hi,
i want to remove identity check for a table, i used SET IDENTITY_INSERT ON but it works just for one transaction,how can i disable identity forever
(i need the Transaction for this operation)
|

Alter the table, change the identity field to an ordinary integer (remove the identity attribute). Of course you will then be responsible for computing the value for new inserts... You could set a Unique constraint on the field to insure that it still rejects duplicates.

i'v been with crystal report last 4 years ,crystal report 8.5 version still stable than crystal report 10 version,i've scene few things that crystal report can fail
1.) once you create or call a crystal report your are not allow to change the order of columns in table that you refer for crystal report,you can add columns to table but always below other columns,cant replace the order.
note :- if you done those things you have to create or call reports again

Asp.Net (development or production box) does not run in the same security as you do. It most likely does not have rights to the database. Create a SQL login with the correct rights on the SQL Server and update your connection string.

You will have to access via TSQL if you don't have Enterprise Manager.
See:
sp_addlogin
sp_addUser
sp_grantdbaccess
on MSDN as a starting point.

Hi
I have 3 tables
Product(productID , productName , styleID , artistID )
, Artist(artistID , artistName )
, Style(styleID , styleName ) and relationShips :
Style 1 ---> N Product
Artist 1 ---> N Product
and this Command :
oleDbCommand = new OleDbCommand (
"select Product.productName , Artist.artistName , Style.styleName from ( Product inner join Artist on Product.artistID = Artist.artistID inner join Style on Product.styleID = Style.styleID )where productID = @productID", oleDbConnection );
But I got error :
Syntax error (missing operator) in query expression 'Product.artistID = Artist.artistID inner join Style on Product.styleID = Style.styleID'.
|
|
|
|

Try this:
SELECT Product.productName, Artist.artistName, Style.styleName
FROM Product
INNER JOIN Artist on Product.artistID = Artist.artistID
INNER JOIN Style on Product.styleID = Style.styleID
WHERE productID = @productID
Note: The only difference is that I removed the brackets. With the brackets it was expecting a subquery which you don't use here.

The code you attribute to me is not my code. I always write SELECT, FROM, INNER JOIN, WHERE etc. in upper case. Also I never put a space before a comma, only after it.
The code you say that works has a syntax error in it. This is obviously not the code you are using. If you are going to take code from your application please copy and paste it properly rather than rewrite it.
Also, in what way does the first not work? The only difference between the two is that in the second the join to "Style" has been removed. Could it be that the Style table has no rows that join on to the Product table? If that is correct then, naturally, the result set will be empty.

Okay, fair enough then.

Hmmm.... There is an additional comma before the FROM on the second command. So I can only assume that it wasn't copied and pasted from visual studio properly.
What is the exact error? It is a bit vague saying "I got a syntax error" without actually seeing the error message. SQL Server contains almost 4000 error messages that help point to the cause of the error. This is useful information and should not be discarded while searching for a solution.

Hi,
I am reviewing existing code and stumbled across something that, to me - and I'm new to ADO.NET, seems very awkward. A DataSet is filled using a OleDbDataAdapter. The weird thing is that the command does not affect any records at all, intentionally. It looks something like "SELECT ... WHERE 0 = 1".
The comment describing the method containing this code says "Retrieve an empty dataset that contains the database structure". DataSet Quick Whatch reports the dataset to be empty after the fill.
Does this SELECT statement really do any good? 
Thanks for comments, ideas or advise!

I don't use datasets because they tend to encourage the data layer to get too close to the presentation layer (not good design). The SELECT statement returns, as you've already noticed, an empty set. But that isn't to say that nothing at all was returned. I'm guessing that the empty DataSet is subsequently used to look at the data schema without actually needing to get any data. Obviously, it would be wasteful to get data that isn't going to be used.

This is usually a way to get an empty dataset with the correct stucture. It may be used for collecting and adding new rows to the database or perhaps merging data from another program layer before updating the database. I sometimes use this in large stored procedures which produce mutitable datasets; some of the tables may be empty, but my data layer expects the table structure to be there so I can add relationships, so I use a WHERE 0 = 1 to create an empty table.
