Can you use boolean function in where clause

Hi,
I have a boolean function. Is it possible to use it in where clause of query.
Eg;
is_prime(13) returns boolean
select 1 from dual where is_prime(13)

What about something like this
Create or replace function boolret(id number) return boolean as
begin
If id <10 then
return true;
elsif id>10 and id<100 then
return false;
else
return null;
end if;
end;
1 declare
2 id_cat boolean;
3 begin
4 id_cat:= boolret(8);
5 dbms_output.put_line(id_cat);
6* end;
SQL> /
dbms_output.put_line(id_cat);
ERROR at line 5:
ORA-06550: line 5, column 2:
PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
ORA-06550: line 5, column 2:
PL/SQL: Statement ignored
It seems PL/Sql doesn't have any datatype like Boolean,But it handles Boolean like datatype.

Can't have aggregate function in WHERE clause clause

Dear all,
I've created object in BO XI 3.1 Designer with following criterias:

Can I use SYSDATE in the WHERE clause to limit the date range of a query

Hi,
Basicaly the subject title(Can I use SYSDATE in the WHERE clause to limit the date range of a query) is my question.
Is this possible and if it is how can I use it. Do I need to join the table to DUAL?
Thanks in advance.
Stelios

As previous poster said, no data is null value, no value. If you want something, you have nvl function to replace null value by an other more significative value in your query.<br>

Can you help me with the WHERE clause? Any issue with this code block?

Hi,
I am looking for blogs or any document on how to implement a Lookup during data loads in BW.
The problem is that all those that I find on this site are mostly about u201CLookup in XIu201D
I have read bits and hints on different postings on this site and this is the best I could do for the scenario shown below:
I need to add the Chars: Char1, Char2, Char3 to CubeX
so that I can display the data for these 3 Chars in a report.
Char1 and Char2 are filled in ODS12 and Char3 is filled in Cube3.
Can you help me write a routine so that while loading data to CubeX, it will read Char1, Char2, Char3 from ODS12 and Cube3; and make them available in CubeX?
This is my attempt so far: continue:
u201C----
select /bic/Char1 from /bic/ODS12
select /bic/Char2 from /bic/ODS12
select /bic/Char3 from /bic/Cube3
into result
WHERE u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026u2026
and objvers = 'A' .
end select.
u201C----
1. What should be my WHERE clause?
2. In the select statement, by studying samples on this where should there be an u201CMu201D in front of the ODS? e.g. select /bic/Char1 from /bic/MODS12
If so, what is the significance and the other options?
3. Should this code be in the Start routing of CubeX? Or any other possible location? Also, in the start routine does it matter where within the start routine this code needs to be placed?
4. Can you please fix this code and add any lines I may be missing?
Is what I am looking to do refer to as u201Cdoing a lookupu201D?
Thanks

Hi,
The best thing for you to do is start over. Start as small as possible, then take baby steps.
Pick one of the tables; fcr perhaps, and write a query that just uses that table, like this:
SELECT    *
FROM       apps.fnd_concurrent_requests     fcr
WHERE       fcr.actual_start_date          >= TRUNC (SYSDATE)
AND       fcr.actual_start_dt          < TRUNC (SYSDATE) + 1
;(I think this is what you meant to do when you said "... LIKE SYSDATE".)
Make sure this little query gets credible results. When that tiny query is working perfectly, add another line or two. You can cut and paste code from what you posted, if that helps you.
If you get stuck, post the last version of your code that worked perfectly, and the latest version (only a line or two bigger) that has the problem. Describe what the problem is. If you get an error, post the complete error message. In any event, post CREATE TABLE and INSERT statements for all the tables and columns needed to run the query, and the results you want to get from that query.
When you post any code, format it, so that how the code looks on the screen gives some clues about how it is working.
When you post any formatted text on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
If you going to use the AVG function in the sub-query, then you probably need to do a GROUP BY in the sub-query.
If you're not using any aggregate functions (like AVG) in the main query, then you probably don't want to do a GROUP BY in the main query.
I know this is a lot of work. I'm sorry. If there was an easier way, I wouldn't ask you to do all this.

Using function in where clause

I have created a function as follows
create or replace FUNCTION get_codes RETURN varchar2 IS
scodes varchar2(50) := 'A1,A2';
BEGIN
scodes := '('''||REPLACE(scodes,',',''',''')||''')';
return scodes;
END;
this function returns ('A1','A2')
now i want to use this in where clause, both below statements fetches no rows
select * from tablea where code in (select get_codes from dual);
select * from tablea where code in get_codes;
but the following will fetch rows
select * from tablea where code in ('A1','A2')
how to use function in where clause
Thanks

Hi,
The code that works:
where code in ('A1','A2')is testing whther code is either of two 2-character strings, A1 or A2.
The ones that don't work, such as:
where code in get_codes;are comparing code to one 9-character string: 'A1','A2', where characters 1, 4, 6 and 9 are single-quotes. (The function can only return one value.)
You can use dynamic SQL to embed that 9-character string in part of your query, where it will be interpreted as two 2-character strrings.
[Oracle Base|http://www.oracle-base.com/articles/misc/DynamicInLists.php] and AskTom have good pages on the subject of dynamic IN-lists.
Of you can use INSTR or LIKE:
where INSTR ( get_codes
, '''' || code || ''''
) > 0

Clarification on using function in where clause of oracle sql query

I have an issue in regarding function using where clause of sql query..
We are facing performance issue while executing query, so in what ways to improve the performance of the query which i have posted below.
select col ,case when my_function(parameter)
from tab1 a ,tab2 b,tabl3 c
where a.column1=b.column2
and b.column3 =c.column6
and my_function(parameter)>0
Regards

Edited by: wild fire on May 18, 2012 4:15 PM

Dinesh,
remind that when you use a function in the where clause it normally will get started for each record in the table.
So your answer is two-fold:
1. make the function only start when needed by adding a function based index on the table (this will make inserts and updates slower)
2. make the function faster by adding the DETERMINISTIC clause if possible. this will make Oracle "cache" the result of the function.

Regd. using functions in where clause

Hi All,
I need to apply a set of functions in sysdate and use that in a where clause to compare. My question is, will these functions on sysdate be executed for every record in the tables that I use? Will this have performance impact when i have millions of records returned by the select?
Below is the scenario:
Select * from table A inner join table B on A.c1 = B.c1 where
TO_NUMBER(TO_CHAR(TRUNC(LAST_DAY(ADD_MONTHS(SYSDATE, -1))),'YYYYMMDD')) BETWEEN Date1 and Date2

Test it on a small data set - run a query and check the execution plan to see what the predicate section tells you.
Oracle OUGHT to be smart enough to recognise that you've got a constant that it need only calculate once. If not, then change the usage to read:
(select TO_NUMBER(TO_CHAR(TRUNC(LAST_DAY(ADD_MONTHS(SYSDATE, -1))),'YYYYMMDD')) from dual) BETWEEN Date1 and Date2Note, by the way, that 'constant between col1 and col2' is generally a tough one as far as efficiency is concerned; it translates to:
col1 <= constant
and col2 >= constantIn many cases this means oracle has to access a large volume of data (for one of the predicates) and then filter that data (with the other predicate). A typical damage limitation strategy is to create an index on the two columns, arrangin the column order to minimise the range scan on the first column.
Depending on your data patterns and the nature of the predicate there are alternative optimiisation strategies.

Can you use home share where there are 2 itunes on the same computer but under different user profiles?

TS3989 Can you use the search function in a shared photo stream? How?

Can you use the search function in a shared photo stream? When I try to search in the shared photo stream it goes to search in my photos.

I'm not sure there is a solution to your question, other than to not keep so many photos on your devices. If you delete a photo from photo stream, it will delete it from all your devices. To keep them, first save them to your camera roll (tap Edit, tap the photos, tap Share, tap Save to Camera Roll), then import them to your computer as explained here: http://support.apple.com/kb/HT4083. However, given the number of photos you have, a much more practical solution would be to transfer them to your computer using an app like PhotoSync, which will select them all at once and transfer them over wifi.
I'm not sure why you're seeing such a discrepancy in the amount of space taken up by your photos. It's possible that something is corrupt given the large number of photos on your device.

One thing you can test quickly is to put the function call in it's own select ...from dual.
This might make a difference.
However, only you can check this, I don't have your tables or data.
So, what happens if you use:
    paper_code,
    cand_lang,
(select mark_entry.get_ia_entry_status(:v_year, :v_month, assessment_school, subject_option, lvl, cand_lang, component, paper_code) from dual ) AS mark_status
FROM
    (SELECT DISTINCT ccr.assessment_school, --<< is the DISTINCT really needed?
      ccr.subject,
      ccr.subject_option,
...Also, try to find out the purpose of that above DISTINCT, is it really needed or is there some join missing?
