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

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.

oh... sorry it was a typo.
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.

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

All,
I have been toying with this query for some time now to no avail. I need to run a retention report on sales that canceled within 30, 60, 90 days of the original sale date. My query is below. Could someone please help me in the right direction as to why it doesn't work? The error I get is below the query
<br />
SELECT count(*) FROM db.orders<br />
where date_entered between "2007-08-01" and "2007-08-31" and cancel_date <= date_add('day', 30, date_entered)<br />
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '30, date_entered)' at line 2
Thank you very much!

Reference for DATE_ADD in MySQL 6.0[^].
I think the correct syntax would be DATE_ADD(date_entered, INTERVAL 30 DAY).
MySQL is not SQL Server and they do not necessarily use the same syntax for features that both implement. There is a common but very limited standard SQL syntax; many databases support most of SQL-92, but usually not all of it.

Thank you so much! That finally got it working. I knew there was a difference in mysql, but I just couldn't figure it out. Usually its the simple things that fix these problems. Thanks again mate!

Hi all. I'm getting a strange error against an Oracle 9i database. I have a stored proc and one of the cursors I'm using has the following SELECT;
<br />
SELECT ref_no_rev, ref_no FROM<br />
(<br />
SELECT REVERSE(ref_no) AS ref_no_rev, ref_no<br />
FROM (<br />
SELECT DISTINCT ref_no<br />
FROM itm_table<br />
WHERE ref_no IS NOT NULL)<br />
)<br />
ORDER BY <br />
ref_no_rev<br />
And when I execute it directly against the database from the TOAD editor, it works fine and returns what I want. But when I try to access the cursor in code like so;
<br />
OPEN cur_ref_nos_with_rev;<br />
FETCH cur_ref_nos_with_rev BULK COLLECT INTO col_ref_nos_with_rev;
If falls over on the FETCH, giving me ORA-01001 - Invalid Cursor.
Anybody have any ideas?

It's not because you have two fields in your select statement and only one variable in your fetch statement? (Oracle not my strong point).
|
|
|
|
|
The variable in the FETCH is a strongly typed associative array of rows returned from the query. The table itself contains 500,000+ rows, this query returns about 300,000, so I want to grab it all in one go, do some processing, and then bulk update the database. That's why I'm using the BULK COLLECT. It's part of a proc that writes about 9,000,000 updates, so performance is an issue.

I'm writing the query given below which should give 5 rows which has ParentFragmentId as NULL but I'm not getting any row.
SELECT TOP (5) FragmentId, FragmentTitle
FROM Fragments
WHERE (ParentFragmentId = NULL)
ORDER BY CreatedOn DESC
|
|
|
|
|
Try:
SELECT TOP (5) FragmentId, FragmentTitle
FROM Fragments
WHERE (ParentFragmentId IS NULL)
ORDER BY CreatedOn DESC
