I need to get the highest value among these. how to get it?
How does the following underlined query works to find the nth highest salary
SELECT DISTINCT(A.SALARY) FROM EMPLOYEE A
WHERE &SALARY = (SELECT COUNT(DISTINCT(B.SALARY)) FROM EMPLOYEE B
WHERE A.SALARY<=B.SALARY);
My table holds info on documents:
|doc_id|auth|version|date_created|
so what I'm trying to do is select the latest version of each document record.
so say I have there records:
doc_uid|doc_id|auth|version|date_created|
|1 | 100 |al |0.1 |11/4/08 |
|1 | 101 |al |0.2 |11/4/08 |
|2 | 102 |al |0.4 |11/4/08 |
So i want to select only one copy of every doc_uid(unique id) with the highest version number, which would make my output:
doc_uid|doc_id|auth|version|date_created|
|1 | 101 |al |0.2 |11/4/08 |
|2 | 102 |al |0.4 |11/4/08 |
doc_id 100 was excluded because it has a higher version which was shown instead.
So how would i express this is oracle sql.
edit: Just thought i should say that I have been tring to crack this for 2 days now :P I have been messing around with MAX() but I cant make it do what i want.
I've a large table on which I applying aggregate and group by functions to the the results.
Here are two of the columns in my table:
Name ==== Score
John ==== 200*
Zohaib ==== 299
Ali ==== 0*
John ==== 200
Maria ==== 150*
Ali ==== 0
Maria ==== absent
John ==== absent
Here astrick (*) means with distinction....
The "score" column is a varchar column I want to run a query on this table to show the highest score for each student and the output should be like this:
Name ==== Score
Zohaib ==== 299
John ==== 200*
Maria ==== 150*
Ali ==== 0*
Important note:
1. if there is a tie between two highest scores like for a student, incase of john 200 was made twice, but the score with asterick (*) will be the "maximum" becuase it is with distinction so the output should also show the the highest score with asterick.
2. the output should show the the 2nd column (score) in desc order of highest score by each student...again incase of a tie, the one with astrick will come first in the result..
I know with just mere numbers, that is pretty easy but in this case it is a varchar column and also i need the astrick along with the highest score.
I want the simplest and shortest query if possible to achieve this result
I hope I've been able to clearly explain my requirment. I am using 10G.
how to find the nth highest salary
View 11 Replies View RelatedIs there any function avaialble in SQL that can return the highest common factor among a bunch of numbers. For example
10,20,25 have a highest common factor of 5.
i was given a task to find the second highest employee sal from emp table.
View 5 Replies View Relatedgo through both the given queries...
SELECT * FROM EMP A WHERE 1=(SELECT COUNT(DISTINCT(SAL)) FROM EMP B WHERE B.SAL>A.SAL);
SELECT * FROM EMP WHERE SAL=(SELECT MIN(SAL) FROM (SELECT DISTINCT(SAL) FROM EMP ORDER BY SAL DESC) WHERE ROWNUM<=2);
both queries will fetch second highest sal from emp table.which sorting is used by oracle in order by and group by clause.
I am trying to update the security_level of a mission to the highest security level of missions of the same type.
Attributes of the missions table:
mission_id, code_name, mission_type_id, mission_date, security_level
The following is an intermediate output.
MISSION_ID MISSION_TYPE_ID SECURITY_LEVEL
318 3 6
329 3 2
286 5 6
521 5 3
281 6 4
396 7 3
331 8 4
14 9 4
230 9 0
486 10 2
The maximum output for each mission_type_id
MAX_LEVEL TYPE
6 3
6 5
4 6
3 7
4 8
4 9
2 10
According to this 3 records (329,521 and 230) should update.
But my code returns an error.
ERROR at line 4:
cannot update (......"SECURITY_LEVEL") to NULL
this is my code
UPDATE
AM_X_442_2 amx
SET
Amx.SECURITY_LEVEL =
(
select
max_level
[code].........
I have intended the query to make it legible but it removes all spaces.
I want to Bold the value with highest value in Numeric field. how can i do this.
