SQL Statement / index on function ??

Hello
My environment is : Oracle 9.2.0.7
In "top sql sessions" I obtained that sql statement as below consumes many ressources.
When I use "SQL Analyzer" ... no recommandation was specified but I wonder if an index on function may be use to optimize this request.
I'd like to have your opinion on how to optimize this kind of request :
SELECT trim(CARD_NUMBER) as CARD_NUMBER,
trim(CUSTOMER.CLIENTS.CUSTOMER_ID) as CUSTOMER_ID,
trim(LASTNAME) as LASTNAME,
trim(FIRSTNAME) as FIRSTNAME,
trim(EMAIL) as EMAIL,
FROM CUSTOMER.CARTES, CUSTOMER.CLIENTS
WHERE CUSTOMER.CARTES.CUSTOMER_ID = CUSTOMER.CLIENTS.CUSTOMER_ID
AND trim(CUSTOMER.CARTES.CARD_NUMBER) = '1234567890'
AND (trim(CUSTOMER.CLIENTS.POST_CODE)='12345')
Plan execution is :
SQL STATEMENT :
JOIN
TABLE ACCESS (FULL) CUSTOMER.CARTES
TABLE ACCESS (FULL) CUSTOMER.CLIENTS
Many thanks for any help.
Regards,
Guillaume

AND trim(CUSTOMER.CARTES.CARD_NUMBER) =
'1234567890'
AND (trim(CUSTOMER.CLIENTS.POST_CODE)='12345')Yea function based index on trim(CUSTOMER.CARTES.CARD_NUMBER) and trim(CUSTOMER.CLIENTS.POST_CODE) might help.
BUT I suggest to correct data insertion app and insert already trimmed data in your table to avoid such ugly queries.

How should I pass complicated sql statements to a function ?

Hello
Some built-in functions, such as dbms_advisor.quicktune accepts sql statements as in parameters. Those parameters are treated as varchar2, but if the sql statement is complicated and contain " ' " characters then its hard to pass those params, Sometimes they arent parsed correctly.
How should I pass a complicated statement (with subqueries, strings and so) to a function ?
Thanks

As you can see on 23 they invlalidated the areacode and phone no and changed it to .. 578 658-8521 but on 04-28 they just changed the phone no and not the area code..
I want the result set to be like this

when tt.rank1 <> 1 then Isnull(tt.phoneareacode,tt_prev.phoneareacode)+'-'+ isnull(tt.phoneno,tt_prev.phoneno)
end as FromAddress,
case when tt.rank1 = 1 then Haddress.phoneareacode+'-'+HAddress.phoneno
when tt.rank1 <> 1 then Isnull(tt_prev.phoneareacode,tt.phoneareacode)+'-'+isnull(tt_prev.phoneno,tt.phoneno)
end as ToPhone
from

left join #Phone_Final tt_prev on tt_prev.objectid = tt.objectid and tt.rank1-11 = tt_prev.rank1
inner join (select * from Soarian_Clin_Prd_1.dbo.Haddress where PP_id = 2346   and Addresstype = 0) Haddress
Can you please tell me what is wrong here..

should be this I reckon
;With CTE
AS
SELECT ROW_NUMBER() OVER (PARTITION BY ObjectID ORDER BY InvalidatedTime) AS Seq, *
FROM
SELECT ObjectID,InvalidatedTime,PhoneArea,Phoneno,Rank
FROM LogTable
UNION ALL
SELECT ObjectID, GETDATE(),PhoneArea,Phoneno,NULL
FROM Current
)t
SELECT c1.InvalidatedDate AS [Date],
COALESCE(c1.PhoneArea,c2.PhoneArea,'') + c1.Phoneno AS FromValue,
COALESCE(c2.PhoneArea,c1.PhoneArea,'') + c2.Phoneno AS ToValue
FROM CTE c1
INNER JOIN CTE c2
ON c2.Objectid = c1.Objectid
AND c2.Seq = c1.Seq + 1

SQLEXEC not able to filter extract on sql statement or function call.

hi all,
i'm trying to do some basic extract filtering using a stored function and am not having much success.
i started off using a procedure call but have been unsuccessful getting that working, i've simplified
it to use a sql statement calling a function for a value to filter on, but cannot even get that to work.
i've read through the documentation and i cannot figure out what is going wrong.
any help would be much appreciated.
thx,
daniel

Expensive SQL statements & no proper indexing INCLUDE LPSSTU03-PSST FuncGrp

Hi there forum
During a recent upgrade we have implemented EhP4 with relevant Support Packs.
Our Early Watch Report nows highlights INCLUDE LPSSTU03 in Function Module Group PSST as having expensive SQL statements along with improper indexing.
Although I have seached through OSS and Forums I can find nothing of help.
Is there an EXPERT out there who can help because SAP tells me that is the way it works!
Thanks.

SQL Expression in decode function or case statement?

Can I put SQL expressions in decode function or case statement?
For example,
select le.profile, decode( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile, 0, 'N', 'Y')
from element le;
or
select le.profile, case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0 THEN 'N'
ELSE 'Y'
from element le;
None of the above work.
Can anyone tell me how to make it work?
Is there any workaround?
Thanks,
J

You simply needed and END to your CASE statement;
SQL> with profile_data as (
   select 'XXXX_AFTER' name, 1 object_id from dual),
     element as (
   select 1 profile from dual union all
   select 2 from dual)
select le.profile,
   case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0
   THEN 'N'
   ELSE 'Y'
   END new_col
from element le
   PROFILE N
         1 Y
         2 N

Which is better - SQL Statement in APEX or as a function returning a type?

Hi
I have a general question about best practices for APEX development.
If we have say a report region based on a SQL statement, is it better (from a performance perspective) to have the SQL statement defined in the region in APEX OR have the actual select statement executed in the backend and have the result set returned in a type to APEX?
As an example:
In APEX region
SELECT col1, col2, col3 FROM table_aOR
In APEX region
select col1, col2, col3 from TABLE(CAST(<my package>.<my proceduere > AS <my type >)) ;<my package>.<my proceduere > would obviously execute the statement
SELECT col1, col2, col3 FROM table_ausing dynamic SQL and return the results to APEX in thy type <my type>.
Apologies if this sounds to be a really stupid thing to ask.
Kind regards
Paul

------------------------------------------------------------------------------thanks Denes... but does it matter if:
1. The SQL statement is actually defined in the APEX region
or
2: The select statement is stored in a packageD function and returned to APEX?
I seem to recall an article I read stating that it is best for all client applications to call stored procedures and functions rather than have SQL statement embedded in the actual application?

Marius
Looking at the logic you are trying to create it looks like you are looking for overlapping time periods.
Consider two date/time ranges:
Range 1 : T1 - T2
Range 2 : T3 - T4
Do they overlap?
1) No: T1 < T4 (TRUE) T2 > T3 (FALSE)
T1 --- T2
           T3 --- T4
2) Yes: T1 < T4 (TRUE) T2 > T3 (TRUE)
T1 ---------- T2
           T3 --- T4
3) Yes: T1 < T4 (TRUE) T2 > T3 (TRUE)
T1 -------------------- T2
           T3 --- T4
4) Yes: T1 < T4 (TRUE) T2 > T3 (TRUE)
               T1 ----- T2
           T3 --- T4
5) Yes: T1 < T4 (TRUE) T2 > T3 (TRUE)
           T1 --- T2
       T3 ------------ T4
5) No: T1 < T4 (FALSE) T2 > T3 (TRUE)
                T1 --- T2
       T3 --- T4Answer: Yes they overlap if:
T1 < T4 AND T2 > T3
So you can code the logic in your SQL as simply:
SELECT *
FROM tbl
WHERE range1_start < range2_end
AND    range_1_end > range2_startIf you go around implementing PL/SQL functions for simple logic that can be achieved in SQL alone then you cause context switching between the SQL and PL/SQL engines which degrades performance. Wherever possible stick to just SQL and only use PL/SQL if absolutely necessary.

Calling a PL/SQL function in the SQL statement

I have a PL/SQL function which i should call in a SQL statement.
Let's say the function is func1(parameter1,parameter2),
it should be called like this :- SELECT func1() FROM mytable ;
Can any one help me out on this ?
---Thanx in advance

you can call pl/sql functions from pl/sql using
select fn1('param1','param2') from table;
if you dont want to pass paramters, you have to specify default
value while creating function like below
create function fn1(p1 number default null,p2 varchar2 default
null) return...
now you can call using
select fn1 from table;

Using sql function in xml sql statement

Hello,
I have following statement:
select field1, field2,....,field10 from table( cast (get_mhdata(:1,:2) as mhdata))
where mhdata is an oracle type with 10 fields.
It works good, but I don't know how can I use this statement in xml sql statement.
Please, can you tell me if it is really possible.
Thanks in regards.

Hi
You cant pass the parameters if you are executing writing this select function from the communication channel.
You have 3 options:
1) Use a stored procedure and execute from the communication channel
2) Use a stored procedure and execute via message mapping in the IR - here you can pass parameters
3) Same as above but call the query via SQL select - you can also pass parameters.

My sql client version is 9.2.0.1.0. and my data base version is 10.2.0.2.0.
Please advice.

Could you post the exception handler within the function.
It sounds like you return -1 if you experience an error - it would be easier to determine the cause of the problem if you return the Oracle error details, E.g:
EXCEPTION
WHEN OTHERS THEN
RETURN dbms_utility.format_error_backtrace;This will then return a meaningful error, identifying exactly what is causing the error to be generated.

I am cretaing a function in which I have to extract some fields from three tables and to handle three tables I am first extracting the primary key from one table(acting as a foreign key for other table) in a variable declared in declare section, then I am selecting the required fields from the other table by giving that variable name in Where condition. My code is attached as well.
e.g
Create or Replace function <function name>(arguments)
Return return type
AS
a1 a%TYPE;
b_new b%TYPE;
n fn%TYPE
Select a into a1 from table1 where b like b_new;
Select fn into n from table2 where id like a1;
return a1,n; (can we pass record like this?)
end;

Left's first look at the approach you use.. 2 SQL statements that can be done using a single SQL statement.
Actually it is not as bad as some other code posted here where people go and write complex PL/SQL code to do what could have been done using a single SQL statement.
There are a couple of golden rules in Oracle development. One of these is to 'Maximise SQL and Minimise PL/SQL'.
Why take a value from one SQL statement into PL/SQL and then use that value in a second SQL statement?
Rather do this:
select
fn into n
from table2
where id like (Select a from table1 where b like b_new);Also keep in mind that in PL/SQL the above SQL construct is only able to fetch a single row - look at the bold above. The variable N can only hold a single value. If that SQL SELECT returns more than one value, how is variable N suppose to hold it?
I suggest that you read [url http://www.oracle.com/pls/db102/to_toc?pathname=appdev.102%2Fb14261%2Ftoc.htm&remark=portal+%28Books%29]Oracle® Database PL/SQL User's Guide and Reference guide.
