I've created this temporal table in my store procedure, as you can see I have more than 1 records for the same ID:
#tmpTableResults
TmpInstallerID TmpConfirmDate TmpConfirmLocalTime
============== ============== ===================
173 2011-11-08 11:45:50

That is the result of the query to create #tmpTableResults
DECLARE #tmpTableResults TABLE
(
TmpInstallerID int,
TmpConfirmDate date,
TmpConfirmLocalTime time
)
DECLARE #tmpTableQuery VarChar(800)

INSERT INTO #tmpTableResults EXEC(#tmpTableQuery)
I'm creating another query to get data from another table and only the first record from the temporal table for the same INSTALLERSYSID
SELECT RoutingGroup.SDESCRIPTION, FxWorkorder.INSTALLERSYSID, FxWorkOrder.JOBSTATUS, Install.FOXTELCODE,
install.NAME, FxWorkOrder.ScheduledDate,

group by RoutingGroup.SDESCRIPTION,FxWorkOrder.INSTALLERSYSID, FxWorkOrder.JOBSTATUS, Install.FOXTELCODE,install.NAME, FxWorkOrder.ScheduledDate,FxWorkOrder.WORKAREAGROUPSYSID
When I tried to save the sp I got the error
"Only one expression can be specified in the select list when the subquery is not introduced with EXISTS."
I can't see why I got this error. But if I run the query in sql that works. Can someone see the error?
I don't know how your second query works for you ‘in sql’ (where is that supposed to be? do you mean SSMS = SQL Server Management Studio?), but I'm sure it cannot possibly work in any version of SQL Server that exists at the moment. It's because of this subquery in the SELECT list:
(select TmpInstallerID, TmpConfirmDate, TmpConfirmLocalTime from #tmpTableResults where TmpInstallerID = FxWorkorder.INSTALLERSYSID)
The thing is, every expression in the SELECT clause should be scalar, but this subquery returns a row of more than one value. Even if it's only one row, it is illegal there, because it returns several columns. The subquery in that context should return no more than one value, i.e. it should be one column and the result produced should contain either no rows or just one.
You could try this query instead (although I'm not entirely sure without knowing more details about your schema):
SELECT
RoutingGroup.SDESCRIPTION,
FxWorkorder.INSTALLERSYSID,
FxWorkOrder.JOBSTATUS,
Install.FOXTELCODE,
install.NAME, FxWorkOrder.ScheduledDate,
count(*) as TotalJobs, COUNT(CONFIRMDATE) as ConfirmedJobs,
tmp.TmpInstallerID,
tmp.TmpConfirmDate,
tmp.TmpConfirmLocalTime
from FxWorkorder
join install on fxworkorder.INSTALLERSYSID = install.sysid
join RouteGroupWorkarea on FxWorkOrder.WORKAREAGROUPSYSID = RouteGroupWorkarea.IWORKAREA_ID
join RoutingGroup on RouteGroupWorkarea.IRG_ID = RoutingGroup.IRG_IDENTITY
join #tmpTableResults tmp ON tmp.TmpInstallerID = FxWorkorder.INSTALLERSYSID
where FxWorkorder.SCHEDULEDDATE > = #StartDate
and FxWorkorder.SCHEDULEDDATE <= #EndDate
and FxWorkOrder.Jobstatus <> 'Unassign'
and FxWorkOrder.Jobstatus <> 'Route'
and Install.FOXTELCODE <> ''
group by
RoutingGroup.SDESCRIPTION,
FxWorkOrder.INSTALLERSYSID,
FxWorkOrder.JOBSTATUS,
Install.FOXTELCODE,install.NAME,
FxWorkOrder.ScheduledDate,
FxWorkOrder.WORKAREAGROUPSYSID
tmp.TmpInstallerID,
tmp.TmpConfirmDate,
tmp.TmpConfirmLocalTime
That is, I added one more join, the one to #tmpTableResults, as well as added the columns you were trying to pull to the SELECT clause and to the GROUP BY clause.
Also, if I were you I would consider using short aliases for tables, like this:
SELECT
…
wo.INSTALLERSYSID,
wo.JOBSTATUS,
…
from FxWorkorder wo
join …
That might make your queries more readable.

I have a sql query (below) to insert records into a database. The goal is to insert only new / unique entries in the database. So it will insert the row if the row doesn't already exist in the entire database. I would like to have it evaluate that row against ONLY the rows that have the symbol in the instrumentSymbol, rather than evaluating against every row in the entire database.
I am running into this syntax error which I have pinpointed to be due to the use of an alias in line SELECT 1 FROM instrumentsHistory WHERE instrumentSymbol = 'ZYME' AS f
This query works fine if removing the WHERE instrumentSymbol = {SYMBOL} conditional, but I need to this to refine the set of records the query compares itself to (thus reducing time to complete task.
I have looked through the documentation which leads me to believe there is nothing wrong with this query. Can someone pls point me in the right direction?
The Error:
(sqlite3.OperationalError) near "AS": syntax error
[SQL: INSERT INTO instrumentsHistory (datetime, instrumentSymbol, observation, observationColName)

This code:
WHERE NOT EXISTS (SELECT 1 FROM instrumentsHistory WHERE instrumentSymbol = 'ZYME' AS f
WHERE t.datetime = f.datetime
has multiple errors. There are two WHERE clauses in a row. And as is being used in a WHERE clause. I am guessing this is a copy-and-past error, but it is unclear what you intend.
I came across this -
Using ALIAS column in WHERE recently and I understand why the WHERE clause is giving me an error but I can't seem to figure out any other way to write my nested query. The SELECT sub-query runs completely fine by itself.
The error is as follows:
Error Code: 1054. Unknown column 'actual_start_time' in 'IN/ALL/ANY subquery'
Table Structure:
Students: student_id student_name login_time logout_time
Tests: test_id test_start_time test_end_time
TestStats: test_id student_id test_duration
UPDATE test_stats
SET test_duration = datediff(hour, actual_start_time - actual_end_time)
WHERE (actual_start_time, actual_end_time)
IN (
SELECT
CASE
WHEN (s.login_time > t.test_start_time) THEN s.login_time
ELSE t.test_start_time
END AS actual_start_time,
CASE
WHEN (s.logout_time < t.test_end_time) THEN s.logout_time
ELSE t.test_end_time
END AS actual_end_time
FROM tests AS t, students AS s, test_stats AS ts
WHERE t.test_id = ts.test_id and s.student_id = ts.student_id);
This appears to be what you want:
UPDATE test_stats ts JOIN
tests t
ON t.test_id = ts.test_id JOIN
students s
ON s.student_id = ts.student_id
SET test_duration = timestampdiff(hour,
GREATEST(s.login_time, t.test_start_time),
LEAST(s.logout_time, t.test_end_time)
);
Hello I have this query that i am trying to execute and i keep getting this error "Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.", Kindly help please.
DECLARE #NUMCOUNT BIT
Select #NUMCOUNT = (SELECT
CASE WHEN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ('A')
) IN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ( 'A','C') ) THEN 1 else 0 END AS NUMCOUNT1
FROM R5REQUISLINES JOIN
R5REQUISITIONS ON R5REQUISLINES.RQL_REQ = R5REQUISITIONS.REQ_CODE
GROUP BY R5REQUISLINES.RQL_REQ, R5REQUISITIONS.REQ_CODE,R5REQUISLINES.RQL_STATUS
)
IF #NUMCOUNT = '1'
begin
UPDATE R5REQUISITIONS
SET R5REQUISITIONS.REQ_STATUS = 'CP'
end
Ok, it sounds like what you actually want to do is update R5REQUISITIONS when there is no RQL_STATUS = 'C' in R5REQUISLINES, since you said you want to count the records where the RQL_STATUS is A and where it's A or C, and then do the update if the counts are the same.. You can greatly simplify this task with the following query:
UPDATE r5
SET r5.REQ_STATUS = 'CP'
FROM R5REQUISITIONS r5
WHERE NOT EXISTS (SELECT 1 FROM R5REQUISLINES r5q WHERE r5q.RQL_REQ = r5.REQ_CODE AND r5q.RQL_STATUS = 'C')
Your 'SELECT CASE' is returning more than 1 record, so it can't be assigned to #NUMBER. Either fix the sub-query to only return the record your looking for or hack it to return only 1 with a 'LIMIT 1' qualification.
I don't know what your data looks like so I can't tell you why your case subquery returns more records than you think it should.
Try running this and see what it returns, that will probably tell you wall you need to know:
SELECT
CASE WHEN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ('A')
) IN
(SELECT COUNT(R5REQUISLINES.RQL_REQ)
WHERE R5REQUISLINES.RQL_STATUS IN ( 'A','C')
)
THEN 1
ELSE 0
END AS NUMCOUNT1
FROM R5REQUISLINES JOIN
R5REQUISITIONS ON R5REQUISLINES.RQL_REQ = R5REQUISITIONS.REQ_CODE
GROUP BY R5REQUISLINES.RQL_REQ, R5REQUISITIONS.REQ_CODE,R5REQUISLINES.RQL_STATUS
If there is more than 1 row returned, that's where your problem is.
I have a transport planner written in PHP and MySQL,
To get the task rules per day, I use the following query:
SELECT planning.*,
planning_dagen.planning_id,
planning_dagen.dagen,
planning_dagen.data_import,
routenummer_wijzigingen.routenummer AS temp_routenummer
FROM planning
LEFT JOIN planning_dagen
USING (planning_id)
LEFT JOIN routenummer_wijzigingen
USING (planning_id)
WHERE :datum >= planning.datum
AND :datum <= geldig_tot
AND (frequentie = 'dagelijks' AND dayofweek(:datum) = planning_dagen.dagen
OR (frequentie = 'eenmalig' AND date(:datum) = planning.datum)
OR (frequentie = 'wekelijks' AND 0 = (abs(datediff(:datum, planning.datum)) % 7))
OR (frequentie = 'twee-wekelijks' AND 0 = (abs(datediff(:datum, planning.datum)) % 14))
OR (frequentie = 'maandelijks'
AND ceil(dayofmonth(:datum)/7) = ceil(dayofmonth(planning.datum)/7)
AND dayofweek(:datum) = dayofweek(planning.datum)))
AND dayofweek(:datum) <> '1'
AND dayofweek(:datum) <> '7'
In the planning table there is a column called routenummer (routenumber) which is used in most conditions (standard routenumber).
But as you can see I have also a routenummer_wijzigingen table which is used to give a task a different routenumber for certain day.
For example I have a task which returns every tuesday and wednesday and has routenumber 10. But on tuesday 2015-02-03 I need this task done by routenumber 9.
So I insert a rule in the routenummer_wijzigingen table which has the following columns:
routenummer_wijzigingen_id
planning_id
routenummer
datum
So when a date is selected and that date and planning_id exists in the routenummer_wijzigingen table, it has to take the routenumber from the routenummer_wijzigingen table instead of the planning table.
How can I achieve this?
You should modify join condition with routenummer_wijzigingen table (including datum). Then you should use CASE in your SELECT clause to decide which routenummer to choose.
SELECT planning.*,
planning_dagen.planning_id,
planning_dagen.dagen,
planning_dagen.data_import,
CASE
WHEN routenummer_wijzigingen.routenummer is not NULL
THEN routenummer_wijzigingen.routenummer
ELSE planning.routenummer
END AS temp_routenummer
FROM planning
...
LEFT JOIN routenummer_wijzigingen rw on
planning.planning_id=rw.planning_id and rw.datum=...
I have multiple update statements in a stored procedure (as shown below).
Question is I am trying to combine them into one UPDATE statement as there is a performance issue (takes longer to execute stored procedure). I tried putting columns (such as PONUMBER, VENDORID etc) in a single update statement but it is throwing errors.
Please suggest.
UPDATE rptMaster SET PONUMBER = (select top 1 poMaster.PONUMBER from poMaster where poMaster.ITEMNMBR =rptMaster.ITEMNMBR and
poMaster.UnCommited > 0)
UPDATE rptMaster SET VENDORID = (select top 1 poMaster.VENDORID from poMaster where poMaster.ITEMNMBR =rptMaster.ITEMNMBR and
poMaster.UnCommited > 0)
UPDATE rptMaster SET DUEDATE = (select top 1 poMaster.REQDATE from poMaster where poMaster.ITEMNMBR =rptMaster.ITEMNMBR and
poMaster.UnCommited > 0)
UPDATE rptMaster SET POQTYORDER = (select top 1 (poMaster.QTYORDER / rptMaster.UOMQTY) from poMaster where poMaster.ITEMNMBR =rptMaster.ITEMNMBR and
poMaster.UnCommited > 0)
Mine is similar to polkduran's:
WITH PO AS (
SELECT PONUMBER
, VENDORID
, REQDATE
, QTYORDER
, ITEMNMBR
, ROW_NUMBER() OVER (PARTITION BY ITEMNMBR ORDER BY ??) as RN
FROM poMaster
WHERE UnCommited > 0
)
UPDATE rptMaster
SET PONUMBER = po.PONUMBER
, VENDORID = po.VENDORID
, DUEDATE = po.REQDATE
, POQTYORDER = po.QTYORDER / rptMaster.UOMQTY
FROM rptMaster
JOIN PO
ON PO.ITEMNMBR = rptMaster.ITEMNMBR
and PO.RN = 1
I'm using a Common Table Expression (CTE) to assign a row number to each poMaster record, with the records for each value of ITEMNMBR numbered separately. This allows us to pick to the first record for each ITEMNBR in our JOIN, later, similar to the way you were using Top 1 in your subqueries.
Please note, though: because you didn't indicate how you wanted to select the Top 1 record in your query, I had to leave the ORDER BY clause in the CTE unspecified. (I put ?? in as a placeholder.) You need to specify one or more sort fields in place of the ?? so it knows how to sort and number the records.
You can make an update using a join clause:
update rpt
set
PONUMBER = po.PONUMBER,
VENDORID = po.VENDORID,
DUEDATE = po.REQDATE,
POQTYORDER = (po.QTYORDER / rpt.UOMQTY)
from rptMaster rpt
inner join poMaster po
on po.ITEMNMBR = rpt.ITEMNMBR
where po.UnCommited > 0
I don't have a way to test it right now but that might work.
