The first answer will work, but you might want to consider making this a lookup column linked to a table with a descriptive name for your codes - bit more maintainable.

what database are you using.
Look at OPENROWSET, I think that allows you to get at a file using select.

It could be that SQL Server Browser service is not running.

I am taking a class on Databases. As a project assignment I need to write about an 'important database subject (such as query optimization, database design, distributed databases)'. I was hoping someone would be willing to offer some other important database subjects that may not have received much attention. If you have a topic please share, no I am NOT asking anyone to provide any research or writing.
this thing looks like it was written by an epileptic ferret

There's nothing wrong with picking something like database design. You may want to look at database normalization, as well.

Hello, I've googled far and wide and this is one of those rare things I just can't seem to find an answer for. Hopefully it's easy, but this is my first time ever playing with SQL Server CE and the answer eludes me.
All I want to do is reset my AutoIncrement column back to 1 when I clear the table. DBCC CHECKIDENT apparently is not supported in CE and I can't find a way to do it. Can anyone help?
Thanks much.

Try ALTER TABLE command like following:
ALTER TABLE TableName ALTER COLUMN ColumnName IDENTITY(1,1)

That worked brilliantly. Thank you! I should've thought of that from the start.

select m_id from w_mat where ( w_mat.row_id in (Select prime_id from d_table where a_type=3 and o_type='XXX' and a_name='YYYY' and ( decode(REPLACE (TRANSLATE(TRIM(a_value),'-.0123456789', '000000000000'), '0', NULL), NULL,to_number(TRIM(a_value))) = 1 )) ) order by 1
If a_value encounters a non-numeric value, this query returns an error. Is there a way to modify the query to look for the particular value (i.e) 1 and ignore if it encounters any non-numeric value during the data fetch..
Regards,
Rane

You have several approaches to this, for example:
- use REGEXP_INSTR to find nonnumeric characters. Use this inside DECODE to make the decision if to convert or not
- create a small function which returns number. Inside this, use TO_NUMBER and catch the potential error and ignore it. In case of an error, return NULL (or whatever is desired)

CREATE OR REPLACE FUNCTION business_date (start_date DATE,
Days2Add NUMBER) RETURN DATE IS
Counter NATURAL := 0;
CurDate DATE := start_date;
DayNum POSITIVE;
SkipCntr NATURAL := 0;
BEGIN
WHILE Counter < Days2Add LOOP
CurDate := CurDate+1;
DayNum := TO_CHAR(CurDate, 'D');
IF DayNum BETWEEN 2 AND 6 THEN
Counter := Counter + 1;
ELSE
SkipCntr := SkipCntr + 1;
END IF;
END LOOP;
RETURN start_date + Counter + SkipCntr;
END business_date;

If you mean the usage it could be something like (or wherever you want to use it):
SELECT business_date(SYSDATE, 20) FROM DUAL

I have some question about design my database.
I want to design a database for a Advertisement web site.
there are some ads in my site such as:car,shirt,mobile,house,etc...
any ads saved by a member of site and belong to it.
any ads visited by some member .
any ads have it's property .for example car has model,color.mobile has weight,have cam,have tollbooths.
house has infrastructure ,stage and ....
in FUTURE many ads may add to my site with their specific properties.
i want know should i store all of my ads in my table or save them separately?

I would recommend you have a Member table and an Advertisement table on with a memberid field which is the member's id who uploaded the advert.
A VisitHistory table that contains the Advert id, member id and maybe datetime with foreign keys to the member and Advertisement tables.
A table with main categories like cars, mobiles, houses etc and then a table with subcategories with a parent id on it which will be the foreign key to the categories table that filters the subcategories for each category. That way you can have all these main categories with all their subcategories and easily add new ones if you want diffirent kinds of adds.
This is obviously high level without any indexes or anything but I hope you get the idea.
Hope this helps.

Use inheritance in your database, so you can add different subclasses of Advert later.
From our docs:
In this example, a ServiceProduct and a StockProduct table are defined. Both primary key columns
are also declared as foreign keys referencing the Product.Id column. These relationships guarantee
that for every ServiceProduct or StockProduct record there will be a corresponding Product record
with the same Id. Effectively these two tables inherit from the product table...

Hi,
I have the following query
SELECT iAccountID,iViolatorID,Count(iViolatorID) FROM tbTempQNotificationRequest (NOLOCK)
WHERE IsProcessed = 0 AND sdtStatusDate >= @sdtCurrentDate AND sdtStatusDate < @sdtCurrentDate + 1
GROUP BY iAccountID,vcGroupByValue,iViolatorID
Is it possible say when I group by the result set return
iAccount|iViolatorID|Count
1-------|1----------|3
2-------|2----------|5
I would like to have a fourth column say AccountNo and I want that it should contain comma seperated values of AccountNo against the group by columns.e.g.
iAccount|iViolatorID|Count|AcccountNo
1-------|1----------|3----|X12,X23,X34
2-------|2----------|5----|X45,X56,X65,X32,X98
I hope my question is clear and understandable

One way to do this is to create a function where you pass in an id that returns a comma seperated string of account numbers for that ID.
Then your query would look something like
SELECT iAccountID, iViolatorID, Count(iViolatorID), GetAccountNumbers(iViolatorID) AS AccountNos
FROM tbTempQNotificationRequest
This will slow down the query a bit but it'll work.
Hope this helps.

Hi,
Thanks for the answer. You know i could call a function but the thing is this query is a part of function being called from stored procedure. My scenario is complex and calling another function will effect the procedure performance further as currently procedure takes 5 seconds to execute. So I was looking for something if we could accomplish it through SQL. Though thanks anyways.
Regards,
