Just a FYI regarding Case statements in ORacle 8i in pl/sql
Well..I saw numerous posts in this forum regarding not being able to do case statement within pl/sql. Well..you can do
that using dynamic SQL. IT works like a champ.
Hi,
Try first to (re)compile ll invalid objects. then
you can run:
select owner,type,count(*) from all_errors
group by owner,typeif you still have uncompiled objects, then report the different errors:
select * from all_errors...

Case Statement in Oracle Query.
Hello Oracle Gurus,
I need suggestion on whether I should use Case statement in Oracle queries.
I have a sql statement which inserts the data by selecting data from other table. While selecting the data I have put a logic in the select statement for one column which is something like this and there are some more similar statements in the same query.
CASE
WHEN (b.ACCOUNT = 'FIN' or b.ACCOUNT ='FIN ACC' or b.ACCOUNT like '%Global Eq%' or b.ACCOUNT like '%Flexible Bond%')
THEN
'MTM'
WHEN (substr(a.CTC,-3)='MTM')
THEN
'MTM'
WHEN (substr(a.CTC,-3)='AFS' or substr(a.CTC,-3)='HTM' OR substr(a.CTC,-3)='ACC' OR substr(a.CTC,-3)='HFI' )
THEN
'ACC'
ELSE
'OTH'
END,
I wanted to get an suggestion about how much performance issue can I have due to this in my insert statement.
Let me know if you need any other information.All comments are really appreciated.Hi,
It's depends on the joins how you have performed with source table, stats and existing of indexes. If the volume of data is high - in case of any performance issue - why can't you perform the required things of logical conditions of data and popualte in one cluster so - that you can fetch out the chunks of required information with better way and in support with indexes.
Let us know the ful query your working on

CASE statement in Oracle 8i PL/SQL
I'm in the process of doing an upgrade from 8i to 10g and have the necessary instructions in performing it. however, after running the pre upgrade tasks (run utlu102i.sql) to show the preupgrade information, i found out that there are some INVALID objects.
Miscellaneous Warnings
WARNING: --> Database contains INVALID objects prior to upgrade.
.... USER INGITRN has 1 INVALID objects.
.... USER INGIUAT has 3 INVALID objects.
.... USER OEMMON has 7 INVALID objects.
.... USER RE_ITF_USER has 11 INVALID objects.
.... USER SYS has 1 INVALID objects.
Would it be ok to proceed with the upgrade and ignore the warnings?
Also, as i checked the invalid object for SYS, it shows:
OWNER OBJECT_NAME OBJECT_TYPE STATUS
SYS UTL_RECOMP PACKAGE VALID
SYS UTL_RECOMP PACKAGE BODY INVALID
Further more, i tried to do a fix by invoking utlirp.sql and the same objects are showing up. Same thing shows when invoking utlrp.sql or even doing a manual compile for the affected objects. I later found out that CASE statements are not accepted in PL/SQL for Oracle 8i.
Can you help me fixed the issue on the invalid object?

Regarding case statement and decode function
Hi Experts,
I have question.....regarding case statement and decode statement....
Can you please explain me that which one will be efficient,to place in insert statement...
insert statement(
(case when ........then
case when ....then
else
end)
else
end)
or
insert statement(
case when.....then
decode(....)
else
end)
Can you people explain me which one is more efficient method?
Thanks in advance.......The are major differences to talk about in case of CASE vs DECODE, but performance wise both are pretty much the same.
Have a look at Tom's thread
Ask Tom "better performance - case or decode"
I would suggest to use CASE whenever possible. Don't worry about the performance part. -
Hi guys,
i am getting a very strange problem. i have score column. basis of this column i am sorting the dataand after it i am giving rank to it.
but for one employee it is not giving rank. giving null.so please any suggestion.
i am applying case statement for it.It can be because of case statement...Whats the purpose of case statement here ? plz elaborate..
Try removing case and check if you are getting same error -
can anyone tell me what to do to make the query below run in Oracle 8i.
thanks
select

else connum end
from namesI believe the confusion arises since CASE and other new functions and features in 8i - analytic functions, NVL2 scalar subquery ..., did not work in PL/SQL in 8i due to it having a different SQL parsing engine. A common work around was to put the offending SQL in a view or execute it as dynamic SQL where PL/SQL would use the database parser.

Please help!Oracle 8i doesn't support CASE into PL/SQL, so as Kamal said, create a view with the CASE, and use this view into your PL/SQL.

Doubt Regarding Merge Statement in Oracle
Hi,
I have an SP which takes 3 parameters Lets say
(in_empid, in_empname,in_age)
here in_empid corresponds to the empid ie primary key for update/insert
Now which of the approach will be better. Will there be problem in using Merge statements for updates/insert
1. Approach 1
Add one more flag in parameters in_action . Now if in_action = 'U' then write an update statement.If in_action='I' then write insert stmnt
2. Approach 2
write a merge stmnt as follows
merge into employee e using
( select in_empid, in_empname,in_age from dual ) b
on ( b.in_empid = e.empid)
WHEN MATCHED THEN
UPDATE SET e.ENAME = in_empname,
e.age = in_age
WHEN NOT MATCHED THEN
INSERT
VALUES (in_empid,in_empname,in_age) something like that
Which would be preferred? I mean is there any restriction that merge can be used only to merge 2 tables?what are the drawbacks of using Merge?
Regds,
SHi cd,
Thanks for the reply.
Actaully I was keeping the front-end code also in mind.
If we click an update button, then they will have to manage a flag till the end to say that transaction was update. whereas when its an insert of new record, they have to maintain a falg till end to imply that the transaction was insert.
I want to avoid this so that they need not maintain additional flag.
Hence I was thinking of using MERGE statement.
Will there be any problem in using merge for such scenarios?
Regds,

Help Regarding CASE Statement.
hey !
i m trying to apply COUNT to a column , with a particular condition.
like.
CASE
WHEN( A > B)
THEN COUNT(some column)
else '0'
end
but its not working.
can anyone tell me how to count only particular rows which satisfy the given condition in WHEN Clause.
i m trying to add many columns from different tables by joining them and then adding column one by one satisfying different conditions.
my final table looks like this.
items in stock-----|-----items_not_in_STock----|----Items_fully_in_stock
its something like this...!!!
secondly , what if i dont want any ELSE condition.
is it possible???I am not quite sure I understood your "requirement"...no tables, no sample data, no expected output...
can anyone tell me how to count only particular rows which satisfy the given condition in WHEN ClauseAssuming your requirement is above i.e. getting count of resultset based on different conditions, following might help you.

Need help converting Excel IF statement into CASE WHEN statement for Oracle
Hi,
Hope someone can help I have tried various ways of getting this to work, to no avail!
Bascially I have some figures that are minus figures, and I need to add them together to get a movement figure, but I need to treat the minus figures as minus, if that makes sense, rather than the usual... a minus and a minus makes a plus.
For example:- Budget Figure = -1% and Actual Figure = -68% so the movement needs to be -69%.
The IF statement I have been using in Excel is the following:-
=IF(FO110<0,(FP110-(IF(FO110=0,1,FO110)*-1)),FP110-IF(FO110=0,1,FO110))
Which when using the figures as above = -69%
Cell FO = The Budget Figure
Cell FP = The Actual Figure
However, when I created the CASE statement in Oracle, the figure in the query comes back as -0.67, which is oviously not what I want to happen when both actual and budget are minus figures; however when they are a minus and a plus, it works perfectly fine.
Any help on this would be most appreciated!
Kind regards,
AnnmarieHappy I did'n mess something up :)
Nevertheless, don't show it too much around because
case when budget < 0
then actual - case when budget = 0 /* will never happen */
then 1 /* will never happen */
else budget
end * (-1) /* -budget * (-1) remains only */
else actual - case when budget = 0
then 1
else budget
end
endso at least try the following (if case is more readable as decode for you). Let's hope it works as I don't have a Database at hand
case when budget < 0
then actual + budget
else actual - case when budget = 0
then 1
else budget
end
end Regards

SQL>Thank You for any help
BenOk, i looked at this a little harder and have some advice for you.
1) lose the dynamic SQL or use binds if you NEED to be dynamic.
EXECUTE IMMEDIATE 'SELECT MAX(SCH_ID) FROM FBT_SCHEDULE WHERE PAR_ID = ' || party_id || ''
INTO num;
should just be
SELECT MAX(SCH_ID) INTO num FROM FBT_SCHEDULE WHERE PAR_ID = party_id;
EXECUTE IMMEDIATE 'select to_char(sysdate,' || '''' || 'DAY' || '''' || ') from dual'
INTO today;
should just be
today := to_char(sysdate, 'DAY');I'm also having a hard time following the logic, you have a party_id that doesn't change, yet you query based on that repeatedly inside your loop. It should be outside the loop.
In all likelyhood, you could do this in no procedural code, something to strive for if you have spare cycles.
Oh yeah, if you absolutely MUST use dynamic sql (you posted example code and my non-dynamic approach doesn't apply) then you MUST use bind variables.
EXECUTE IMMEDIATE 'SELECT SCHEDULE_DATE FROM FBT_SCHEDULE WHERE SCH_ID = ' || num || ''
INTO day_rec;
would be
EXECUTE IMMEDIATE 'SELECT SCHEDULE_DATE FROM FBT_SCHEDULE WHERE SCH_ID = :my_bind_variable' INTO day_rec USING num; -

[Oracle 8i] Handling null in case statement
The following bit of my query is causing the error 'inconsistent datatypes':
CASE
WHEN b.days_diff < 0
THEN plan_start
ELSE plan_start + b.days_diff
ENDThe problem is that b.days_diff can be null.
I've tried to work around this, by using the NVL statement and by nesting 2 case statements to try to deal with the null, but can't seem to work around it.
Does anyone have anything else I can try?Apologies...internet server went down yesterday...
I've had this issue before with my database. When I look at user_tab_columns, it says plan_start is a date. However, I have had to use TO_DATE in the past with it to get some things to work. It's very odd, and I have no idea why it's like that.

Hi all,
I have to compare the value of a varchar variable using a CASE statement and display the corresponding output.
But when the following code is being executed, and i gave the value of dayrange as anything other than number, i am getting the error;
The daysrange variable can be a number or a string (Hence i declared it as a varcahr2)
Error report:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at line 5
06502. 00000 - "PL/SQL: numeric or value error%s"
*Cause:
*Action:
declare
daysrange varchar2(10):='abc';
x varchar2(100);
begin
CASE WHEN DAYSRANGE = 1 THEN x := 'LD';
WHEN DAYSRANGE BETWEEN 2 AND 7 THEN x := 'LW';
WHEN DAYSRANGE BETWEEN 8 AND 30 THEN x:= 'LM';
WHEN DAYSRANGE BETWEEN 31 AND 90 THEN x:= 'L3M';
WHEN DAYSRANGE BETWEEN 91 AND 180 THEN x:= 'L6M';
WHEN DAYSRANGE BETWEEN 181 AND 365 THEN x:= 'LY';
WHEN DAYSRANGE BETWEEN 366 AND 730 THEN x:= 'L2Y';
WHEN DAYSRANGE > 730 THEN x:= 'O2Y';
ELSE x:='x:= x';
END case;--DATERANGE
exception
when case_not_found then
x:='something';
dbms_output.put_line(x);
end;

... The daysrange variable can be a number or a string (Hence i declared it as a varcahr2)That's usually not a good design. It would be better to have two variables (or columns) if necessary, a VARCHAR2 and a NUMBER.
If you can't change the design, then test daysrange, and then do different things depending on whether it is a number or not.
For example:
declare
daysrange varchar2(10) := '17';
daysrange_n NUMBER;
x varchar2(100);
begin
IF REGEXP_LIKE (daysrange, '^\d+$')
THEN
daysrange_n := TO_NUMBER (daysrange);
x := CASE
WHEN daysrange_n > 730 THEN 'O2Y'
WHEN daysrange_n > 365 THEN 'L2Y'
WHEN daysrange_n > 180 THEN 'L1Y'
WHEN daysrange_n > 90 THEN 'L6M'
WHEN daysrange_n > 30 THEN 'L3M'
WHEN daysrange_n > 7 THEN 'LM'
WHEN daysrange_n > 1 THEN 'LW'
WHEN daysrange_n = 1 THEN 'LD'
ELSE x -- If necessary
END;
END IF;
...The tests in a CASE expression are done in order. The n-th WHEN condition is tried only after conditions 1 through n have failed. That's why we can saY, for example,
"daysrange_n > 365" instead of
"daysrange_n BETWEEN 366 AND 730". If the 2nd test is even being performed, we know that the 1st test failed, and that daysrnage_n is not > 730.
I'm not saying that you have to write CASE expressions like this, or that it's necessarily better. You should know that it's possible, then choose whichever way makes the most sense in this situation.
