SQL & PL/SQL :: Pass Table Name To Cursor?
Dec 16, 2010
I want pass the tablename to cursor. The tablename will be a dyanamic one, as we have the data in different sources tables[multiple systems - all systems will provide the data dump to oracle] with same set of columns.
I have inserted all the tablenames in a parameter table and based on conditions daat should be fethced from each system.
I need to pass the tablename to the cursor to fetech the coloumn list from the table(the table that is passed as parametr).

Create a PL/SQL block that declares a cursor called DATE_CUR. Pass a parameter of DATE data type to the cursor and print the details of all the employees who have joined after that date.
DEFINE P_HIREDATE = 08-MAR-00
Test the PL/SQL block for the following hire dates: 08-MAR-00, 25-JUN-97, 28-SEP-98, 07-FEB-99.
I don't know how to pass parameters. So far I have this:
SET serveroutput ON;
DECLARE
p_HIREDATE DATE := 08-MAR-00;
CURSOR c_DATE_CUR(P_HIREDATE DATE) IS
BEGIN
OPEN c_DATE_CUR();

I am using regexp_substr to break the pipe delimited string. Want to use the output as the NUMBER input to a cursor.Its not working and not getting any error also.
Here is an example.
initial input : '5545|4124|12456'
using the sql below to break the string into columns.
select regexp_substr('5545|4124|12456','[^|]+', 1, level)) from dual
connect by regexp_substr(, '[^|]+', 1, level) is not null;
But when i try to pass the output of the above query to a cursor with input defined as number, its not accepting. I tried using to_number for the output of above query.

I have to create a function which count the max id in the provided table.
For example: I have two table customer and book
and
create or replace function Row_Count(tab_nam) return varchar2 is
CONTR_NO varchar2;
begin
select NVL(MAX(t.contract_num), 0) + 1
INTO CONTR_NO
FROM tab_nam t;
return(CONTR_NO);
end Row_Count;
when I call
Function( customer) ;
or
Function( book) ;
It should tell the max number with addition of one.

I have a problem here.Normally, we use &p_where inside a sql script in condition sectione.g :
select name from member where name like 'a%' &p_where order by name;
may i use this kind of parameter in table section?e.g :
select name from &p_table where name like 'a%' and status = 'a' order by name;
the reason i need to do is there are 2 different server. but i need retrieve same info.server ABC have table A but don't have table B and server DEF have table B but don't have table A.
Is there any other method to solve this problem?

I have to write a PL/SQL procedure, which is supposed to take an array of strings as input. This array will have simple strings as elements, like
'000887S','000780S'.
Now I have a query in the procedure, which will return a row, for each of the array elements. For example:
SELECT
su.EMPLOYEE_ID,su.FIRST_NAME,
su.LAST_NAME
FROM
USERS su,
[code]......
In the place of the '?' in the above query, the array elements have to be passed. So we will get one row from the above query for each array element.
Now we either have to loop through the array elements to fetch the result set for the above query for each array element, or we can use some other method too. Our objective is to collect all the rows of the above query for each array element as a table data and this procedure has to return this table set.
what will be the best way to pass such a set of data to the proc and best way for the proc to return this result set. Like we can use arrays, table type data,ref cursors, etc.

i am trying to fetch the cursor returned from a stored procedure and insert into a physical table. but i am unable to populate the table. below is how my code looks.
declare
p_out sysadm.CGF_PKG_REFCUR.rcDataCursor;
a table1.node%TYPE;
b table1.acct%TYPE;
c table1.descr%TYPE;

In the above, stored_proc is the stored procedure from OLAP database. Above code i am executing is from EPM database.
p_out returns a result set of (select a,b,c from table2).
I am trying to get the result set from OLAP database and populate a table in the EPM database.

I am working on a POC. The goal is to do a
select * from function('input')
where the function dynamically returns different tables.
I have gotten to the point where I can return the cursor but I cannot format it as a table to use in the query. It return's it as XML. This is my function:
create or replace
FUNCTION CAMS_FUN_GEN_REPORTS(PARAM1 IN VARCHAR2) RETURN SYS_refCURSOR AS
BEGIN
DECLARE
p_recordset SYS_refCURSOR;
begin
OPEN p_recordset FOR 'SELECT * from STATS_FLAGGED_TOTALS_ME';
RETURN p_recordset;
END;
END CAMS_FUN_GEN_REPORTS;
This is my query:
select * from CAMS_FUN_GEN_REPORTS('')
So normally you would do this
select * from TABLE(CAMS_FUN_GEN_REPORTS('') as tabletype)
But I will never know the end result table as it will be dynamic so I have to find a way to cast the result of the function into a new table I can select on.
I have looked into pipe lining also but from what I can tell you still need to know the table definition. Which I can't know from the client side. The server will control the 'routing' and thus the end result of the select.

We had an issue with a PL/SQL package taking hours to run as a concurrent program. Database version is 10.2.0.4.0, running on Linux x86 64-bit. A tkprof'd trace file revealed the problem SQL statement to be a cursor. This one SQL statement would run for 3+ hours. I copied the SQL statement and ran it in TOAD and it completed in seconds, returning the exact same result set. To resolve the issue in the PL/SQL package I created a global temp table and ran the exact same SQL statement as an INSERT into the global temp table.
Again, instead of hours, the SQL statement completes in seconds. If I revert the change, it goes back to taking hours. I've attached the relevant sections of the tkprof showing the two SQL statements (identical other than the insert in front of one) and the resulting explain plans and performance data. I've always been under the impression that a cursor was a better option than a temp table and I've never run into a situation where the same SQL statement runs so much longer when executed as a cursor.

I have strange problem when i try to return a ref cursor holding data from a select on a oracle global temporary table. If i iterate through the cursor , i can see the values but the function as such returns nothing through the ref cursor. I tried the temporary table as both delete on commit and preserve on commit
create or replace
PACKAGE BODY BILL AS
FUNCTION FILTERI RETURN BILL.refcursor IS

I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS
TYPE emp_cur_type IS REF CURSOR;
PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER);
END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value
from v$sesstat s, v$statname n
where s.statistic# = n.statistic#
and sid = 7
and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 4
opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 11 <----- 7+
opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors)
opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE
---------------------------------------------------------------- ----------
opened cursors cumulative 53 <----- 17+
opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded
ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.

I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is because of using a cursor having a value which is of old value. Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.
