Call a function in a where clause of a select

hello,
is it possible to call a function in a where clause of a select????
ex: select col1, col2
from my_table
where my_package.my_function(32199, 2008, col3, 'P');
and i have error message "ORA-00920: invalid relational operator"
FUNCTION my_function(v_matricule IN NUMBER,
          v_Year IN NUMBER,
          v_date IN DATE,
          v_type IN CHAR DEFAULT 'P')
RETURN BOOLEAN;

RETURN BOOLEAN;You can call a function if it returns a datatype that is supported by SQL. BOOLEAN is NOT supported by SQL.

Table function sensitive to where clause?

Hi-
In Oracle SQL, you can use the results of a PL/SQL function as a table with the "TABLE()" syntax. Example: "SELECT * FROM TABLE(myfunction(param1,param2)) ..."
Is there any (non-crazy) way for the function to be aware of the conditions in the WHERE clause of that SELECT statement? For example, if I wanted "myfunction" to know that I had specified "WHERE param3=10' without having to put param3 in the function call, could this be done?
Other SQL implementations support this. I know of at least one where you can map a table on top of a function where the "in" parameters can correspond to columns on the mapped table. Does Oracle support a similar syntax or strategy?

Not sure if it is too crazy for you ;)
But again I rely on a helper function since I am not sure about the purpose of the whole thing:
SQL> create or replace function set_param (p varchar2) return varchar2
as
begin
dbms_application_info.set_client_info(p);
return p;
end set_param;
Function created.
SQL> create or replace function myfunction
   return sys.dbms_debug_vc2coll
as
begin
   return sys.dbms_debug_vc2coll (sys_context ('userenv', 'client_info'));
end myfunction;
Function created.
SQL> select   *
from   table (myfunction())
where   set_param (3) is not null

Function use in where clause

hi,
can we use output of a function in where clause directly ?
i.e
select node(condition1) clause from dual;
clause
occupation='SALARY'
then i want to use this output i.e clause string directly in select stmt.
select * from abc_table where clause
more strictly
select * from abc_table where (select node(condition1) clause from dual)
which is interpreted as
select * from abc_table where occupation='SALARY'
Is there any way to use functions in clause area ???
I tried CURSOR but not workd for this
Thanks in advance,
Rup

SUBSTR function in the where clause

HI
I want to get a number of 15 digits from a column where the user only know the last 10 digits.
So that when the user enter a number with 10 digits, only the record of that specific number should be displayed.
And then when the user did not enter any number all the records in the table should be displayed.(this part works fine)
The problem is: when the user enters any last digits( last, second last, thirth last and so on) the records which satisfy this are retrieved, which is not supose to be the case.
I' am trying to use the substr function in the where clause but I'm not sure if it's working or not becasue the result of the query is just the same as before i used the substr.
Thanks

CBO and functions in the WHERE clause

Hi,
Can anyone point me to any documents describing how the cost based optimizer treats functions in a WHERE clause?
For example, in
select ...
from   ...
where ...
and    my_package.my_function( t.some_column ) = 'Y'
...does the CBO treat "my_package.my_function" as a black box or does it go into the body of "my_package.my_function" and take into consideration the associated costs of all the SELECT statements in the function?
I've tried a few simple tests to answer the question, but I've received conflicting results. Has anyone had any experience with this?
Thanks in advance for your help.

Thanks for the info. Justin.

I think I've solved my problem, but I'll repeat it here in case it helps anyone else. Here is a very simplified example of what I was seeing.
<br><br>
A query like this:
    select
      a.party_id, b.cust_account_id
    from
      hz_parties a,
      hz_cust_accounts b
    where
      a.party_id = b.party_id
      and mis_hz_merge_veto_pkg.party_merge_will_be_vetoed(a.party_id) = 'N'was returning a drastically different execution plan than this
    select
      a.party_id, b.cust_account_id
    from
      hz_parties a,
      hz_cust_accounts b
    where
      a.party_id = b.party_id
      and mis_hz_merge_veto_pkg.account_merge_will_be_vetoed(b.cust_account_id) = 'N'I initially thought the difference was due to the fact that I was using different functions in the last line, but then I tried this version
    select
      a.party_id, b.cust_account_id
    from
      hz_parties a,
      hz_cust_accounts b
    where
      a.party_id = b.party_id
      and mis_hz_merge_veto_pkg.party_merge_will_be_vetoed(b.party_id) = 'N'and found that it gave me a different execution plan than the first SELECT as well, even though it used the same function. The difference seems to stem from the columns I use in the function parameter and not the choice of function.

Values from a Multi-Select in the where clause of a Select statement

I have a web page that solicits query parameters from the user.
The selections that the user makes will populate the WHERE clause of a Select statement.
One of the controls on the page is a multi-select control.
When this page posts, I would like to execute a Select statement wherein the selected values from this control appear in the .. Column IN ( <list here> ) portion of the WHERE clause.
This is an extremely common scenario, but I cannot seem to locate a how-to or message thread that addresses this specific case.
I have an idea that it may involve dynamic SQL or Execute Immediate, but cannot seem to pin down the answer.
Any help would be greatly appreciated!

How to use a function in a Where Clause?

Hi,
I've got a doubt. If MY_FUNCT is a function that returns a boolean, can I use it in a where clause for writing a query like this?:
select ...
from table a
where ...
and MY_FUNC (a.field) = true
Thanks!
Edited by: Mark1970 on 2-lug-2010 3.27

Bear in mind that this could kill your performance.
Depending on what you're doing, how many tables and other predicates are involved, you might want to try to eliminate all other data early before applying your function predicate otherwise your function might be called more times than you might have imagined. Strategies for this include subquery factoring and the old ROWNUM trick for materialising an inline view.
If performance is impacted, you might also want to consider using a function-based index provided that the function is deterministic.

To_Date function in the Where Clause

Hello All,
I'm having an issue using the to_date function that has me quite perplexed.
I have two varchar2 fields, one with a date value in the format Mon, DD YYYY, the other has a time value in the format HH:MI PM.
When I run my query one of the columns I retrieve looks like this TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM'). The two fields are concatenated together and converted to a date. This works fine.
My problem occurs when I attempt to apply the same logic to the where clause of the aforementioned query. e.g. when I add the following criteria to my query and TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM') <= sysdate I get an ORA-01843: not a valid month error.
To further illustrate my problem here are the two queries:
Select d4.adate, e4.atime, TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM')
from ....
where ....
The above query works.
Select d4.adate, e4.atime, TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM')
from ....
where ....
and TO_DATE (d4.adate || e4.atime, 'Mon DD, YYYYHH:MI PM') <= sysdate
The second query does not work.
The tables used and the limiting criteria are identical, except for the last one.
Does anyone have any ideas why this could be happening.

Function/Subrutine and where clause

Hi,
Is it possible to define a subroutine.function and use it in the SQL where clause in ABAP??
If so, any reference code??
Regards,
Kit

Hi Kit,
It is not possible to define a subroutine.function and use it in the SQL where clause in ABAP.
But you can use dynamic where clause. Try F1 on select.
Example
Display of flight connections after input of airline and flight number:
PARAMETERS: carr_id TYPE spfli-carrid,
            conn_id TYPE spfli-connid.
DATA:       where_clause TYPE STRING,
            and(4),
            wa_spfli TYPE spfli.
IF carr_id IS NOT INITIAL.
CONCATENATE 'CARRID = ''' carr_id '''' INTO where_clause.
and = ' AND'.
ENDIF.
IF conn_id IS NOT INITIAL.
CONCATENATE where_clause and ' CONNID = ''' conn_id ''''
    INTO where_clause.
ENDIF.
SELECT * FROM spfli INTO wa_spfli WHERE (where_clause).
WRITE: / wa_spfli-carrid, wa_spfli-connid, wa_spfli-cityfrom,
           wa_spfli-cityto, wa_spfli-deptime.
ENDSELECT.

Using for all entries of two internal tables in where clause of the select

Hi experts,
My requirement is, need to select Marc-minbe and wrpl-sobst, for all the entries of the two internal tables it_mara , and it_t001w.
here is the select queries i have used,
select matnr normt from mara into it_mara for all entries in it_data where normt = it_data-normt.
select konnr werks from t001w into it_t001w for all entries in it_data where konnr = it_data-konnr.
now i need to select minbe of marc table and sobse of wrpl table for all the entries of above internal tables, it_mara and it_t001w, using both matnr of it_mara and werks of it_t001w in where condition.
Pls advise how i can do it.
Thanks.

call SE16 with table TFTIT in order to get a full list (it will be long...)
A list of FMs with parameters can be found in table FUNCT.
Finally go to sm37rsdf4

Using if logic in the where clause of a select statement

I have a select clause. And in the select clause there is a variable all_off_trt that can be 'Y' or 'N'.
In the where clause I want to make it so that if a form variable is checked and all_off_trt is 'Y' then
exclude it else if the form variable isn't checked then select it no matter what all_off_trt is.
Is there any way to include either and if statement or a case statement within the where clause to acheive this? If not is there another way of doing it?
Basically I am looking for a case statement like this
case
when all_off_trt = 'Y' and mail_para.code = 'Y' then false
else true
end

Ok, so that really doesn't solve my problem. I have 3 different fields that I need to do that with. Each combining in a select statement to print an email list, as well as other thing limiting the where clause.
This is currently what I have, tested and working 100%.
cursor email_cur is
select unique p.email,s.all_off_trt,s.all_deceased,s.no_enroll
from participant p, trialcom t, ethics s
where p.status='A'
and p.surname=t.surname
and p.initials=t.initials
and s.trial_cd = t.tricom
and s.centre = t.centre
and p.email is not null
and (t.centre in (select code from mail_parameters where user_name=user and mail_para='CENTRE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='CENTRE'))
and (t.tricom in (select code from mail_parameters where user_name=user and mail_para='TRIAL')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='TRIAL'))
and (t.role in (select code from mail_parameters where user_name=user and mail_para='ROLE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='ROLE'))
and (p.country in (select code from mail_parameters where user_name=user and mail_para='COUNTRY')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='COUNTRY'))
and (t.represent in (select code from mail_parameters where user_name=user and mail_para='REPRESENT')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='REPRESENT'));
This is in a program unit that runs when a button is clicked. At the end of that I need to add on the 3 case statements that help further narrow down the selection of emails to be printed. Then it prints the emails selected from this statement into a file. So it has to be done right in the select statement. The three table variables are the all_off_trt, all_deceased, and no_enroll. The form has 3 checkboxes. One for each, that when checked (giving the variable associated with the checkboxes a value of 'Y') excludes all emails that have a 'Y' in the coresponding table variable.

Re: [iPlanet-JATO] How to make an OR in the WHERE clause of a SELECT

Harry,
If you get a reference to your model, you can set the
whereClauseOverride with exactly the string you want to use. Keep in
mind that you are dealing with a the raw SQL where clause, therefore,
you must use the actual table column names and not the model's logical
field names as they could be different.
QueryModelBase queryModel = (QueryModelBase)getModel(PersonModel.class);
// you must add the "WHERE" as well
String whereClause = "WHERE firstName LIKE '%max' OR lastName LIKE '%max%'";
queryModel.setWhereClauseOverride(whereClause);
Keep in mind that this will override all where criteria: static and
dynamic where criteria. Static criteria can be declared in your model
class: setStaticWhereCriteriaString(STATIC_WHERE_CRITERIA).
You could optionally get the entire SQL statement and replace the
__WHERE__ token yourself with a string replace technique. In fact, if
you want to add an ORDER BY, you will need to get the SQL and append to
the end.
queryModel.getSelectSQL();
Hope this helps. Let me know if you have any questions

        CASE WHEN CPORT.ID = (select REGEXP_SUBSTR(ports_2,'[^,]+',1,1) from p_circuits_fiber)
             THEN "CPORT"."PORT_NO" END PORT_NO_2
from    "CPORT",
        "P_CIRCUITS_FIBER"
where   p_circuits_fiber.fiber_id = :P4000_CIRCUIT_NO
and     (select REGEXP_SUBSTR(ports_1,'[^,]+',1,1) from p_circuits_fiber) = "CPORT"."PORT_NO" "PORT_NO_1"
and     (select REGEXP_SUBSTR(ports_2,'[^,]+',1,1) from p_circuits_fiber) = "CPORT"."PORT_NO" "PORT_NO_2"{code}
Now we can see two columns references which should not be there.
I even not sure to understand why those two conditions are in the WHERE clause. But for sure, CPORT.ID cannot be equal to two values unless they are same.
Is there only one row in p_circuits_fiber ?

How to pass the parameter in the where clause of the select statement

Hi All,
Iam getting one of the value from the Input otd and using this value i need to query one of the tables in oracle database and selected the table using the oracle eway otd like shown below .
otdRISKBLOCK_1.getRISKBLOCK().select() .
where clause in side the select takes a string parameter as Iam getting the string parameter from the input otd and passing this to where clause by creating a string literal after deployment it is giving an error saying "ORA-00920: invalid relational operator".
can any one throw some input on this .
Thanks in Advance

You will see this error if the search condition was entered with an invalid or missing relational operator.
You need to include a valid relational operator such as
=, !=, ^=, <>, >, <, >=, <=, ALL, ANY, [NOT] BETWEEN, EXISTS, [NOT] IN, IS [NOT] NULL, or [NOT] LIKE in the condition. in the sql statement.
Can you throw some more light on how are you designing your project?

Where clause priority in Select Query

Hi All,
I have one doubt, Pls clarify
SELECT empno, ename, sal, comm
FROM emp E, dept D -- (deptno is pk for DEPT)
WHERE D.deptno = E.deptno
AND E.sal >= 3000
In WHERE clause which one will execute first (right to left or left to right
OR[b] First join conditions then after filter conditions or vice versa)
D.deptno = E.deptno
OR
E.sal >= 3000
(this is the example tables)
Because I have large volume of data with 5 tables with joins
so, pls. kindly give me the sugession for where clause.
Thanks
Naresh

It depends, the order the where clause is written in makes no difference to how the statement is processed.
In the section on Developing Efficient SQL Statements in the Performance Tuning Guide changing the order of statements in the where clause is notably missing.
There is more information in the Understanding Joins section of the same manual.
