SQL & PL/SQL :: Write A Query Which Shows Data Of One Table Not Present In Other?
Apr 3, 2011
I am writing following query
SELECT DISTINCT a.list_type_code, a.list_type_name
FROM jls_list_type a, jls_list_control b
WHERE b.jalsa_srl = :jalsa_srl
AND b.list_no != a.list_type_code
ORDER BY list_type_code
I just want to display only those records from JLS_LIST_TYPE which is not present in other table JLS_LIST_CONTROL ... for this i wrote above query but it is not working.

Imagine a table below and I want to write a statement that shows time,name,ip,received and sent (SELECT *). (time, city, ip are primary key lets say).However there is the condition that I want:
It should be grouped for each CITY and I want to get max(RECEIVED) by descending order for each days. How can I do that?
select *
from table
group by city
having max(received)
Is it possible to get output without giving condition to other elements (IP, SENT... etc)
TIME- NAME- IP- RECEIVED- SENT-

We have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36%
Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.

I have created a wallet (11g R2 OEL 5.5) using the OWM.Tried opening the wallet (encryption_wallet_location set in sqlnet.ora). then while creating a table it said the master encryption key is not present. Have created the master key using the following command.
alter system set encryption key identified by "Password";
Here the strange thing i observed is that when we create a wallet using the OWM, it asks for the password and when i open the same wallet the master key is not created and it allows the master key to be generated with the same password that i have created the wallet in the first place with the OWM, with any other passwords it says that the wallet is not open.
After creating the wallet and creating the master key... I have the following questions, and its becoming quite hard to find the solutions as well.
1. Can we have multiple encryption keys... say i want to encrypt a table or column with one key and other with an another key.
2. How many keys can we have for objects in the table? or can we have only one key and many certificates.
3. wallet created, and encrypted tables present, the wallet is not in auto open mode, but somehow the database open after it is shutdown, here no encrypted tablespaces are present.
4. while creating an encrypted tablespace the default storage (encrypt ) has to be added to the add tablespace clause.

I have employee, location, city tables, I have written following code to use joins
select ename from employee e, location l, city c
where e.c_locationid= l.locationid and l.cityid= c.cityid and c.cityname='XYZ';
The same can be written by using non- correlated sub query as follow..
select ename
from employee
where c_locationid in (select locationid from location where
cityid in (select cityid from city where cityname='XYZ'))
I need to implement the same concept using correlated sub query...

I have to write a sub query / build a logic for the below.
There are several accounts which should have a zero balance i.e sum of all the amoutns in that account should be zero. If they are non zero , i have to report which amounts make up non zero balance.
If i have amts as +20 , -20 , -30,-10 i.e the sum is -40 indicating a non zero amount. I need the entire details of the records which makes up non zero sum. So in above case details related to -30 aand -10.
I'm using a sum group clause on several fields at which sum is required to be checked ie. date , account , currency . query that will bring individual records that don't make the sum zero.
Is it possible to write a outer query which will bring individual records which don't sum up to zero.
