Get Parameters Only Specify To SQL
Jun 14, 2013
Oracle Version:11.2.0.3/ OEL 6.1
For diagnosing a performance issue related to a batch run, our application teams wants to know all session/system level parameter that affects SQL performance. I can't simply give an output of v$parameter.name and v$parameter.
value as there will lots of parameter not related SQL performance like
diagnostic_destlog_archive_dest_1deferred_segment_creationcontrol_filesbackground_core_dump
I am looking for only those parameters which are relevant to SQL performance, like
optimizer_modestatistics_levelmemory_targetsga_target

How can you use pivot with a parameter? If you attempt to use a parameter then an ORA-500: bind variable not supported is given
Below is a simplified version of the sql to illustrate teh problem.
create table test_pivot
(
ord_no number,
qty number,
loc varchar2(10)
):
insert into test_pivot values (123, 3, 'LOC1');
insert into test_pivot values (123, 2, 'LOC1');
insert into test_pivot values (234, 4, 'LOC1');
insert into test_pivot values (234, 5, 'LOC1');
-- this one is fine
Select * From
(
Select Ord_No, Qty, Loc
From Test_Pivot
Where Ord_No In ('123', '234')
)
Pivot (Sum(Qty) For Ord_No In ('123', '234') )
-- how to use pivot with parameters
Select * From
(
Select Ord_No, Qty, Loc
From Test_Pivot
Where Ord_No In (:Ord1, :Ord2)
)
Pivot (Sum(Qty) For Ord_No In (:Ord1, :Ord2) )

I just upgraded my version of my oracle from 9 to 11.2g.When I tried to execute some queries in PL/SQL i keep getting an
annoying error : "ORA-01843 not a valid month."
I realized that if I execute the following query:alter session set NLS_DATE_LANGUAGE=AMERICAN;before every query that I want to execute, then it's executed fine.
I preformed the next queries:
1. select * from nls_database_parameters;
2. select * from nls_instance_parameters;
3. select * from nls_session_parameters;
and I saw that the fields in the "nls_session_parameters" vieware not derived from "nls_database_parameters" "nls_instance_parameters".
How can I derive the parameters from the instancedatabase view into the session view?I want that the "nls_date_language" parameter will always be 'AMERICAN'.

How to how to get this sql to work?
select a.in_house_ref
from media_item a
where
((&rack is null) or a.in_house_ref in (&rack));
--a.house_media in ('CH127600','BF101042'), example values
I've tried the a.in_house_ref in (:rack) by itself and that doesn't work for the values above and hence changed it to (&rack) and that works. The issue I run into now is that the the paramater can be null, ie., no values need be entered by users and hence I put the is null statement. When I run the full statement above, oracle returns an error, i.e. , ORA-00936: missing expression.

I have excel file which I am reading through plsql procedure using UTL_FILE utilities, one of the column in the excel has multiple values in the same column, I am getting the values into plsql, but when it is coming to where clause its not working.
Example:
in excel the column has : 'ABC','GEH','HGT',LTP'
create or replace procedure abc(temp_col varchar2)
.
....
....
...
SELECT COLA, COLB, COLC
FROM TABLE_TEMP
WHERE TCOL IN temp_col;
This is not working, if the column in excel has one value say ('ABC') then the above sql is working, if it has more than one value its not working.

i have a function which takes in two variables and return a varchar.
ex: Function(var1,var2) return as varchar2.
in the function,i query a table for var1 and var2 and concatenate the result set to return a varchar. But if either var1 or var2 is null,then my query in the function fetches the result set for the other variable.
My question is,how would i pass a null value through the function and handle it in the function.

The function definition in PL/SQL has IN OUT parameter as well as return statement. Using both we can return the values. Basic definition of a function is function can return only one value at a time.
The question is, Can we return a number thru return statement and a char value thru INOUT parameter. Is it possible to return two different values using these?

I am currently studying a Foundation degree in computer software development, and one of my assignment in PL/SQL I am stuck on one of the tasks.
I have to create a procedure where one of the parameters needs to have a default value of one, if no value is entered when the procedure is called. I have trued to use the NVL function which worked when using a anonymous block, but now I have to convert that to a procedure. My problem is I'm getting an error.
The code for the procedure is
CREATE OR REPLACE PROCEDURE add_new_classes
(p_number_of_classes NUMBER := NVL(NULL,1), -- This will enter a default value of 1 if the user does not specify a number
p_course_id classes.course_id%TYPE,
p_period classes.period%TYPE,
p_frequency classes.frequency%TYPE,
[code]....
I then use this to test it
BEGIN
add_new_classes(1002,'first','daily',3002);
END;
and the error I get is
Quote:ORA-06550: line 2, column 4:
PLS-00306: wrong number or types of arguments in call to 'ADD_NEW_CLASSES'
ORA-06550: line 2, column 4:
PL/SQL: Statement ignored
1. BEGIN
2. add_new_classes(1002,'first','daily',3002);
3. END;

I want to calculate two parameters A and B which are interdependent. Unfortunately, my code is not working correctly:
create table temp_res1 as
select *

The correct result should be:
create table temp_res (rn integer, a integer, b integer);
insert into temp_res values(1, 5, 10);
insert into temp_res values(2, 11, 6);
insert into temp_res values(3, 7, 12);
insert into temp_res values(4, 13, 8);
insert into temp_res values(5, 9, 14);
insert into temp_res values(6, 15, 10);
insert into temp_res values(7, 11, 16);
insert into temp_res values(8, 17, 12);
but I get:
create table temp_res (rn integer, a integer, b integer);
insert into temp_res values(1, 5, 10);
insert into temp_res values(2, 11, 6);
insert into temp_res values(3, 1, 12);

1. Documentation says to set "_first_spare_parameter" to resolve bug 6904068. What should be the value if we actually see this bug occurring after applying the patch. How can we determine that we need this parameter to be turned on?
2. How can we determine we need to set "_third_spare_parameter"? How can we check if there is a regression on log files?

I'm on 11.2 DB and need to create an audit table that will be populated by DB triggers of other tables (after Insert,Update and Delete). The triggers will only ever be inserting data into the audit table. I have read that for insert only tables, you should define the 'pctfree' as 0. Is this correct? Do I need to set any other params (like pct_used) for tables only ever being inserted into?

I have 3 questions.
I have 11.2.0.1 database on Windows 2008 R2 SP1.
1) While connecting to the database as sysdba (sqlplus "/as sysdba"), it takes about 12 to 15 seconds what things I need to check/change so that connection will be faster?
2) Also, I have read somewhere that changing the sga/memory parameters connecting to the database. is it true?
3) This is not concerned with above 2 questions. What should be the memory parameters size for a 8 gb database?
What I have is:
Total System Global Area 1068937216 bytes
Fixed Size 2182592 bytes
Variable Size 1027605056 bytes

We are on a GRID DB and using Oracle 11g.
A external reporting application ( SQL SERVER REPORT SERVICES) sends in some comma separated parameter values, which has to be queried against a table with 6-10 million records.
Length of the comma separated value can go upto 5000-6000 in length based on user input in the front end application. This application sends this value in comma separated. i.e., like
'AA1-11101,AA2-34346,AA4-534399,.....' like this at a time the application can send upto 500 values each of length 10. i.e, maximum length can be upto 5000. I used CLOB to handle this because since the length can be 5000 and varchar2 can handle only 4000 long literals.
But the time taken by the CLOB to verify against the table using INSTR is more compared to VARCHAR2.
I found that VARCHAR2 does'nt take much time. Is it a good idea to have VARCHAR2 in the PLSQL procedure as parameter instead of CLOB, since PLSQL VARCHAR2 can handle upto 32000 long values.

I have to write a trigger on a table which contain lot of parameters.But i need to pick a specific row and check that without disturbing other stuffs.Is there a way to write Before update trigger on a particular rows filtering the unneccasary rows.
The requirement is when user update the date from front end (Java application) the trigger should check the date and validate that it should be month end date. For example.
1)04/21/2012 wrong date
2)04/30/2012 correct date
3)03/29/2012 Wrong date
4)03/31/2012 correct date

I am trying to figure out if the syntax for the "else" part of this code is correct... this will basically appear 12 times for each month of the year changing the value for month:
case when floor(sum(total_adjusted_net_amount)/100) < 0 and month in (01) then 0
when floor(sum(total_adjusted_net_amount)/100) > 29 and month in (01) and then 30
else when floor(sum(total_adjusted_net_amount)/100) and month in (01) end Groupin_01

I need to pass two parameters (STUD_ID) and (TERM) from Form A to Form B. I've read a lot but I'm not familiar with terms and oracle jargon yet! So I really need your straight forward clarification
From the Calling form I'm using when_button_pressed trigger...what shall i write in here?! In the Called form, I'm declaring the following under (When_new_form-instance):
declare
p1_id paramlist;
stud_id number(8);
term number(5);
begin
p1_id := get_parameter_list(stud_id);
p1_id := get_parameter_list(term);
:TEST_STUD_CRSE_REG.stud_id :=:parameter.stud_id;
:TEST_STUD_CRSE_REG.term :=:parameter.term;
next_block;
end;
-----------------
on the calling form:when_button_pressed I am using:
DECLARE
p1_id paramlist;
stud_id number(8);
term number(5);
BEGIN
call_FORM('test16SEP',NO_HIDE);
GO_BLOCK('TEST_STUD_CRSE_REG');
set_block_property('TEST_STUD_CRSE_REG',default_where,'STUD_ID=:TEST_STUDENT_INFO.STUD_ID');
