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.

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.

Application Express :: Hyperlink Column With Link Parameters As Region Column Values
Apr 10, 2013On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.

Pivot Query In Oracle To Get Years From Column And Make Separate Column For Each

Reports & Discoverer :: Value In Table Column Based On Some Existing Column Value Automatically Without User Intervention
May 15, 2011i have two questions.
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.
Reports & Discoverer :: How To Make Name Of Column Appear As Many Times As Column On Page
Nov 21, 2010This is what i want to do:
I have a basic report looking like this:
<Column name>
value 1
value 2
value 3
.
.
.
value n
Since the column is small it can fit in a page more then one time. I know how to make it print more then once: i switch the repeating frame to print down and across and i modify the frame that contains it so the horizontal elasticity is variable.
After these changes my report looks like this:
<Column name>
value 1-----------------------value n+1-----------------------value m+1
value 2-----------------------value n+2-----------------------value m+2
value 3-----------------------value n+3-----------------------...
.------------------------------- .
.------------------------------- .

What i want is my report to look like this:
<Column name>-------<Column name>------------<Column name>

value 2-----------------------value n+2-----------------------value m+2
value 3-----------------------value n+3-----------------------...

Application Express :: Column Link Where Column Number Changes With Query
Feb 11, 2013We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report
<code>select * from(
select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site,
case when count(*) < 31 then '*' else
round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct
from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b
where Overall_Satisfaction is not null and year_dt = 2012
[Code]....
The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.
Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)
ie
Overall Satisfaction JAN FEB MAR APR MAY ...
Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
etc.
So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.
Application Express :: Can Pass More Than 3 Column Values With A Column Link
Jun 19, 2012I want to pass multiple column values of a row in an interactive report page to hidden items in another page through column link. And I did it successfully. However, I found I need to pass more than 3 columns of a row in this report, while a column link only permits me to pass 3 column value at most. Is there anyway that I can pass more column values to hidden items in another page?

PL/SQL :: Bitmap Index On Number Column X Char Column?
Jul 23, 2013is there some performance/access difference between a bitmap index on a number column and char(1) column? Both columns are not null with a default value.My application has a querie like this:
select ass.column20, ass.column30from table_a pucinner join table_b asson ass.column1 = puc.column1where pc.column_char = 'S'and ass.column_char02 = 'P'
If I create a bitmap index on column "column_char", the access plan is not changed. But changing the column datatype to number(1) and obviously the values, the index is accessed and the cost decreases.This table has 4.000.000 rows. Oracle 11.2.0.2SO
