Urgent-Help in SQL

Hi All
I have used the Case statement in my select query which is as:
SELECT LOTNO,CHIPTYPE,QUANTITY,CASE WHEN (LOTSIZE-QUANTITY)>=0 THEN to_char(LOTSIZE-QUANTITY) ELSE 'Error in Lot Size Entry' END AS REMAINING FROM TEMP_QTYCHIPWISE ORDER BY LOTNO
This query is working fine in Oracle9i but giving error in 8i.
What could be reason behind it.
Regards
Manpreet

This is pasted direct from my sqlplus window:
Connected to:
Oracle8i Release 8.1.7.0.0 - Production
JServer Release 8.1.7.0.0 - Production
SQL> select case when dummy = 'X' then 1 end from dual;
CASEWHENDUMMY='X'THEN1END
1
What error are you getting ?
Is your sql embedded in another tool ? Tools do not always support the latest database features.

Very Urgent Help , ABAP SQL Query

Guys,
Please suggest.I have a table(custom_table1) with a field say A which is of date type = c and length = 9. And i want to query this table.Following is the query.
Select substr(A,0,5) B C into itab From table custom_table1
where b = ( select b from cusstom_table2 )
and substr(A,0,5) = Input_A.
That is i want to equate an Input_A (which is of 5 character length) with field A (only first 5 character of the 9 length). But it seems the query is wrong. Kindly help ,very urgent
Thanks

Thanks guys, U have helped me to fill up the where condition as
but what about the column A in the select query ?I need only 5 characters from the field populated into Itab.
CONCATENATE srch_str '%' INTO srch_str. -- bcos i want it to be 'InputA%'
Select Substr(A,0,5) , B C Into Itab From CustomTable 1 where B = (Select B from customtable2) and A Like SrchStr
Is there any means i can populate only the 5 characters from the select field A into Itab without using Substr (becos it doesnt work) ? Please help.

Urgent HELP required on forming the Matrix of data using PL/SQL

Hi All,
I'm new to this thread and require your urgent help in this regard.
I've got a requirement for building a 5000 X 5000 matrix using PL/SQL. My original data tables have 5000 rows each and I need to do a correlation analysis using this data and need to store in a physical table and not in-memory. Is this feat achievable using mere PL/SQL? I understand that Oracle DB has a limitation of 1000 columns(but not sure) and hence I'd like to know whether there is any work-around for such scenarios. If not, what are the other alternative method(s) to achieve this feat? Do I need to use any 3rd party tools to get this done? An early reply from the experts is highly appreciated.
Thanking you all Gurus in advance.
Rgds

Welcome to OTN!
I'll get to your quesiton in a moment, but first some welcome information. Many OTN posters consider it impolite to mark threads as "urgent". We are volunteers and have jobs of our own to do without people we don't know making demands. You are brand new and deserve some patience but please understand this. It is very likely before I finish this post someone will complain about the word "urgent" in your subject.
On to more interesting things :)
You can do the matrix, but are out of luck with a 5000 x 5000 table because Oracle only allows 1000 columns per table. There are ways to work around this.
How do do the matrix depends on what you want to do. You can do this different ways. You can create a table beforehand and use PL/SQL or simple SQL to populate it, or use the CREATE TABLE AS syntax to create and populate it in one step if you can get the underlying SQL to work the way you want, something like
create table my_table as
select a.*, b.*
from table1 a, table2 bcan populate a matrix from 2 tables with an intentional cartesian join (the WHERE clause was left out intentionally, provided your data is already in the data base.
If not you can use a PL/SQL routine to populate the data.
There are a couple of ways to solve the 1000 column limit. The easiest way might be to have 5 collections of 1000 columns each. A more complicated but more elegant soltion would be to have nested collections, allowing 2 colliections that you can loop through - a collection of collections. Nested collections can be hard to work with. A third way would be to use nested tables in the database but I personally do not like them and the insert, update, and delete statements for nested tables are hard to use.
I'm not going to give a code example because I am not sure which solution is best for you. If you have further questions post them.

Urgent help needed... PL/SQL Insert statement

Hi...
I need some urgent help on this project. I have a 2 column table with values that need to be inserted into another existing table which has a sequence.
This is the 2 column table:
FUND YEAR
29587 05
29587 07
Existing table:
Name Null? Type
LIST_ID NOT NULL NUMBER(6) -- This is a sequence
WEB_USER_ID NOT NULL VARCHAR2(10)
RESOURCE_TYPE NOT NULL VARCHAR2(8)
LIST_TYPE NOT NULL VARCHAR2(10)
LIST_NAME NOT NULL VARCHAR2(50)
LIST_CODE_1 NOT NULL VARCHAR2(6) -- FUND from table above
LIST_CODE_2 NOT NULL VARCHAR2(6) -- YEAR from table above
LIST_CODE_3 NOT NULL VARCHAR2(6)
LAST_UPDATED_DT NOT NULL DATE
LAST_UPDATED_BY NOT NULL VARCHAR2(10)
LIST_CODE_4 NOT NULL VARCHAR2(20)
The columns from table 1 (FUND, YEAR) correspond to columns (LIST_CODE_1, LIST_CODE_2) in table 2. The column LIST_ID is a sequence. I can put in sysdate for LAST_UPDATED_DT and my initials SN for LAST_UPDATED_BY. This is going to be for 2 unique WEB_USER_IDs which would be in the WHERE clause. I will be inserting 2200 rows for each id. A single insert statement would look like this -
INSERT INTO EXISTING_TBL (list_id,web_user_id,resource_type,list_type,list_name,list_code_1,list_code_2,list_code_3,list_code_4,last_updated_dt,last_updated_by) VALUES ('470027','WEBUSER','GL','FUNDFYF',' FUND BALANCE SUM','12010','01',' ',' ',{ts '2010-5-19 10:16:9'},'SN')
How would I do this to insert the 2200 values from my 2 column table to the existing table?
All help is greatly appreciated!!
SN

Hello ,
I think this will work

Hi,
if you want to transform something to something else, you should declare, what is your source.
I would prefer to use plain XSL-Transformations, because you have a lot more options to transform your source and you can even better determine, how your output should looks like.
Kind regards,
Hendrik

Hi dears,
i need further assistance from your side, i have restarted the server, but the same problem.
as there a way to drop and re-create a system tablespace? since the file 34 belong to system tablesapce.
