How to maintain a counter column?

Hi All,
I am a novice with Oracle. Currently I have a problem which requires me to maintain a counter in an oracle column.
Following is my schema:
assetTable
1. ID
2. Name
3. Count
recordTable
1. ID
2. AssetID
For each insert in the recordTable, I want to update the 'Count' column in assetTable by 1 for the appropriate 'AssetID' which is the foreign key to the assetTable. There would be multiple clients trying to do insert into the recordTable, however the counter must be incremented for each insert reliably. Initially I thought I would be able to achieve this by writing a simple trigger. But I think that a trigger which does a simple read and update would not work as their are multiple clients writing simultaneously.
Please suggest a solution.
Thanks in advance.

create or replace view v_asset as
select a.id, a.name, count(r.id)
from assetTable a, recordTable r
where r.assetID = a.id
{code}<br /><br /><br /><br />Google database+normalization for why any other approach is <a href="http://catb.org/jargon/html/B/Bad-and-Wrong.html" title="Bad And Wrong">Bad And Wrong</a>

How to set Tile count column or count row?

How to set Tile count column or count row? If not can do, How
to adjust count row or count column?
Thx for all idea.

The Tile container's number of columns and rows is calculated
based on each child's width and height (or based on tileWidth and
tileHeight which you can set). If you need more control over the
layout, use Grid.

How to maintain counter in a for loop

Hi,
How do we track counter in a loop?Isn't it the way I implemented.? Please suggest.

Both loops have errors, if you try to do for(i=60;i<120;i++) you're only running 60 loops, not 120.
You should also disable the autoindexing on incoming arrays as you want some split array indexes (actually you can optimize it by extracting the constant a[30] before the 1st loop and the opposite on the 2nd. Now you're extracting 2 numbers from a 1D array instead of 1 from a 2D array ...
The number on the select/sum function should be integers, no need to calculate doubles.
The small array to sum it up is only max 170 numbers, it's ok although a sum in a shift register would be better.

Every time you BULK COLLECT into a collection type the value is overwirtten. So you need to try something like this.

Report with multiple COUNT columns with counts from same table

I am new to discoverer so I am a bit lost.
I am working to create a report to show usage data from the eBusiness Knowledge Base. I have the query written in SQL using subqueries that is in the format:
Solution Number | Soultion Title | Solution Views | Positive Feedback | Negative Feedback
12345 ___________ Title ________ 345 ____________ 98 _______________ 34
The 'Views', 'Positive' and 'Negative' entries are stored in the same table so i am doing a count where setid=setid and usedtype=VS, then counting where usedtype=PF and usedtype=NF
In discoverer I can get the solution number, title and ONE of the totals but I can't seem to figure out how to get a COUNT for three different things from the same table in columns on the same row.
When I go to edit sheet -> select items once I select the COUNT option for the UsedType column in the table CS_KB_SET_USED_HISTS I can't select it again. I also have found now way to add a column based on an entered query.
If anyone could help it would be much appreciated.
Thanks
Edited by: Toolman21 on Dec 2, 2010 2:17 PM
added ______ to correct spacing.

Hi,
You can separate the column by using a case or decode.
for example create 2 calculations:
case
when usedtype='PF'
then <you original column> --- the one contain them both
else 0
end
case
when usedtype='NF'
then <you original column> --- the one contain them both
else 0
end
after that you can create the count aggregation over those.

How to Maintain the Pricing Condition Records in CRM

Hi
I am new to the CRM
How to maintain the pricing condition records in crm for the particular condition type?
as we do in SD(VK11)
Thanks

Hi Binu,
First of all, you could maintain pricing conditions in the following places:
1. In General Condition Maintenance (GCM)
2. At the product maintenance level
3. At the 'Price agreement' tab of Contracts
4. As manual conditions during order processing at item level
Now, if you want to maintain conditions using GCM, you first have to maintain a condition maintenance group in the customizing where in you can assign condition table and condition type for different counter values. I am assuming that you have done this activity successfully.
When you run the transaction '/SAPCND/GCM', for application 'CRM', your condition maintenance group name and context 'GCM', you will be initially taken to a screen where in you'll have an item area which would be blank and then condition fields would be displayed in a tree on the left.
Here, select the field 'Condition type' and click on icon 'Select records'. You would get a dialog prompting you to enter condition type. Here you can specifiy the condition type for which you want to maintain/view condition records.
If no condition records are available, item area would be left blank. Here, you can choose a condition type using the standard F4 help. Depending on condition types that are assigned to condition maintenance group, different condition types would be displayed in the F4-help using which you can maintain condition records.
Hope this helps.

Pavithra

How to get the count of each minutes

Oracle 10 DB
Hi All
I using this query to get the count of records fetched by the concurrent program per min,
select count (distinct b.attribute2)
from oe_order_headers_all a,oe_order_lines_all b
where a.header_id=b.header_id
and b.flow_status_code ='AWAIT_QUINTIQ_BOOK'
and to_Char(b.last_update_date,'DD-MON-YYYY HH24:MI:SS') between '19-JAN-2011 02:00:01' AND
'19-JAN-2011 02:00:02'
This is used to get the count of records fetched at one mins
How to find the count of last 10 mins ie 1 mins count 2.00 to 2.10
Thanks & Regards
Srikkanth.M

Try this:
SELECT TRUNC(b.last_update_date, 'mi') time_mins, COUNT(DISTINCT b.attribute2)
FROM   oe_order_headers_all a,
       oe_order_lines_all b
WHERE a.header_id = b.header_id
AND    b.flow_status_code = 'AWAIT_QUINTIQ_BOOK'
AND    b.last_update_date >= to_date('19/01/2011 02:00:00', 'dd/mm/yyyy hh24:mi:ss')
AND    b.last_update_date < to_date('19/01/2011 02:10:00', 'dd/mm/yyyy hh24:mi:ss')
GROUP BY TRUNC(b.last_update_date, 'mi');I'm not sure why you're bothering with the join to the oe_order_headers_all table, since you're not referencing that in the where clause or the selected columns list. I think you could probably do away with it.
I've changed your code to take the last_update_date and truncate it to the minute level, and added that as a column, so you can see which count goes with which minute. Obviously, this has to be in the group by.
I've also changed your date comparisons so that you're actually comparing dates to dates, rather than strings to strings - why would you deliberately take information away from the optimizer? Oracle does not treat strings the same as dates, and forcing it to use strings rather than dates could lead you to have a vastly differing execution path, which will most likely be less performant.
Not to mention, coding like that leads you to assume that you can compare dates in strings without any problems, and that is just not the case. '19-FEB-2011' is counted as being earlier than '19-JAN-2008', as strings sort alphabetically.

How to change a 3 column template to a 2 column template?

I'm currently working on this website.
For this website, I designed a page and saved it as a template with the editable regions being the leftcolumn, middlecolumn and rightcolumn divs. I then created each page using that template.
If I wanted to change just the home page from a 3 column layout to a 2 column layout, what is the best way to do this? I know how to make a 2 column site, I just need help with how to "unlock" the template so I can modify the code.
Would I need to open my template file, save it as template2col (or something similar) and make the changes there, then create a new home page using that template and saving over the index file?
The only other way I can think of making changes like this would be to copy the code, paste into wordpad, remove the template coding and then paste back into Dreamweaver. I'm sure this is not the proper method so I thought I would ask those who know much more about working with templates than I do.
Thanks in advance for your advice

I suggested 1 template per layout because it's a practical approach that is simple enough for anyone to utilize. You don't need to be an expert with CSS. Also, this method can withstand any CSS layout you care to use -- even the DW starter pages.
While Murray's approach is sound it will require some careful pre-planning. Not all layouts are built the same way. Choosing the right framework and having the CSS skills to work with it are essential.
Use whichever methods fit your coding skills and those of the person(s) who will be maintaining this site.

How do I set the column content to automatic break lines

Hello Guys,
I have a problem with the column width and the column content of a standard report. Within the report are hugh entries which aren't interrupted by an space character. I set my column width to a special value by usingen "css style: display block; width: 300px;". Now the problem is that some of the column entries have a longer width than the column width is setted. So they overlock the entries of the column next to them.
My question is: How do I set the column content to automatic break lines after a certain count of characters?
After researching a couple of websites and discussion thread I found maybe a reference to the solution. I hope it help you to give me an answer.
COLUMN LAST_NAME FORMAT A4
regards
wderr

Wderr,
PDFs are another animal entirely. Try adjusting the width of the column under the Print Attributes tab of the report.
If that doesn't work you'll probably need to create custom XSL-FO layouts which, depending on the tools you have at your disposal, could take some time.

Dan

How to store multiple counts based on creation date

then again till 14/03/2015 is 1. I want to retrieve the count based on the dates rendered dynamically on X-axis that is from current date back to past 24 days. I tried to create two datasets with one storing the risks after being queried based on creation
date and closure date and retrieving the count from Graph Y values but it is returning me count 0.
Please help.

How to create Implicit Fact column ?and how to use it ?

Hi all,
How to create Implicit Fact column ?
and how to use it ?
Thanks in advance

When you create a request with only dimension columns, the Oracle BI engine has to choose a fact table to join the dimensions to each other. If you have multiple fact tables in your BMM layer, the Oracle BI engine will use the most economical fact table, depending on the number of dimensions of the fact table.
In some cases you do not want to use this fact table, but you want to force the Oracle BI engine to use the fact table you want.
In that case you should create a fact (or select an existing fact) of the fact table you want to use for the dimension only query. In the presentation catalog of the subject area you should select this fact as the implicit fact. This fact will always be used in the query, but it won't be visible in your report. An example of an implicit fact is the count of the primary key (id) of the fact table.

Hello,
If you are looking for file download or view count then event handler will not work. You need to enable the analytic report to your site. Once you enable it then you can see the report within a browser or you can also create custom webpart to show count
