Can Rewrite Following Query Without Using Row_number() Function
Jan 13, 2011can I rewrite the following query without using the 'ROW_NUMBER() OVER ' part.The query is supposed to pull out the records whose CODE is not NULL and has most recent date for UPDATE_DATE . The reason I wanted to do this is, When I embed this query in between many other queries along with JOINs, My oracle server is unable to execute. So, I thought its better to supplant 'ROW_NUMBER() OVER ' logic with something else and try it. .
CURRENT QUERY:
SELECT a.* FROM
(SELECT b.*, ROW_NUMBER() OVER (PARTITION BY b.PIDM
ORDER BY b.UPDATE_DATE DESC) AS Rno
FROM
(
SELECT *
FROM SHYNCRO WHERE CODE IS NOT NULL
)b
)a
WHERE a.Rno = 1

SQL & PL/SQL :: Function Returning Top Value If Not Exists Then Next One?
Nov 20, 2010how 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.

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'?
SQL & PL/SQL :: Difference Between IN And EXISTS Operator

View 1 Replies View RelatedInsert If Not Exists Else Update
Aug 10, 2007I 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).

View 10 Replies View RelatedSQL & PL/SQL :: Replace Not In / Not Exists With Outer Join
Aug 30, 2010I have a basic requirement to report rows from one table where the second table do not have the same record (basically same key).I understand that we could achieve this using not in or not exists clause. But I think using outer join probably be the simplest one. However, I could not achieve what I actually wanted using outer join
Test Case:
create table tab_1 (a number(1), b varchar2(20));
insert into tab_1 values (1,'one');
insert into tab_1 values (2,'two');
insert into tab_1 values (3,'three');
create table tab_2 (a number(1), b varchar2(20));
insert into tab_2 values (1,'one');
insert into tab_2 values (2,'two');
commit;
Now, I framed the query as
select y.a ya, x.a xa, x.b xb
from tab_1 x, tab_2 y
where x.a = y.a (+);
/
YA XA XB
---- ---- ----
1 1 one
2 2 two
3 three
In this case, as there is no corresponding record in second table, the value of YA is showing as null as shown above.Hence, I changed the query as
select y.a ya, x.a xa, x.b xb
from tab_1 x, tab_2 y
where x.a = y.a (+)
and y.a(+) is null;
/
YA XA XB
---- ---- ----
1 one
2 two
3 three
I dont understand why it is behaving in that way. I am rather expecting the output to come as:
YA XA XB
---- ---- ----
3 three

SQL & PL/SQL :: How To Retrieve Data That Does Not Exists In A Table
Dec 13, 2011I have the following table with the some sample data:
|| Filename || receiving_site || originating_site ||
| fileA | siteA | HQ |
| fileA | siteA | siteA |
| fileB | siteA | HQ |
| fileA | siteB | HQ |
| fileA | siteB | siteB |
| fileB | siteB | HQ |
| fileB | siteB | siteB |
The table works in such way:
1. For each of the Filename, if originating_site is not the same as receiving_site, it means that the file has been sent to receiving_site but has not been acknowledged received yet.
2. For each of the Filename, if originating_site is the same as receiving_site, it means the file has been sent and received by the receiving_site.
My task is to list out all the Filename per receiving_site that has been sent, but not received yet by the receiving_site. For example from the sample data above, I am expecting to see that siteA, fileB has not been received yet.
How can I do that? I had tried MINUS and NOT EXISTS command, but I am just not able to get the result that I want.
