I'm using VC++ 6.0, and using the ODBC API to connect to the databse.
My question is that is there a way to find the limit of the number of fields permitted per Primary Key.
Eg. For MS SQL 2000/ 2005 limit is 16 or less fields for a primary key.
For MS Access the limit is 10 or less fields for a primary key.

I replaced the line in aspnet_UsersInRoles_AddUsersToRoles stored procedure
DECLARE @tbNames table(Name nvarchar(256) NOT NULL PRIMARY KEY)
with
DECLARE @tbNames table(Name nvarchar(256) COLLATE Database_Default NOT NULL PRIMARY KEY)

Hi,
In SQL Server Everywhere, there is no support for keyword "TOP" for selecting
limited number of rows. Can you give me any idea how can I perform similar task with this limitation ?
Thanks in advance

Hi;
If I understood your problem your trying to select a limited number of rows of your table?
What version of SQL SERVER are you using? If your using 2000 then the TOP keyword should work fine.
SELECT TOP 7 FROM LatestNews
Im using it with out problems.

Hi Riazi,
Thanks for your support.
I am using SQL SERVER EVERYWHERE 2005, which is a latest mobile and desktop database solution from Microsoft released very recently in this year. This is actually SQL Server Mobile upgraded version. And this SQL Server Everywhere doesnot support TOP and ROWCOUNT keyword. So, I thought there might be some tehcnique to perform this similar task.

As with all computer technology there are usually many ways to perform one task.
At our shop we're new at the whole SQL database process. On our old apps with our mainframe we have test databases, we make changes and then copy the framework of the test database into production.
With SQL we have two servers. A development server and a production server. What is the best way to move a database from our development server with select tables and select stored procedures.
Does the backup / restore process lend itself to this kind of move or should we be researching into DTS?
I'm looking for suggestions from those of you who have worked with SQL databases for years and can guide newbies to the best solution you've found.
Any suggestions are welcome

One way would be to have sql scripts that create new tables / stored procedures and update altered tables / stored procedures. Run these scripts on the production server after you've tested on the development server.
I am sure there are other ways, but this is the first to come to my mind

Using the enterprise manager you could choose the copy database item from the context menu. This could be used to copy the database and create a script to be run for later updates.

Cool!! 
That seems way to simple, but I tested it and it works great!!
Are there any drawbacks? Is it accurate creating the scripts or are there disadvantages to this method??
Thanks for your idea!!

Use scripts unless you want to update any changes by hand.

I would rather use scripts than doing the work by hand. I just don't always trust Microsoft, so it always helps to ask if there are any drawbacks to using the scripts that you copy. Maybe I should be more trusting, but with Microsoft sometimes it is hard.

I know that feeling.

I think we all would rather do the scripts When Enterprise Manager or SQL Server Management Studio Express generates the scripts, you can place comments into the script and this can serve as an audit point in the life cycle of the project. Always make a backup of the live data before running the scripts. I haven't had any serious trouble with running scripts whenever something is added/changed.

As long as you are just refreshing data from dev to prod this will work. As Paul says though if you change the schema you will either need to rerun the copy or modify the generated scripts.

Hi all,
Currently I am working on importing data from SQL 2000 database to SQL
2005
database. The original SQL 2000 database contains Japanese as well as
English text. For importing data from SQL 2000 to SQL 2005 I have followed
following steps.
1. I have created SQL script for generating table structure in SQL 2005.
Which I executed and it created table structure in SQL 2005.
2. I have created SQL script for generating stored procedures in SQL 2005.
This was also successful.
3. Same way, I have created user defined functions in SQL 2005.
4. But the problem comes while importing data to SQL 2005.
For this I have done following things.
- Exported the data from SQL 2000 database to an excel sheet.and
- Import to SQL 2005 database which is causing problems. 
There is no problem with importing data which is in English to SQL 2005.
But as we have to import Japanese text alongwith English, it is causing
problems.
* * * Error is * * *
"The character-string data type of the Unicode
form and the character-string data types of the form other than Unicode
cannot be converted by the row "Description".
So, I guess the problem is related to the importing of combination of
UNICODE and Non-Unicode data to SQL 2005.
So, please let me know if we can use some other alternatives for importing
of Japanese text to SQL 2005.
Any suggestion/solution from you on this issue is greatly appreciated.
Thanks in advance.
Thanks & regards,
Vaibhav

Hmmm..I have no idea if this is at all relevant, but it almost sounds as if you are using a form to do the import? Shouldn't you just be doing something akin to BCP or bulk copy or directly in code without involving a UI part at all?

Hi John,
Thanks for your prompt reply. As per your suggestion I executed bcp command in the command prompt.
URL referred :
http://www.databasejournal.com/features/mssql/article.php/3391761
First I used following command to export data from source table in SQL 2000 database table to a .bcp file
[DatabaseName].dbo.[tablename] out c:\file1.bcp -n -S[servername] -U[username] -P[password]
Next I used following command to import data to the target table on SQL 2005
database
[DatabaseName].dbo.[tablename] out c:\file1.bcp -n -S[servername] -U[username] -P[password]
But it looks to me as if I need to write as many statements to export/import data for as many tables.
Anyway, thanks again for your valuable suggestions as it gave me right direction.
Thanks & regards,
Vaibhav

Same way as you'd use it anywhere else.
You might, however, find that SCOPE_IDENTITY() is a better choice if you have a lot of other database interaction going on at the same time.
