I have 2 tables, ASSIGNMENT and RESEARCH_PAPER. For each research paper, I need to find out :
1. The number of assignments created from it (after a given constant assign date)
2. The number of assignments created from it that have been approved.
3. The number of unique users who have either created or approved an assignment from it
Test data :
create table research_paper (id int, name varchar2(100));
create table assignment (id int, r_paper_id int, assigner_id int, assignee_id int,
approver_id int, assign_date timestamp, approved_yn varchar2(10));
insert into research_paper values (1, 'A');
insert into research_paper values (2, 'B');
[code]....
Assignment :
id r_paper_id assigner_id assignee_id approver_id assign_date approved_yn
-----------------------------------------------------------------------------------------------------------
11 100 200 100 23-10-12 12:00:00.000000000 AMY
22 200 100 200 22-10-12 12:00:00.000000000 AMN
32 100 200 101 24-10-12 12:00:00.000000000 AMY
[code]....
Research_paper:
id name
----------
1A
2B
Expected result :
r_paper_id created approved unique_users
-----------------------------------------------
1 3 2 4
2 3 2 3
I wrote the following query for that :
SELECT rp.id r_paper_id,
COUNT(*) created,
COUNT(
CASE
WHEN a.approved_yn = 'Y'
[code]....
But it fails, saying that 'single-row subquery returns more than one row' when I introduce the 'unique_users' clause. The remaining fields of the output are correct.

Calling function
select PACK.MAIN('blah') from dual
generates:
ORA-14551: cannot perform a DML operation inside a query
ORA-06512: at "SYSADM.NEW_QUANTUM_PACK", line 756
ORA-06512: at "SYSADM.NEW_QUANTUM_PACK", line 245
Unfortunately the Body is not accessible to see.The spec of the function is:
FUNCTION MAIN (mvar IN varchar2) RETURN varchar2; I read somewhere that I can call it like:
var myVar VARCHAR2; call PACK.MAIN('blah') into :myVar
But this generates: ORA-01008: not all variables bound

I have a cursor returning some value.
for each value returned by the cursor i need to traverse through 31 rows(1 row per day * no of days in the month).
E.g. if cursor returns service_name as xyz then for xyz there can be 31 rows(service may not be used on some days)
I need to go to all of them and take some values and move them to a flat file. how should that be done?

im calling an api inside a cursor.. for the first loop in a cursor , the api works well. however, for the rest of the loops the api doesn't give any error, but it doesn't insert any row to the table.
if i called the same api for every single value in a cursor seperately the api would insert all rows.

I can't understand the following cursor declaration (inside the DECLARE of a PL/SQL block)
CURSOR c_emps IS
SELECT emp_large_ot(empno, ename, job, mgr,hiredate, sal, comm, deptno) FROM emp_large;
emp_large_ot is an object type created as
CREATE TYPE emp_large_ot AS OBJECT
( empno NUMBER
, ename VARCHAR2(10)
, job VARCHAR2(9)
[code]...
and emp_large is similar to the standard emp table

I have a DML Statement inside a procedure and i use a cursor variable to get the values checked as below . I have attached my procedure not completely but the declaration part and the DML statement part.
The issue is my procedure is not inserting the records at all. It selects the values and then inserts accoringly but its not selecting because of the cursor reference R_LOC.LOCATION_GID.
when i hard code the value in the DML statemnt for the R_LOC.LOCATION_GID, the rows are inserted as expected. So i guess the way the procedure executes the value is not correct.
Modifying my select part which uses cursor variable R_LOC.LOCATION_GID under Insert statement.
select d.servprov_gid, d.depot_gid, replace(d.appointment_time,'':'') appmt_time, d.'||v_day_to_use||' DayUsed
from tesco_fresh_templates t, tesco_fresh_templates_d d, location_refnum r
where t.set_id= d.set_id
and d.depot_gid=r.location_gid
AND D.SERVPROV_GID=''R_LOC.LOCATION_GID''
and r.location_refnum_qual_gid=''TESCO.IVS SCHEDULING''
and (r.location_refnum_value=''YES'' or r.location_refnum_value=''Y'')
and t.default_set=''Y''

DECLARE
cnt number(10);
BEGIN
SELECT COUNT(*) INTO CNT FROM TBL_ADDRESS WHERE ADDRESS_ZIP
IN (SELECT * FROM TABLE(MY_PACK.STR2TBL('46227')));
DBMS_OUTPUT.PUT_LINE (cnt);
END;
MY_PACK.STR2TBL() is a function which takes '|' delimited string, extracts values and returns a table of zipcodes. The function works fine and returns 46227 but the count returned is 0 instead of 280(count returned by replacing inner select with '46227').

There are 2 Oracle databases with pseudo names Remote and Local. I have a function in Remote called FUS.F_Return_10 which simply returns 10 for testing purposes, where FUS is a schema name. In Local I want to create a procedure that will call the above function. Here's the PL/SQL:
CREATE OR REPLACE PROCEDURE TEST
(
V_COUNT OUT NUMBER
)
AS
V_FOO NUMBER(2,0);
BEGIN

There's a Public Database Link called PER_ACC in Local. When I try to create this procedure I get: Encountered symbol "@" when expecting one of the following: .(*%&................

I have a problem executing a function.
There are two tables,
1. Table with column names of a second table mapped to certain variables.
ex: Table1
col1, var1
col2, var2
col3, var3
--------
--------
2. Table with the values for columns as given in table 1 ex:
col1, col2, col3, col4, col5,
a , aa , 1 , x1 , p
b , ab , 2 , x2 , q
c , ac , 3 , x3 , r
I have to select values from table2.col1 do some processing and calculate values and store it in a table then do the same thing with col2 and so. This needs to be done for all the columns that appear in table1.For example in table 1 i have only three columns mentioned thus i have to process col1, col2 and col3 from table2. col4 and col5 will not be processed since they do not appear in the first table.
The problem is i have hundred columns in table 2 and the user can add up to hundred columns in table 1 as and when it is required.
I have created a cursor to first select column name from table 1 where variable is not null.For each value in cursor i put it in a local variable.
Second step is to select values from table2 where instead of column name i am using the local variable.But the problem is instead of choosing values from col1 the query returns the value as col1 (the value of local variable)
