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 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.

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 in Mapping with no Key field (all fields can vary)

Hi Experts,
Let me take an example (not the actual requirement but same scenario) to explain the problem where I need your help to get best possible way to resolve. This has to be achieved in mapping, don't have other options as its part of complex end 2 end scenario.
I have following input XML:
<Employee>
   <Details>
      <Id>123</Id>
      <Name>ABC</Name>
     <Role>Manager</Role>
      <Area>Bangalore</Area>
    </Details>
    <Details>
       <Id>123</Id>
       <Name>ABC</Name>
        <Role>Manager</Role>
         <Area>Pune</Area>
     </Details>
      <Details>
       <Id>123</Id>
       <Name>ABC</Name>
        <Role>Advisor</Role>
         <Area>Bangalore</Area>
     </Details>
      <Details>
       <Id>123</Id>
       <Name>ABC</Name>
        <Role>Manager</Role>
         <Area>Bangalore</Area>
       <Details>
       <Id>143</Id>
       <Name>ABC</Name>
        <Role>Manager</Role>
         <Area>Bangalore</Area>
     </Details>
</Employee>
The output XML is:
<Employee>
   <MainRec>
       <Id>123</Id>
        <Name>ABC</Name>
         <table name = 'Roles'>

                      <Id>123</Id>
                       <Role>Manager</Role>
                        <Area>Bangalore</Area>
                  </record>
                  <record>

            </table>
        </MainRec>
</Employee>
As you can see from the example above, here I want to populate only distinct records under table, but there is no key fiield to ditunguish. Any of the 3 fields (Id, Role,Area) can vary and between 2 records if all of these fields are same then its duplicate else select it. So in above XML just discard the 4th record from the source XML and populate all others. Each record has to be checked against all other records all 3 values (ID, Role, Area). Only when none of the records have exactly the same values, populate it.
Also records with different ID come under different table node. Hope my requirement is clear, if not please let me know, i will try to explain better.
I thought of creating a UDF to achieve this but not able to decide how to match it to the output message here.
Best Regards,
Pratik

Hi,
For the main record, I think you only need to check for each unique ID, e.g
Id --> removeContext --> sort:ascending --> splitByValue:valueChanged --> collapseContext --> MainRec
For the record, however, you need to create a UDF that will filter out the duplicate values. For this, the UDF sample mentioned here contained multipleResult lists
Id --> removeContext --> concat: : --> concat: : --> UDF --> splitByValue:ValueChanged --> record
role --> removeContext --> /          /                \ --> Id
area --> removContext -------------> /                  \ --> role
                                                         \ --> area
Context type UDF
Arguments: input
Result: IdResult
Result: roleResult
Result: areaResult
Vector temp = new Vector();
for(int a=0;a<input.length;a++){
   if(!temp.contains(input[a])
         temp.add(input[a]);
for(int a=0;a<temp.size();a++){
   String tmp = (String) temp.get(a);
   /*split according to field */
   IdResult.addValue(tmp.substring(0,tmp.indexOf(":")));
   roleResult.addValue(tmp.substring(tmp.indexOf(":")+1,tmp.lastIndexOf(":")));
   areaResult.addValue(tmp.substring(tmp.lastIndexOf(":")+1,tmp.length()));
note: Id and record will both be using the IdResult list.
Hope this helps,
Mark

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.

Select Distinct records

Hi..
I'm getting error when trying to fill the combo using select with distinct command....i have duplicate records but recordset is not working with distinct command....
Thanks..

Hi Pari,
you can solve this using GROUP By
Select U_ELCategoryCode,U_ELCategoryName from [@ENTITLEMENTCATEGORY]
group by U_ELCategoryCode,U_ELCategoryName
that will remove records where U_ELCategoryCode and U_ELCategoryName are the same.

Distinct Records Selection in Crystal 11

Need to select Distinct Records only, but the drop down under 'Database' shows the 'Select Distinct Records' option grayed out. Why does Crystal do that, and how may I eliminate duplicate records? Thanks!

Hi Brian,
This issue normally comes when there are multiple datasources being used. For example if you are using two databases, like Oracle and MS Access to fetch data, the "Select Dictinct Records" will be greyed out.
In this case, you might want to write a query in the Add Command option which select distinct records.
If you are using only one database, then check if you are able to select "Select Dinstinct Records" in the Database menu.
Please let us know if this helps.
Regards,
Abhishek.

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
from tbl_artworks
where blah blah blah
order by rand()
how does the "join" function work for add: name, lastname, title, image and much more... i try... but i fail...
tbl_artists
idartist
name
lastname
1
Paul
Gaugain
2
Vincent
Van Gogh

Pablo

tbl_artworks
idartwork
idartist
title

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

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

Toplink issues select distinct type query before fetch

When we have type classifiers identified by value, Toplink issues a 'SELECT DISTINCT TYPE' on the parent object and then queries the child records for that type, is there way to avoid the select distinct
type query from Toplink in queries, this is slowing down the query performance. thanks

bind => [249994, IdcFXSLegDealC, IdcFXSLegDealC, IdcCrncC, IdcLglEntC]
Not sure why we need to query for type on t2 and t3 after we have made a join by id (t2.id = t1.ccy1Id,t3.id = t1.cptyAId), this is really breaking our performance, we do not want to add an index on
the type column
can someone please respond!?

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

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
;

Need of SQL query in selecting distinct values from two tables

hi,
I need a query for selecting distinct values from two tables with one condition.
for eg:
there are two tables a & b.
in table a there are values like age,sex,name,empno and in table b valuses are such as age,salary,DOJ,empno.
here what i need is with the help of empno as unique field,i need to select distinct values from two tables (ie) except age.
can anybody please help me.
Thanks in advance,
Ratheesh

Not sure what you mean either, but perhaps this will start a dialog:
SELECT DISTINCT a.empno,
                a.name,
                a.sex,
                b.salary,
                b.doj
FROM    a,
        b
WHERE   a.empno = b.empno;Greg

Issue with "Select Distinct" query in Oracle 10g against Oracle 9i

Hi,
I would appreciate if some one help me here because it is really urgent.
We are upgrading our database from 9i to 10g.
There are the "Select distinct" queries in the code which populated the grid on the applications screens. We found a difference in 9i and 10g the way the result is populated for these queries. If "Select Distinct" query wihtout a order by clause is executed in 9i then the result is automatically sorted. But Oracle 10g does not do this.
We can change the queries adding order by clause but we are almost at the end of the testing and want to know if there is any way that we can do this from database settings. Would there be any impact of these settings change on overall operation of Oracle 10g?
I would appreciate if some one can help me here.
Thanks,
Dinesh

then the result is automatically sorted.No. Oracle may have done a sort operation to perform the distinct, but it still did not guarantee the order of your results.
In 10g and in 9i, if you want your results in a certain order you must use order by.
