PL/SQL :: Any Way To Get Rank Of Students Without Using RANK Function?
Mar 24, 2013I created a sample table named as "Student" with following data. table contains two columns only - stdid & marks.
stdid marks
10 75
20 60
30 60
40 45
50 30
I have to find the rank of students based on their marks in descending order.Is there a way to get rank without using RANK function?
SQL & PL/SQL :: Way When Doing Rank Function In PL/SQL To Pass Field
Jul 13, 2011there is a way when doing the Rank Function in PL/SQL to pass the field that will be ranked as an override.
SELECT rank(p_ColumnAmt) within group (order by p_ColumnNm desc) rank
INTO v_RnkNoAmt
FROM Table_name
WHERE ??????;
p_Column is the amount I am ranking
p_ColumnNm is the actual field name to Rank.
When I pass the field name with an override I do not get the correct rank back. If I run the Select with the actual field name curr_1_mth_amt, I get the correct rank.
I have about 70 different field to Rank and do not want to make a procedure for each field.
PL/SQL :: Rank Function And Duplicate Records
Aug 30, 2012I have the following table :
CREATE TABLE A_TEST (A INTEGER, B INTEGER, C INTEGER, D INTEGER, FLAG CHAR(11));
INSERT INTO A_TEST (A,B,C,D) VALUES(1,2,3,4);
INSERT INTO A_TEST (A,B,C,D) VALUES(2,4,5,8);
INSERT INTO A_TEST (A,B,C,D) VALUES(1,2,3,4);
INSERT INTO A_TEST (A,B,C,D) VALUES(2,4,5,8);
[code].......
I would like to perform an update on the FLAG column by setting to "D" if it is a duplicate record.1,2,3,4);
I would like to use the rank function.
Desired update:
A B C D FLAG
1 2 3 4
2 4 5 8
1 2 3 4 D
2 4 5 8 D
7 2 3 4
9 2 3 4

Apr 15, 2010i have a project that needs to have a identity number in the table.this is the table:
create global temporary table BOOK_INFO
( row_id number(5),
BOOK_TITLE char(20),
BOOK_AUTHOR char(15)
) on commit preserve rows;
i dont know how can i generate row_id, in sybase i can only set the datatype of row_id in IDENTITY and it will automatically generates number and as the transaction ended the row_id will automatically back to 1.
in oracle i tried to create sequence but it didnt back to 1 when the transaction/procedure ended.. Like for example if the procedure ended and the last row_id inserted in the table is 300 the next run of the procedure will start in 301. but i need to start in 1 in every run of the procedure.
Also, i tried to set the variable v_row_id to 0 and it increment by 1 as it insert in the table, but the problem is there are times that in 1 book_title there is more than 1 author. so the v_row_id of the book_title with more than 1 author is all the same.Here is my query:
insert into BOOK_INFO
(select v_row_id, BOOK_TITLE, BOOK_AUTHOR from LIBRARY);
The result is:
ROW_ID BOOK_TITLE BOOK_AUTHOR
1 BOOK_1 AUTHOR_1
1 BOOK_1 AUTHOR_2
1 BOOK_1 AUTHOR_3
1 BOOK_1 AUTHOR_4
2 BOOK_2 AUTHOR_5
SQL & PL/SQL :: Create A Function Which Can Be Used In A Select Query?
Jun 11, 2008I have a table structure like :-
Create table test(A varchar2(50),B NUMBER);
The data in that table is like that:-
A B
----------------------
2*3
2*4*5
4*5
column B contain no data.
I want to create a function which can be used in a select query,and the output should come like that :-
A B
----------------------
2*3 6
2*4*5 40
4*5 20
Means column B contains the resultant value of column A.And the above output should come through a select statement.You can use any function inside the select statement.

Jul 20, 2010I certainly know this is possibly but I am trying to do this on the fly and can't seem to work it out:
I have a table A:
ID Name Priority
-------------------
1 Smith 1
1 SSmith 2
1 ASmith 3
1 BSmith 3
2 John 2
3 Ed 1
and I am looking to create the following table from this:
ID Name Sum(Top3Priority)
--------------------------------
1 Smith,SSmith,etc 8
Now, I've got listagg working and everything appears to be going swimmingly but: for every listagg grouping on name I need to only sum the highest top 3 priorities. So in the example above there are four Smiths but I need to only sum the top 3 priorities which are 3,3,2 and ignore the 1 even though I do want all the listagg Smith's (SSmiht, ASmith, etc) in there.
Now I can sum the priority, but don't really know how to sum only the top 3 in any ID ? There can be 1 to n ID's so if there are only 2 ID's I want to sum those 2, if there are 3 all 3 and 4 upwards only the top 3.Here is a snippet of the SQL I am using
SLECT id,
listagg(MN_CR_LOOKUP.f_name, ',') within group (order by Priority)) roadname,

PL/SQL :: Using Lag And Rank In The Same Query
Mar 10, 2013I am trying to find out the difference in time between peoples memberships and also the order that these memberships are taken out in. So far I have added in a rank statement to work out the order the memberships were created in, but now want to look at the difference between the dates returned. The SQL I used is:
SELECT owner_party_id,
mem_number,
support_id,
mem_start_date,
RANK() OVER (PARTITION BY owner_party_id ORDER BY mem_start_date ASC) MEMBERSHIP_SEQUENCE
FROM membership_all
WHERE version_type = 'CUR'
AND owner_party_id IN ('65051', '65051', '65348', '65348', '65607', '65607', '65607')
to get:
"OWNER_PARTY_ID"|"MEM_NUMBER"|"SUPPORT_ID"|"MEM_START_DATE"|"MEMBERSHIP_SEQUENCE"
65051|318874751|8014747|01-MAR-10|1
65051|412311060|21502883|15-AUG-12|2
65348|308672459|3526913|01-MAY-10|1
65348|409951130|20950524|18-JUN-12|2
65607|315830192|7510133|17-MAY-10|1

65607|409738130|20903556|14-JUN-12|3
Now I would like to calculate the difference between the start dates of each of the owner_party_id groups, so to get something like this:
OWNER_PARTY_ID|MEM_NUMBER |SUPPORT_ID|MEM_START_DATE |MEMBERSHIP_SEQUENCE|Diff
65051|318874751|8014747|01-Mar-10|1|
65051|412311060|21502883|15-Aug-12|2|898
65348|308672459|3526913|01-May-10|1
65348|409951130|20950524|18-Jun-12|2|779
65607|315830192|7510133|17-May-10|1
65607|406448110|20024246|16-Mar-12|2|669
65607|409738130|20903556|14-Jun-12|3|90
I think that I need to use the Lag function in, but I am not too sure if it can be linked to look at the data within a grouping of owner party id, as it would make no sense to calculate the difference in dates for two different owner party ids.
Create A Function And Call It In Anonymous Block
Oct 22, 2013I made this script but I still don't quite understand if the syntax is correct. I just wanted to create a function and call it in an anonymous block. I then wanted it to use a variable as a parameter in an iteration and output the variable every iteration. It's done basically but I know it's not 100% right. The fibonacci function looks like its going to loop an infinite number of times if the parameter is greater than 2.

Apr 4, 2010When i try to execute a query, which is organised as the below example, it retrieves data..
select * from (
select col1, col2, col3, col4....coln
from TABLE_ONE left outer join TABLE_TWO
-- some conditions and group by clause
order by 1 asc
)
where rownum <=1000;
Again if I use Column alias in the ORDER BY clause col1, the query won't retrieve data.
Also If I use ORDER BY 4 instead of ORDER BY 1, the query wont return data...
select * from (
select col1, col2, col3, col4....coln
from TABLE_ONE left outer join TABLE_TWO
-- some conditions and group by clause
order by 4 asc

where rownum <=1000;
The whole issue revolves around the inner ORDER BY Clause and external ROWNUM condition..If I eliminate any of the two, the query works fine...I am not sure if indexes have some role to play in it...
PL/SQL :: Cast Rownum To Number (10)
Jan 25, 2013I'm on Oracle Database 10g Enterprise Edition Release 10.2.0.4.0
I am working on a project where have lots of view on a different schema. For performance reasons, we create tables on those views and index them.
The application that uses these tables requires a numeric primary key of a specific length, e.g. number(10). Not all tables have a natural key that matches this requirement, so I added a rownum to the query. I had hoped that casting the rownum to a number(10) would result in the same datatype once the table is created.
e.g.
SQL> create or replace view rownum_to_number10_vw as
2 select cast(rownum as number(10)) objectid, dummy from dual;
View created
SQL> describe rownum_to_number10_vw;
Name Type Nullable Default Comments
-------- ---------------- -------- ------- --------
OBJECTID NUMBER(10) Y
DUMMY VARCHAR2(1 BYTE) Y
SQL> perfect! Now create a table based on this view:
SQL> create table rownum_to_number10_tb as 2 select * from rownum_to_number10_vw;
Table created
SQL> describe rownum_to_number10_tb;
Name Type Nullable Default Comments
-------- ---------------- -------- ------- --------
OBJECTID NUMBER Y
DUMMY VARCHAR2(1 BYTE) Y Oracle does not pick up on the number(10) cast!
How can I force Oracle to create a column with the same datetype as the underlying query?
ps:I know that the 10 in number(10) is more like a constraint than a datatype, but the application that uses this table will create an additional column if the datatype > 10. I want to prevent that from happening...

Create A Function Based Index On Bold Highlighted
Jul 2, 2010Using oracle 10g R2 on sun-solaris 10 (sparc-64) Well in the MIS system we have lot of ad-hoc queries coming up. We have proper indexing. Say an example which runs very slow;

Execute Create Procedure / Function From SQL Script In SQLPlus
Feb 17, 2010I have a series of SQL scripts which contain SQL statements to create tables, populate them, create functions and stored procedures. Now I would like to execute each sql file against SQLPlus using a batch file so that I can just run this one file and all the configuration work I need to do can get done.
Problem is, when I try to execute the SQL file against SQLPlus, it gets upset with the Create Procedure/Function scripts...
I am using the following command:
sqlplus u/p@<someserver> @<path_to_sqlfile>.sql
this sql file contains create procedure pl/sql code
Is it possible create/compile SP/Functions that are contained within SQL Files using SQLPLus? Or do I have to physically write them out in SQLPLus (or load them in SQLDeveloper) to accomplish this?
