no - thing is, because I want this to be highly optimized and best place to put the logic is actually in database. Dilemma is now i have to give away the source code.
Perhaps what I can do is to encapsulate only half in stored proc, the other half in obfuscated dll =)

you can use encryption. Eg.
create proc MyProc with Encryption
(
@parameters....
)
as
select query.....
BTW why dont you use .

hope it helps...

AFAIK you could play around with the permissions, ie execute only to all but the developer. This will not secure your code but will reduce your exposure. The actual text of the code is stored in a sys table and is accessible to anyone with the right permissions (sa) and the knowledge to get at it.
I'd go with the license option - most clients are not SW people and only want to use the toll not reinvent it.

When using
SELECT ROW_NUMBER() OVER (ORDER BY id) AS [RowNumber]<br />
FROM table where RowNumber > 1
It returns error 'Invalid column name 'RowNumber'. What is the problem here? I'm using SQL Server Express 2005. Thanks.

You added 'RowNumber' as a column-name alias. Those can be used in the ORDER BY clause, but can't be referenced in the WHERE part. Since you're using SQL 2005, you can bypass this by using a temporary query, selecting into a new CTE first;
SELECT * FROM
(
SELECT ROW_NUMBER() OVER (ORDER BY ID) AS [RowNumber]
FROM [YourTableNameGoesHere]
) AS CTE_TMP
WHERE [RowNumber] < 10

I have a procedure running with transaction used in it.
I have used multiple insert in the procedures and finally return the scope_identity() of one of the insert by first setting a variable with scope_identity() and then returning it with select @variable at the end of procedure after commit and in case of RollBack i m returning it as select -9
The issue what am i facing is that sometimes it is skipping the return value in case of Commit Transaction as it is not returning anything to the code.
I am using it like this:
Full Procedure Code with Insert Commands here
set @variable=scope_identity()
IF @@ERROR <> 0
BEGIN
-- Rollback the transaction
ROLLBACK
Select -9
END
COMMIT
select @variable
The procedure is not going in the @@ERROR section and also all the insert values are there in tables after commit but why sometimes it is not returning the value required. I am using ExecuteScaler in the code.

You are not setting your variable:
set @variable=scope_identity() <br />
IF @@ERROR <> 0 <br />
BEGIN -- Rollback the transaction <br />
ROLLBACK <br />
Select <big>@variable =</big> -9 <br />
END<br />
COMMIT<br />
select @variable

I am saying it is committing the records not giving any error and rollback. It is not returning the value in case of committing the records.

Without the rest of your code its kinda hard to say then.

Hi All,
I have an existing database with a table schema that I need to change. However it seems that there is a conflict in the conversion. I'm trying to change a ntext column to a nvarchar column. I'm using C# Express 2008.
I've tried doing it on an empty table with the connection closed but I still see this error. What's the best way to tackle this schema change? I don't like the idea of having to recreate the table from scratch. As I understand it there is no way to script an SqlCe database ...
Any pointers would be great.
Thanks,
|

wow, you still can't do this in sql2008?!
One approach is to create a whole new column with the required type, then copy the content from the old column into it & delete the old column. Of course, the column names cannot be the same, so you'll need to use sp_rename at some point.
Unfortunately, this can get very tricky when there are other constraints in the database that rely on your column (default value is probably most relevant here). Also, be aware of the 4000 character limit of nvarchar.
There's lots of tools out there that will assist with this kind of change. We use xSqlObject here, which is excellent (www.xsqlsoftware.com/Product/Sql_Schema_Compare.aspx[^])
Best of luck!

Thanks for this. I came to the same conclusion. Also I'm using SQLCE ... is the nvarchar limit 4000 characters for this version? I think it's actually 255 ...
|
|
|
|
|
A quick google suggests the limit is still 4000... don't know though, i've never used CE

hi all,
i am trying to install SQL express 2005 from following code
str = Application.StartupPath & "\SQLEXPR32\setup.exe /qb ADDLOCAL=ALL INSTANCENAME=" & InstanceName & " SECURITYMODE=SQL SAPWD=mypassword DISABLENETWORKPROTOCOLS=0 "<br />
Shell(str, AppWinStyle.Hide, True)
it works well for first time. When i install from above code and uninstall from Control panel and then once again i execute the above code then it does not install the SQL server Express
I think Uninstall from control panel does not completely remove the SQL server Express.Its require some more steps
Whether anybody can suggest me that how can i completely uninstall the SQL server Express from my machine ?

Hello All,
I've been googling and based on many articles I belive what I'm asking of sql2000 triggers is not possible for the particular type of error i'm getting.
I am trying to integrate with an existing application on sql 2000 without affecting it's behaviour. When it inserts/updates/deletes in a few tables I need to perform an I/U/D in a sql 2005 DB through a DB link. This is all set up fine, as well as the trigger to do the insert. I need to be able to put error handling in the trigger so that it does not affect I/U/D of the existing product.
Right now, MSDTC is having a fit because I don't have it configured properly on purpose. I did configure it correctly and then reverted so it would raise errors so I could test error handling.
Nothing I've tried so far will let me handle this error in an insert trigger on sql 2000:
Server: Msg 7391, Level 16, State 1, Line 2
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction. OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator.
Execution stops immediately so I can't even get to an "IF @@ERROR" statement and the transaction is rolled back. I know how to fix this error but I need to be able to handle this type of error so I can use xp_logevent or something similar to monitor. Is it possible - Any ideas?
Does anyone know of a way in sql 2000 to handle this type of error in a trigger on sql 2000?

Hi Guys,
I am having problem when running the Following SQL script.It takes Pretty long time to return result.
I am having about 500,000 records in my database.
select count(distinct(CR_Cli)),SO_name from Callrecords inner join dbo.StudioOperators
On CR_StudioOperatorID=SO_ID
where datename(month,cr_callstart)='April'
and Cr_cli not in (select Cr_cli from Callrecords where cr_callstart<'2009-03-31')
group by SO_name desc
Is there any way i can write this script?
Thanks you very much.

In SQL Server Management Studio, place this query in the workspace and click on the icon that has a description of "display estimated execution plan". This will give you an idea of where there may be table scans and where you might be able to add an index to improve your performance.
You should also check to see if your statistics are updated on the tables and indexes involved in this query before running the "display estimated execution plan" as described above.
