Forming Matrix Of Data Using PL/SQL
May 15, 2013
I've got a requirement for building a 5000 X 5000 matrix using PL/SQL. My original data tables have 5000 rows each and I need to do a correlation analysis using this data and need to store in a physical table and not in-memory. Is this feat achievable using mere PL/SQL? I understand that Oracle DB has a limitation of 1000 columns(but not sure) and hence I'd like to know whether there is any work-around for such scenarios. If not, what are the other alternative method(s) to achieve this feat? Do I need to use any 3rd party tools to get this done?

we use oracle 11g. 11.2. I have a situation where in a pl-sql package, there is a modification needs to be done . Every User is associated with destination codes. For eg, user1==>0101,0104 There is a destination_number and country field in the table1.Each of the destination number is associated with a country code and this combination is unique. for eg:
dest_code country_code 0101 CHINA 0202 UK 0101 Mexico 0104 Mexico
For example, if user1 logs in to the system, then pl sql logic will look if that dest_code is in a table1,If the dest_code is present in the table1, then that dest_code number wont be added to the dest_code list formed for that user. For example,if user1 got dest_codes 0101,0104 associated with him.IF 0101 is in exception table then 0101 and 0104wont be used to form dest_code list. If NOT, a dest_code list will formed like 0101||0104. I am able to form the logic like I have a cursor that loops for each dest_code.For each dest_code , it will get that dest_code into v_dest_code_no number type variable. open cursor fetch dest_code no into v_dest_code v_dummy number:=0;v_dest_code_list number:=0; LOOP v_dest_code_list:=v_dest_code ||v_dest_code ; v_dest_code :=0; END LOOP: How to make sure that for each dest_code set, if one of them is in table1, then the next number also will not be added to the list.

Writing a query based on this data:
Each row is based on a row of a student.
Grade stands for the school grade, K=> Kindergarten
Tabl is a table the student is assigned to.
Bev stands for beverage, 1c=> White Milk , 2c=> Chocolate Milk, 3c => Orange Juice.
GRADE TABL BEV
K 1 1c
K 2 3c
K 3 1c
K 4 3c
K 1 1c
K 2 2c
K 3 3c
I need to generate a summary report that looks like this:
Grade/Tabl White Chocolate Orange
K-1 2
K-2 1 1
K-3 1 1
K4 1
Is there a way in which I can write a query to display this type of matrix report.

I am essentially trying to reproduce an extremely complex spread-sheet with an engineering mathematical model in it and that has been in use for 5 years now. The Excel spreadsheet was a good environment for tuning the model, but now I have been asked to design an Oracle Form that incorporates their mathematical model and shows their final and intermediate data so they can validate my app against their proven spreadsheet.
To do that I have to create a matrix style table for use as a child data-block in my Oracle Form.

I have a matrix report that shows production per year(horizontal) and per country(vertical). The customer's willing to see the data ordered by production, and not per country. I tried to add a CF containing the production in the country group and order by that one, but I'm getting a message saying that the field object cannot be contained into the frame. Both the field and the containing frame are set to Variable. how to get rid of the error or how to achieve the main goal of ordering by the cell content?
