I'm working on SSRS report builder that is using a dataset calling a SQL Server 2000 database.
The query is getting sums of a few different fields and is also pulling out all records that have to do with that client number. I want to get the sum of the sum but it is way over because of the detail rows. Basically what I want is the sum of the distinct sum column values.
=Sum(Fields!tot.Value, "table1_Group3")
I saw that you can get sums by the groups and I tried the expression above but it comes back with an error:
The Value expression for the textbox 'tot' has a scope parameter that is not
valid for an aggregate function...
table1_Group3 is the name of the group that holds the sum value in the report.
Any suggestions on how to get the distinct values to sum them in this report.
=Sum(Fields!tot.Value, "table1_Group3")
The code above will give you the sum of "tot" for all rows in the current "table1_Group3." This means that this expression only makes sense somewhere within table1_Group3. Otherwise, SSRS doesn't know which is the current instance of that group.
Sounds like you would like to sum this value across multiple groups, but only take one "tot" from each instance of the group. (Are you sure that all rows in that group will have the same "Tot?")
If tot is the total of other fields in your returned data, then simply add those up in your formula. This may have the added benefit of simplifying your SQL query as well.
Some other options that could work:
- Change your SQL query so that only one row per group gets the Tot field set.
- Use Embedded code in the report to keep a running total which is added to only once per group, such as in the group header.
(If upgrading to 2008R2 SSRS is an option, then the Lookup function could be used here, maybe even to look back at the same dataset.)
change the query/ dataset to sum(distinct tot) using the temp table on the sql server
I suppose you need to write sum(distinct columnName).

I want to group by two columns, however MS Access won't let me do it.
Here is the code I wrote:
SELECT
tbl_Produktion.Datum, tbl_Produktion.Schichtleiter,
tbl_Produktion.ProduktionsID, tbl_Produktion.Linie,
tbl_Produktion.Schicht, tbl_Produktion.Anzahl_Schichten_P,
tbl_Produktion.Schichtteam, tbl_Produktion.Von, tbl_Produktion.Bis,
tbl_Produktion.Pause, tbl_Produktion.Kunde, tbl_Produktion.TeileNr,
tbl_Produktion.FormNr, tbl_Produktion.LabyNr,
SUM(tbl_Produktion.Stueckzahl_Prod),
tbl_Produktion.Stueckzahl_Ausschuss, tbl_Produktion.Ausschussgrund,
tbl_Produktion.Kommentar, tbl_Produktion.StvSchichtleiter,
tbl_Produktion.Von2, tbl_Produktion.Bis2, tbl_Produktion.Pause2,
tbl_Produktion.Arbeiter3, tbl_Produktion.Von3, tbl_Produktion.Bis3,
tbl_Produktion.Pause3, tbl_Produktion.Arbeiter4,
tbl_Produktion.Von4, tbl_Produktion.Bis4, tbl_Produktion.Pause4,
tbl_Produktion.Leiharbeiter5, tbl_Produktion.Von5,
tbl_Produktion.Bis5, tbl_Produktion.Pause5,
tbl_Produktion.Leiharbeiter6, tbl_Produktion.Von6,
tbl_Produktion.Bis6, tbl_Produktion.Pause6, tbl_Produktion.Muster
FROM
tbl_Personal
INNER JOIN
tbl_Produktion ON tbl_Personal.PersID = tbl_Produktion.Schichtleiter
GROUP BY
tbl_Produktion.Datum, tbl_Produktion.Schichtleiter;
It works when I group it by all the columns, but not like this.
The error message say that the rest of the columns aren't part of the aggregation-function (translated from german to english as best as I could).
PS.: I also need the sum of "tbl_Produktion.Stueckzahl_Prod" therefore I tried using the SUM function (couldn't try it yet).
Have you tried something along these lines?
SELECT
tbl_Produktion.Datum, tbl_Produktion.Schichtleiter,
MAX(tbl_Produktion.ProduktionsID), MAX(tbl_Produktion.Linie),
MAX(tbl_Produktion.Schicht), MAX(tbl_Produktion.Anzahl_Schichten_P),
MAX(tbl_Produktion.Schichtteam), MAX(tbl_Produktion.Von), MAX(tbl_Produktion.Bis),
SUM(tbl_Produktion.Stueckzahl_Prod)
FROM
tbl_Personal
INNER JOIN
tbl_Produktion ON tbl_Personal.PersID = tbl_Produktion.Schichtleiter
GROUP BY
tbl_Produktion.Datum, tbl_Produktion.Schichtleiter;
I have used the MAX function for all the data except the two items you specify in the GROUP BY and the one where you desire the SUM. I took the liberty of leaving out mush of your data just to get started.
Using the MAX function turns out to be a convenient workaround when the data item is known to be unique within each group. We cannot know your data or your itent, so we cannot tell you whether MAX will yield the results you need.
If you use an aggregation function in the select clause, you must group by every column that you're selecting that's not an aggregation. If you don't want to do that for some reason (perhaps it changes the output of the aggregation in way that you don't intend) you either must think of an aggregate to use (pick a value. Average? Max? Min?) or just do two selects, one for the aggregate, and one for the non-aggregates. But, then, you have to decide how to get the non-aggregated fields that make sense for the aggregate (or show them all in a table, I suppose?)
I'm trying to produce the result shown in the "Desired Results" section (in SQL Server 2016) in my screenshot below, where the objections associated with each borrower number are in one column delimited by commas instead of separate rows.
I don't want to restructure my database - I just want to display the results as requested for a customer report. Thanks
I was able to use the STRING_AGG function which I didn't know existed to produce the results I need.
SELECT ht.Hearings_CaseID, Borrower_Number, STRING_AGG(Objection,',') AS Objection
FROM Hearings_Test ht INNER JOIN
Hearings_Objections_Test hot on ht.Hearings_CaseID = hot.Hearings_CaseID
GROUP BY
ht.Hearings_CaseID, Borrower_Number
How to write this expression in PowerBI
select distinct([date]),Temperature from Device47A8F where Temperature>25
Totally new to PowerBI. Is there any tool that can change the query from sql to PowerBI expression?
I have tried so many type of different type of expressions but getting error, Most of the time I am getting this:
The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.
Need help, Thanks.
After I posted my answer, wondered if your expected result is get only one date by temperature, In other words, without repeated dates in your result set.
A side note: select distinct([date]),Temperature from Device47A8F where Temperature>25 returns repeated dates since DISTINCT keyword evaluate distinct columns values specified in the SELECT statement, it doesn't return distinct values in a specific column even if you surround it with parenthesis.
Now what brings us here. What I can see in your error is that you are trying to use a table-valued (produces a table with multiple columns) expression in a measure which only accepts scalar-valued (calculate only one value).
Supposing you have a table like this:
Running your SQL query you will get the highlighted in yellow rows:
You can see 01/09/2016 date is repeated. If you want to create a measure you have to define what calculation you want to show for temperature. i.e, average, max or min etc.
In the below expression is being calculated the maximum temperature greater than 25 per date:
MaxTempGreaterThan25 =
CALCULATE ( MAX ( Device47A8F[Temperature] ), Device47A8F[Temperature] > 25 )
In this case the measure MaxTempGreaterThan25 is calculated per date.
If you don't want to produce a measure but a table. In the Power BI Tool bar select Modeling tab and click New Table icon.
Use this expression:
MyTemperatureTable =
FILTER ( Device47A8F, Device47A8F[Temperature] > 25 )
It should produce a new table named MyTemperatureTable like this:
I recommend you learn some basics about DAX, it is pretty different from SQL / T-SQL and there are things you can't do depending on your model and data.
Let me know if this helps.
You probably don't need to write any code if your objective is to show the result in a Power BI visual e.g. a table. Power BI naturally aggregates data if the datatype is numeric (e.g. Temperature).
I would just add a Table visual on a Report page and add the Date and Temperature columns to it. Then in Visualizations / Fields / Values I would click the little down-arrow on the Temperature field and set the Aggregation e.g. Maximum. Then in Visualizations / Fields / Filters I would click the little down-arrow on the Temperature field and set the Filter e.g. is greater than: 25
Hard-coded solutions are unlikely to survive the next question from your users e.g. "but what if I want to see Temperature > 24? Or 20? Or 30?"
I am writing reports using Report Builder 3, and I need some help with an sql query to get unique values.
Using the following sample data:
I need to be able to get one single value for feeBudRec returned for each feeRef. The value of each feeBudRec is always the same for each individual feeRef (eg for every data row for feeRef LR01 will have a feeBudRec of 1177).
The reason why I need to get a single feeBudRec value for each feeRef is that I need to be able to total the feeBudRec value for each feeRef in a feePin (eg for feePin LEE, I need to total the feeBudRec values for LR01 and PS01, which should be 1177 + 1957 to get a total of 3134; but if I don't have unique values for feeBudRec, it will add the values for each row, which would bring back a total of 11756 for the 8 LEE rows).
My experience with writing SQL queries is very limited, but from searching the internet, it looks like I'll need to put in a subquery into my SQL query in order to get a single unique feeBudRec figure for each feeRef, and that a subquery that gets a minimum feeBudRec value for each feeRef should work for me.
Based on examples I've found, I think the following subquery should work:
SELECT a.feeRef, a.feeBudRec
FROM (
SELECT uvw_EarnerInfo.feeRef, Min(uvw_EarnerInfo.feeBudRec) as AvailableTime
FROM uvw_EarnerInfo
GROUP BY
uvw_EarnerInfo.feeRef
) as x INNER JOIN uvw_EarnerInfo as a ON a.feeRef = x.feeRef AND a.feeBudRec = x.AvailableTime;
The problem is that I have no idea how to insert that subquery into the query I'm using to produce the report (as follows):
SELECT
uvw_EarnerInfo.feeRef
,uvw_EarnerInfo.PersonName
,uvw_EarnerInfo.PersonSurname
,uvw_EarnerInfo.feePin
,uvw_RB_TimeLedger.TimeDate
,uvw_RB_TimeLedger.matRef
,uvw_RB_TimeLedger.TimeTypeCode
,uvw_RB_TimeLedger.TimeCharge
,uvw_RB_TimeLedger.TimeElapsed
,uvw_WoffTimeByTime.WoffMins
,uvw_WoffTimeByTime.WoffCharge
,uvw_EarnerInfo.feeBudRec
,uvw_EarnerInfo.personOccupation
FROM
uvw_RB_TimeLedger
LEFT OUTER JOIN uvw_WoffTimeByTime
ON uvw_RB_TimeLedger.TimeId = uvw_WoffTimeByTime.TimeId
RIGHT OUTER JOIN uvw_EarnerInfo
ON uvw_EarnerInfo.feeRef = uvw_RB_TimeLedger.feeRef
WHERE
uvw_RB_TimeLedger.TimeDate >= #TimeDate
AND uvw_RB_TimeLedger.TimeDate <= #TimeDate2
If that subquery will get the correct results, can anyone please help me with inserting it into my report query. Otherwise, can anyone let me know what I will need to do to get a unique feeBudRec value for each feeRef?
Depends on the exact schema, but assuming the uvw_EarnerInfo lists the Pin, Ref, and Rec without duplicates, try adding an extra column (after personOccupation) on the end of your query such as :
feeBudRecSum = (Select SUM(FeeBudRec) From uvw_EarnerInfo x
where x.feePin = uvw_EarnerInfo.feePin
Group By x.FeePin)
Note that you would not Sum these values in your report. This column should have the total you are looking for.
The key to Report Builder is to get your query correct from the offset and let the wizard then structure your report for you. It takes all the hard work out of structuring your report manually.
I haven't used Report Builder for a while now but in the query builder of the report displaying the graphical representation of your query you should be able to drag and drop columns in and out of the query set. Dragging a column upwards and out of the box (showing your columns) would have the effect of causing your report to break on this column.
If you restructure this way you will probably have to run the report generator again to regenerate the report and restructure it.
Once you are happy with the structure you can then begin to add the summary columns.
I'm having trouble with Microsoft Access 2003, it's complaining about this statement:
select cardnr
from change
where year(date)<2009
group by cardnr
having max(time+date) = (time+date) and cardto='VIP'
What I want to do is, for every distinct cardnr in the table change, to find the row with the latest (time+date) that is before year 2009, and then just select the rows with cardto='VIP'.
This validator says it's OK, Access says it's not OK.
This is the message I get: "you tried to execute a query that does not include the specified expression 'max(time+date)=time+date and cardto='VIP' and cardnr=' as part of an aggregate function."
Could someone please explain what I'm doing wrong and the right way to do it? Thanks
Note: The field and table names are translated and do not collide with any reserved words, I have no trouble with the names.
Try to think of it like this - HAVING is applied after the aggregation is done.
Therefore it can not compare to unaggregated expressions (neither for time+date, nor for cardto).
However, to get the last (principle is the same for getting rows related to other aggregated functions as weel) time and date you can do something like:
SELECT cardnr
FROM change main
WHERE time+date IN (SELECT MAX(time+date)
FROM change sub
WHERE sub.cardnr = main.cardnr AND
year(date)<2009
AND cardto='VIP')
(assuming that date part on your time field is the same for all the records; having two fields for date/time is not in your best interest and also using reserved words for field names can backfire in certain cases)
It works because the subquery is filtered only on the records that you are interested in from the outer query.
Applying the same year(date)<200 and cardto='VIP' to the outer query can improve performance further.
