Glad you liked it,
That was a bit impatient of me - it's just the "give it to me" attitude that I get really irritated with.

It's a shame that I can't top Guy's answer. It is superb and gets to the point quickly and efficiently, when you have a question ask it politely.

I'm glad that you created three tables - it shows that you are a better carpenter than a coder. Perhaps you'd like to stay in that line.

You might want to consider just pushing them together. That's what we will be doing at Christmas to make room for everybody.

You need a basic SQL reference manual. Perhaps O'Reilly's SQL Cookbook[^] would help you.
I could post a sample query but I really don't think you'd understand it, and the time and space to explain it isn't suitable for this forum.

hi
i have a table that store applicant with their mark.
i want to get their grad in a query.
should i use a function and call for any applicant?
also if two applicant have same mark they must have same grade.

You need to decide whether the Grade is something an Applicant has, or not.
I suggest an Applicant has a Mark, and the Grade is calculated from the Mark. So your Applicant business object would have a Grade property that returns something based on the Mark.

|

thank.
you are right.
but in my database
how i calculate the grade.
i want to know if i can calculate all grade in one function or i must call a function instated of grade in my query so for each row the function is called again?
sepel

|

|

You could use a computed column on the table for a quick and easy database solution. Or you could just stick an extra property on your business objects.
The important thing to realise is that theres no real need to _store_ the Grade anywhere - because its easy to calculate.

thanks.i know your mean.
but how i calculate the grade?

Thats your algorithm, its really up to you. In Australia we say a High Distinction as above 85%, Distinction 75-85 etc etc.
You'll need to ask your client for this one.

I thought I'd post this, just in case anyone is struggling to get Entity Framework Beta 3 working in 64-Bit environments.
Microsoft's line is that the design time EF Beta 3 is not supported officially, yet, on x64 platforms. This leads to all manner of billy, including the csdl, msdl and ssdl mapping files not being generated.
The work around is incredibly simple:
Copy:
Microsoft.Data.Entity.Build.Tasks.dll
Microsoft.Data.Entity.targets
from %windir%\Microsoft.NET\Framework64\v3.5 to %windir\Microsoft.NET\Framework\v3.5
and then rebuild the project (F6).

Hi All,
I am using SSRS2005 to generate the report. I have used Date Picker control. Date picker is working at runtime when I run directly, i.e. http//server ip/reports.

Hi all,
I am facing a helllot of problems with views..
I created a view as
create view viewname as select * from tabel1;
but when i run an update query on the view , it updates it in the tabel1 tooooo
any help guys????

A view provides a way of looking at the data in a table or tables. A view holds no data in its own right, it simply represents a cached SQL SELECT statement that returns data from the underlying tables. A simple view like yours is updateable, because each row in the view can be mapped back to a row in the underlying table tabel1. This means that you can run insert/update/delete queries on the view as if it was a real table.
BTW, it's table, not tabel.

So how do i create a view such that the actual data is not altered.
I mean if i wan`t to test some queries on data. This is an ideal situation in online databases

I don't understand. How can you test an UPDATE query if you're not able to update any data?
In a typical software development setup, you would have a development environment that is separate from your production environment. Testing of code can be performed in the development environment without compromising the running of the production environment. Your development environment should replicate your production environment as closely as possible. This way, when you move your application from development to production it should behave predictably.

My understanding was that views are not updatable in Microsoft SQL Server, unless you use an INSTEAD OF trigger to perform the updates on the base table.
Please post the exact version of the exact database server software that you're using with your questions. It saves a lot of time.

This isn't the case. I was able to run an update query on a simple view. The MSDN documentation states:
INSERT, UPDATE, and DELETE statements must also meet certain qualifications before they can reference an updatable view. UPDATE and INSERT statements can reference a view only if the view is updatable and the UPDATE or INSERT statement is written so that it modifies data in only one of the base tables referenced in FROM clause of the view. A DELETE statement can reference only a view that is updatable; the view must also reference exactly one table in its FROM clause.
AFAIK, a view is updateable if it returns rows of data that can be directly mapped back to rows of data in the underlying table that contains the fields being updated.

Hi,

What do you mean by 'trim'? In programming terms, this usually refers to removing leading or trailing white space in a sequence of characters. In your example, you appear to be referring to the removal of insignificant digits from the string representation of a number. You also haven't stated which database system you are using. Is it SQL Server, Access, Oracle or something else? If you are trying to remove insignificant digits and are using SQL Server, you could write a function which uses the PATINDEX function to find the position of the first non-zero digit in the string and then uses the SUBSTRING function to return all digits at and after this position.

SELECT CAST(CAST('0001234' AS INT) AS VARCHAR(10))
Should also do the trick for you.

Is it possible to utilize the TransferText function from a database table in MS Access to a TextFile object? I need to be able to write three lines of code to a file and then transfer the records from the database table to the very same file utilizing the TransferText approach because the file needs to be presented in a certain way to the .CSV file. Is this possible?
I would appreciate any assistance you could provide. Here is the code so far:
Set fs = CreateObject("Scripting.FileSystemObject")
Set a = fs.CreateTextFile(strNewOutputString, True)
strDatePicker = dteDatePicker.Value
dteMonth = Month(strDatePicker)
a.WriteLine ("ACTUALC")
a.WriteLine (dteMonth & ",,")
a.WriteLine (dteMonth & ",,")
'Needs to be able to transfer the text in this format using the "Standard Output" specification format.
DoCmd.TransferText acExportDelim, "Standard Output", _
"tblExportCSV", strNewOutputString, False
a.Close

Hello,
I am trying to get Random records from MS Access by using following query,
SELECT * FROM myTable ORDER BY rnd(id)
where id is the autonumber primary key of type integer.
Now the problem is, I am always getting same records every time I run the query. How can I get different Random sequence different time ? Would anyone give me a query to take SEED from Current Time's Tick for Rnd function ?
Regards
