Cursors - Display Data Gathered From 3 Different Tables?
Apr 30, 2010
I am stuck somewhere in my project, situation is that we are trying to display data gathered from 3 different tables, we used cursors for this, here is the cursor declaration.
DECLARE
procedure DocInfoCur(myWhere IN varchar2) IS
init_dept_id number;
init_dept_name varchar2(40);
rcvg_dept_id number;
rcvg_dept_name varchar2(40);
CURSORCUR_DOCINFO IS
SELECT DISTINCT I.CTN, I.DIARYNUMBER, I.INITIATINGDATE, T.TYPENAME, I.INITIATINGDEPT,
I.DOCUMENTSUBJECT, I.DESTINATIONDEPT
FROM DOCUMENTINFO I, DOCUMENTTYPE T, DEPARTMENT D
[code]...
This displays all the records out there.
Now, I have a search form where I need to filter the same data with different parameters, I have compiled the entered data in one string, now i need to join that string at the end of where clause of my cursor, how can I do that, i have tried concatenating both but received compile error, is there a way out in the current scenario???

DB version: Oracle DB 10g Enterprise Edition 10.2.0.4.0
I have the following four tables:
tab_main- which lists main projects
tab_sub_main - which lists sub projects
tab_budget - amounts per projects/subprojects
tab_total - I want to load the data here
The table script with data is attached.
I want to load data into tab_total fields for prj_type= 'J' as follows:
1. accn_no from tab_main table.
2. fy from tab_budget table
3. fy_total_amt which is the sum(amt) from tab_budget table by accn_no and fy
4. all_FY_amt which is the sum(amt) from tab_budget table by accn_no
5. all the audit fields- date/user inserted/updated will come tab_budget table
how to create this procedure with cursors.
CREATE OR REPLACE PROCEDURE LOAD_DATA_INTO_TAB_TOTAL_PROC
IS
CURSOR C IS
select distinct m.accn_no, a.control_no,m.prj_type,
b.fy, b.amt, b.user_created, b.date_created, b.user_last_mod, b.date_last_mod
from tab_main m,
tab_sub_main a,
[code]....
CREATE TABLE tab_main
(
ACCN_NO NUMBER(7) NOT NULL,
PRJ_TYPE VARCHAR2(1 BYTE) NOT NULL
)
/
Insert into TAB_MAIN
(ACCN_NO, PRJ_TYPE)
[code]....

I'm using few cursors to update my data and store it back to the same table. But for some reason the cursor seems to be picking obsolete data.
cursor c1
is
select distinct roles
from table1
where flag = '1';
cursor c2
is
select distinct roles
from table1
where flag = '1';
begin
for i in c1
loop
here im updating the roles im picking to to a suffix and role.
update table1
set role = suffix_role
where 'some condition';
end loop;
commit; -- committing so changes are visible for my next cursor.
for j in c2
loop
here im deleting all the roles that are not part of my comparing table.
delete from table1
where role = 'something';
But in my debugging table i see that its deleting roles present as input for first cursor, whereas it should actually pick data with suffix_roles.

I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.

I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?

Here is how the data looks in the table now:

0007 898998 02/12/2011

When I transpose the data, it should look like this:

I have two methods using pro*c to execute a query SQL and read the results. The query is a "select from" a view, this view is a union between two tables. The first method creates a cursor and fetches the results line by line. A second method creates a cursor and fetches the results in parts.
Method 1)
CODEEXEC SQL FETCH Cursor1 INTO ...
Method 2)
CODEEXEC SQL FOR :numLines FETCH Cursor1 USING DESCRIPTOR areaDescSQL;
I had executed this methods in my development enviroment, using Oracle 11g, Suse linux. As I expected, the method 2 spent much less time than the method 1. But, in the "customer enviroment", using another database, Oracle 11g and HP-UX, these methods spent almost the same time.
Is there some Oracle's configuration or parameter's settings that maybe explain that? What configuration can be differente between the two databases? What can I do to improve the time spent?

I'm currently looking for a way to declare a cursor in the 'declare' block using a previously defined variable that got its value from a query. For instance:
declare
my_company_id INTEGER := 'select c.company_id from company_table c where company_name='Wal-Mart';
cursor employees is
select e.employee_id from employees e where e.company_id = my_company_id;
Any way to do this?

Web page that retrives data from SQL database and display it to the user in well formatted manner. Data retrieved depend upon criterias selected by the user. But sometimes data retrieved is very large. I want to display records to the user page wise, i.e. 100 records on first page and next 100 records displayed when user clicks next button. This means only 100 records should be retrieved when user first select search criteria, next 100 records retrived when he clicks next button and so on, as to reduce data transferred from server to client. how to achieve this by using single sql query as soon as possible.

How can we pass multiple parameters to cursors?
Ex: Cursor C_employees(C_empid number, C_cityname varchar2) is select emp_name, office_name from employee where employees where empid = c_empid and city = c_city_name;
I know we can pass one parameter to the cursor but I do not know how to pass multiple parameters.
