example to use temp table in function with only ref cursor.
I need to use for the reporting purpose.
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;

iSuccess INT;

One of our customer have problem with following sql statement:
SELECT c.table_name, c.column_name
FROM user_tab_columns c, user_tables t
WHERE c.table_name = t.table_name
AND c.data_type IN ('CLOB', 'BLOB');
During execution it takes all the TEMP tablespace size(8GB).
I gather system stats (dbms_stats.gather_dictionary_stats(estimate_percent=>null)) but it doesn't resolve problem.Above sql statement works fine with RULE hint but I want to know what is the reason of problem with temporary tablespace.
I am trying to run on Oracle report via Oracle Application Concurrent job. Concurrent job is completing normal but I don't get anything on print out page. In log file of this request I see message 'MSG-01003: Errors =>ORA-01652: unable to extend temp segment by 128 in tablespace TEMP'. I almost doubled the TEMP tablespace in size but still I am not able to get rid of this error message.

this huge report that uses inline views. I keep getting the following error message when running the script through toad. I was thinking about using the USE_HASH hints. The sql optimizer we use is very buggy in Toad. I'm using oracle database version 10.2.0.3.
I can upload explain plan if needed.

abc_reports in this pack "ab_report" it is the function it having the ref cursor as out parameter . when am executing the above anonymous block am getting the below error,so how can i print the out ref cursor data in my block.

I've seen several code samples that show how to return a REFCURSOR from a Stored Function, but when I try it with C# it gives me allways WRONG NUMBER OF ARGUMENTS or somehing like that.
I presently don't have my code in here, but it is something like this:
cmd.Parameters.add ("parRefCursor", dbresult.RefCursor, direction.Result);
I'm being able to use it as a OUT parameter, but I would like to have it as a RETURN value from a Function.
To display highest marks,least marks,average marks,total marks of the student name entered.
desc stud;
Name Null? Type

SID NUMBER

How do I do that using PL/SQL and without Cursor.
know if there's a built-in function to covert an Oracle CURSOR to VARCHAR? Or how about a XMLType to VARCHAR?

What is the Best option for SQL/sybase server Temp table to use/for data manipulation (Insert/update/delete) inside the procedure in oracle Other then global temporary table.
Since we are porting from SQL/Sybase to Oracle we don't want to Create too many global temporary table.
what are minimum privilege required to create GTT (Global Temp Table)?

I'm having some trouble dealing with the PL/SQL coding. At the moment, I have a file (set of data) that is read using java. An array is created (line by line) and is passed into a temp. table, which is then called by the plsql (call PKG_xxx.PRC_xxx...) script/command for processing. Is there any way I could directly get the file loaded into plsql (into a temp. table maybe?)
The data are just numbers and letters. I already got the PL/SQL part to select the set I want for different cases. All I need is to get the file (directly or indirectly) for the procedure without going through java.
I need to create a temp table within a stored procedure. I want to apply some logic on the table, and then delete it when it is completed in runtime -- all inside the stored procedure.

We are using a GTT table to store the summarize data and display it on same screen(10g 10.2.0.5). Now we are facing temporary tablespace space issue very frequently as our client do not enable the auto extend on for temp table space. We have analyzed the AWR and came to know that there are 900000 inserts per hour on an average. Client DBA Claims that there are sessions(1or 2) which inserts the data in temporary table continuously for 2-3 days.
According to him one session is running from 28th Aug and problem comes on 2nd Sep and after killing the problematic session the application will work fine. Generally this problems come on weekend. I have discussed with our dev team and as per them there is no session leakage issue.
following is the insert statement:
INSERT INTO DT_CA_STNDALN_DETAILS_TMP (ORG_ID,BA_PRODTYPE_ID,MAX
TENOR,GROSSLIMIT,GROSS_UTILISATION,HAS_MDR,HAS_CLUSTER,SIGN_IN
D,GROSS_AVAILABILITY,COLLATERAL,NET_UTILISATION,DT_CA_STNDALN_DE
TAILS_TMP_VER,DM_LSTUPDDT,NET_AVAILABILITY) VALUES (:1,:2,:3,:4,
:5,:6,:7,:8,:9,:10,:11,:12,sysdate,:13) ;
What is the need of Temp table in Oracle ? what is the advantage of Temp table over normal table ? Is temp table a log operation one. What is the scenario of using temp table in real time ?
