Not sure of your requirements but this mayhelp reduce your code;
<untested>
SUM (
   CASE
   WHEN tt.transactiontypecode IN
      ('WITHDRAWAL_CHECK_FEE', 'REJECTED_ACH_LOAD_FEE', 'WITHDRAWAL_ACH_REV', 'WITHDRAWAL_CHECK_REV',
       'WITHDRAWAL_CHECK_FEE_REV', 'REJECTED_ACH_LOAD_FEE_REV', 'OVERDRAFT_FEE_REV','STOP_CHECK_FEE_REV',
       'LOAD_ACH_REV', 'OVERDRAFT_FEE', 'STOP_CHECK_FEE')
   THEN th.transactionamount
   ELSE 0) feeAlso, you might want to edit your post and use [pre] and [/pre] tags around your code for formatting.

How to write the query to find the duplicate rows?

Hi,
How will I find the duplicate rows in the table?
I have a table called ITEM
Select item_no,mfg_id from item
Item Mfg_ID
178 06278
178 06589
238 5489
289 7895

Now I want to find only the duplicate rows i.e.,178 & 289 is coming twice.
How will get the all duplicate rows in the table?

How to Find the Query used by the Workbook ?

Hi ,
I am currently involved in trouble shooting a work book where some master data values are not being displayed.
How do i find, which Query the work books is using ? or Let me know as to how should i proceed in solving the same .

Hi,
If you have access to BW Admin workbench... then choose the option metadatarepository(left side) of the BW admin workbench, search for the workbook(Technical name) and click on the "Network display dataflow" link.
If you want to know the relationship between workbook and the queries:
Check table RSRWORKBOOK which contains the WORKBOOKID and the GENUNIID.
Table RSRREPDIR contains GENUNIID, query name RNAME, AUTHOR, LASTUSER, INFOCUBE
Table RSRINDEXT contains the WORKBOOKID and workbook TITLE
You should join the tables by GENUNIID and select in RSRREPDIR the rows that have COMPTYPE='REP' for queries and object version active/modified.
With this information an infoset query can be created to list all workbook-query-user relationship (and even the query-infocube relationship).
Hope this helps u...
Regards,
KK.

How to write this query using correlation subquery or non exists clause

-- Tables description.
--step-1- 4 employees present in EMP table.
--step-2- each employee having 1 country_no in EMP_DOCS table.3 employees having same country_no(i.e emp's 1,2,3)
--step-3- 1 emp document can have multiple items.In this case each employee having one each in the EMP_ITEMS table.
--step-4- 1 EMPLOYEE can have Multiple Documents so we have a relation between EMP_ITEMS and DOCUMENT_ITEMS.whatever items present in EMP_ITEMS those items will be inserted into DOCUMENT_ITEMS.so we have a item-item relation.
--so we stored EMP_ITEMS id in EMP_ITEMS_REF_ID_1 of DOCUMENT_ITEMS table.
-- step-5- DOCUMENT-INVOICE has 1-1 relation once invoice is created we stored invoice id in DOCUMENT table.
--This is the requirement.Let's say in this example 3 employees are using same country_no and 4th employee is using another country_no
--which is not used by other 3 employees.
--Condtion-1:
--if all of the employees have created INVOICE which is using same country_no of different country_no then the query should display all records.
--Condition-2:
--if any one of the employee not created INVOICE which is using same country_no of other employees then remaining employees also should not come in the query
-- even though invoice is created by other employees.
--Condition-3:
--if any one of the employee not created even DOCUMENT which is using same country_no of other employees then remaining employees also should not come in the query
-- even though invoice is created by other employees.
I hope I explain the conditions clearly.if you understand well by looking at the data i posted below may i know what is the final result should be displayed?

How to split the query using rowid

can anybody pls tell me logic to spliting the sql query by using rowid through dba_extent...

Using Parallel Execution will help if it is the DB that is the bottleneck, but if on the other hand it is your client program that is the bottleneck (and the DB is supplying the data as fast as it can) then splitting the query into rowid ranges and having multiple extract clients will have benefit.
1) Each extract process should read DBA_EXTENTS for the given object and select the extents it should process (Ideally 1 extract process per Data File).
2) Use the DBMS_ROWID.ROWID_CREATE to build low and high rowid ranges based on the BLOCK_ID and BLOCKS from DBA_EXTENTS. Note you will also have to look up the DATA_OBJECT_ID for the Table in question.
Note. Because we won't know the Row Number of the last row in the last block, use the first row in the first block after the last block and then use <.
3) Add the ROWID hint to your query.
4) Use >= "Low Rowid" < "High Rowid" (Note. use of < rather than <=)
This method is only safe when the table in question is not being updated, as each extract process will be running its own read consistent view, and so there is a danger that transaction updating 2 rows could have only half of the update extracted (if 1 row was in 1 extent after it had been extracted and another row was in another extent before it was extracted).
Only 1 rowid range can be passed to the query at a time (you can supply more, but a ROWID access will no longer be performed, it will simply to a FTS).

The index doesn't help for this query, so it's not used.
The main purpose of indexes is the help find a small number (like 1) of rows quickly. You're asking for all rows; getting each one through the index would be slower than just getting all of them directly.
Sometimes (but not here) the index can be used instead of the table, when the index contains all the data you need from the table. An index on cust_id doesn't tell you anything about any other column, such as cust_name. Since you asked to have all columns displayed, it has to fetch data from the table, not the index.

How to write a query use between two months

Hello,
I have two views v1 and v2. Both have two columns c1 and c2: c1 with mon-yyyy format, c2 is a number. I am writing a query like this;
select v1.c2, v2.c2 from v1, v2
where v1.c1 = v2.c1 and v1.c1 between to_date('Jan-2011','mon-yyyy')
and to_date('Dec-2011','mon-yyyy')
i got: ORA-01858: a non-numeric character was found where a numeric was expected
V1 and V2 value are like these:
Mon-2011 89
Feb-2011 33
Mar-2011 45
Apr-2011 98
How to make it work.
Thanks for your help.
Jen

Hello Jen Hu,
Try this:
with t as ( select 'feb-2011' as c1, 33 as nr from dual union
select 'mar-2011',45 from dual union
select 'apr-2011',98 from dual union
select 'jun-2011',86 from dual union
select 'jul-2011',78 from dual union
select 'aug-2011',87 from dual union
select 'sep-2011',68 from dual union
select 'oct-2011',56 from dual union
select 'nov-2011',68 from dual union
select 'dec-2011',55 from dual union
select 'jan-2012',54 from dual
) SELECT * FROM T
where to_date(c1,'mon-yyyy') between to_date('aug-2011','mon-yyyy') and to_date('dec-2011','mon-yyyy');@Tauceef:

You have to store full date, the conversion you are doing to_date('jan-2011','mon-yyyy') is not at all accepted, this is where you are getting that error.

Why not? Have you tried:
select to_date('jan-2011','mon-yyyy') from dual;Once you convert the character string into date it is easier to compare!
I agree with @clcarter's point:

Firstly, if you want to compare dates, use a DATE datatype, not varchar2. If the varchar2 has invalid dates you'll have all sorts of trouble. 'Feb-31-2011' is a perfectly valid string. But its not a date.

But if you have better mechanism of valid string input as in here:

then problems of invalid string input are minimized!
Hope it helps!

Hi,
One thing I understood my your issue is you want to perform, execution of query once or fetch the results sets my minimizing the number of times executions of queries. It would be hard for us to check in this way, atleast provide some temporary data and some business rules. Only I can IN, >, < (queries logical conditons on inner query)

1st query --> SELECT STATEMENT Optimizer=ALL_ROWS (Cost=6 Card=8 Bytes=416)
2nd query --> SELECT STATEMENT Optimizer=ALL_ROWS (Cost=16 Card=2 Bytes=156)
My queries are:
1) performance wise which query is better?
2) how do i make the 1st query to use an index
3) is there any other method to get the same result by using any index
Appreciate your immediate help.
Best regards

Hi William
Nice...it works.. I have added "o_id" and "o_no" are in part of the index
and now the query uses the index
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=2 Card=8 Bytes=416)
1 0 UNION-ALL
2 1 INDEX (FULL SCAN) OF 'IDX_TEST_S_ID' (INDEX) (Cost=1 Card=4 Bytes=208)
3 1 INDEX (FULL SCAN) OF 'IDX_TEST_S_ID' (INDEX) (Cost=1 Card=4 Bytes=208)
Statistics
7 recursive calls
0 db block gets
21 consistent gets
0 physical reads
0 redo size
701 bytes sent via SQL*Net to client
507 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
8 rows processed
But my questions are:
1) In a where clause, if "<>" condition is used, then, whether the system will use the index. Because I have observed in several situations even though the column in where clause is indexed, since the where condition is "like" or "is null/is not null"
then the index is not used. Same as like this, i assumed, if we use <> then indexes will not be used. Is it true?
2) Now, after adding "o_id" and "o_no" columns to the index, the Execution plan is:
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=2 Card=8 Bytes=416)
1 0 UNION-ALL
2 1 INDEX (FULL SCAN) OF 'IDX_TEST_S_ID' (INDEX) (Cost=1 Card=4 Bytes=208)
3 1 INDEX (FULL SCAN) OF 'IDX_TEST_S_ID' (INDEX) (Cost=1 Card=4 Bytes=208)
Before it was :
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=6 Card=8 Bytes=416)
1 0 UNION-ALL
2 1 TABLE ACCESS (FULL) OF 'TEST_TABLE' (TABLE) (Cost=3 Card=4 Bytes=208)
3 1 TABLE ACCESS (FULL) OF 'TEST_TABLE' (TABLE) (Cost=3 Card=4 Bytes=208)
Difference only in Cost (reduced), not in Card, Bytes.
Can you explain, how can i decide which makes the performace better (Cost / Card / Bytes). Full Scan / Range Scan?
On statistics also:
Before:
Statistics
52 recursive calls
0 db block gets
43 consistent gets
0 physical reads
0 redo size
701 bytes sent via SQL*Net to client
507 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
8 rows processed
After:
Statistics
7 recursive calls
0 db block gets
21 consistent gets
0 physical reads
0 redo size
701 bytes sent via SQL*Net to client
507 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
8 rows processed
Difference in recursive calls & consistent gets.
Which one shows the query with better performance?
Please explain..
Regards
Muthu

How to write sql query that display comma suppurated result using Group by

Hi,
I am having data like bellow ,
Above result got from joining two tables VMTAGroupClient,VMTAipNames .
Query i have written to display above result is,
select vgc.VMTAGroupId,vn.VMTAName from VMTAGroupClient vgc inner join VMTAipNames vn
on vgc.VMTAID=vn.VMTANameID group by vgc.VMTAGroupId,vn.VMTAName
using the VMTAGroupId column how to write query to display result result like,
VMTAGroupID VMTAs
1 VMTA1,VMTA3
2 VMTA2,VMTA4,VMTA5
Regards,
Anwar Shaik

Satheesh,
Here in my case data need to read from two tables VMTAGroupClient, VMTAipNames.
VMTAGroupId is in one table and VMTAName column in some other table.Iin both the tables VMTAID is common.
Please check the above result displayed data from two tables.
can we write same query using join?
