Application Express 4.1.1.00.23 ( plus all earlier versions that I've ever used)
When using the wizard to create a Validation of type "PLSQL Function returning Boolean", why is it mandatory to enter a value in the text field "Error Message" on the screen that follows? This message is never used as the message actually displayed comes from a PLSQL return statement.

I have the following query.
sql
Original
- sql Code
SELECT class, COUNT (class)
FROM nv_table
WHERE l_id IN (
SELECT l_id
FROM n_table
WHERE id IN (1234)
GROUP BY class
ORDER BY class
SELECT class, COUNT (class)
FROM nv_table
WHERE l_id IN ( SELECT l_id FROM n_table WHERE id IN (1234)
GROUP BY class
ORDER BY class
It returns two columns: class and the total number of values in that class.
In some cases, there might not be any values under a certain class, so the query won't return anything.
In such a case I want the query to return 0. So what I want to see is:
class:A, COUNT(class):0
I'm trying to use the NVL function here, but either it doesn't work in this context, or it's not the correct syntax the way I'm writing it.

SELECT class, NVL(COUNT (class), 0)

WHERE l_id IN (

When we create sql and some pieces of sql are implemented as oracle function. and we run this sql only once every day. I read article that function after first run located in cache. This part of cache ( with function ), is it really consume one oracle resources? Or it will be erased after while.

I am trying to search a way to get the SQL statement that caused an exception withing an oracle function.
I tried:
SELECT sql_text
from v$session ses, v$sql sql
where sql.sql_id = ses.prev_sql_id
and ses.sid = sys_context('userenv','SID') AND ROWNUM = 1;
but this doesn't always return the last statement that the function has executed. if needed i can send the complete script for the function and its tables and stored procedures for testing.

I am getting a (PL/SQL: ORA-00903: invalid table name) compile error in a procedure using a merge statement. I have seen many examples using this technique and am at a loss as to why I can't compile.
the pipelined function is:
FUNCTION f_crcli_pipe(pi_source_data IN sys_refcursor,
pi_limit_size IN PLS_INTEGER DEFAULT pkg_crcli_variables.c_cursor_limit_def)
RETURN CRCLI_AA
PIPELINED
PARALLEL_ENABLE(PARTITION pi_source_data BY ANY)
IS
[code].....
the error is pointing to the TABLE function in the USING clause of the merge statement.

In the below SQL, I am calling a function "listagg_nm(deptno)", and function is to get all the employee name for a particular department with comma separated
output is:
-------------------------------------------------
DEPTNO SAL LISTAGG_NM(DEPTNO)
10 5000 KING,CLARK,MILLER
10 1300 KING,CLARK,MILLER
10 2450 KING,CLARK,MILLER
20 2975 JONES,SCOTT,FORD,SMITH,ADAMS
[code]....
below are the code
select deptno,sal,listagg_nm(deptno) from emp order by deptno;
FUNCTION listagg_nm (p_deptno NUMBER)
RETURN CLOB
IS
v_str CLOB;
[code]....
My doubt/question is for every row in the SQL the function is being called. t means that for 1st row deptno=10, the function is called and return all concatenated name for department 10, then again for 2nd row deptno=10, it again do the same, similarly for all other department.
Can we avoid this, I mean, if function is already returned a concatenated string of ename for deptno=10, then in the next function call it will checks if it is for same department (i.e. deptno=10) then the function will not go into for loop and it will directly return the concatenated string of ename for deptno=10 which we already done for the first row and so on for other department number ( something like storing the value in variable. Is it possible to achive this and does this is good for performance as we are not going into loop inside the function to return the concatenated string of ename for the same deptno everytime ( I have to return more than 10000 char., so i used clob in function and similarly the numbers of row return by SQL is more than 1000)and also how to code this, I tried but unable to achive.

I have an issue with rather complicated function.Basically it is using DBMS_SQL to execute a very long statement with many parameters (~6000 of them) and binding them with DBMS_SQL.BIND_VARIABLE. Variables are called :1,:2,...,:6000.
When this arguments set is too large - I am receiving error "ORA-00939: too many arguments for function".
Currently I am thinking about dividing the query into subqueries and executing them all with performance decrease.

How to call a function with a row type return in an Oracle select statement.
For e.g. :
If I had this function with a rowtype return:
------------------------------
create function abc
return xyz%rowtype
is
rec xyz%rowtype;
begin
select * into rec from xyz where col1 = n;
return rec;
end;
--------------------------------
How could I use this in a select clause, as there is a multi column return by the function ?

I am using JDBC to run a few queries from my Java program (multi-threaded one).I am facing an issue where a select statement is blocking a delete statement. From the java code point of view, there are 2 different threads accessing the same tables (whith different DB connection objects).
When the block occurs (which i was able to find out from the java thread dump that there is a lock on oracle), the below is the output:
SQL> SELECT TO_CHAR(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 || ' User '||s1.username || '@' || s1.machine
3 || ' ( SID= ' || s1.sid || ' ) with the statement: ' || sqlt2.sql_text
||' is blocking the SQL statement on '|| s2.username || '@'
4 5 || s2.machine || ' ( SID=' || s2.sid || ' ) blocked SQL -> '
6 ||sqlt1.sql_text AS blocking_status FROM v$lock l1, v$session s1, v$lock l2 ,
7 v$session s2,v$sql sqlt1, v$sql sqlt2
8 WHERE s1.sid =l1.sid
9 AND s2.sid =l2.sid AND sqlt1.sql_id= s2.sql_id
AND sqlt2.sql_id= s1.prev_sql_id AND l1.BLOCK =1
10 AND l2.request > 0 AND l1.id1 = l2.id1 AND l2.id2 = l2.id2;
[code]...
From the above it can be seen that a select statement is blocking a delete. Unless the select is select for Update, it should not block other statements is not it ?

substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,
case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2
from table(f_carat_issues_as_of('31/MAR/2013')) i inner join v_gcrs_with_stream gcrs on i.segment_id = gcrs.segment_id
where UPPER(ISSUE_STATUS) like '%OPEN%'
Now I want to callte two columns:ISSUE_DIVISION and ISSUE_DIVISION_2
if they are equal in new columns should be value 1 if are not equal should be 0,how can I do it ?
