I am looking for an explanation for having the following query:
SELECT PK_SERIAL_NUMBER FROM TABLE1 MINUS (SELECT FK_SERIAL_NUMBER FROM TABLE2);
Which normally returns the values of SERIAL_NUMBER that are not passed to the child table TABLE2
and the query:
SELECT PK_SERIAL_NUMBER FROM TABLE1 WHERE PK_SERIAL_NUMBER
NOT IN
(
SELECT FK_SERIAL_NUMBER FROM TABLE2
);
which returns 0 rows!
where difference lies between these operators or clause, & whether there is any "except" operator in oracle, i know other three are used bt dont think oracle uses "except" too..as far as i have seen "NOT IN", "MINUS" , "NOT EXISTS" are exactly similar?

I can achieve same results using either one of them.
I got a two tables, table the_table_1 consist of customers and the other one the_table_2 consist of channels.
And I need to get list of channels by contract which are an assigned to customers.
The select below give me a only assigned channels but I need to get a contract_key too from the_table_1.
select o.channel_name from the_table_2 o
minus
select o.channel_name from the_table_1 a, the_table_2 o
where a.contract_key=237092201
and a.offer_channel_key=o.OFFER_CHANNEL_KEY
And the select under (after minus) gives a list of non assigned channels by contract_key:
select o.channel_name from the_table_1 a, the_table_2 o
where a.contract_key=237092201
and a.offer_channel_key=o.OFFER_CHANNEL_KEY
how to rewrite a select to get required result?
I have a two tables with same column name , I wanted to find different record in table1 when compared with table2
create table table1(col1 number,col2 number,col3 number,col4 number,col5 number);
create table table2(col1 number,col2 number,col3 number,col4 number,col5 number);
insert into table1 values(1,2,NULL,NULL,NULL);
insert into table2 values(1,2,NULL,NULL,NULL);
commit;
select col1 from (select col1,col2,col3,col4,col5 from table1 minus select col1,col2,col3,col4,col5 from table2);
no rows selected
how come i get no rows selected when col3,col4,col5 is having null values but NULL could be anything so
NULL-NULL cannot be equal to zero how is it possible
I wish to delete records found with function MINUS from file1, which is a result of records not found in file2.
Both codes are taken way too long.
ps. none of the columms are unique, and some records have no value in some columns
DELETE
FROM file1 y
WHERE EXIST (SELECT *
FROM (
SELECT a.col1, a.col2, a.col3, a.col4
FROM file1 a
[Code]....
i have two tables having some fields .In table table1 there is 2 lakh rows and in table table2 there is 3 lakh rows.In both table 2 lakh rows are common.I have to find those 1 lakh rows which are distinct but the condition for this i have to use only sql joins not minus or subquery or any function.
when i doing this.select t2.id,t2.name,t2.loc from table1 t1,table2 t2 where t1.id <>t2.id;
I have 2 questions for this SQL Statement for tuning?
select * from a where id not in (select a_id from b)
1- How do i change this query with A MINUS OPERATOR
2- Shall i use a Hint for this query?

I am using the below query to show the difference of data between two tables using minus operator.
teh result is correct, but is there a way can it show with a flag with new rows and updated rows something like "N" for new row and "U" for updated row.
select CURRENT_STG_GLACCTS.TABLE_NAME,
CURRENT_STG_GLACCTS.ACTIVE,
CURRENT_STG_GLACCTS.BUSINESSUNITID,
CURRENT_STG_GLACCTS.COST_CENTER,
CURRENT_STG_GLACCTS.GLACCT,
[code].......
create a procedure so that I could get minus query of 2 table as a result.
I have two table 1- src_table_list ,2- tgt_table_list both tables have 2 columns : serial_no,table_name and 100 records each. and details mentioned in column "table_name" are actually tables name which present in my testing database.
so I need one procedure which will pick one table_name from src_table_list and one table_name from tgt_table_name each time recursively and provide minus query as a result. as below.
select c1,c2,c3,c4 from table1 --(fetched from src_table_list)
minus
select b1,b2,b3,b4 from table2 --(fetched from tgt_table_list)
create the procedure..as I have to prepare minus query for more than 200 tables and then I need to test them for integration testing..
Detail table will look like below:
Product_id issue_date action_date Force_date
1 10/10/2012 10/10/2012 10/10/2012
2 10/10/2012 10/10/2012 10/10/2012
3 10/10/2012 13/10/2012 15/10/2012
[code]....
Need the data like
Issue_date count_action_date count_Force_date (diff(action_date,force_date) 1 2 3 4 5 6(days since over)
10/10/2012 3 4 1 4 2 1 0 0
How to get the data like this? automatically how to get 123.... and how to calculate the difference by which day the count of difference is going?
I am searching the simplest way for ad hoc MINUS.I do:
SELECT *
FROM uam_rss_user_XXXXXXX
WHERE host_name IN
('XXX0349',
'XXX0362',
'XXX0363',
'XXX0343',
'XXX0342',
'XXX0499',
[code]....
and look in the table which values are missing (values that are in host_name IN but not in actual table).is there a simpler way for doing an ad hoc MINUS? I know to insert values in temp. Table. How are experienced Oracle pros doing this task?
Here is script of tables
Quote:drop table p;
create table p (qty number(3), beg_no number(5));
insert into p values(5, 110);
insert into p values(8, 786);
drop table s;
create table s (used_no number(5));
insert into s values(111);
insert into s values(113);
insert into s values(791);
Table p: it has ticket quantity and ticket begining number. Thus according to first record ticket number will begin at 110 and will end at 110+5 (Beg_no +qty). According to second record ticket number will begin at 786 and will end at 786+8 (Beg_no +qty). This table can have many records.
Table s: it has ticket numbers which are sold. The ticket will always be any number from table and will lay in any record in this format between beg_no and beg_no+qty
Required: I want "p MINUS s" information. i.e.
Quote:
110

114
786

I encountered this problem when we recently migrated to 10g. The table nametab has two columns roll(number datatype) and name(varchar2(10) datatype).Following are the queries used and I have deliberately not given space between the "select" clause and the "from" clause.
In 9i
SELECT name,1FROM nametab where rownum < 2
NAME 1
---------- ----------
Bharath 1
Same query in 10g
SELECT name,1FROM nametab where rownum < 2
ORA-00923: FROM keyword not found where expected
Here, I have interchanged the select columns.
In 9i
SELECT 1,nameFROM nametab where rownum < 2
ORA-00923: FROM keyword not found where expected
In 10g
SELECT 1,nameFROM nametab where rownum < 2
ORA-00923: FROM keyword not found where expected
what are difference in between oracle 9i and 10g regarding with Sql queries?

When I use this sql: CREATE USER testuser IDENTIFIED BY "welcome1 " to create user in Oracle DB 11.2.0.1.0. I can login with testuser/welcome1, please notice the welcome1 is not end of black space in login.
But when I do the same thing in Oracle DB 11.2.0.3.0. I can't use this user login with any password. I tried welcome1, "welcome1 " but all failed.
Why there are this difference between 11.2.0.1.0 and 11.2.0.3.0, and since in 11.2.0.3.0 the create sql are success, what password is correct when login?
