14 rows selected.
at row no 4 and 5 for client_id = '121874001'
It has repeating END_DT = '15-DEC-03'
I want to have only one record for client_id = '121874001' where BEGIN_DT IS MINIMUM begin_Dt value (i.e. begin_Dt = '14-MAY-97' and END_DT = '15-DEC-03')
so I can have 2 rows instead of 3 rows for client_id = '121874001'
This is part of my table records my table contains multiple clients.
can some one help me writing SQL ?
Thanks in advance
Jay

To display non-repeating information while showing the minimun begin_dt, you need to apply the aggregate funtion MIN to the begin_dt column and the GROUP BY clause to the rest of the columns, as follows:
SELECT client_id, MIN(begin_dt) BEGIN_DT, end_dt, r, res_type_desc
FROM your_source_table
GROUP BY client_id, end_dt, r, res_type_desc;
(use your real column names; your pasted result set seems to append some column names)
Good luck,

Repeat Column Value derived from formulae

I need to repeat a value derived for a particular column &row combination to all rows in the table. however when I put the 'case' function it does not repeat the values as I expect. The value is only shown in the 1at row
The formulae used is as follows
CASE WHEN D_MILLS.MILL_NO =1 THEN (F_MILL_PRODUCTION.FN_YTD_CPO_PRODUCED/F_MILL_PRODUCTION.FN_YTD_CROP_PROCESSED ) ELSE (FILTER(F_MILL_PRODUCTION.FN_YTD_CPO_PRODUCED/F_MILL_PRODUCTION.FN_YTD_CROP_PROCESSED USING (D_MILLS.MILL_NO = 1.00)) ) END
Note : Mill No is the Dimension Field that I user for the report. and I require the value of derived for mill No =1 to be repeated to all other mills (Mill No =2,3 etc)
Edited by: Shaz01 on Aug 7, 2010 1:45 AM

Hi,
Use the formula like this,
Max(CASE WHEN D_MILLS.MILL_NO =1 THEN (F_MILL_PRODUCTION.FN_YTD_CPO_PRODUCED/F_MILL_PRODUCTION.FN_YTD_CROP_PROCESSED ) ELSE (FILTER(F_MILL_PRODUCTION.FN_YTD_CPO_PRODUCED/F_MILL_PRODUCTION.FN_YTD_CROP_PROCESSED USING (D_MILLS.MILL_NO = 1.00)) ) END)
Also for all the values you need to show the value of Mill no 1, so no need for case statement.
MAX(FILTER(F_MILL_PRODUCTION.FN_YTD_CPO_PRODUCED/F_MILL_PRODUCTION.FN_YTD_CROP_PROCESSED USING (D_MILLS.MILL_NO = 1.00)))

How to not repeat the column values if repeated on next line and so on..?

Hi all,
The XmlP template that is designed gives me the output as follows :
COL1 COL2 COL3 COL4 COL5 COL6 COL7
abc 1 1000.00 10.00 95.00 695.00 cad
abc 2 1000.00 100.00 95.00 695.00 cad
abc 3 1000.00 100.00 95.00 695.00 cad
But my requirement is as follows :
COL1 COL2 COL3 COL4 COL5 COL6 COL7
abc 1 1000.00 10.00 95.00 795.00 cad
- 2 - 100.00 - - -
- 3 - 100.00 - - -
Note : "-" indicates blank column values (gaps are being filled)
How do I not repeat the column values if repeated?
Please let me know if you have answer for it?
Thanks in Advance
Munna

Iam trying to design the xml publisher template using xmlp template builder.
My requirement is :
For a receipt number, I have receipt amount, applied amount, unapplied amount and on account amount. And for each receipt, there can be multiple applied amount ( as the receipt can be applied multiple times), but the unapplied amount, on account amount and receipt amount is single.
By using the logic as said above from http://blogs.oracle.com/xmlpublisher/2007/04/13
Iam getting the output something like this:
Receipt Number| Receipt Amount | App Amount |UnappAmount|OnaccountAmount|
111-b|249.28|249.28|0.00|0.00|
1110|1,000.00|10.00|95.00|795.00|
1110| -|10.00|-|-|
1112|1500.00|1,271.02|-|-|
1112|-|228.98|-|-|
My requirement is to go get something like this:
Receipt Number| Receipt Amount | App Amount |UnappAmount|OnaccountAmount|
111-b|249.28|249.28|0.00|0.00|
1110|1,000.00|10.00|95.00|795.00|
1110| -|10.00|-|-|
1112|1500.00|1,271.02|0.00|0.00| ---> here lies the difference
1112|-|228.98|-|-|
How do i check the duplicate of the column values only for a receipt number??
Because as for receipt no. 111-b the unapplied amount and on account amount is 0.00, the the unapplied amount and on account amount for receipt number 1112 is getting hided( because its a duplicate) . In reality, it should be 0.00 and any other line for that receipt number (1112) should be hided. except for the applied amount.
Note We can see that last 2 columns in the last record( for receipt number 1112) is getting hided that is as expected but for 4th record the unapplied amount and on account amount should be 0.00 respecively.
'-' indicates hided value
Please help.
Thanks in Advance

How to repeat rows based on column value

Hi all,
I have a query that gives me a result with a column value for example 4.
I now want to repeat this row 4 times with a new column that calculated from 1 - 4.
Or when column value is 3 I want to repeat row 3 times with new column name 1-3
Can anyone help me with this please? :)

Hi Yvanlathem,
To achieve your requirement, you can reference the recursive approach as below.
DECLARE @T TABLE(Col1 CHAR(1),Col2 INT)
INSERT INTO @T VALUES('A',1),('B',2),('C',3)
;WITH Cte([Char],[Repeat]) AS
SELECT Col1,Col2 FROM @T
UNION ALL
SELECT [Char],[Repeat]-1 FROM Cte
WHERE [Repeat]>1
SELECT * FROM Cte ORDER BY [Char],[Repeat]
OPTION(MAXRECURSION 0)
/* Output
Char Repeat
A 1
B 1
B 2
C 1
C 2
C 3
If you have any question, feel free to let me know.

Referencing Aggregated Column Value in Where Clause

Hello -
I'm trying to determine how I can accomplish the following in the most straightforward, efficient way.
Among other things, I'm selecting the following value from my table:
max(received_date) as last_received_dateI also need to evaluate the "last_received_date" value as a condition in my where clause. However, I can't reference my aliased "last_received_date" column value, and when I try to evaluate max(received_date) in the where clause, I get the "group function is not allowed here" error.
Does anyone know of a good workaround?
Thanks,
Christine

Hi,
Column aliases can be used in the ORDER BY clause: aside from that, they cannot be used in the same query where they are defined. The workarounds are
(a) define the alias in a sub-query, and use it in a super-query, like Someoneelse did, or
(b) repeat the aliased expression, as in the HAVING-clause, below.
Aggregate functions are computed after the WHERE-clause. (That explains why you can do things like
SELECT MAX (received_date) last_received_date_2008
FROM    table_x
WHERE   TO_CHAR (received_date, 'YYYY') = '2008';).
The HAVING-clause is like the WHERE-clause, but it is applied after the aggregate functions are computed, e.g.
SELECT    deptno
,         MAX (recieved_date) AS last_received_date
FROM      table_x
GROUP BY deptno
HAVING    MAX (received_date)    > SYSDATE - 7   -- Only show deptartments with activity in the last week

FSG report not printing column values on same line but sequentially

FSG report problem:
We have defined 2 FSG reports 'Balance Sheet - Total' and 'Balance Sheet - Detail'. Both reports have 3 column values, namely the value in Euro (our Functional Currency), the value in MUR - Mauritian rupees (our reporting currency) and the rate of exchange.
The report 'Balance Sheet - Total' displays these values for assets e.g.:-
EURO MUR Rate of exchange
Non-current assets
1. Intangible assets ? ? ?
2. Other investments ? ? ?
(note: ? represents a certain value)
The report 'Balance Sheet - Detail' displays values as follows :-
Account EURO MUR Rate of exchange
1. Property & Equipment
A10101 Building Cost ? 0.00 0.0000
A20105 Motor Veh Accum Dep ? 0.00 0.0000
TOTAL ? 0.00 0.0000
A10101 Building Cost 0.00 ? n/m
A20105 Motor Veh Accum Dep 0.00 ? n/m
(note: ? represents a certain value)
What we don't understand s why the 'Balance Sheet - Detail' report repeats the display of column values in MUR FOLLOWING the display in EURO, instead of displaying column values for EURO and MUR on the same line, just like in the case for 'Balance Sheet - Total'.
Is there anything in the definition of column set, row set or report set should I change?
Can anybody help. Thanks.
null

The problem is related to defining the column set properly. It is OK with the first report and needs modification for the second. Formatting is also important so that they appear in the same line(row). The columns need to be linked to the fileds and assignment to set of books is also important as mentioned by Rajsekhar

Tabular form query using column values delimiter

I wanted to know, if i can query a tabular block by entering the column values (primary key) as semicolon delimited and update required fields. Please let me know.
Requirement:-
User will enter 5 values as "AB1; AB2; AB3; AB4; AB5"
After entering I need to write a plsql code to query the tabular form as follows
PrimaryCol SecCol
AB1 IN
AB2 IN
AB3 OUT
AB4 IN
AB5 ON
Then I will update the columns accordingly.
Please help me.

You could put something like this in the WHERE-clause (assuming that :BLOCK.QUERYDATA contains your value AB1;AB2;AB3;AB4; )
INSTR (';' || PK_COLUMN || ';', ';' || :BLOCK.QUERYDATA || ';')>0Maybe you have to additionally eliminate space in :BLOCK.QUERYDATA

Column values as Page Header

Hi All,
I want to display some column values like Company_Name, Company_Address etc in the Page Header of the report. I am fetching these values from table in the query of my report. Can somebody tell me how I can do that?
I tried placing a repeating frame in upper area of margin in 'Main Section' of report. Source of the frame was Query group. It printed multiple headers on one page.
Waiting for your replies. Thanks in advance.
Regards
Mona

I think your query is return more then one record or u create query as child .
Create a query company name, address etc. as parent and other information as a child query, and link them with link tool.
Example
Q1. Select customer_no,name,address from customer (Parent)
Q2. Select customer_no, invoice_no, amount from invoices (Child)
If u created query like this
Select c.customer_no,c.name,c.address, i.invoice_no, i.amount
from customer c, invoices i
where c.customer_no=i.customer_no;
its return name and address for every record of invoices table.

Getting count of occurances of a string in a column value

Hi,
Is there a way to get the number of occurences of a string in a single column value?
Example:
CREATE TABLE STRING_CNT(X VARCHAR2(100));
INSERT INTO STRING_CNT(X) VALUES('OracleXXOracleXXOracleXXOracle');
Commit;
Now the string 'Oracle' is repeated 4 times in the inserted value. I would like to get this count using SQL.Can some one tell me how to get this?
I was asked this interesting question in an interview today.

hi 
u can get the occurrence of a string in text as
follow 
>
SELECT (LENGTH(x)-LENGTH(REPLACE(x,'Oracle', ' ' ))) 
/ LENGTH('Oracle') as 
Occurrence FROM STRING_CNT; 
 
Are you sure...? 
 
 
SQL> with STRING_CNT as
2 (select '1.Oracle2.Oracle3.' x
3 from dual)
4 SELECT (LENGTH(x)-LENGTH(REPLACE(x,'Oracle', ' ' ))) / LENGTH('Oracle') as Occurrence
5 FROM STRING_CNT;
OCCURRENCE

Repeated column in mapping error - Hibernate mapping

Hi, I am relatively new to using Hibernate. I have two tables which I have tried to map unsuccesfully.
Table 1:
Primary Key(Instrument) -> Generated using function.
Table 2:
Primary Key(Instrument) -> Referenced from primary key of table 1
Table 3:
Primary Key(Instrument) -> Referenced from primary key of table 2
Additional Column(Parent_Instrument) -> Referenced from the primary key of table 2
So, two columns in Table 3 have to be mapped to the primary key of table 2.
I have tried mapping them but am getting the following error:

I probably didn't explain it correctly. I am trying to populate these tables with data about financial instruments.
Table 2 and 3 share a primary key (INSTRUMENT). The primary key is generated in table 2, and the same value has to be later inserted into table 3. Sorry, I'm not following this at all. I don't think two tables should "share" a primary key. Both should have their own. Perhaps Table 3 would have a foreign key relationship with Table 2. OR the two tables should be one. But this notion of sharing doesn't sound right to me, and apparently Hibernate agrees. I think you have a bad design.
Table 2 has a one to many relation with table 3. Then they can't share a primary key. It's 1:m, which you can easily model with Hibernate.
(By many I mean it could be 0 as well, since hibernate does not provide a (one to 'maybe' one 'maybe zero) relation.Fine. Then it's a 1:m relationship. You've been thinking about it incorrect.
Table 3 has an additional column PARENT_INSTRUMENT which is a foreign key to the the primary key of table 2.No. Wrong.
Yes Instrument is financial in nature. However, I am not trying to model what you have spoken about above.Yes, I get it. Listen to Hibernate - your original idea is quite incorrect. Table 2 is 1:m with Table 3. Model it that way, and forget about this incorrect notion of "sharing a primary key". Give Table 3 its own auto generated key.

Better approach for checking column values between two different rows

)Hi Experts,
     I've provided sample data where I'm checking for just two columns viz brwr_short_name ,sic_code,but in real time
I've to check for 8 more columns so please suggest me with a better approach.
I appreciate your precious suggestions.

Hi,
Thanks for posting the CREATE TABLE and INSERT statements; that really helps!
Here's one wa. Like your 2nd approach, this uses a self-join:
WITH     got_r_num     AS
     SELECT ca_id
     ,     ROW_NUMBER () OVER ( PARTITION BY ca_id
                               ,                    fac_id
                         ORDER BY        ca_ver_num
                             )    AS r_num
     ,     brwr_short_name
     ,     TO_CHAR (sic_code)     AS sic_code
     ,     fac_id
--     ,     ...     -- Other columns (using TO_CHAR if needed)
     FROM     r_dummy
,     unpivoted_data     AS
     SELECT     *
     FROM     got_r_num
     UNPIVOT     INCLUDE NULLS
          (    txt
          FOR column_name IN ( brwr_short_name          AS 'BRWR_SHORT_NAME'
                        , sic_code               AS 'SIC_CODE'
--                        , ...     -- Other columns
SELECT       p.ca_id
,       p.fac_id
,       p.column_name
,       p.txt          AS previous_name
,       a.txt          AS after_modification
FROM       unpivoted_data   p
JOIN       unpivoted_data   a ON p.ca_id     = a.ca_id
                       AND p.fac_id     = a.fac_id
                     AND p.column_name     = a.column_name
                     AND p.r_num      = a.r_num - 1
                     AND p.txt || 'X' != a.txt || 'X'
ORDER BY a.r_num
;To include other columns, add them in the 2 places where I put the comment "Other columns".
Ca_ver_num can have any values, not just 2.00 and 3.00.
This will show cases where a value in one of the columns changed to NULL, or where NULL changed to a value.
There ought to be a way to do this without a separate sub-query like got_r_num. According to the SQL Language manual, you can put expressions in the UPIVOT ... IN list, but when I tried
...     UNPIVOT     INCLUDE NULLS
          (    txt
          FOR column_name IN ( brwr_short_name          AS 'BRWR_SHORT_NAME'
                             , TO_CHAR (sic_code)     AS 'SIC_CODE'
          )I got the error "ORA_00917: missing comma" right after TO_CHAR. Perhaps someone else can show how to eliminate one of the sub-queries.

Repeat Suppressed Value after Page Throw

Hello
I'm new to BI Publisher and have what I think is a simple problem that I can't solve and can't see a solution to in the forum so any help would be welcome.
I have a report which is essentially a simple, long table with three columns. The report is grouped by the first column, so that the value is suppressed after the first display. When the table breaks across a page the heading repeats fine, but I need to show the grouped value again on the first line. Is this possible?
Thanks
Ian

Hi Vetsrini!
Are you able to post the steps needed to prevent column values from repeating? I work on multiple networks so it's not possible to email you the files.
Thank you!
