How to use CASE stmt in Where clause

Hi,
How to use CASE stmt in WHERE clause?. There's no difference between how a CASE expression is used in a WHERE clause, and how it is used in any other clause. CASE ...

CASE expressions aren't needed in WHERE clauses very much. The reason CASE expressions are so useful is that they allow you to do IF-THEN-ELSE logic anywhere in SQL. The WHERE clause already allows you to do IF-THEN-ELSE logic, usually in a more convenient way.
I need the code.So do the peple who want t help you. Post a query where you'd like to use a CASE expression in the WHERE clause. Post CREATE TABLE and INSERT statements for any tables used unless they are commonly available, such as scott.emp). Also, post the results you want from that sample data, and explain how you get those resuts from that data.
See the forum FAQ {message:id=9360002}
Please send me as early as possible..........As mentioned bfore, that's rude. It's also self-defeating. Nobody will refuse to help you because you don't appear pushy enough, but some people will refuse to help you if you appear too pushy.

How to use case when function to calculate time ?

Dear All,
May i know how to use case when function to calculate the time ?
for the example , if the First_EP_scan_time is 12.30, then must minus 30 min.
CASE WHEN FIRSTSCAN.EP_SHIFT <> 'R1' AND FIRSTSCAN.EP_SHIFT <> 'R2'
THEN ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF((CASE WHEN SHIFTCAL.EP_SHIFT = 'N1'

ELSE LEFT(FIRSTSCAN.EP_SCAN_DATE ,8) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','') END),12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0 - 0.25) AS FLOAT),2)

Do not use computations in a declarative language. This is SQL and not COBOL.
Use a table of time slots set to one more decimal second of precision than your data. You can now use temporal math to add it to a DATE to TIME(1) get a full DATETIME2(0). Here is the basic skeleton.
CREATE TABLE Timeslots
(slot_start_time TIME(1) NOT NULL PRIMARY KEY,
slot_end_time TIME(1) NOT NULL,
CHECK (start_time < end_time));
INSERT INTO Timeslots --15 min intervals
VALUES ('00:00:00.0', '00:14:59.9'),
('00:15:00.0', '00:29:59.9'),
('00:30:00.0', '00:44:59.9'),
('00:45:00.0', '01:00:59.9'),
('23:45:00.0', '23:59:59.9');
Here is the basic query for rounding down to a time slot.
SELECT CAST (@in_timestamp AS DATE), T.start_time
FROM Timeslots AS T
WHERE CAST (@in_timestamp AS TIME)
BETWEEN T.slot_start_time
AND T.slot_end_time;

How to use CASE or DECODE in this?

Hi , I have a query like this
AND ...smthng
AND --smtg
AND age BETWEEN ....For the last AND clause for age column, I have the values passed from IN param of this SP in form of strings
'0-30', '31-60', '61-90', and '91+'. The IN param is of course VARCHAR2.
What I want to do in this AND clause
e.g. for age range '0-30', the AND clause should be
AND age BETWEEN ( if this range is '0-30' then ) 0 AND 30 ( if range is '31-60') then BETWEEN 31 AND 60.. and so on...
However this BETWEEN will work till 61-90 range but for 91+ , there is no upper bound so it should be
AND age>91
Now , i am not sure how to achieve this both BETWEEN and '>' clauses in the same AND statement.
DECODE will not work and am not sure how to use the CASE in this situation as even that can not solve this issue.
Dont want to make the last AND clause dynamic
Please suggest me how to do this.
Thanks,
Aashish
Edited by: Aashish S. on Oct 21, 2011 6:01 PM

A third alternative would be to choose a suitably large value as a high end for the 91+ group and use something like:
age between to_number(CASE WHEN instr(:param, '+') = 0
                              THEN substr(:param, 1, instr(:param, '-') -1)
                              ELSE substr(:param, 1, instr(:param, '+') -1) end) and
            to_number(CASE WHEN instr(:param, '+') = 0
                           THEN substr(:param, instr(:param, '-') +1)
                           ELSE '9999' END)John

How to use escape character in update statement.

Hi All,
I'm trying to update table using following sql update statement, but everytime it's asking me for the input due to the '&' value in below sql.
UPDATE xyz_xyz
   SET NAME = 'ABC & PQR'
WHERE ID = (SELECT ID
               FROM abc_abc
              WHERE NAME = 'C & PQR');Please let me know how to use escape character syntax or let me know if there is any alternative solution.
Thanks,
Vishwas

Hi,
By default, & marks a substitution variable name.
If you're not using substitution variables in that statement (or, if this is in PL/SQL, in that entire package or procedure) then the easiest thing to do is just diable substitution variables; then & will be a normal character:
SELECT DEFINE OFF
UPDATE xyz_xyz
   SET NAME = 'ABC & PQR'
WHERE ID = (SELECT ID
               FROM abc_abc
              WHERE NAME = 'C & PQR');
SET DEFINE ONIf you can't do that, then & is always taken literally if it comes right before a single-quote, so you could say:
UPDATE xyz_xyz
   SET NAME = 'ABC &' || ' PQR'
WHERE ID = (SELECT ID
               FROM abc_abc
              WHERE NAME = 'C &' || ' PQR');There is a SQL*Plus "SET ESCAPE" command, too, but if you use it, you have to worry about whether the escape character is to be taken literally or not.
SET   ESCAPE \Yet another alternative is to make some other character, such as ~, mark the substitution variables:
SET DEFINE ~Read all about them in the SQL*Plus manual.

How to use, Case function and Filter in Column Formula?

Hello All,
I am using case function and also would like to filter value to populate.
Below is showing error :
case
when '@{Time}' = 'Year' then "Time"."Fiscal Year"
when '@{Time}' = 'Quarter' then "Time"."Fiscal Quarter"
when '@{Time}' = 'Month' then FILTER ("Time"."Fiscal Period" USING "Time"."Fiscal Period" NOT LIKE 'A%')
else ifnull('@{Time}','Selection Failed') end
Thanks, AK

when '@{Time}' = 'Month' then FILTER ("Time"."Fiscal Period" USING "Time"."Fiscal Period" NOT LIKE 'A%')I dont think Filter this works here or any other data types except number.
Try to use option Column's->Filter->Advanced->Convert this filter to SQL

How to use case when statements in ODI

I need to put conditional logic before DVM look up in ODI. In the expression editor I put the following statement:-
CASE WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='RCS' THEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME=EBIZ_CELL.CELL_DATA
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='FDC' THEN CONCAT(POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME,POC_JOURNAL_TEMP_SOURCE_TBL.BOOK_CODE)=EBIZ_CELL.CELL_DATA
END
It did not work,
Under Operators ->All Executions, found the error:-
905 : 42000 : java.sql.SQLException: ORA-00905: missing keyword
The description in Session Task contained:-
select
     C1_JOURNAL_TEMPL
from     APPS.POC_JOURNAL_TEMP_SOURCE_TBL POC_JOURNAL_TEMP_SOURCE_TBL, APPS.C$_0POC_JOURNAL_TEMP_TARGET_TB
where
     (1=1)
And (CASE
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='RCS'
THEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME=C2_CELL_DATA
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='FDC'
THEN CONCAT(POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME,POC_JOURNAL_TEMP_SOURCE_TBL.BOOK_CODE)=C2_CELL_DATA
END)
Checked the above code in PL/SQL Developer but it gave errors.
In PL/SQL developer tried to check a simple query using case-when but even that is giving errors in the case-when portion.
The query is as follows:-
select phase_code, accounting_period, sum(eff_cc) as BD_Eff_QTD
from prj_detail
where
case POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME
when 'EXT'
then
1
when 'RAC'
then
2
when 'XXX'
then
3
else
end
I would like to know what is wrong with the above code.
Please let me know what is the correct way of using case-when in PL/SQL as well as in ODI.

Your ODI case statement and PL/SQL Case statement both looks confusing.
You are writing case statement under where clause which is not a good practise. If you want to implement logic like-
select a,b,c from <table>
where
when cond^n^ 1 then do 1
when cond^n^ 2 then do 2
then better you seperate your query for each filter and do a union, in other words-
select a,b,c from <table>
where cond^n^ 1
union
select a,b,c from <table>
where cond^n^ 2
If you are writing case staement to retrieve a value/column (EBIZ_CELL.CELL_DATA) then no need to include it under filter.
ODI case for column EBIZ_CELL.CELL_DATA will be:
CASE
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='RCS'
THEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='FDC'
THEN CONCAT(POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME,POC_JOURNAL_TEMP_SOURCE_TBL.BOOK_CODE)
END
Pl/SQL query-
select phase_code, accounting_period,
case POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME
when 'EXT'then 1
when 'RAC' then 2
when 'XXX' then 3
else 'default value' --- (if no else needed then can also remove else part)
end,
sum(eff_cc) as BD_Eff_QTD
from prj_detail
Suggested as per what is understood, hope it helps.

How to use case to replace the & in select statement

Did you see the where clause of your query??
6 where account_status like 'EXP%';do you realise that your query will always return those records for which value of account_status column starts with 'EXP'?
Why use CASE when it could be simply written like this :
SELECT username,
'EXPIRED AND LOCKED'
FROM dba_users
WHERE account_status LIKE 'EXP%'

How to use CASE with UPDATE?

Hi all. I'm trying to update multiple rows in a MS-Access
database using a single query, with different values for each row.
Here's a simplified example of the code:
<cfquery name="JustInCase" datasource="variables.DB">
Update Users
SET First_Name =
CASE WHEN ID = 1 THEN 'Nini' END,
SET Last_Name
CASE WHEN ID = 32 THEN 'Yumpi' END
</cfquery>
Trying to run something like this produces the following
error message:
[Macromedia][SequeLink JDBC Driver][ODBC
Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error
(missing operator) in query expression 'CASE WHEN ID = 1 THEN
'Nini' END'.
I realize this can easily be done using multiple queries, but
the actual code will contain many updates, and I would like to at
least test the possibility of improving performance using a single
query instead of multiple queries. I would greatly appreciate any
help with this - I've been trying all kinds of variations, and
nothing seems to satisfy emperor ColdFusion. Any ideas?

Case might be a verity tag but it is also a valid sql keyword
in many dbs. I use it in select clauses frequently and have seen it
used in where clauses.
The problem with the original query is that, it the value of
id is not 1, this part
SET First_Name =
CASE WHEN ID = 1 THEN 'Nini' END,
will cause a syntax error. For those values of 1 and 32, this
syntax will run, but will update every row in the table which might
not be the plan.
update users
set
case when id = 1 then first_name = 'Nini'
when id = 32 then last_name = 'Yumpi'
else first_name = first_name
end
ranger, your code will also fail if the value is neither 1
nor 32. You need a default case.

yours sincerely

update trips t

1)are these both query same and correct if i want to upate all rows.
2) some body said following two query are different
if there is any theory then pls tel me. because i have to use rownum<2 to get the top most row rather than distinct
in few cases
at some other places.

How to use one form to update two tables

How can I do that? HTMLDB wizard or form on table doesn't give me an option to use more than one table in a form or I don't know about it. I created new process which redirects the form to another page after submitting the form. On the second page I created new process which uses the same variables from the previous form page. This process runs on page load before header but it is just not working right.
So, what is the proper way to update two tables with the same form fields?

Hello Vikas,
"The Automatic Row Fetch and Automatic DML processes are a pair, you can't have one without the other."
Are you sure about that? I have a page, which populate some of the items from TableA, using manual select statement, and after the user input, save some of it in TableB, using Automatic DML. No ARF in this process and it seems to work just fine. Come to think of it, what about a simple form, populated entirely by the user input, and then being saved to the db, using Automatic DML? No ARF here also.
For the problem in hand, if you can't have more then one Automatic DML per page, I think that the simplest solution will be to define a pl/sql process, with two INSERT statement to the two different tables.
Regards,
Arie.
