View With Variable Number Of Columns
Oct 21, 2011
I've created a stored procedure which creates itself a view (a MV to be honest); the instructions to create this m.view are dinamically built insinde my procedure, so each time i run it, based on the different input parameters, i've got a different result (my output m.view can have three colums the first time, or ten the next time) how can I read my output view to put the data into file? I've tried with "select * bulk collect into my_array from my_ output_ view"...after declaring "my_array" as a varying array with the max number of colums I could ever have...but nothing: if the array dimension doesn't match the number of columns that i've on my view, i.e. i receive "ora-00947 not enough values" error.
Is there a method to dimension dinamucally the array to store my data? Or should I change the code to fetch some other way the data i need to put to a file?

My goal is this:I have a table which is being updated/changed by lay people with certain types of values. Constraints are given to them, but they need not conform to them as they update the table in excel.Now, I want to validate this table every-time before I use it. i.e. implement a script which can be run to verify is all the values are in the right format for further usage.
I have a variable number of columns (i.e. users can add further columns as their requirements change).From columns 3 to 'n' (depending on table given) the values should be 'Yes' or 'No'. How do I check this for a variable number of columns in PL/SQL?

I want to add a variable number of new columns to an existing table temp (with column provided).
Example:
NewColumnNo = 4
-> the columns shall be named rate_1, rate_2, rate_3 and rate_4
-> the values shall be = Column / NewColumnNo
The result shall be like this:
create table temp_res (prodid integer, rate_1 number, rate_2 number, rate_3 number, rate_4 number);
insert into temp_res values(1, 0.25, 0.5, 0.75, 1);
insert into temp_res values(2, 0.25, 0.5, 0.75, 1);
insert into temp_res values(3, 0.25, 0.5, 0.75, 1);
insert into temp_res values(4, 0.25, 0.5, 0.75, 1);
insert into temp_res values(5, 0.25, 0.5, 0.75, 1);
insert into temp_res values(6, 0.25, 0.5, 0.75, 1);
insert into temp_res values(7, 0.25, 0.5, 0.75, 1);
insert into temp_res values(8, 0.25, 0.5, 0.75, 1);
insert into temp_res values(9, 0.25, 0.5, 0.75, 1);

I am trying to perform a dml operation(insert) to insert data into a table. I created a procedure in which a insert statement is generated. In another procedure I am trying to execute this auto generated statement using execute immediate. For that I created 2 variables . First one contain the insert statement and other one contain the list of columns. I m passing these strings to execute immediate like this
Execute Immediate(v_query) using(v_col_list)
after execution i m getting the following error
ORA-01008: not all variables bound
ORA-06512": at ' db_name.load_data' , line no 217
but when i tried it with list of column into using clause it is working like
Execute Immediate(v_query) using col1,col2,col3
I have more than 150 tables in the schema and i am creating a single procedure to load the data into base tables by using external tables. By passing the table name to procedure it generates the update and insert statements but i am getting error while executing the statements with dynamic sql.

i am working on the oracle 10g.currently i want to build one procedure,where i get a variable which contain character as well as number.my aim in the procedure is to replace all the character like ( a,b..z) in this variable with the number field.
example
suppose i have one variable say
var := 'MALT011000012345MTLCAST001SMT84'
now i want to replace each character say
A with value 23
B with value 56
L with value 99
9 i will get these value form another table).
i will have handle thousands of variable and they can start with any character and they contain character anywhere.

but some time it gives error
unable to insert record and if we see detail it shows
ORA-01036: illegal variable name/number
error.jpg is attached. if there is some problem, it should not pass any entry and if there is no problem then why it gives error of illegal variable?

the problem below:
I have a table AlertData below:
DeptIDMONTHCount
192010-041392
192010-051134
192010-061094
192010-071333
292010-042217
[Code]...
Within each DeptID group I need to calculate absolute change of 'Count' column between previous and current months and compare change value with threshold.
If ratio >= threshold N number of times I need to make a note of that event. Threshold = 0.1 N = 2 - alert needs to exceed threshold two consequtive times
Here is data processing algorithm:
1. Calculate change between month 2010-04 and 2010-05: abs((1134/1392 - 1))= 0.18;
2. check change value against threshold: 0.18 > 0.1
3. Threshold was exceeded, set alert_fired_cnt counter to = 1
4. Once alert fired it creates a baseline for comparison - I need to use Count from month 2010-04: We're now in month 2010-06: abs(1094 / 1392 - 1)=0.21
5. check change value against threshold: 0.21 > 0.1
6. Threshold was exceeded, increment alert_fired_cnt counter by 1 = 2
7. At this point alert exceede threshold two times, I need to set a alert_triggered flag = 1 and reset alert_fired_cnt = 0 for further calculations
8. We're in montn 2010-07: abs(1333/1294-1)=0.03
8. check change value against threshold: 0.03 < 0.1
9. Since threshold was not exceeded, keep alert_fired_cnt counter to = 0
Above algorithm needs to be run for all DeptID groups.
I load above data into an associative array and loop through elements. I am having trouble keeping computations within each DeptID group.

I have a column which holds the data in the below format.
Source Data :
>SNO_SDSDQ-8192-BN>SNO_54-99-24120-8192
>SNO_SDSDQ-8192-BN>SNO_54-99-24120-8192>SNO_54-90-16489-008G
>SNO_SDPMDB-008G-11>SNO_54-90-18008-008G>SNO_54-62-08791-008G>SNO_20-81-00327
>SNO_SDPMDB-008G-12>SNO_54-90-17830-008G>SNO_54-62-08598-008G>SNO_20-81-00327
[code]..
Problem Statement :
Split the above data into individual components and create columns / aliases dynamically.If the column is present then place the data under the created column.
Example 1) :
>SNO_SDSDQ-8192-BN>SNO_54-99-24120-8192
Result
Column Name : SKUCol_54-99
Data :SNO_SDSDQ-8192-BNSNO_54-99-24120-8192
Example 2)
>SNO_SDSDAA-002G-101-J>SNO_54-90-16002-002G>SNO_54-62-05781-002G>SNO_20-81-00135-5
Column Name : SKU54-90Col_54_62Col_20_81
Data :SNO_SDSDAA-002G-101-JSNO_54-90-16002-002GSNO_54-62-05781-002GSNO_20-81-00135-5
Column Name can be derieved from the components like SNO_54-62-05781-002G
i.e. SNO_54-62-05781-002G ==> SNO_-05781-002G
"54-62" will give the Col_Name
The First Column will always have data starting with
SNO_SD%
This column is constant and will be named as SKU.
I need this data to be placed in the same record / row but under different columns as per the data set.Basically, Can the data be split into multiple parts based on delimeters and the columns are created based on the unique data in the parts that form the data in the column.

In my requirement, I have many calculated columns needs to be modeled for the fact table, I am thing using a Materialized view for all computed columns and expose this MV for reporting tools. Using Materialized view as a fact table to query is a good approach?
Actual table columns
ART_NO, ART_PRICE, PROFITTable along with actual columns
ART_NO, ART_PRICE, ART_PRICE_LAST_YEAR, ART_PRICE_TRIM, ART_PRICE_EURO, PROFIT, PROFIT_LAST_YEAR, PROFIT_TRIM, PROFIT_EURO.

i had an issue last week with enabling and disabling a column in a tabular view. and i have it working now.... when the page loads i disable the column in the 25 rows being displayed.
the problem i now have is when i use the pagination to move through the rows the columns are all now enabled.
so what i am trying to do is this:
i have a tabular view showing 25 rows at a time. there is one column with a code and one with a description. when the code is changed, via a popup LOV, the description is changed based on the valus in a lookup table in the database.
i need the description column disabled, so the user cannot simply just type in the column. but when the page is submitted, the column needs to be enabled so i have modified the sumbit button to respond to a dynamic action which runs some enabling code then submits the page.
SO....
this all seems to be working except for when you use the pagination, the description column is all enabled.
is there a way of running some javascript when the pagination is refreshed? some better way of doing it?

if there is any inbuilt function or way to find a row in the table that is having value for maximum number of columns.
For example, the table A has 5 columns
(c1,c2,c3,c4,c5) and it has 3 records(r1,r2,r3)
and
r1 has values only for c1,c2
r2 has values only for c1,c2,c3,c4
r3 has values only for c1
so I should get the result as "r3 has values for 4 columns & it is not having value for column c5".

I need to write a dynamic SQL in PL SQL to query an unknown number of columns. Let me take a simple example query here:
SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS
If I have known the number of columns, e.g. querying two columns: "FIRST_NAME" and "LAST_NAME", I can write a DYNAMIC SQL based on the template in table 8-2 of URL....
DECLARE
stmt_str varchar2(200);
cur_hdl int;
rows_processed int;
FIRST_NAME varchar2(200);
LAST_NAME varchar2(200);
BEGIN
cur_hdl := dbms_sql.open_cursor; -- open cursor
stmt_str := 'SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS';
[code]....
However, if I wish to write a dynamical sql to query these two columns for a more general purpose (which should meet the requirement to query different number of columns, e.g. three columns, FIRST_NAME, LAST_NAME, BIRTHDAY instead of two columns FIRST_NAME and LAST_NAME). To do this I first try to query the same two columns but using a different method, following URL.....My code for the same query has error, and I cannot solve it.
DECLARE
stmt_str varchar2(200);
cur_hdl int;
rows_processed int;
l_columns dbms_sql.desc_tab;
l_dummy NUMBER;
l_value NUMBER;
[code]....

I am working on an application that pulls data from an Oracle view into Microsoft Excel (Oracle 11g, MS Excel 2003). It is an automated pivot table created through vba. The problem I'm having is that the decimal points from number columns are being truncated - they don't make it to the pivot table.
When I use the pivot table wizard and set the external data source using a SQL string (select * from view), the precision is not lost. When I create the pivot table automatically in vba, the precision is lost. The pivot table settings, regardless of how the data is brought in, shows the format of the number column as general. This tells me that Excel is trying to figure out what the data type is, and can't (not smart enough).
When looking at the description of the view, the data type is NUMBER (no precision). The table that it is pulling from has the precision set (NUMBER(11,3)). I have tried using the following, but it doesn't work:
select to_number(field_name, '99999999.999') field_name from view

SELECT a.co_nm, a.mnfst_nr, a.mnfst_qty,
a.mnfst_nr || ':' || a.mnfst_qty || ';' || b.mnfst_nr || ':'
|| b.mnfst_qty
FROM vw_acao_critical a JOIN vw_acao_critical b
ON a.co_nm = b.co_nm AND a.mnfst_nr = b.mnfst_nr
[code]......
What will be the case when I need to concatenate for more number of values.
like when co_nm has three bahs and manfst_nr and manfst_qty has 3 values for each for bah.and if three are having same_mnfst nr then I should use something dynamic.how to achieve this.
