Limitations in using a function within a select statement

I have a function which retrieves various data elements from the
database and formats it accordingly. The data (varchar2)
returned could be in excess of 2,000 characters length.
I need to use the returned data as part of a view. I am able to
use the function in a "select" statement, but when I use it with
returned data in excess of 2,000 chars, I get the following
error:
ORA-06502: PL/SQL: numeric or value error
This error is occurring whenever the returned data is in excess
of 2,000 characters.
Is there an alternative method to what I am proposing, I have
tried alternative data types but if I am able to use it in a
"select" statement, I get the above error when the returned
length exceeds 2,000 chars.
Thanks
Peter

are u using oracle 7. varchar2 limit in 8 is 4000.

DBMS_XMLQuery behavior when using stored function within cursor select

Consider the following SQL Statement
select t1.id
, t1.name
, cursor ( select t2.id
from tab t2
where t2.t1_id
= t1.id
and validate(t2.xyz,:bd1)
= 1
from tab t1
where t1.id = :bd2
DBMS_XMLQuery is used to create a context and to bind the appropriate values. In this case 'validate' is a stored function. I get the following error message upon execution:
ORA-29532: Java call terminated by uncaught Java exception:
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
Issuing a similar statement in SQL*Plus works fine. I was wondering whether this is a known issue when using a stored function in the cursor select statement in the context of DBMS_XMLQuery or whether I'm doing something wrong.

Hi Jan,
This problem has been identified and fixed. The fix should be available in the next release. Thank you for bringing this up to our attention.

Using Saxon Functions Within XSLT

Hi,
Please let me know how to use saxon functions within XSLT.
E.g.: If I want to implement saxon:base64Binary-to-string() function in XSLT in "xsl:value-of" function, then what will be the format for implementation.
I have selected the Processor as Saxon 8.9.0.3 (the one available) and using xmlns:saxon="http://saxon.sf.net/" in the xsl:stylesheet tag.
I am using Stylus Studio 2007 XML Enterprise Suite for XSLT.
Thanks,
Abhishek.

Hi,
Yes I intended to use the XLST mapping within PI...but now will have to change the plan...is there any other way to do it?....is this the problem with the SP?.....anybody who can put more light on this topic.....
Thanks,
Abhishek.

Can call a function in the select statement?

Is there any ways to call a function in the select statement?
what I like to do is this:
select deptno, totalEmployees(deptno), TotalSalary(deptno)
from emp;
I know it can be done by count(*) and join tables, but my case
is much more complex and the where clauses are different from
one function to another, and have many tables to join and many
combinations
Thanks

Functions can be used in a select statement subject to certain
restrictions, see
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/
server.817/a85397/statem9b.htm#2062024
It's under "CREATE FUNCTION> Keywords and Parameters> function>
Restrictions on User-Defined Functions"
Here is an except...
When a function is called from within a query or DML statement,
the function cannot:
a) Have OUT or IN OUT parameters
b) Commit or roll back the current transaction, create or roll
back to a savepoint, or alter the session or the system. DDL
statements implicitly commit the current transaction, so a user-
defined function cannot execute any DDL statements.
c) Write to the database, if the function is being called from a
SELECT statement. However, a function called from a subquery in
a DML statement can write to the database.
d) Write to the same table that is being modified by the
statement from which the function is called, if the function is
called from a DML statement.
Except for the restriction on OUT and IN OUT parameters, Oracle
enforces these restrictions not only for the function called
directly from the SQL statement, but also for any functions that
function calls, and on any functions called from the SQL
statements executed by that function or any function it calls.

Will a explain plan consider a function in a select statement.

Hi gurus,
I have a question regarding explain plan.
I ran a query, which returns me explain plan with multiple CPU costs around 300K.
now i use a function, and the number of lines displayed in explain plan reduces from 12 to 8 lines.
What i dont understand is.. Is the explain plan considering the function in the select statement ?
ex.
explain plan for
select column1,
         column2,
         function(value1)
from case
where case_no = 1will a explain plan consider the functions in a select statement ?
Thank you.

What i dont understand is.. Is the explain plan considering the function in the select statement ?Maybe there are tweaks which reveal more information from the explain plan, but a straightforward way won't necessarily expose any function call:

Using pop-up value in select statement

Hello.
I want to select a value from a pop-up box and then use that value in a select statement for another pop-up. Is that possible?
The first pop-up is P39_PIIN_CALL but it is not recognized in the second pop-up when I use it in the select statemnt... select * from table where PIIN = :P39_PIIN_CALL. I get nothing back because it has no idea what :P39_PIIN_CALL is. I'm desperate and on a timeline.
Thanks,
Mark E

Hi,
After fetching the value from first popup the page should submit so that the value is availble to the second popup..
Edit the first popup.. and in HTML Form Element Attributes and enter onchange="doSubmit('MyRequest')"

Use of cursors insted of select statements

could any one please explain what is the advantage of using cursors instead of simple select statements
thanks
siby

A benefit to using an explicit cursor rather than a select statement, is for the NO_DATA_FOUND exception. Its kind of like a free IF statment. IF no data is found, then stop.
if you write a select statement, and no data is returned, you SHOULD code for the NO_DATA_FOUND exception. Often people say, "i'll ALWAYS get a row returned". but you should always cover your code "just in case". so you must code an exception...
declare
v_var varchar2(1);
procedure do_something(p_parm varchar2) is
begin
null;
end do_something;
procedure log_error is
begin
null;
end log_error;
begin <<main>>
do_something('x');
begin <<selectblock>>
select dummy
into v_var
from dual
where dummy = 'a';
do_something(v_var);
exception
when no_data_found then
log_error;
end selectblock;
do_something (v_var||'abc');
end main;
if you use an explicit cursor instead, you don't need to code for the NO_DATA_FOUND. If an explicit cursor opens and finds no rows, there are simply no rows. of course, you don't need a loop if you expect only 1 row returned under normal circumstances.
BTW, don' forget that SQL%ROWCOUNT and your_cursor%ROWCOUNT are not initialized. There is a null, until a row is successfully fetched. therefore if no rows are returned at all, %ROWCOUNT is NULL.
declare
v_var varchar2(1);
cursor my_cur is
select dummy
from dual
where dummy = 'a';
procedure do_something(p_parm varchar2) is
begin
null;
end do_something;
procedure log_error is
begin
null;
end log_error;
begin << main>>
for cur_rec in my_cur loop
dbms_output.put_line('inside');
begin <<loop_block>>
if nvl(my_cur%rowcount,0) > 1 then
do_something(cur_rec.dummy);
else
log_error;
end if;
end loop_block;
end loop;

Using a function within a process flow...

Hi,
I'm trying to figure out a way of using a function (or something else) to return a status before attempting to run a mapping. I'd like to have a table with all my mappings, start date, end date, status, etc.
1. SELECT status FROM table, if the mapping has already been executed do nothing, else execute the mapping, etc.
Is there a way to accomplish that in OWB flow ?
Thank you.
GaÃ©tan

Hi,
We had a similiar set up in my previous role where we have a Process flow for each mapping. Under that processflow, before attempting to run the mapping we called function to check whether that particular mapping has been run successfully for that date. The function would take "PF Name" as an input and returns the status as 1 (return success - the mapping was not run, so has to be run today)
2 (return warning - the mapping is already run no need to run this time)
3 ( any fatal errors).
The function code is as below - _______________________________________________________
CREATE OR REPLACE FUNCTION "PUB_CHECK_RUN_STATUS"("IN_ETL_PROCESS_FLOW_NAME" IN VARCHAR2) RETURN NUMBER IS
--initialize variables here
lv_Current_Load_Id NUMBER;
lv_Last_Load_Id NUMBER;
BEGIN
     <<Check_PF_Status>>                    -- This block is Standard for all Loads Jobs
     BEGIN
          SELECT LOAD_ID
          INTO lv_Current_Load_Id
          FROM LOAD_ADMIN.LATEST_LOAD;
          SELECT LAST_COMPLETE_LOAD_ID
          INTO lv_Last_Load_Id
          FROM LOAD_ADMIN.ETL_PROCESS_FLOW
          WHERE ETL_PROCESS_FLOW_NAME = in_ETL_Process_Flow_Name;
          IF Lv_Last_Load_Id = lv_Current_Load_Id
          THEN
               -- This Process Flow has already been completed during this Load, so do not re-run
               RETURN 2;          -- Returns a Warning Status
          ELSE
               -- This Process Flow has not completed during this load, so need to run this now
               RETURN 1;          -- Returns a Success Status
          END IF;
     END Check_PF_Status;
EXCEPTION
WHEN OTHERS THEN
RETURN 3;     -- Returns an Error Status
RETURN NULL;
END;
In the above code
LATEST_LOAD is a view which always returns one row with current load information (like load _id, start time etc)
ETL_PROCESS_FLOW is a table containing one row for each process flow with information like (execution status, load_id when it was execute )
You can modify to suit your requirements.

Why a function within a SELECT FROM DUAL is faster?

1)I have a SELECT with a function. Ex:
"SELECT DISTINCT function(...) FROM table"
2)I changed the SELECT and put the function inside a SUB-SELECT with FROM DUAL. Ex:
"SELECT DISTINCT (SELECT function(...) FROM DUAL) FROM table"
3)The second SELECT is faster than the first.
I discovered this problem on my tables and my functions. So I did a generic example for this forum with a common function and large table. My results:
Table has 2.196.058 records and the field is a VARCHAR2:
SELECT DISTINCT SUBSTR(field, 2) FROM Table -> Executed in 110 seconds
SELECT DISTINCT (SELECT SUBSTR(field, 2) FROM DUAL) FROM Table -> Executed in 39 seconds
Why "SELECT DISTINCT (SELECT function(...) FROM DUAL) FROM table" is faster than "SELECT DISTINCT function(...) FROM table"
thanks,
Fernando

Hi hoek,
I followed your informations and, sorry, I am more confused! I did an interesting example below.
1)I created a table:
CREATE TABLE T
     name VARCHAR2(50)
);     2)I inserted 10 lines:
NAME
A
B
C
D
E
F
G
H
I
J                                                  3)I created a function that returns the parameter concatenated with the current millisecond:
CREATE OR REPLACE FUNCTION f (param1 IN VARCHAR2) RETURN VARCHAR IS
BEGIN
     return param1 || '-' || to_char(CURRENT_TIMESTAMP, 'FF');
END;     4)The query(A): SELECT f(name) AS col1, f(name) AS col2, f(name) AS col3 FROM t; gave me:
COL1        COL2        COL3

J-694638000 J-694664000 J-694690000If I repeat the SELECT, new values are generated.
4)The query(B): SELECT (SELECT f(name) FROM Dual) AS col1, (SELECT f(name) FROM Dual) AS col2, (SELECT f(name) FROM Dual) AS col3 FROM t; gave me:
COL1        COL2        COL3

J-254495000 J-254523000 J-254551000The result generated new values too.
5)I changed the function and I put the DETERMINISTIC clause:
CREATE OR REPLACE FUNCTION f (param1 IN VARCHAR2) RETURN VARCHAR DETERMINISTIC IS
BEGIN
     return param1 || '-' || to_char(CURRENT_TIMESTAMP, 'FF');
END;     6)I repeated the queries(A) and (B) and the result has generated different values. Then, with the DETERMINISTIC clause, the result has not changed
7)I changed the function and I put the RESULT_CACHE clause:
CREATE OR REPLACE FUNCTION f (param1 IN VARCHAR2) RETURN VARCHAR RESULT_CACHE IS
BEGIN
     return param1 || '-' || to_char(CURRENT_TIMESTAMP, 'FF');
END;8)I repeated the query(A) and now, the result was different:
COL1        COL2        COL3
A-381048000 A-381048000 A-381048000
B-381242000 B-381242000 B-381242000

J-381971000 J-381971000 J-381971000The line columns are equals and if I repeat the SELECT, all the result is the same too. The query(B) returned the same result like the query(A)! Now I see the cache in action!
After the tests, I concluded that the function in the subquery doesn't use cache and it is faster than the normal function. The mistery continues...

Trouble using pipelined function in an select list lov query

I'm trying to use a pipelined function in a select list lov query but i cet the error
"LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query."
my query is as follows :
SELECT gt.navn d, gt.GEOGRAPHY_TYPE_ID r
FROM GEOGRAPHY_TYPE gt
WHERE gt.kode NOT IN (1)
and gt.kode in (select lov_value from table(RAPPORT_FILTER_PKG.GET_RAPPORT_FILTER_VALUE_PIP (
SYS_CONTEXT ('rapport_filter_ctx','filter_id'),'GEOGRAPHY_TYPES')) )
ORDER BY gt.navn DESC
if i use a discrete values '80' instead of the call to
SYS_CONTEXT ('rapport_filter_ctx','filter_id')
i don't get eny errors, but then the LOV isn't as dynamic as i has to be
any idears???

Edited by: [email protected] on Dec 1, 2008 11:17 AM

nope that doesn't do it either
contains a syntax errror at
SYS_CONTEXT (('rapport_filter_ctx',:P500_RAPPORT_FILTER_ID),'GEOGRAPHY_TYPES'))
my theory is that it's got something to do with the way APEX binds values because
the query
SELECT gt.navn d, gt.GEOGRAPHY_TYPE_ID r
FROM GEOGRAPHY_TYPE gt
WHERE gt.kode NOT IN (1)
and gt.kode in (select r from table(RAPPORT_FILTER_PKG.GET_RAPPORT_FILTER_VALUE_PIP ('80','GEOGRAPHY_TYPES')) )
ORDER BY gt.navn DESC
works fine in both TOAD and in APEX but as soon as i replace th '80' with :P500_RAPPORT_FILTER_ID then, apex won't accept the code??????

Return multiple values from a function to a SELECT statement

I hope I've provided enough information here. If not, just let me know what I'm missing.
I am creating a view that will combine information from a few tables. Most of it is fairly straightforward, but there are a couple of columns in the view that I need to get by running a function within a package. Even this is fairly straightforward (I have a function named action_date in a package called rp, for instance, which I can use to return the date I need via SELECT rp.action_date(sequence_number).
Here's the issue: I actually need to return several bits of information from the same record (not just action_date, but also action_office, action_value, etc.) - a join of the tables won't work here as I'll explain below. I can, of course, run a separate function for each statement but that is obviously inefficient. Within the confines of the view select statement however, I'm not sure how to return each of the values I need.
For instance, right now, I have:
Table1:
sequence_number NUMBER(10),
name VARCHAR(30),
Table2:
Table1_seq NUMBER(10),
action_seq NUMBER(10),
action_date DATE,
action_office VARCHAR(3),
action_value VARCHAR(60),
I can't simply join Table1 and Table2 because I have to do some processing in order to determine which of the matching returned rows I actually need to select. So the package opens a cursor and processes each row until it finds the one that I need.
The following works but is inefficient since all of the calls to the package will return columns from the same record. I just don't know how to return all the values I need into the SELECT statement.
CREATE VIEW all_this_stuff AS
SELECT sequence_number, name,
rp.action_date(sequence_number) action_date,
rp.action_office(sequence_number) action_office,
rp.action_value(sequence_number) action_value
FROM table1
Is there a way to return multiple values into my SELECT statement or am I going about this all wrong?
Any suggestions?
Thanks so much!

Hi,
What you want is a Top-N Query , which you can do using the analytic ROW_NUMBER function in a sub-query, like this:
WITH     got_rnum     AS
     SELECT     action_seq, action_dt, action_office, action_type, action_value
     ,     ROW_NUMBER () OVER ( ORDER BY action_date
                               ,            action_seq
                         ,            action_serial
                       ) AS rnum
     FROM     table2
     WHERE     action_code     = 'AB'
     AND     action_office     LIKE 'E'     -- Is this right?
SELECT     action_seq, action_dt, action_office, action_type, action_value
FROM     got_rnum
WHERE     rnum     = 1
;As written, this will return (at most) one row.
I suspect you'll really want to get one row for each group , where a group is defined by some value in a table to which you're joining.
In that case, add a PARTITION BY clause to the ROW_NUMBER function.
If you'd post a little sample data (CREATE TABLE and INSERT statements), I could show you exactly how.
Since I don't have your tables, I'll show you using tables in the scott schema.
Here's a view that has data from the scott.dept table and also from scott.emp, but only for the most senior employee in each department (that is, the employee with the earliest hiredate). If there happens to be a tie for the earliest hiredate, then the contender with the lowest empno is chosen.
CREATE OR REPLACE VIEW     senior_emp
AS
WITH     got_rnum     AS
     SELECT     d.deptno
     ,     d.dname
     ,     e.empno
     ,     e.ename
     ,     e.hiredate

                         ,                e.empno
                       ) AS rnum
     FROM     scott.dept     d
     JOIN     scott.emp     e     ON     d.deptno     = e.deptno
SELECT     deptno
,     dname
,     empno
,     ename
,     hiredate
FROM     got_rnum
WHERE     rnum     = 1
SELECT     *

By the way, one of the conditions in the query you posted was
action_office     LIKE 'E'which is equivalent to
action_office     = 'E'(LIKE is always equivalent to = if the string after LIKE doesn't contain any wildcards.)
Did you mean to say that, or did you mean something like this:
action_office     LIKE 'E%'instead?

How to pass an array to a function from a SELECT statement

Hi all. I have a problem with passing an array to a function directly from a SELECT statement.
Here is what I want. If I have a function
function AAA(arrayVar <ArrayType>) return number;
I want to be able to call this function this way
select AAA((2,3,4))
from dual
or this way
select AAA((10,12))
from dual
In other words I want to be able to pass an arbitrary number of numbers to the function. And I want this to work in a SELECT statement.
Does anyone have any ideas how to implement this? What <ArrayType> should I use?(I've read about VARRAY, nested tables in the Oracle documentation but as far as I've understood these array types are meant to be used within PL/SQL blocks).
I found only this http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:208012348074 through Google but it didn't help me.
Thank you in advance.

> What <ArrayType> should I use?
SQL data types - as 3360 showed above. You cannot use PL/SQL structures and user types in the SQL Engine.
You can however use all SQL structures and types in PL/SQL.
Arrays in SQL is created as collection type - basic o-o. The collection type (or class) serve as a container for instantiated objects or scalar type.

Calling a user defined function in a select statement

PLS-00231: function 'F_GET_PROJECT_ID' may not be used in SQL
I am caling a user defined function 'F_GET_PROJECT_ID' in a select statement and getting the above error .
Can any one help me to resolve it.
I can not replace the function with a local variable nor can I assign the output of the function to a variable and use the variable in the sql stmt. cos, the in put parameters of the function comes from the same select statement.
Please help
Thanks in advance

Can you provide your function code? Using a function like that is possible from the below example. I suspect something in your function code.
SQL> create or replace function sample_func(p_sal number)
2 return number
3 is
4 v_sal number;
5 begin
6     v_sal := p_sal+100;
7     return v_sal;
8 end;
9 /
Function created.

I think that the problem is that the function apex_util.prepare_url is executed building the "q" variable, not during query execution. (you have to try to quote it ...)
I often use the "Query from function".
There a couple of things that helps me:
- I always put in the page an item PXX_SHOW_SQL(checkbox) visible only to administrator (a user setting in my application...).
Before the "return q" put a htp.p(q) if this Item is not null. So you can see the actual SQL (often helps reformattig the output with SqlDeveloper)
- I'm became crasy tring to quote complex query ... Now I write the query code in a TABLE
Example AUXSQL(APP_ID number,APP_PAGE number, PRG number, sql VARCHAR2(4000))
More "PRG" if more than 4000 chars. (I start in this way, but someone use CBLOB ...)
I find this very usefully!!
Thanks
