Find Nth Highest Salary?
Jul 18, 2011How 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);
Select Row With Highest Version
Aug 25, 2010My 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.
SQL & PL/SQL :: Getting Highest Value From Varchar Column
Feb 12, 2011I'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.

SQL & PL/SQL :: Grouping List Of Elements With One Or More Common?
Oct 6, 2011I have a one column table that store lists of elements :
create table test_table (c1 VARCHAR2(4000));
insert into test_table values ('1,23');
insert into test_table values ('1,2');
insert into test_table values ('3,4,5');
[code]...
The output column would be something like that:
output_column
1,2,7,23
6,9,0
3,4,5
I'm grouping columns that have at least one element in common.
(1,23) and (1,2) merge into : (1,2,23)
(1,2,23) and (7,2) merge into : (1,2,7,23) --> Output
(6,9) and (9,0) merge into : (6,9,0) --> Output
(3,4,5) and (5,5) merge into : (3,5,5) --> Output
I have made this logic using only PL/SQL, with loops and nested tables using function memberof, but I suppose that there is a way to improve the performance using only SQL.

Application Express :: How To Validate In Common PL/SQL Package And Show Custom Messages
Feb 11, 2013Currently if i let required field empty, then APEX puts systematic error message "XXX must have some value." near the field and into the page header. I want to create custom business rule, that would show message for example "This action cannot be performed, because this and that...".
That kind of custom validation should be in my plSql package and somehow it should throw/send the phrase "This action cannot be performed, because this and that..." to the page header where was message "XXX must have some value.".
How can i create such custom error message to appear out using PlSql package function that i define myself? I plan to create a common validation package, which has lots of plsql functions to validate lot of APEX pages/forms, all those functions should throw/send somehow error messages to page header. I looked that this unofficial solution does not suit for me:
[URL].......
Because it disables APEX systematic automatic validations as i understand, and is unofficial.
