When we create sql and some pieces of sql are implemented as oracle function. and we run this sql only once every day. I read article that function after first run located in cache. This part of cache ( with function ), is it really consume one oracle resources? Or it will be erased after while.
View 3 RepliesI have the following query.
sql

- sql Code
SELECT class, COUNT (class)
FROM nv_table
WHERE l_id IN (
SELECT l_id
FROM n_table
WHERE id IN (1234)
GROUP BY class
ORDER BY class
SELECT class, COUNT (class)
FROM nv_table
WHERE l_id IN ( SELECT l_id FROM n_table WHERE id IN (1234)
GROUP BY class
ORDER BY class
It returns two columns: class and the total number of values in that class.
In some cases, there might not be any values under a certain class, so the query won't return anything.
In such a case I want the query to return 0. So what I want to see is:
class:A, COUNT(class):0
I'm trying to use the NVL function here, but either it doesn't work in this context, or it's not the correct syntax the way I'm writing it.

I am trying to search a way to get the SQL statement that caused an exception withing an oracle function.
I tried:
SELECT sql_text

but this doesn't always return the last statement that the function has executed. if needed i can send the complete script for the function and its tables and stored procedures for testing.

In the below SQL, I am calling a function "listagg_nm(deptno)", and function is to get all the employee name for a particular department with comma separated
output is:
-------------------------------------------------

10 1300 KING,CLARK,MILLER
10 2450 KING,CLARK,MILLER
20 2975 JONES,SCOTT,FORD,SMITH,ADAMS
[code]....
below are the code
select deptno,sal,listagg_nm(deptno) from emp order by deptno;
FUNCTION listagg_nm (p_deptno NUMBER)
RETURN CLOB
IS
v_str CLOB;
[code]....
My doubt/question is for every row in the SQL the function is being called. t means that for 1st row deptno=10, the function is called and return all concatenated name for department 10, then again for 2nd row deptno=10, it again do the same, similarly for all other department.
Can we avoid this, I mean, if function is already returned a concatenated string of ename for deptno=10, then in the next function call it will checks if it is for same department (i.e. deptno=10) then the function will not go into for loop and it will directly return the concatenated string of ename for deptno=10 which we already done for the first row and so on for other department number ( something like storing the value in variable. Is it possible to achive this and does this is good for performance as we are not going into loop inside the function to return the concatenated string of ename for the same deptno everytime ( I have to return more than 10000 char., so i used clob in function and similarly the numbers of row return by SQL is more than 1000)and also how to code this, I tried but unable to achive.
I have an issue with rather complicated function.Basically it is using DBMS_SQL to execute a very long statement with many parameters (~6000 of them) and binding them with DBMS_SQL.BIND_VARIABLE. Variables are called :1,:2,...,:6000.
When this arguments set is too large - I am receiving error "ORA-00939: too many arguments for function".
Currently I am thinking about dividing the query into subqueries and executing them all with performance decrease.
I am encountering error in this code.

How to call a function with a row type return in an Oracle select statement.
For e.g. :
If I had this function with a rowtype return:

How could I use this in a select clause, as there is a multi column return by the function ?
Currently I am working on conversion project. We want to verify the both applications updated database values are same or not.
if you run same transaction in both application values are updated in the database. I want compare both database tables, its updated same values in table or any mismatch in the table, is there any tools available right now to compare the two rows values in same tables.

from the above query i was expecting value '2' but its returning '1'. As I am using TO_CHAR its trying to compare characters. Is there a way, to compare times alone like less than, greater than?

I need to populate a table based on the results of comparing sets of data. I decided to do this using MULTISET EXCEPT, but having created the structure, do not know whether it is actually possible, and if so, what syntax to use.
I have created:
CREATE OR REPLACE
TYPE NUMBER_TBL IS TABLE OF NUMBER;
/
CREATE OR REPLACE
TYPE PACKAGE_OPTION_GROUP_OBJ AS OBJECT( ID NUMBER, benefits NUMBER_TBL )
/
CREATE OR REPLACE
TYPE PACKAGE_OPTION_GROUP_TBL AS table of PACKAGE_OPTION_GROUP_OBJ
/
I have populated the following:
selectedTable PACKAGE_OPTION_GROUP_TBL := PACKAGE_OPTION_GROUP_TBL();
defaultTable PACKAGE_OPTION_GROUP_TBL := PACKAGE_OPTION_GROUP_TBL();
groupTable PACKAGE_OPTION_GROUP_TBL := PACKAGE_OPTION_GROUP_TBL();
comparisonTable PACKAGE_OPTION_GROUP_TBL := PACKAGE_OPTION_GROUP_TBL();
Once populated they contain the following data:
***selectedTable***
GROUP_ID : 121
BENEFITS : 161
---------------------------
GROUP_ID : 123
BENEFITS : 165
BENEFITS : 167
---------------------------
***defaultTable***
GROUP_ID : 121
BENEFITS : 161
---------------------------
GROUP_ID : 122
BENEFITS : 162
BENEFITS : 163
---------------------------
***groupTable***
GROUP_ID : 121
BENEFITS : 161
---------------------------
GROUP_ID : 123
BENEFITS : 165
BENEFITS : 166
---------------------------
I first need to compare the ID field only of selectedTable with defaultTable to find where they differ, something like
comparisonTable := selectedTable MULTISET EXCEPT(ID) defaultTable
I am expecting the result to be something like:
***comparisonTable***
GROUP_ID : 123
BENEFITS : 165
BENEFITS : 167
---------------------------
However, I don't know if this is possible and if so, what the syntax would be.
At a later stage, I will need to compare the benefits between selectedTable and groupTable, where the GroupID's match, which is why I have the tables structured in this way.
I ran SPA for SQL workload of around 94 SQLs.In comparison report that is generated by SPA, there is a metrics "Top 94 SQL Sorted by Absolute Value of Change Impact on the Workload".

I am using swingbench tool to generate load on DB and using OLTP like benchmark i am comparing the performance of plain data and encrypted data.
I have created two different database. one for tde and other for plain. I have populated same number of rows in both databases. Then i start running the benchmark and i use SAR to collect disk I/O's, VSAR to CPU usage.
From the sar report it seems that,
Oracle plain has faster transactions, it uses minimum CPU. But when look in tot the Reads/Writes TDE has lower than the plain.
If TDE needs to encrypt the data to store in the disks it should occupy more space than the plain data. Then the I/O should be more in TDE..
Note: Bcz the DB parameters are same, number of rows in the tables are same. File system and its block size are same. I will run the swingbench seperately for both the databases.
I am attaching the excel sheet for sar results. Let me know if you need more information
My primary objective was to compare objects in schemas in two different databases and find out the differences, Execute DDL's in the database where objects are missing and syn schemas in two different databases.
So I need to compare schemas in databases. Which tool will be user friendly to make a comparison of database objects existing in schemas in two different databases.
I'd like to see if I can get a list of pro and cons between Toad and SQL Developer for comparing schemas pros and cons. How to make a comparison. I have some idea on using TOAD but was not familiar with SQL Developer.
Below is my requirement:-
Connect to Source
Connect to Target
Compare schemas with different object types
Find out differences
Generate DDL's for the missing objects or for the objects in difference report
Run them in missing instace(Source/Target)
Make sure both are in sync.
Could it be that it's impossible to change the date format in the default_where clause?
The table column PROPOSAL_END in the database that I want to compare with, is in Format DD.MM.YYYY.
I tried:
set_block_property('Tours' , default_where, 'Number_of_places > 0 AND PROPOSAL_END <= ' || to_char(to_date(sydate,'DD.MM.YYYY')));
set_block_property('Tours' , default_where, 'Number_of_places > 0 AND PROPOSAL_END <= ' || to_char([-- A date item with the intial value $$date$$ the output is in Fomat DD.MM.YYYY by default --]));
set_block_property('Tours' , default_where, 'Number_of_places > 0 AND PROPOSAL_END <= ' || to_char(to_date([-- A date item with the intial value $$date$$ the output is in Fomat DD.MM.YYYY by default --],'DD.MM.YYYY')));
It all does dot matter. Every time the generated select-statement shows the format DD-MMM-YY. How can I change that?
I have a below requirement to compare the development and production objects.if any association_type or association_role are not exists in production then i need to return a message like "the Type Object found in Development,but not Production"
Below is the tree structure
development
ProcessingSite(Association type1)
TreatingSite(role1)
MoodedActivity(role2)
MaterialName(role3)
production
ProcessingSite(Association type1)
TreatingSite(role1)
MaterialName(role2)
Processing Site is an association_type and it is having 3 association_roles. we can observe same association_type in the production, but Mooded Activity(association_role) is not available. in this case we need to return "Type Object found in Development,but not Production".
We have migrated database data from physical servers to virtual servers. i want to ensure all database parameters are set correctly in both physical and vblock servers.
