INSTR function in where clause

Hi,
I need to check whether the portion of passed comma separated value is there in one of table column values, if its present then i need to fetch that record from the same table.
Example
table1
col1 col2
01 john
02 Raj
and i am passing '02,04,06' as a input parameter value and based on this value, i need to check in a table and get some record.
procedure p1 (v_string varchar2)
is
select col1, col2
into a, b
from table1
where instr(v_string,........ -- Here i need apply the logic
end;
output
02 Raj
please help me with this logic
rds,
Naga

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

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.

Can't have aggregate function in WHERE clause clause

Dear all,
I've created object in BO XI 3.1 Designer with following criterias:
http://img4.imageshack.us/img4/833/20111201124314.th.jpg
It is a simple number - 1,2,3,4,5.
Now I need to use this object as a criteria for WHERE function in another object.
http://img607.imageshack.us/img607/1543/20111201124717.th.jpg
I receive an error "Can't have aggregate function in WHERE clause <clause>"
How can I overcome this?
P.S. I'm sorry in advance if such topic already exist - I didn't found one.

Hi,
You will have to use Sub query to achieve this. Give more details on what is available and what you need then i could help you out with the complete solution.

Help:alternate for calling function in where clause

Hi ,
In below query i'm calling function in where clause to avoid COMPLETE status records,due to this query taking 700 secs to return result.If i'm remove below function condition it's returning results with in 5 secs.Can you some one advice to any alternate idea for this?

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?

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.

How can we use DECODE function in where clause.

Hi Guys,
I have to use DECODE function in where clause.
like below
select * from tab1,tab2
where a.tab1 = b.tab2
and decode(code, 'a','approved')
in this manner its not accepting?
Can any one help me on this or any other aproach?
Thanks

I am looking for to decode the actual db value something in different for my report.
like if A then Accepted
elseif R then Rejected
elseif D then Denied
these conditions I have to check in where clause.

what are you trying to do?
may be you are looking for
select * from tab1,tab2
where a.tab1 = b.tab2
and
   (decode(:code, 'A','Accepted') = <table_column>
    or
    decode(:code, 'R','Rejected') = <table_column>
   or
    decode(:code, 'D','Denied') = <table_column>

Function in where clause is executed and returns null instead a valid value

Hi all
i have a strange problem.
There is a access-application where i have a pass-through-sql.
This sql is fetching a foreign exchange rate from a history table which holds this rates for every day and i'm going to fetch the rate for the last day of the last month.
Example of the fraction which does not work and which i executed directly on the DB, Oracle 11.2.0.3.0:
select val
,last_day(add_months((trunc(sysdate)+3),-1)) tag
from k.obj_ts_hist th
where obj_id = 2660
and eff_date = last_day(add_months((trunc(sysdate)+3),-1))
--and      eff_date = '01-mar-2013'
eff_date on table k.obj_ts_hist is defined as date.
The function last_day in the where clause leads to null for both values in the select (val and tag).
If i use eff_date = '01-mar-2013' it's all ok, i get the rigth values.
I tested some combinations of the clause, e.g.
eff_date = to_date(to_char(last_day(add_months((trunc(sysdate)+3),-1)),'YYYYMMDD'),'YYYYMMDD')
or
to_char(eff_date,'YYYYMMDD') = to_char(last_day(add_months((trunc(sysdate)+3),-1)),'YYYYMMDD') , etc., but all of them do not work.
Also i tested the clause with select ... from dual, e.g.
select eff_date from
select last_day(add_months((trunc(sysdate)+3),-1)) eff_date from dual
where eff_date = last_day(add_months((trunc(sysdate)+3),-1))
This work's !
A cross check on Oracle 9.2.0.8.0: it works as expected !
Thanks in advance for your effort.
Regards, Konrad

a little simulation of your formula
select the_date,last_day(add_months((trunc(the_date) + 3),-1)) eff_date

          from dual

Date functions in WHERE clause? HELP

The following two queries are identical except for how I supply the date values in the where clause, yet the first query using the a custom my_date function runs 30x slower than the one using the TO_DATE() function. Both return DATE types...any reason for the difference?
SELECT * from outcomes
WHERE start_time >=fn_my_date('START_MONTH')
AND start_time < fn_my_date('END_MONTH')+1
-- This runs 30x faster--
SELECT * from outcomes
WHERE start_time >=TO_DATE('08/01/2001','MM/DD/YYYY')
AND start_time < TO_DATE('08/31/2001','MM/DD/YYYY')+1
On the flip side, I've also experienced queries running slower using the TO_DATE() function vs the LAST_DAY(sysdate) for equivalenet dates.
null

I haven't seen the message coming up when using LENGTH or SUBSTR, but every time I connect to a database or attempt to change my preferences (including the "NLS Parameters: Comp" preference), this appears.
You are attempting to set the preference you should be to switch this from ANSI to something else, but SQL Developer is ignoring the preference setting (which I think is a bug).
A way to set the NLS_COMP to something else is to use something like "alter session set nls_comp = BINARY;". Note that changing any preference after that appears to overwrite this and you need to do this for each new connection you start.

Error when using record group type as param in a function in where clause

Hi folks.
I have a record type defined in a packages specification. I have to use this record as parameter to call a function. I am able to call the function if as return its value to a string variable. However, the function should be called into a query to compare the returned value and this code is not compiled.
The code is below:
DECLARE
l_line_group_rec INL_CUSTOM_PUB.inl_ship_headers_rec;
l_name VARCHAR2(100);
l_count NUMBER;
BEGIN
l_name := INL_GET_PARTY_SITE_NAME(l_line_group_rec); -- Compiling successfully
SELECT COUNT(1)
INTO l_count
FROM dual
WHERE INL_GET_PARTY_SITE_NAME(l_line_group_rec) = 'Allied Manufacturing'; --- Error when compiling
END;
I got the error: PLS-00306: wrong number or types of arguments in call to 'INL_GET_PARTY_SITE_NAME'
I would like to know if there is any restriction in using record type as parameter in where clauses or if there is another way to do it.
Thanks in advance

Hi.
The definition of INL_GET_PARTY_SITE_NAME:
FUNCTION INL_GET_PARTY_SITE_NAME(p_line_group_rec INL_CUSTOM_PUB.inl_ship_headers_rec) RETURN VARCHAR2 IS
l_party_site_name VARCHAR2(100);
BEGIN
l_party_site_name := 'Allied Manufacturing';
URN l_party_site_name;
END INL_GET_PARTY_SITE_NAME;
Thanks.

940838 wrote:
Output:- ('ACCOUNTING','SALES')Wrong. ('ACCOUNTING','SALES') is a list of two strings 'ACCOUNTING' and 'SALES' while your function returns a single string '(''ACCOUNTING'',''SALES'')'.
IN clause requires a comma-separated list of values while your function, again, returns just one value. So query is comparing 'SALES' whith '(''ACCOUNTING'',''SALES'')', not with ('ACCOUNTING','SALES') and obviously no match. What you are trying to do is called dynamic SQL. There are plenty examples on how to use it. But you don't need it. Use nested table or varray. I'll use Oracle supplied varray type sys.OdciVarchar2List:
select *

Strange errors when using user defined function in where clause

Hello,
I am having trouble with a function that, when used in the where clause of a select will cause an error if the first column selected is of type INTEGER. Not sure whether I am doing something wrong or whether this is a bug.
Here is a very simple test case:
create table test(
col1 integer not null,
col2 varchar(20) ascii default ''
insert into test values(1,'2011-03-15 05:00:00')
insert into test values(2,'2011-03-15 07:00:00')
CREATE FUNCTION BTR_TAG RETURNS VARCHAR AS
VAR ret VARCHAR(20);
SET ret='2011-03-15 06:00:00';
RETURN ret;
Select * from test where col2 >= BTR_TAG()
Select col1,col2 from test where col2 >= BTR_TAG()
=> Error in assignment;-3016 POS(1) Invalid numeric constant
Select '',* from test where col2 >= BTR_TAG()
Select col2,col1 from test where col2 >= BTR_TAG()
=> works as it should
MaxDB V 7.7.07.16 running on Windows Server 2003
I can replicated the test case above with Sql Studio and other ODBC based tools.

Using user defined function in where clause

Hi,
I have defined function to get maximum date before passed date on the table 'A' and I'm using the same function to get details on that date from the same table 'A' in where clause.
for ex:
SELECT x,y,z
FROM A
WHREE a.date = max_date;
But on one database instance it is running fine and on other it is going in a infinite loop.
Pls help me out
Thanks in advance,
Prashant
