I have 3 tables
ARGUS_APP.CMN_REG_REPORTS CARR .............having the columns DATE_SUBMITTED(which I want to update) and esm_report_id which joins with the report_id of safety report
ESM_OWNER.SAFETYREPORT SR............having the columns report_id and MSG_ID(joined with the msg_id of the MESSAGES table)
MESSAGES M ..........having the columns MSG_ID and ACKNOWLEDGMENTHEADER.MESSAGESENDERIDENTIFIER
Please help me resolve this.
I'm going to take a wild stab and guess that this is what you are after. They key feature is correlating the subselects with the update (the carr in the subselects refer to the table in the outer statement).
Update
argus_app.cmn_reg_reports carr
set
carr.date_submitted = (
Select
To_Date(m.AcknowledgmentHeader.MessageDate, 'YYYYMMDDHH24MISS') Messagedate
from
esm_owner.Messages m
inner join
esm_owner.SafetyReport sr
on m.msg_id = sr.msg_id
where
carr.esm_report_id = sr.report_id And
m.AcknowledgmentHeader.MessageSenderIdentifier = 'PMDA'
)
Where
Exists (
Select
'x'
From
esm_owner.Messages m
Inner Join
esm_owner.SafetyReport sr
on m.msg_id = sr.msg_id
Where
carr.esm_report_id = sr.report_id and
m.AcknowledgmentHeader.MessageSenderIdentifier = 'PMDA'
)
Here's an example showing the basic principle works:
Example Fiddle
It looks like one of your subqueries is probably returning more than one row of data. You could perhaps check this by running each on its own.
If you want the update to apply to them all, change the
... = (SELECT...
to
... IN (SELECT ...
I have the following SQL statement to simply update the #temp temp table with the latest package version number in our Sybase 15 database.
UPDATE t
SET versionId = l.latestVersion
FROM #temp t INNER JOIN (SELECT gp.packageId
, MAX(gp.versionId) latestVersion
FROM Group_Packages gp
WHERE gp.groupId IN (SELECT groupId
FROM User_Group
WHERE userXpId = 'someUser')
GROUP BY gp.packageId) l
ON t.packageId = l.packageId
To me (mainly Oracle & SQL Server experience more than Sybase) there is little wrong with this statement. However, Sybase throws an exception:
You cannot use a derived table in the FROM clause of an UPDATE or DELETE statement.
Now, I don't get what the problem is here. I assume it is because of the aggregation / GROUP BY being used. Of course, I could put the sub query in a temp table and join on it but I really want to know what the 'correct' method should be and what the hell is wrong.
Any ideas or guidance would be much appreciated.
It seems that SYBASE doesn't support nested queries in UPDATE FROM class. Similar problem
Try to use this:
UPDATE #temp
SET versionId = (SELECT MAX(gp.versionId) latestVersion
FROM Group_Packages gp
WHERE gp.packageId=#temp.packageId
and
gp.groupId IN (SELECT groupId
FROM User_Group
WHERE userXpId = 'someUser')
)
And also what if l.latestVersion is NULL? Do you want update #temp with null ? if not then add WHERE:
WHERE (SELECT MAX(gp.versionId)
....
) is not null
I guess this is a limitation of Sybase (not allowing derived tables) in the FROM clause of the UPDATE. Perhaps you can rewrite like this:
UPDATE t
SET t.versionId = l.versionId
FROM #temp t
INNER JOIN
Group_Packages l
ON t.packageId = l.packageId
WHERE
l.groupId IN ( SELECT groupId
FROM User_Group
WHERE userXpId = 'someUser')
AND
l.versionId =
( SELECT MAX(gp.versionId)
FROM Group_Packages gp
WHERE gp.groupId IN ( SELECT groupId
FROM User_Group
WHERE userXpId = 'someUser')
AND gp.packageId = l.packageId
) ;
Your table alias for #temp is called "t" and your original table is called "t".
My guess is that this is the problem.
I think you want to start with:
update #temp
Does this syntax work in Sybase?
update dstTable T
set (T.field1, T.field2, T.field3) =
(select S.value1, S.value2, S.value3
from srcTable S
where S.key = T.Key);
I believe the correlated subquery can be as complicated as you like (including using CTE. etc). It just has to project the right number (and type) of values.
I have this query and it works well, the question is if there is a way to have the query NULL the column value if it doesn't exist in the table?
UPDATE PRD_WOCNT
SET c1 = (
SELECT WO_CNT.RATE FROM WO_CNT
WHERE WO_CNT.CNT = PRD_WOCNT.c1
)
WHERE EXISTS (
SELECT WO_CNT.CNT FROM WO_CNT
WHERE WO_CNT.CNT = PRD_WOCNT.c1
)
Right it uses a second table to update the main table values of sales codes into their commission rates. but sometimes a sales code is entered that doesn't exist in the table so it adds the sales code as a dollar value and makes the added total wrong.
I don't know too much PHP and trying not to bother with it if I can simply alter the query... it's a stab in the dark, have a feeling I'll need to do this on the PHP side but have no idea how I can have my query tell the php it doesn't exist.
UPDATE a
SET c1 = WO_CNT.RATE
FROM PRD_WOCNT a
LEFT JOIN WO_CNT b
ON b.CNT = a.c1
I havn't executed. I think it will work. Try this query:
UPDATE PRD_WOCNT SET c1 = CASE
WHEN EXISTS (
SELECT WO_CNT.CNT FROM WO_CNT
WHERE WO_CNT.CNT = PRD_WOCNT.c1
)
THEN (
SELECT WO_CNT.RATE FROM WO_CNT
WHERE WO_CNT.CNT = PRD_WOCNT.c1
)
ELSE NULL
END
