SQL & PL/SQL :: Normal Join And Outer Join
Oct 19, 2013Lets say I have three tables t1 and t2 and t3.
SELECT * FROM T1;
Id
____
1
2
3
4
SELECT * FROM T2;
Id
____
1
SELECT * FROM T3;
Id
____
1
Now when data exists in T2 and T3, I want to return only the records in T1 that match the records in T2 and T3 which is basically a normal join
select t1.id from t1, t2,t3 where t1.id = t2.id and t1.id = t3.id
However when there are no records in T2 or T3, I want to return all records in T1 i.e 1,2,3,4
One way of doing that is using the not exists clause
select * from t1 where not exists ( select null from t2 where t2.Id != t1.id) and not exists ( select null from t3 where t1.Id != t3.id)
Is there a better way of doing this in sql ?
SQL & PL/SQL :: Transform NOT EXIST Subquery In LEFT OUTER JOIN With Nested Tables?
Mar 22, 2012these are the sample data :
CREATE OR REPLACE TYPE CourseList AS TABLE OF VARCHAR2(64);
CREATE TABLE department (
courses CourseList)
NESTED TABLE courses STORE AS courses_tab;
INSERT INTO department (courses)VALUES (CourseList('1','2','3'));
[code]....
The query returns the correct data, CourseList that are not subset of any other CourseList of the table.
I am trying to convert this not exists in a left outer join query to check if the performance is better, but I don't know how to do it.
I was making some variations of this code :
select d1.courses c_1, d2.courses c_2
from department d1,department d2
where d1.courses<>d2.courses(+);
but it is now working.

View 3 Replies View RelatedSelect Statement Gives Different Results Using Bitmap Or Normal Index
Jan 10, 2012we have a strange symptom in a database Oracle 11.2.0.2 EE. Following question comes from our application developers.
The following SQL statement:
SELECT
v.reporting_month,
sum(v.f_s) "REV_S",
sum(v.f_f) "REV_F",
sum(v.f_c) "REV_C",
[code].......
gives different result when we exchange the index ksr_valid_until_i on table kreditkarten_sets_rs. For some reasons we changed the index from bitmap to normal and are getting different results. Switching back gives us the same results as before. When we avoid the usage of this index in the statement than we are getting the same results as when we are using the normal index.

Apr 24, 2012is it possible to login as SYSDBA in oracle forms from normal logon procedure?
logon(sys_acc, sys_pwd||'@'||:GLOBAL.db_conn);
The reason behind this is to make a form which will alter user's password. But all the users are in SYS account and it is necessary to login as SYSDBA in forms to execute alter statement.

Automatic Storage Management :: RAC 11gR2 - Normal Or External Redundancy

Automatic Storage Management :: Normal Redundancy Disk Group
Oct 3, 2013One of my collegues created an ASM disk group with normal redundancy using 2 disks. But the disks are not of same size, one disk is 100GB and another one is 10GB. Now the usable space out of diskgroup is showing 55GB. When I checked the diskgroup properties it is showing 2 fail groups one is DATA1_ 0000 with 10GB and other is DATA_0001 with 100GB. My question is why it is showing 55GB as usable space? My assumption is as it is having 2 fail groups with different disks of different sizes. For the failgroup 2 even it is of 100GB size, in order to maintain the redundancy with other small FG(10G) it will consider only 10GB out of 100GB. So, the 2nd FG size also should be 10GB. So that the usable space should show as 10GB as opposed to 55GB (not (100+10)/2).
