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" 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.

Best way to select distinct values based on another column?

I have a table with three columns: id (NUMBER), data_dt (DATE), and data_value (NUMBER).
There is a primary key on id and data_dt.
I want to select the record with the latest data_dt for each unique id.
What is the best way to do this?
I have three different methods, but there may be something I am missing.
First:
SELECT *
FROM
SELECT id, data_dt, data_value,
         FIRST_VALUE(data_dt)
         OVER (PARTITION BY id ORDER BY data_dt DESC) AS last_data_dt
FROM the_table
WHERE data_dt = last_data_dt;(I use ORDER BY...DESC instead of just ORDER BY so I don't need the ROWS BETWEEN clause)
Second:
SELECT t1.*
FROM the_table t1
JOIN
SELECT id, MAX(data_dt) AS last_data_dt
FROM the_table
GROUP BY id
) t2 ON (t2.id = t1.id AND t2.data_dt = t1.data_dt);Third:
SELECT t1.*
FROM the_table t1
WHERE t1.data_dt =
SELECT MAX(t2.data_dt)
FROM the_table t2
WHERE t2.id = t1.id
);-- Don

Hi,
There are more possible scenario's, for example:
select t1.*
from   the_table t1
where not exists ( select null
                   from   the_table t2
                   and    t2.data_dt > t1.data_dt
What is the best way to do this?Only you can tell:
Test all scenario's, check the execution plans, set timing on and pick the best/fastest one ;-)
If it's not clear, please post the execution plans here.

Formula to select first record on the column

Hi All
I need a formula to select a first record on the column, here is my query
SELECT DISTINCT
                      dbo.OWOR.DocNum, dbo.OWOR.ItemCode, dbo.OWOR.Status, dbo.OWOR.PlannedQty, dbo.ITM1.Price, dbo.OWOR.Warehouse,
                      dbo.OWOR.PlannedQty * dbo.ITM1.Price AS Total
FROM         dbo.OWOR INNER JOIN
                      dbo.ITM1 ON dbo.OWOR.ItemCode = dbo.ITM1.ItemCode
WHERE     (dbo.OWOR.Status = 'P') OR
                      (dbo.OWOR.Status = 'R') AND dbo.ITM1.Price
I need to select the first price on the price list for (dbo.ITM1.Price).
Regards
Bongani

Bongani,
Are you sure you don't want to link a pricelist? Because the unique key on ITM1 consists of ItemCode and PriceList and taking the first price for an item in ITM1 could result in kind of random prices for different items, depending on whice pricelist gets filled first for a certain item.

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>

       <Name>ABC</Name>
        <Role>Manager</Role>
         <Area>Bangalore</Area>
     </Details>

The output XML is:

         <table name = 'Roles'>

            </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,

Select distinct for a date column in present. service when creating prompt

hi all
I am trying to create some new prompts in my answers and I have the following problem. When I try to create a new prompt on a date column ( for example Modification Date), when I try to run this report on this prompt it is displaying the same date a lot of times ( for example 2/4/11 it is being displayed 4 times).
Is there any way i can change this, so to display distinct dates?
Thank you and best regards

Hi Deva
I am trying to use this, but in the system are being saved the date + hour.
When i try select distinct modification date from My_view, i still have the same dates because they have different hours.
When i try select disctinct to_date(modification_date)..... I am having an error in BI.
Please help me to solve this issue.

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('more than one column') from ....

Why does this sql statement not work:
select distinct(column_a, column_b, column_c), empno
from emp;
How can I 'select distinct' using more than one column.

Actually, DISTINCT applies to all columns in the result.
Distinct is not a function, you cannot do distinct(column1, column2, ...).
As a matter of fact it doesn't make sense to expect distinct applies to only one column, because you do not specify any criteria on how to select the values for the second column.
A final note: you can do distinct(column1), column2, but this will still apply to both columns!
Here're some examples that will all return both rows from the set, where set is: (1,1), (1,2):
select distinct val1, val2
from
select 1 as val1, 1 as val2 from dual
union all
select 1 as val1, 2 as val2 from dual
select distinct val1||'-'||val2
from
select 1 as val1, 1 as val2 from dual
union all
select 1 as val1, 2 as val2 from dual
select distinct(val1), val2 -- this is very misleading. distinct still applies to both columns
from
select 1 as val1, 1 as val2 from dual
union all
select 1 as val1, 2 as val2 from dual

Select Distinct (More than one column)

Hi All,
I have the following SQL statement written in MySQL that returns only one row per MODCODE with the associated DEPTCODE of AE:
SELECT DISTINCT
EL_MODULE.DEPTCODE, EL_MODULE.MODCODE, EL_MODULE.MODNAME, EL_MODULE.MODLEVEL, EL_DEPTLEVEL.DEPTLEVELHEADER
FROM EL_DEPTLEVEL, EL_MODULE
WHERE EL_MODULE.MODLEVEL = EL_DEPTLEVEL.LEVELCODE AND EL_MODULE.DEPTCODE='AE' ORDER BY EL_MODULE.MODLEVEL
However when I attempt to use this in oracle it returns three rows, could somebody point out what it is I need to change to get this working correctly in oracle.
Hope someone can help.
Jon

Duplicates? No way! This query returns unique comibination of
EL_MODULE.DEPTCODE,
EL_MODULE.MODCODE,
EL_MODULE.MODNAME,
EL_MODULE.MODLEVEL and
EL_DEPTLEVEL.DEPTLEVELHEADER

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

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.

Dynamic selection of records based on checkbox checked

Hello,
I want to select a list of records from a multirecord block by
using the checkbox checked values as the criterion and use the
records selected in the where clause for querying in another
forms. The data from the multirecord block is from a query
result and hence is dynamic.
I went about doing this:
I created a multirecord block. In the multirecord block, I
created a checkbox which was a non-database item.
In the when_button_pressed trigger I wrote the following code:
declare
     temp varchar2(1000);
     start_rec number;
     stop_rec number;
     item_id item;
     block_id block;
     item_value varchar2(1000);
     pl_id paramlist;
     item_name varchar2(10);
     patient_list varchar2(1000);
begin
go_block('patient_list');
block_id:=find_block('patient_list');
start_rec:=1;
stop_rec:=get_block_property(block_id,query_hits);
for i in start_rec..stop_rec loop
if :selection='Y' then --selection is the checkbox
     if item_value is null then
/*item_value holds the value of the data shown in the forms &
for which the checkbox is checked*/
item_value:=name_in(':patient_list.patient_id');
/*patient_id is the item name as well as field name in the
table*/
     else
item_value:=item_value||','||name_in(':patient_list.patient_id');
     end if;
end if;
end loop;
patient_list:='('||item_value||')';
pl_id:=create_parameter_list('list_of_patients');
add_parameter(pl_id,'querypatients',text_parameter,patient_list);
message(patientlist);
run_product
(forms,'patient_history',synchronous,runtime,filesystem,pl_id,nul
l);
end;
When I run this form, patient_list comes as
(111,111,111,111,111,111,111) where
111 is the value of the patient_id.
The only value that gets into the patient_list is the patient_id
for the last checkbox I have
checked in the forms and the same patient_id appears so many
times.
Can anyone tell me where I am doing the mistake? Why is the same
value appearing so many times and only the last record selected
appears in the patient_list.
Thank you for your suggestions.

Thank You.
I added go_record(start_rec) and next_record and everything
worked fine.
Here I have the working code:
declare
     temp varchar2(1000);
     start_rec number;
     stop_rec number;
     item_id item;
     block_id block;
     item_value varchar2(1000);
     pl_id paramlist;
     item_name varchar2(10);
     patient_list varchar2(1000);
begin
     go_block('patient_list');
     block_id:=find_block('patient_list');
     start_rec:=1;
     stop_rec:=get_block_property(block_id,query_hits);
go_record(start_rec);-- I added it
     for i in start_rec..stop_rec loop
     if :selection='Y' then --selection is the checkbox in
the patient_list block.
     if item_value is null then
-- item_value holds the value of the data shown in the forms and
for which the checkbox is checked
     item_value:=name_in(':patient_list.patient_id');
-- patient_id is the item name as well as field name in the table
     else
     item_value:=item_value||','||name_in
(':patient_list.patient_id');
     end if;

Selection of records based on minimum date actioned

CA Forum: Data Connectivity and SQL
Hi!
I've been building a report that displays records, grouped by the Service Department to which they have been assigned; however I need to constrain the report to only show the Service Department to which the record was first assigned. I had tried to group the report by incident reference #, and had in the details the actions taken agains the record, the date of the action, the SVD to which it was assigned, etc. In the Select Expert, I have the following:
{INC_DATA.EVENT_TYPE} = "i" and{SERV_DEPT.SERV_DEPT_SC} = "DISPATCH" and{INCIDENT.DATE_LOGGED} in DateTime (2007, 05, 01, 00, 00, 00) to DateTime (2007, 05, 30, 00, 00, 00) and{SERV_DEPT_1.SERV_DEPT_SC} in ["CUSTHOME", "CUSTWEST", "HARDWARE"]
The SERV_DEPT_1 table will displays the information about the Service Department to which the records are assigned. I need to be able to count only the minimum date of assignment. I've tried using the Minimum function, but it appears that I then can't summarize (count records) higher up in the report groups, as it gets evaluated after (?) the groups are made.
Is anyone able to offer suggestions as to how I might go about this? I have tried to somehow flag records in the details which meet the criteria, but haven't been able to come up with anything yet.
Thanks!

I'm not quite sure how/where you tried to use the Minimum function - sounds like you used it in the record selection formula? Anyway, if you want the report to have only the earliest record per service department group then you can use the group selection expert, e.g.{incident.date_logged} = minimum({incident.date_logged}, {serv_dept_1.serv_dept_sc})If you want to display the earliest record but still have the other records there for processing then sort on {incident.date_logged} ascending, suppress the details, and print in the {serv_dept_1.serv_dept_sc} group header. i.e the record you're "looking" at in the group header is the first one for the group.The difference between the two is that the former will only have one record per service department group (assuming the date_logged is unique per incident per department) while the latter will have all records but only display one. This makes a difference when using the built-in summary functions.
