Suppression of zeros of a column
HelloI want to remove the zeros of a column of varchar type that allows to store alpha numeric characters.
Here's the scenario:
0-> 0
00-> 0
000-> 0
If I use ltrim(column,'0') it returns null
Thank you
Manoi.

Replace the empty column with ZERO values
Hi experts,
I'm building a report to display the number of orders per channel / day / hour.
Since a few days one or several channels may not all orders placed against them in which case my report shows empty values in the report.
Ideally, I would have zero in these columns rather than an empty cell.
Sample Qry: -.
Select
Channel,
Count (order_num) County
Of
SALES_ORDER
Pls help!
Thanks in advance.Count always returns 0 if no line found or the actual number based on the found rows. You don't even have to NVL them. I think so
the problem is in your report layout, in my opinion.You run query sqlplus, or Toad or sqldevloper and you can see for yourself that the count is 0.
See you soon.

Question newbie Oracle SQL adding columns to count the contents of the other columns
Greetings,
I do not understand how to integrate charges to my current SQL code that would consist of food and then the elements of the car for each person. Once I understood this concept I want to apply to my real data base (Oracle) where I count medication and problems for each patient.
Using my data of test below, for example the My goal would be to have the number of columns show that Cathy had County 3 foods and an element 1 cars (the County would need to ignore the values zero in these columns). I really don't like if the counter value is repeated in every row for that person.
Select data1. Name, data1. Category, Data1.Results,
Box When data1. IN category ("food") then end FOOD data1.results,
Box When data1. IN category ('Cars') then data1. Results end of CARS
Of
(
Select T1.name name, category null, null results in a_Main T1, a_Food T2 where T1.cpi_seq = T2. CPI_SEQ
UNION
Select T1.name, 'food', T2. Food a_Main T1, a_Food T2 where T1.cpi_seq = T2. CPI_SEQ
UNION
Select T1.name, 'cars', T3. Cars a_Main T1, a_Cars T3 where T1.cpi_seq = T3. CPI_SEQ
) data1
where data1. Category is not null
by name, category

cfspreadsheet how to keep the zeros
Is there a way to preserve the zeros in a field when viewing in excel other than adding a ' at the front of the field? I have a defined id in sql server as a varchar field, but what creating an xls document using cfspreadsheet excel interprets the numeric field and drop the zeros. I can't have the "leading this field because it is imported in another system."
This has been resolved. I tested the two proposed solutions. I tried to format the columns with spreadsheetformatcolumn as suggested by http://stackoverflow.com/questions/3081202/how-to-format-spreadsheet-c Columns-help-coldfusion , but which do not preserve the zeros in the column ID. I then tried the solution with POI found here http://www.bennadel.com/projects/poi-utility.htm by Ben Nadel and who did keep the zeros. Thanks for everyone's help and thanks to Ben for sharing his POI utility.

Is there a way to get the new value assigned to a column of series (DG4IFMX)
Hi people,
I need to insert records into a table whose primary key is a column of series (even as a trigger on a primary key in Oracle). I have been informed that the way to trigger the next value is to insert a zero in the column, which is fine. The problem is, that I need to know what the next value that has been assigned, and there is not enough time between the transaction to do a 'select max (column_name)', for example. Is there something (maybe a function) that responds to this need, and I don't know about it?
Thanks, any idea would be appreciated.
-Adam vonNiedaThe gateway offers the PASSTHROUGH - described in more detailed manual - package which allows you to send anything to the foreign database without being touched by Oracle.
Depending on your function, you can use the DBMS_HS_PASSTHROUGH. The EXECUTE_IMMEDIATE package and if you need to retrieve something that you could use:
dbms_hs_passthrough. Parse
DBMS_Hs_Passthrough.fetch_row
dbms_hs_passthrough.get_Value -

Please someone help me on the query.
I'm using oracle 11g. The column has many numbers. few are positive numbers, negative numbers are few, and few are zero.
the table structure is as this:
Col1
9
-5
3
60
10
-15
-45
0
87
Now, I have to count the number of positive, negative and all number the number zero of the column and display three columns like this:
Nega_value
Posi_value
Zero_value
3
5
1
What would the query?
Select sum (case when col1< 0="" then="" 1="" end)="">
sum (case when col1 > 0 then 1 end) posi_value,.
sum (case when col1 = 0 then 1 end) zero_value

SQL gurus
In the past you have helped me and I hope to take advantage of your knowledge again: I created a select depreciation that dampens the loans based on a table of loan information. The problem is this: when I run an ITERATION on the numbers, the select statement returns a value, but the ITERATION seems to be reading of zero. This leads to a lot of zeros in the resulting table.

Jones 0 131828.81 3,348 1 367, 8 - 132196,61 367.8 2023.55
As you can see, in the column C - B2, despite that references the C_USER12 column, which should have 2023.55 as a value in it, he's back the mirror in front of C_B1 which leads me to believe that the system reads a ZERO in the column despite the 2023.55 display.
I'm stumped, any ideas would be much appreciatedIf you put the CASE for C_USER12 statement in the ACTION clause instead of the select list, it should work. I think I came across an explanation in the documentation somewhere, but I'll have to go back and check.
The result would be
SELECT P, C_USER1, C_USER9, C_USER11, C_USER10, C_B1, C_B2, C_BUDGET, C_USER12 FROM MORTGAGE_FACTS MODEL PARTITION BY (C_USER1) DIMENSION BY (0 p) MEASURES (C_USER9, C_USER10, C_USER11 , CASE WHEN C_USER12 > 0 then C_USER12 ELSE ROUND( ( C_USER9 * (C_USER11/12/100)*Power((1+C_USER11/12/100), C_USER10)/(Power((1+C_USER11/12/100),C_USER10)-1)), 2) end C_USER12 , 0 C_B1, 0 C_B2, C_BUDGET) RULES SEQUENTIAL ORDER ITERATE(1000) UNTIL (ITERATION_NUMBER+1 = C_USER10[0]) ( C_BUDGET[0]=C_USER9[0], C_USER11[ITERATION_NUMBER+1]=C_USER11[0], C_USER9[ITERATION_NUMBER+1]=C_USER9[0], C_USER10[ITERATION_NUMBER+1]=C_USER10[0], C_USER12[ITERATION_NUMBER+1]=C_USER12[0], C_B1[ITERATION_NUMBER+1] = Round(C_BUDGET[CV()-1] * C_USER11[0]/1200,2), C_B2[ITERATION_NUMBER+1] = Round(C_USER12[CV()-1] - C_B1[CV()],2), C_BUDGET[ITERATION_NUMBER+1] = C_BUDGET[ITERATION_NUMBER]- C_B2[CV()] ) ORDER BY C_USER1, C_USER11, P
Another option is to wrap select another selection. i.e.
SELECT * FROM ( SELECT P, C_USER1, C_USER9, C_USER11, C_USER10, C_B1, C_B2, C_BUDGET, CASE WHEN C_USER12 > 0 then C_USER12 ELSE ROUND( ( C_USER9 * (C_USER11/12/100)*Power((1+C_USER11/12/100), C_USER10)/(Power((1+C_USER11/12/100),C_USER10)-1)), 2) end C_USER12 FROM MORTGAGE_FACTS ) MODEL ...

Report with multiple calculations
I learn the reports and the need of some inputs on how can I manipulate the following report
1. one of my region summarized in the report should show 5 amounts as a view table and the sixth column should be the sum of the first 4 columns (I get these 5 values with a query)
2. in the second row with an external condition is false, I need to put zeros under each column one ad the sixth also is zero
3. but if the condition is true, I need to calculate a new amount (multiply by %) and to show the title of each column that amount and again to add the new amounts in the sixth column
I don't know if I have to use forumla or place holders, please help me.

How to make the text object nullable?
I created a form of the Apex by using wizard.
It was a text element that wasn't a null column in the database. Now, I did the nullable column in the database.
However, in the form of the Apex, he still refuses to accept a value zero in this text element.
Where can I change in shape to make nullable?
ThanxHello
The wizard creates a validation non-zero for the column that was originally not a nullity. Check the validations and delete the entry.

Hello
Follow these steps in the expression of import on the amount column Format. Add NZP as an Expression of the import by clicking on the pencil next to the amount on the Import Format screen and then add NZP.

Select only records where the column values are not all equal to zero
Hi everyone, it seems so easy, but it has left me speechless on the research in a way that is clean, easy to achieve. I know when someone replies, I'm going to kick me. So, let's assume this is what I have:
I need an external application around it or something which will select only 'Type 1'... that is, if all months are each equal to zero, do not include the record in the result set.with mytable as ( select 'Type 1' as itemtype, 'JAN' as monthname, 0 as theval from dual union all select 'Type 1' as itemtype, 'FEB' as monthname, 1 as theval from dual union all select 'Type 1' as itemtype, 'MAR' as monthname, 5 as theval from dual union all select 'Type 1' as itemtype, 'APR' as monthname, 1 as theval from dual union all select 'Type 1' as itemtype, 'MAY' as monthname, 4 as theval from dual union all select 'Type 1' as itemtype, 'JUL' as monthname, 0 as theval from dual union all select 'Type 1' as itemtype, 'AUG' as monthname, 0 as theval from dual union all select 'Type 1' as itemtype, 'SEP' as monthname, 1 as theval from dual union all select 'Type 1' as itemtype, 'OCT' as monthname, 7 as theval from dual union all select 'Type 1' as itemtype, 'NOV' as monthname, 1 as theval from dual union all select 'Type 1' as itemtype, 'DEC' as monthname, 2 as theval from dual union all select 'Type 2' as itemtype, 'JAN' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'FEB' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'MAR' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'APR' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'MAY' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'OCT' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'NOV' as monthname, 0 as theval from dual union all select 'Type 2' as itemtype, 'DEC' as monthname, 0 as theval from dual ) select itemtype, sum (case monthname when 'JAN' then theval else 0 end) as JAN, sum (case monthname when 'FEB' then theval else 0 end) as FEB, sum (case monthname when 'MAR' then theval else 0 end) as MAR, sum (case monthname when 'APR' then theval else 0 end) as APR, sum (case monthname when 'MAY' then theval else 0 end) as MAY, sum (case monthname when 'JUN' then theval else 0 end) as JUN, sum (case monthname when 'JUL' then theval else 0 end) as JUL, sum (case monthname when 'AUG' then theval else 0 end) as AUG, sum (case monthname when 'SEP' then theval else 0 end) as SEP, sum (case monthname when 'OCT' then theval else 0 end) as OCT, sum (case monthname when 'NOV' then theval else 0 end) as NOV, sum (case monthname when 'DEC' then theval else 0 end) as DEC from mytable group by itemtype order by itemtype
In summary to get a total of zero is not an option, because I could have-15 and + 15 in different columns, in which case, the recording should be displayed.
Something as simple as... 'not the case (oct = 0 and 0 nov and dec = 0...) at the end is all it seems to me necessary. I thought to add a case for each column clause, but that seems not very effective. Ideas?
Thanks in advance!

Edit... I know not what follows will work using the MINUS operator, but my actual query is really huge, and I don't want to have to write it twice...

apr = 0 and may = 0 and = 0 jun and Jul = 0 and aug = 0 and Ms = 0
)
order of itemtype
{code}
Change again... OK, I guess that I am answering my own question here, but I think that by using a WITH to write the main request once clause and then selecting * twice using the MINUS operator between where the second query is where (oct = 0, etc.) is what I need. If anyone has better suggestions, please let me know! Here's the logic of nickname for what I come up with to date...
{code}
WITH mainquery as (select all)
Select * from mainquery
less
Select * from mainquery where (oct = 0, nov = 0, etc...)
{code}
Thanks again!

You can do it with a HAVING clause:
select itemtype, sum (case monthname when 'JAN' then theval else 0 end) as JAN, sum (case monthname when 'FEB' then theval else 0 end) as FEB, sum (case monthname when 'MAR' then theval else 0 end) as MAR, sum (case monthname when 'APR' then theval else 0 end) as APR, sum (case monthname when 'MAY' then theval else 0 end) as MAY, sum (case monthname when 'JUN' then theval else 0 end) as JUN, sum (case monthname when 'JUL' then theval else 0 end) as JUL, sum (case monthname when 'AUG' then theval else 0 end) as AUG, sum (case monthname when 'SEP' then theval else 0 end) as SEP, sum (case monthname when 'OCT' then theval else 0 end) as OCT, sum (case monthname when 'NOV' then theval else 0 end) as NOV, sum (case monthname when 'DEC' then theval else 0 end) as DEC from mytable group by itemtype HAVING MIN (theval) != 0 OR MAX (theval) != 0 order by itemtype ;
If the values are all 0, then the MIN and MAX will be 0.
If the MIN or MAX is not 0, the values are all 0.This assumes that the combination (itemtype, monthname) is unique, because it is in your sample data.
If this is not the case, start with a subquery that GROUPs BY itemtype, monthname, so that when you get to the main request, this combination will be unique.
