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?
View 4 RepliesI 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!
What is the fundamental difference between MINUS keyword and LEFT outer join in Oracle.
I can achieve same results using either one of them.
what the difference between IN and EXISTS operator. Why should we use EXISTS operator?

I have below query which uses between clause. For some constraints I cannot use between clause so this need this to converted to use only relational operator.
select * from TABLE1
where "+ width +" between start_width " + "and end_width and "+ height +" between start_height " + "and end_height " + "and id = "+ id
I wrote an query and regarding one part, i have syntax problem, when should we seperate different arithmetic operators in a query?
for example
select density_with_desert.popp / density_with_desert.arr - sum(darea) from counytyi don't want to use variables.
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

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?

How do i optimize it best?
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,

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 *

'XXX0362',
'XXX0363',
'XXX0343',
'XXX0342',
'XXX0499',

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?
I have a question i wanted to know that " Is it possible to write the Following Query Using NOT EXISTS

how to write a function that returns top value if not exists then next top for combination of customer_id and hierarchy.For instance :
If I've got table
customer_id ,hierarchy, function_code
123 |1 | Z1
123 |2 |67
123 |3 |5B
678 |10 |S2
678 |11 |Z2
345 |2 |11
For the customer ID 123 I want to return Z1, for customer 678 I want to return S2 and for customer ID 345 I want 11
Problem is that I'm new to the concept of looping. I know how to write a function that accepts customer_id as a value write a cursor and then check IF hierarchy = 1 the return FUNCTION_CODE IF hierarchy - 2 THEN ...
but I need something more universal as some of the customers may have hierarchy function 1 and that would be the top one for him but others might have function of hierarchy 10 as top and checking all of the possibilities using if would be just stupid. So how to write something universal ? And of course if function did not find any customer_id then return null.

i have also another concern as per below xml file.
My requirement is to identify perticular node ,whose having PriorValue attribute present in <pi:the Actual_Comp_Change> tag,those record should return.

1000 roy Intern - Master¿s 00 266000
But my requirement is to display only those employeeID ,where Actual_Comp_Change tag having PriorValue attribute.
The required OutPUT should be :

is there any possibility to use ExistNode() function to the above quer or is there any alternative solution.
I have this sample:
the column data1 is datetime datatype with
t as ( select 'SMITH' nom,to_date('21/09/2013 07:30:00') data1
from dual union all select 'ALLEN',to_date('21/09/2013 07:40:00')
from dual union all -- select 'WARD',to_date('21/09/2013 07:50:00')
from dual union all
select 'JONES',to_date('21/09/2013 08:00:00')
from dual union all
[Code]..
How can I write a select to check that If I input 10 minutes to nom 'ALLEN' it's ok because the time 07:40 + 10 minutes = 07:50 the row not exists, (the next)but If input 20 it exists because the sum = 08:00 and row isn't free , indeed, there is 'JONES'?
I have a single table with a TOTAL_TIME column which I want to increment by a certain amount every time I get a request from a specific user. If the row for that user does not exist, it should be created and the TOTAL_TIME column should be set to the value that just came in. Otherwise, if it does exist, it should be incremented by the value passed in.
How can I accomplish this in oracle? I don't want to just first do a select, then insert, because that can cause race conditions. I want something that'll do the check and insert/update in one statement (locked).

I am facing a problem in my database that whenever I load any kind of database objects in a particular tablespace then it gives:-

If I load in any other tablespace, everything works fine. I am getting error while export/import, create a table etc. How can I resolve it. I was wondering that may be it is facing problem while writing to a particular datafile.
