We have two schemas which earlier used to be separate databases. There were DB links created to access the objects from one schema to the other schema when they were separate databases.
Since now they are just 2 separate schema with in the same Database, we would like to remove the DB Links and create synonyms to access those objects. These DB links were used in code in many places, it is becoming tough to find a way to implement this.
how to find all the objects that are using these objects or all the places these DB likns were being used.

I have a table with more than 200 columns. I would like to declare a cursor to query all the columns for each record (if c1%found then ....). As the table has more than 200 columns is it a good practice to declare a cursor

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;
[code]......
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 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).

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
testcursor BILL.refcursor;
ttstatus INT;
iSuccess INT;
returns INT;
TruncatedSQL1 VARCHAR2(32767);

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.

We receive hand punches (clock data) every day. Normally a person badges in(hand punch) which creates a row in the clock_tran_processed table. The information from that hand punch is the employee id (emp_id) the date hand punch occurred and a work_summary id (wrks_id). At the end of the day, the employee badges out (hand punch out) and another entry in the clock_tran_processed table is created. The new row will have the emp_id (employee name), date the hand punch occurred and the same work summary id from the morning.
Normally hand punches should occur in pairs. One in, one out... or one in, out for lunch, in for lunch, out for day. I am seeing intervals of three and five. Meaning the employee clocked in twice and out once, or in once and out twice. This shouldn't happen.
I am writing a report that will show number of clocks per for all employees that have three(3) or five(5) clock entries.I wrote a ref cursor that gives all the employees that have a count of 3 or 5 and the employee id (emp_id). I need to pass that employee id to another query that will then get me the dates of the clocks.Here is the ref cursor thus far (I am printing those with a count of 3 and 5).
CODEDECLARE
TYPE ClockTran_Refcur IS REF CURSOR;
ClockTran_cur ClockTran_Refcur;
NumClock_num number :=0;
NumClock_name clock_tran_processed.emp_id%TYPE;
[code]...
How do I pass that variable to the get the clktranpro_time's? I am using "Easy Oracle PL/SQL Programming" but I am not seeing this type of example(pgs 140-148).
