OPENING CURSOR WITH TABLE NAME AS PERAMETER

hi all,
here i have a problem. please help me.
create or replace procedure MAX_ID
(COLUMN_NAME IN VARCHAR2,
TABLE_NAME IN VARCHAR2) IS
CURSOR MAX_CURSOR IS SELECT COLUMN_NAME FROM TABLE_NAME;
begin
END;
in the above procedure table name and column name are in parameters. I have to declare cursor with the in parameter values. How to solve this problem. Give me solution as soon as possible. Waiting for your valuable suggestions.
with regards,
vali

Hi,
You will need to use dynamic SQL to be able to do that. This one returns a single row but you may need to work more on this to achieve the results which you are looking for based on your requirement.
PROCEDURE get_data_dynamically_pr(pv_sqlstr VARCHAR2,pn_count IN OUT NUMBER) IS
ln_cursor NUMBER;
ln_rows NUMBER(5);
BEGIN
/* Retrieve the count from a table we passed */
ln_cursor := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(ln_cursor, pv_sqlstr,DBMS_SQL.NATIVE);
DBMS_SQL.DEFINE_COLUMN(ln_cursor, 1, pn_count);
ln_rows := DBMS_SQL.EXECUTE(ln_cursor);
IF DBMS_SQL.FETCH_ROWS(ln_cursor) = 0 then
RETURN;
END IF;
DBMS_SQL.COLUMN_VALUE(ln_cursor, 1, pn_count);
DBMS_SQL.CLOSE_CURSOR(ln_cursor);
EXCEPTION
WHEN OTHERS THEN
RAISE_APPLICATION_ERROR (-20400,SQLERRM||'Exception raised in dynamic sql proc..');
END;
I hope this might be useful to you.

Aftershotz,
You're going to have to give a bit more information.
What do you mean by "opening a file in library?" There is no function of Aperture to open files -- you can open (switch) libraries.
You'll have to be more specific about error messages, too. Perhaps some screenshots would be useful to diagnose your problem. "Can't open database with library name" is not enough detail about what Aperture is really telling you.

Problem with table name lengths.

Has anyone experienced with table name length problem?
When tables are created with schema registration, and the name is longer than 14 characters, the table is created. But when I "select * from xxxx_xxxx_xxxx_xxxx" it says that the table doesn't exist.
What's the max length of a table name? Or is this a problem with XDB?
Thanks,
Benjamin

Found the problem.
All table names must be all capitalized and seperated with underscore.
Is there something I need to set in oracle? or is this a bug? The tables are created but can't be accessed because of the case of table name... that doesn't make sense.

Maximum Open Cursors with the CachedRowSet

Hi all,
I have a simple task that is cause significant headaches. I'm using the CachedRowSet to process records from an Oracle 8.1.6 database. The code simply populates the row set with records, makes changes to 2 or 3 fields in each record, then calls the acceptChanges().
When I process about 200 records, everything works fine. If I try to process 300 records, I get the error
"ORA-01000: maximum open cursors exceded".
Right before the acceptChanges is called, there is only 1 cursor opened ( I'm checking this via the V$OPEN_CURSOR table). After the acceptChanges is called, it throws the error. Inside my catch block, I put a loop in to print the open cursors. All but two of them is from my app and showing the exact same SQL, update table set name ....
I have tried populating it directly and through a ResultSet, neither work. When I do a similar process using a ResultSet by itself, it is fine.
If anyone could please suggest what I might be overlooking I would appreciate it. Also, I would also like to know if there is someway to examine the specific SQL that is being sent to the database if possible.

we've had similar problems with Oracle creating and not destroying its own cursors("under the covers"). There is relevant info at the following link:
http://forums.java.sun.com/thread.jsp?forum=48&thread=135291
quick checklist:
1. close all statements/preparedstatements/resultsets explicitly and immediately after you are finished with them
2. increase your number of open_cursors in init.ora file
-->we had to increase ours to over 700 at one point.
3. commit/rollback explicitly when finished transactions.
hope this helps

Opening two cursors using open cursor with bulk collect on colections ..

Is it possible to have the implementatiion of using bulk collect with collections using two open cursors ..

GR/IR: Open receipts with vendor name

Hello SAP Gurus-
I am not sure if we are doing something wrong but we are currently reconciling our GR/IR account and what we noticed is that when we added the vendor name to the report with the help of an OSS note, we noticed that it gives us all transactions that make up the balance however it isn't what we wanted exactly.
What we were looking for was once we execute MR11 and handle all differences, we want to see only open receipts with the Vendor name. How can we achieve this? Is there a report? Should the GR/IR account be set up as a clearing account?
Any help/ insight is greatly appreciated!

Dynamic SQL Statement with table name

Dear all
i like to have a SQL statement with a dynamic tablename. Is this possible? If yes, how?
should be something like "select * from <mytablename>"
Thank you
Herbert

Yes this is possible. use the below reference code for this.
data: g_tablename type w_tabname,
gv_dref TYPE REF TO data.
FIELD-SYMBOLS: <g_itab> TYPE STANDARD TABLE.
gv_tabname = p_tablename (take table name form selection screen or as per ur requirement)
CREATE DATA gv_dref TYPE TABLE OF (g_tabname).
ASSIGN gv_dref->* TO <g_itab>.
now use the below select query to fetch the data
SELECT * FROM (gv_tabname) INTO TABLE <g_itab>.
Hope this will help

Prefix with table name

I have a query which involves two tables with both have some common columns ..I thought that if we don't prefix column names with the table names we would get a "column ambigously defined" error so that we will know that we need to prefix that column name with the table name. But I am not getting this error and instead I am getting wrong results as a consequence of not prefixing the column name with the table name.
Is this usual? How do I avoid this?

select emp_id from emp e, dept d
where e.emp_id=d.emp_id

Difference between with table name with * and without *

Hi..
I had seen some of the standard abap that the table name had *, like *ekpo. What is the meaning? What is the difference between with * and without * ?
Thanks and Regards,
Rishika

Hi rishika,
1. This is actually a facility provided in abap syntax.
2. It is usually checked while saving a record.
3. For eg.
If we have one variable
EKKO
and another *EKKO
(They both are same only, with same structure)
(but two different variables)
4. The functional meaning, for usage purpose,
of *EKKO is OLDEKKO.
5. While saving the transaction,
the data is saved only if there is any change
in the values.
IF EKKO <> *EKKO.
*--- SAVE
ELSE.
MESSAGE 'NO DATA CHANGED'
ENDIF.
6. We can aswell use any other variale
eg. oldekko
oekko
myekko
etc,
7. But for business meaning,
R/3 has the facility for *
1. we can use almost everywhere.
2. just copy paste
report abc.
TABLES : T001.
TABLES : *T001.
DATA : ITAB LIKE EKKO.
DATA : *ITAB LIKE EKKO.
DATA : NUM TYPE I.
DATA : *NUM TYPE I.

Sql Except query to Display mismatched records along with Table names

Hi
I am using below query to display mismatch records between two tables
SELECT * FROM table1
EXCEPT
SELECT * FROM table2
UNION
SELECT * FROM table2
EXCEPT
SELECT * FROM table1
This displays mismatched records like below
Sunil 1000 india
Sunil 1500 india
I would like to display even the table names in the result For ex;
Sunil 1000 india Table1
Sunil 1500 india Table2
Can you please help us in this regard.

cnk_gr's query should work for you.
One change that I would make is to use UNION ALL, not UNION. UNION eliminates duplicate rows, which means SQL has to do additional work (sort the result and then check for duplicates).
So if you can have duplicates and don't want them in your result, then you would use UNION. And if you can have duplicates and you want the duplicates in the result, you would use UNION ALL. But in cases like this, where you know you cannot have
duplicates (because column 1 contains 'TABLE1' for every row in the first half and column 1 contains 'TABLE2' for every row returned from the second half of the query), you should always use UNION ALL. It will be more efficient.

Join of cursor with table

Hi experts,
Oracle Version: 11GR2
I get dataset in the ref cursor as an out parameter from a procedure. Now, I have to derive column "NAME" from table "TEST" using ID as a join key between cursor and a table.
How can we do this in oracle?
Thanks

You cant join a cursor to a table. cursor is a SQL work area where instruction to execute a SQL is processed.
I could think of three approaches
1. The best way is to include the table "TEST" in the original SQL that builds the cursor.
2. If that is not possible then you need to fetch them (may be) into a SQL collection type and then join the table "TEST" with the collection type.
3. Or you may have to loop thorough the cursor and then for each row fetched you would have to join with the table "TEST"
Lets say this is your procedure
create or replace procedure getdept
p_out_rc out sys_refcursor
as
begin
open p_out_rc for
select deptno
    from dept;
end;
Example for 2nd approach
Create a SQL Nested Table.
create or replace type deptno_tbl as table of number(10)
And you write a PL/SQL code like this. Code in red is the one to consider.
SQL> declare
2    l_deptno deptno_tbl;
3    l_rc     sys_refcursor;
4 begin
5    getdept(l_rc);
6    fetch l_rc bulk collect into l_deptno;
7
8    for i in (
9               select ename
10                 from emp e
11                 join table(l_deptno) t
12                   on e.deptno = t.column_value
13             )
14    loop
15      dbms_output.put_line(i.ename);
16    end loop;
17 end;

6    loop
7      fetch l_rc into l_deptno;
8      exit when l_rc%notfound;
9      for i in (
10                 select ename
11                   from emp e
