My issue is when executing a stored procedure in a DataSet (exec pStoredProcedure) and SSRS populates different Fields for me to use. I wish to make an additional query to one of these fields.
DataSet 1 is:
exec pInfos #SessionGUID=#SessionGUID
Dataset 2 is simply:
select * from myTable where infoHeader is #HeaderInfo
In this query, #HeaderInfo is my dataField from the first DataSet that is returned. Note that the tablix is expanding for the number of #HeaderInfo there happens to be.
What's a simple way to put this field in as the parameter and put the result onto a tablix? (note the tablix data source is dataset1).
Special thanks to TMNT2014 for his comment!
I found two answers to my own question:
The first is to use Lookup, in which I did
select * from myTable
I then did a Lookup as:
=Lookup(Field!Headerinfo, Field!infoHeader, Field!ResultValue, "myTable")
And the value is as I needed it. I also found that by navigating to parameters and adding your own, you can specify the default Values of that parameter (in parameter settings) and then select the Dataset -> Value Field. Although I didn't test this one, I thought I'd include it.
I found this hard to follow, plus I needed to run my lookup in the group of my first dataset which required more than one lookup field.
First I wasted a ton of time with parameters. Nothing worked. Finally, I just added the fields I needed as the lookupset parms to my dataset query;
DataSet1 query:
Select a.c1, a.c2, a.c3, rtrim(ltrim(a.4))+'-'+convert(varchar(12), a.5, 101) as LookupKey from myTable a
Next I added the same key to my second dataset.
DataSet2 query:
Select b.c1, rtrim(ltrim(b.2))+'-'+convert(varchar(12), b3, 101) as LookupKey from myTable b
Now my two datasets have equivalent lookup keys based on multiple fields. Maybe there is an easier way with Lookup and LookupSet, but I didn't see it offhand.
In the Group footer of DataSet 1 I created an expression in the Tablix
=Join(LookupSet(fields!LookupKey.Value, Fields!LookupKey.Value, Fields!Comments.Value, "Comments"), vbcrlf)
And giving the following results:

I have this code in SAS, I'm trying to write SQL equivalent. I have no experience in SAS.
data Fulls Fulls_Dupes;
set Fulls;
by name, coeff, week;
if rid = 0 and ^last.week then output Fulls_Dupes;
else output Fulls;
run;
I tried the following, but didn't produce the same output:
Select * from Fulls where rid = 0 groupby name,coeff,week
is my sql query correct ?
SQL does not have a concept of observation order. So there is no direct equivalent of the LAST. concept. If you have some variable that is monotonically increasing within the groups defined by distinct values of name, coeff, and week then you could select the observation that has the maximum value of that variable to find the observation that is the LAST.
So for example if you also had a variable named DAY that uniquely identified and ordered the observations in the same way as they exist in the FULLES dataset now then you could use the test DAY=MAX(DAY) to find the last observation. In PROC SQL you can use that test directly because SAS will automatically remerge the aggregate value back onto all of the detailed observations. In other SQL implementations you might need to add an extra query to get the max.
create table new_FULLES as
select * from FULLES
group by name, coeff, week
having day=max(day) or rid ne 0
;
SQL also does not have any concept of writing two datasets at once. But for this example since the two generated datasets are distinct and include all of the original observations you could generate the second from the first using EXCEPT.
So if you could build the new FULLS you could get FULLS_DUPES from the new FULLS and the old FULLS.
create table FULLS_DUPES as
select * from FULLES
except
select * from new_FULLES
;
I'm trying to query my database to pull only duplicate/old data to write to a scratch section in excel (Using a macro passing SQL to the DB).
For now, I'm currently testing in Access alone to only filter out the old data.
First, I'm trying to filter my database by a specifed WorkOrder, RunNumber, and Row.
The code below only filters by Work Order, RunNumber, and Row. ...but SQL doesn't like when I tack on a 2nd AND statement; so this currently isn't working.
SELECT *
FROM DataPoints
WHERE (((DataPoints.[WorkOrder])=[WO2]) AND ((DataPoints.[RunNumber])=6) AND ((DataPoints.[Row]=1)
Once I figure that portion out....
Then if there is only 1 entry with specified WorkOrder, RunNumber, and Row, then I want filter it out. (its not needed in the scratch section, because its data is already written to the main section of my report)
If there are 2 or more entries with said criteria(WO, RN, and Row), then I want to filter out the newest entry based on RunDate and RunTime, and only keep all older entries.
For instance, in the clip below. The only item remaining in my filtered query will be the top entry with the timestamp 11:47:00AM.
.
Are there any recommended commands to complete this problem? Any ideas are helpful. Thank you.
I would suggest something along the lines of the following:
select t.*
from datapoints t
where
t.workorder = [WO2] and
t.runnumber = 6 and
t.row = 1 and
exists
(
select 1
from datapoints u
where
u.workorder = t.workorder and
u.runnumber = t.runnumber and
u.row = t.row and
(u.rundate > t.rundate or (u.rundate = t.rundate and u.runtime > t.runtime))
)
Here, if the correlated subquery within the where clause finds a record with the same workorder, runnumber and row, but with either a later rundate or the same rundate and a later runtime, then the record is returned by the main query.
You need two more )'s at the end of your code snippet. Or you can delete the parentheses completely in this example, MS Access will ad them back in as it deems necessary.
M.S. Access SQL can be tricky as it is not standards compliant and either doesn't allow for super complex queries, or it needs an ugly work around, like having a parentheses nesting nightmare when trying to join more than two tables.
For these reasons, I suggest using multiple Access queries to produce your results.
I have a list of 2500 obj numbers stored in Excel for which I need to run the below SQL:
SELECT
a.objno,
a.table_comment,
b.queue_comment
FROM
aq$_queue_tables a
JOIN
AQ$_QUEUES b ON a.objno = b.table_objno
WHERE
a.objno = 19551;
Is there any way I can write a loop on above SQL with objno feeding from a list or from a different table? I also want to store/produce all the results from each loop run as a single output.
I considered the option to upload the numbers into a new table and add a where condition:
a.objno=(SELECT newtab.objectno FROM newtab);
However, the logic I'll be writing in the query would exclude certain objectno results. Let's say that the associated objectno has certain queue_comment as of certain date associated with that objectno. I do not want to pull that record. This condition would match with some objectno and wouldn't match with others. Having that condition and running the query against all the objectno is returning 0 results. I couldn't share the original logic as it would reveal certain business rules and it'll be a violation of some policy.
So, I need to run the query on each objectno separately and combine the results.
I'm totally new to SQL and got this task assigned. I'm aware of the regular loop, for in SQL, but I don't think I can apply them in this situation.
Any guidance or reference links to helpful topics is much appreciated as well.
Thanks in advance for the help.
One option is to upload the object numbers from Excel sheet to a table in the database and run the query as following. Assuming newtab is the table where the objectno are uploaded.
SELECT
a.objno,
a.table_comment,
b.queue_comment
FROM
aq$_queue_tables a JOIN AQ$_QUEUES b on a.objno = b.table_objno
WHERE
a.objno IN (SELECT newtab.objectno FROM newtab);
I have used a subquery here, join to the aq$ can work as well.
Reading the comments and all I think you need to enhance your Excel with 2 additional columns and load to a new table.
IN can be used in the following way too:
SELECT
a.objno,
a.table_comment,
b.queue_comment
FROM
aq$_queue_tables a
JOIN
AQ$_QUEUES b ON a.objno = b.table_objno
WHERE
(a.objno,a.table_comment,b.queue_comment) IN (19551,'something','something');
so with the new table will be:
WHERE
(a.objno,a.table_comment,b.queue_comment) IN
(select n.objno, n.table_comment, n.queue_comment from new_table n)
I have a matrix in ssrs2008 like below:
GroupName Zone CompletedVolume
Cancer 1 7
Tunnel 1 10
Surgery 1 64
ComplatedVolume value is coming by a specific expression <<expr>>, which is equal to: [Max(CVolume)]
This matrix is filled by a stored procedure that I am not supposed to change if possible. What I need to do is that not to show the data whose CompletedVolume is <= 50. I tried to go to tablix properties and add a filter like [Max(Q9Volume)] >= 50, but when I try to run the report it says that aggregate functions cannot be used in dataset filters or data region filters. How can I fix this as easy as possible?
Note that adding a where clause in sql query would not solve this issue since there are many other tables use the same SP and they need the data where CompletedVolume <= 50. Any help would be appreciated.
EDIT: I am trying to have the max(Q9Volume) value on SP, but something happening I have never seen before. The query is like:
Select r.* from (select * from results1 union select * from results2) r
left outer join procedures p on r.pid = p.id
The interesting this is there are some columns I see that does not included by neither results1/results2 nor procedures tables when I run the query. For example, there is no column like Q9Volume in the tables (result1, result2 and procedures), however when I run the query I see the columns on the output! How is that possible?
You can set the Row hidden property to True when [Max(CVolume)] is less or equal than 50.
Select the row and go to Row Visibility
Select Show or Hide based on an expression option and use this expression:
=IIF(
Max(Fields!Q9Volume.Value)<=50,
True,False
)
It will show something like this:
Note maximum value for Cancer and Tunnel are 7 and 10 respectively, so
they will be hidden if you apply the above expression.
Let me know if this helps.
Any idea how to summarize data in a Pentaho transformation and then insert the summary row directly under the group being summarized.
I can use a Group By step and get a summarised result stream having one row per key field, but what I want is each sorted group written to the output and the summary row inserted underneath, thus preserving the input.
In the Group By, you can do 'Include all Rows', but this just appends the summary fields to the end of each existing row. It does not create new summary rows.
Thanks in advance
To get the summary rows to appear under the group by blocks you have to use some tricks, such as introducing a numeric "order" field, setting the value of the original data to 1 and the sub totals rows to 2.
Also in the group-by/ sub-totals stream, I am generating a sum field, say "subtotal". You have to make sure to also include this as a blank in your regular stream or else the metadata will be divergent and the final merge will not work.
Here is the best explanation I have found for this pattern:
https://www.packtpub.com/books/content/pentaho-data-integration-4-working-complex-data-flows
You will need to copy the rows too a different stream, and then merge or join them again, to make it a separate row.
