Hi Expart ,
I have table fields like function ,tcode,objects,fields,from ,to ,user like that in which except user all r primary key fields but i want Number of unique Function-Tcode-Object combinations when select the data.
i am doing like that
SELECT COUNT( distinct FUNCTIONID TCODE OBJECT)
FROM /PSYNG/FUNCTTRAN
INTO L_FUN_TCD_OB
WHERE VRSIO = P_VRSIN.
but it will give an error
plz help me to get no of this combination of records .
Thanks in advance .
Tsen

hi
u can write code like this
SELECT distinct FUNCTIONID TCODE OBJECT
FROM /PSYNG/FUNCTTRAN
INTO table it_L_FUN_TCD_OB
WHERE VRSIO = P_VRSIN.
data: var type sy-tabix.
describe table it_L_FUN_TCD_OB lines var.

now i want to select one record for each cnt_id without using any distinct function .. how can i do that?

you can use the below query
select * from t where rowid in (select max(rowid)
from t group by cnt_id)You're query is not the equivalent of DISTINCT.

"Select Distinct Records" Option Not Available

Hello Experts.
I am working on a new report in CR XI, and noticed that I had many duplicate records. I went to the File; Report Options; and expected to click on "Select Distinct Records", but that choice was grayed-out. What would have caused me to lose this option, and how do I fix it?
Thanks in advance for your help.

Not sure if this covers it or not, but....
The Select Distinct Records command is only available for ODBC, OLE DB, and SQL native drivers; it is not available for Stored Procedures. Note also that your server may automatically sort returned values if no sort is specified in Crystal Reports.

Select distinct records in query

If I want to read a table in an infoset, how can I just select distinct entries from the table?
Is it done at the infoset level or the query level?

I've actually created the infoset for table VBFA and created a query.
But I can't limit the output such that for each DO, show only distinct subsequent Invoice.
eg. DO 123 has 3 items, and this DO 123 has only 1 Invoice 456, then in the output, there will be
DO    |     Invoice
123   |     456
123   |     456
123   |     456
It's repeated 3 times because there are 3 items in VBFA for this DO. How can I create the infoset/query so that the output will be 1 entry only, ie
DO    |     Invoice
123   |     456
Thanks

Select distinct record based on column

Hello All,
I have a table that has more than one row as Detail for a single invoice number(screenshot below). When I create report based on this table, I get multiple rows for single invoice. I mean Invoice 000027 shows up with 5 different rows on the SSRS report.
Is there a way I could display a single row for a single invoice? Any thoughts on this will be greatly appreciated. Thanks.

Thank you all for your suggestions. The issue is how can I get single distinct columns after joining 2 tables (InvoiceHeader & InvoiceDetail). I am using following query in my dataset.
SELECT DISTINCT I.recid, I.InvNumber, D.Detail, I.CompanyName, I.Addr1, I.SalesRep, I.JobNumber, I.Status, I.InvDate, I.TotalInvAmount
FROM InvoiceHeader AS I INNER JOIN
InvoiceDetails AS D ON I.InvNumber = D.InvoiceNumber
WHERE (I.InvNumber = @InvoiceNumber) AND (I.InvDate >= @StartDate) AND (I.InvDate <= @EndDate) AND (I.CompanyName IN (@Customer)) AND (I.Status IN (@Status)) OR
(I.InvDate >= @StartDate) AND (I.InvDate <= @EndDate) AND (I.CompanyName IN (@Customer)) AND (I.Status IN (@Status)) AND (I.JobNumber = @JobNo) OR
(I.InvNumber = @InvoiceNumber) AND (I.InvDate >= @StartDate) AND (I.InvDate <= @EndDate) AND (I.CompanyName IN (@Customer)) AND (I.Status IN (@Status))
AND (@JobNo = '') OR
(I.InvDate >= @StartDate) AND (I.InvDate <= @EndDate) AND (I.CompanyName IN (@Customer)) AND (I.Status IN (@Status)) AND (I.JobNumber = @JobNo) AND
(@JobNo = '') OR
(I.InvDate >= @StartDate) AND (I.InvDate <= @EndDate) AND (I.CompanyName IN (@Customer)) AND (I.Status IN (@Status)) AND (@JobNo = '') AND
(@InvoiceNumber = '')
ORDER BY I.InvNumber DESC
Thanks again.

Help! Howto use the join function in a query with select distinct ?

Hi!
I have 2 tables. I want to select only 1 painting of each artists.
select distinct idartist

Getting a single random image for each probably requires a combination of sql and cf. It would take someone smarter than me to do it with sql alone. I would probably try something like this:
1. Run a database query that gets all the images from all the artists.
2. Run a Q of Q that gets a distinct list of artist ids.
3. Loop through that list and run a Q of Q to get all the images for that artist.
4. Still in that loop, use randrange (1 to the recordcount) to select a random record from your Q of Q

Hi,
Do a self-join, to combine the two rows for each value of id1 onto one output row.
Make it an outer join, in case there is only one row with a vlaue for id1.
SELECT l.id1
,     l.name1
,     NVL ( r.name11
         , l.name11
         )          AS name11
FROM              table1     l
LEFT OUTER JOIN     table1     r ON l.id1     = r.id1
                          AND l.name1     < r.name1
;Edited by: Frank Kulash on Jul 25, 2011 12:57 PM
Sorry, I mis-read the problem.
Lee's solution, above, assumes that name1 is unique, as it is in your sample data.
What output would you want if that's not the case?
If name1 is not unique, but the combination of (id1, name1) is unique, then you can modify Lee's solution like this:
SELECT *
FROM    table1
WHERE   (id1, name1) IN (
                    SELECT    id1
                    ,       MAX (name1)
                           FROM          table1
                    GROUP BY id1
;Or, if you can't make any assumptions about uniqueness, you might need something like this:
WITH     got_r_num     AS
     SELECT id1, name1, name11
     ,     ROW_NUMBER () OVER ( PARTITION BY id1
                               ORDER BY         name1     DESC
                         ,                name11     DESC
                       )      AS r_num
     FROM     table1
SELECT id1, name1, name11
FROM     got_r_num
WHERE     r_num     = 1
;

Serious performance problem - SELECT DISTINCT x.JDOCLASSX FROM x

I am noticing a huge performance problem when trying to access a member that
is lazily loaded:
MonitorStatus previousStatus = m.getStatus();
This causes the following query to be executed:
SELECT DISTINCT MONITORSTATUSX.JDOCLASSX FROM MONITORSTATUSX
This table has 3 million records and this SQL statement takes 3 minutes to
execute! Even worse, my app heavily uses threads, so this statement is
executed in each of the 32 threads. As a result the application stops.
Is there any way that I can optimize this? And more importantly, can Kodo
handle a multithreaded app like this with a huge database? I've been having
a lot of performance problems since I've started doing stress & load
testing, and I'm thinking Kodo isn't ready for this type of application.
Thanks,
Michael

You can prevent this from happening by explicitly enumerating the valid
persistent types in a property. See
http://docs.solarmetric.com/manual.html#com.solarmetric.kodo.PersistentTypes
for details.
>
Inconveniently, this nugget of performance info is not listed in the
optimization guide. I'll add in an entry for it.This setting did in fact prevent the query from running which fixed the
problem. It definitely belongs in the optimization guide.
And more importantly, can Kodo
handle a multithreaded app like this with a huge database? I've beenhaving
a lot of performance problems since I've started doing stress & load
testing, and I'm thinking Kodo isn't ready for this type of application.I'd like to find out more information about details about your issues. We
do a decent amount of stress / load testing internally, but there are
always use cases that we don't test. Please send me an email (I'm assuming
that [email protected] is not really your address) and let's
figure out some way to do an analysis of what you're seeing.This email is just for posting to usenet, to avoid spam. I'm now running my
app through stress/load testing so I hope to discover any remaining issues
before going into production. As of this morning the system seems to be
performing quite well. Now the biggest performance problem for me is the
lack of what I think is called "outer join". I know you'll have this in 3.0
but I'm suprised you don't have this already because not having it really
affects performance. I already had to code one query by hand with JDBC due
to this. It was taking 15+ minutes with Kodo and with my JDBC version it
only takes a few seconds. There are lots of anti-JDO people and performance
issues like this really give them ammunition. Overall I just have the
impression that Kodo hasn't been used on many really large scale projects
with databases that have millions of records.
Thanks for configuration fix,
Michael

Select from table of records

Hi,
Inside of a stored procedure I created:
- a record type:TYPE gr_rec IS RECORD (contact_id number)
- a table of records: TYPE gr_tb IS table of gr_rec INDEX BY BINARY_INTEGER
and then I populated the table in a loop: tb(i).contact_id := a.contact_id.
My question is:
Is it posible to perform a select statement on the table of records to get only distinct records?
If not, how can I filter these records, as I use the procedure as a block data source in a form and I need only distinct records.
Note: I can not obtain select rows from the query that populates the table.
Thank you, Monica

Select distinct from an infoset query

Hello
I need to select distinct / delete duplicate from an infoset query created thru SQ02.
Please let me to know how this can be done?
Many thanks in advance!
regards
Sanjyot

Hi,
You can verywell use infoset query if you are doing following things
Join using Keyfields to retreive data from tables
If not using keyfields create index for those table fields in those fields which will improve in accessing database
Try to use minimum of tables of small size dont try to join big tables like GLPCA and all.
Try to load small set of data like a period or month. Dont try for a year or so.
if your performance is good for aperiod you can go for a year.
If you are good in function module you can try function module in which you will have the option of specifying no of records to be selected usign package size.
Hope this helps for you.
Thanks,
Arun

SELECT DISTINCT does not work. Why?

Dear All,
I wrote the Query below in SAP B1 8.8 and it works fine.
But, for some strange reason, certain records are duplicated.
Could anybody explain why?
I tried to eliminate the duplicates by changing the 1st line of the Query from SELECT to SELECT DISTINCT
Error Message:
The ntext data type cannot be selected as DISTINCT because it is not comparable.
Could you help amend the Query?

Dear István Korös,
Thanks a lot for your answer.

However, I have never met the problem of duplicate records before

If you could explain to me why such duplicates arose, it would be very
satisfying.

Select Distinct Fields from non related table

Hi Experts,
I have to fetch Distinct Fields from table zdcxy along with the fields from the table zvend but there is no primary key forigen key relationship also if I wanted use join condition. I need to move fields from both the table into output file and 1 part I implemented but I am unable to do second part plz any body can help me its argent. below I pasted part of code along with two requirements.
1.Select all data (Location - LIFNR, Descr u2013 ZPLTNAMEC, CJI_CUSTOMER u2013 CJI customer flag) from ZVEND table.
2.Select all distinct DCs and BUs from zdcxy table.
SELECT * FROM ZVENDPLT INTO CORRESPONDING FIELDS OF TABLE IT_VENDPLT.
*select distinct zdc from zdcxy into corresponding fields of table it_map.
*select distinct zbu from zdcxy into corresponding fields of table it_map.
IF SY-SUBRC = 0.
    LOOP AT IT_VEND.
      MOVE : IT_VENDPLT-LIFNR              TO IT_TAB-FIELD1,

SELECT DISTINCT does not work - Another Problem!

Dear All
Previous Post
I just posted a thread, which has been answered by an expert. It's here:
SELECT DISTINCT does not work. Why?
My original problem was that the Query returned duplicate records, and SELECT DISTINCT did not work.
The solution was to change this select:
T0.[U_SupInv]      AS 'Link'
... to this:
CAST(T0.[U_SupInv] as nvarchar(100))      AS 'Link'
The amended Query worked.
New Problem
I just discovered that resolving the problem created a new one.
The field U_SupInv (Link) is in fact a UDF.
I created it so that all Suppliers' Invoices could be Scanned to pdf files, and these pdf could be linked
to the respective AP Invoice.
Originally, when I clicked 'Link' in my Query results, the pdf scan pops up.
When the Query is amended by adding CAST, the link becomes dead.
Help
Could anyone tell me how I can make SELECT DISTINCT work, as well keeping the LINKS live?
The main purpose of my Query is to help users view the pdf scans by clicking on the links.
Thanks

Dear István Korös,
Thanks a lot for your answer.
I will test your suggestion tomorrow, as it's night and I am returning home now.
However, I do not think it will suit my requirements for the foll reasons:
- I worked hard to get rid of the need to enter anything in the @Scan2 field.
- This UDF was created solely as a text of instruction for my staff.
   Unfortunately I had to fill in something to make the Query work.
- The problem is that if the user forgets to click the drop-down arrow and leaves @Scan2
   blank, the query does not work.
- With the help of another expert, I succeeded in ignoring @Scan2 altogether.
- I posted only a simplified version of my Query on the forum, without the codes relating to eliminating the
need to enter something in @Scan2, so you may not be aware of my requirement.
- I hope you understand my reluctance. But I will try your suggestion nevertheless.
My Suggestion
I think using PCH1.VISORDER may be the solution.
If we select only those rows where visorder = 0, then
   - there will be no duplication
   - I need not use SELECT DISTINCT
   - All my LINKS to pdf files will be live because I need not use CAST
   - I may retain that part of my Query which permits ignoring @Scan2 altogether.
- A Dream!-
The problem is that I don't know how and where to place that VISORDER.
If you think I may be right, could you help me along that line?

Count distinct combinations

I have a table which has 3 columns a, b, c
there could be duplicates in a/b/c.
I want to count the total number of distinct combinations of a, b, c using a select query (i.e. the result of the select query should be the count). How do I do this?

Look, Elic, for all practical purposes count(*) is equivalent to sum(1). Therefore:
1. Argument to the count doesn't make any sense
2. count aggregate function is redundant
Browse any mathematical book. Do you see any count symbols in it? Nope. Only sigmas (summation) and occasional pi's (multiplication). OK, even more infrequently lattice joins (maximum) and meets (minimum).

Select one among multiple record

Dear all,
how can i create a select statement which returns only one record if there are the same values in tkn and numero column?
Table ROSE
TKN NUMERO
75684523 4523
75684523 4523
75684523 4523
Thank you,

You can just use DISTINCT keyword if you have just two columns in your table
with t as
    select 75684523 tkn, 4523 numero from dual union all
select 75684523, 4523 from dual union all
select 75684523, 4523 from dual union all
select 99984523, 3333 from dual union all
select 99984523, 3333 from dual
select distinct tkn,numero from t;
TKN                    NUMERO
99984523               3333
75684523               4523       Or if you have more number of columns in the table but still you want to get only one row then you can use either of the above mentioned methods by gurus.
with t as
    select 75684523 tkn, 4523 numero, 12 eid from dual union all
select 75684523, 4523, 12 from dual union all
select 75684523, 4523, 13 from dual union all
select 99984523, 3333, 14 from dual union all
select 99984523, 3333, 15 from dual
select l.tkn, l.numero, eid
from
       select t.tkn, t.numero,eid, row_number() over (partition by t.tkn, t.numero order by 1) rn
       from t
     ) l
where rn = 1
