I don't think you want to use isnull. I think what you are looking for:
where @skill is null or skill like '%'+@skill
Hope that helps.

Try and use Coalesce
Coalesce(@skill1,skill2,"")
|
|
|
|
|
As written, your query will return every row when either @skill1 or @skill2 is NULL because skill always matches skill throughout all rows.
Try something simpler like this:
((skill LIKE '%' + @skill1 + '%') OR
(skill LIKE '%' + @skill2 + '%'))
Concatination with a NULL value results in a NULL value. LIKE NULL will allways return NULL and therefore not qualify the row for inclusion. The OR will allow the other line to qualify or disqualify the row.
The added parenthesis are there for the OR. I have always had trouble with OR when I let the parser/compiler handle what is being OR'd.

hi,
i am getting an exception while inserting data into a ms access database in "da.Fill(ds);"
"No value given for one or more required parameters."
my code is like this
DataSet ds = new DataSet();
try
{
openconnection();
cmd = new OleDbCommand(query, con);
OleDbDataAdapter oda = new OleDbDataAdapter(query, con);
//fill the DataTable
oda.Fill(ds);
closeconnection();
return ds.Tables[0];
}
catch (Exception)
{
return ds.Tables[0];
}
finally
{
closeconnection();
}
thanks in advance

Dont you need to specify a table name in the oda.Fill(ds,"SomeTable")?

Firstly, you're attempting to fill a dataset with the results of a query, not insert data into a database with this code. Is that what you intended?
Secondly, the cmd object is not used. I don't know if you intended this. Passing the query string to the data adapter's constructor causes it to construct its own command object for its SelectCommand property. You can pass your own command object by using the version of the constructor that takes an OleDbCommand object.
I think the reason for the error is that the query string has one or more ? characters in it, indicating replaceable parameters, and you've not specified the values of those parameters. You'll need to use the command's Parameters collection for this.

I have an MS SQL Server 2005 database that uses data from another MS SQL Server database created by a third-party software company. Both are in the as instance.
I wish to create a stored procedure in my database to retrieve data from the third-party database.
The following code works fine :-
SELECT TOP (100) PERCENT NLNominalAccountID AS NominalAnalysisId, AccountNumber, AccountCostCentre AS CostCentre, AccountDepartment AS Department, AccountName<br />
FROM MMSv3_DemoData.dbo.NLNominalAccount<br />
ORDER BY AccountNumber, CostCentre, Department
The MMSv3_DemoData is the third-party database.
My problem is that I wish to my the database name an input parameter as have tried the following code :-
set ANSI_NULLS ON<br />
set QUOTED_IDENTIFIER ON<br />
go<br />
<br />
ALTER PROCEDURE [dbo].[spGetNominalAccounts]<br />
@Database AS VarChar(50)<br />
AS<br />
BEGIN<br />
SET NOCOUNT ON;<br />
SELECT TOP (100) PERCENT NLNominalAccountID AS NominalAnalysisId, AccountNumber, AccountCostCentre AS CostCentre, AccountDepartment AS Department, AccountName<br />
FROM [@Database].dbo.NLNominalAccount<br />
ORDER BY AccountNumber, CostCentre, Department;<br />
END<br />
What I get when executing the stored procedure is :-
Invalid object name '@Database.dbo.NLNominalAccount'.
Any help apprceiated.
Thanks

You have to build a T-SQL statement dynamically inside your stored procedure and then execute it using sp_executesql.
DECLARE @sql nvarchar(100)
SET @sql = 'SELECT * FROM ' + @Database + '.dbo.FOO'
EXEC sp_executesql @sql

The answer is always simple, when you know how.
Thanks alot, big help

I am getting an error in Replication between SQL Server 2005 and SQL Express when connecting to . "Connecting to Subscriber". The error message is given below. "Unable to complete login process due to delay in opening server connection". Why? Do we need to increase the logintimeout for "Connecting to Subscriber". How can we increase it?

Can you do an sp_attachdb to attach the database?

I have SQL Server Express 2005 running on Windows Server 2003. I installed SQL Express using pretty much all the default options (including Windows Authentication). The machine name is SQLBOX.
I have Visual Studio 2005 on my primary development machine; its name is DEVBOX.
I'm not in a domain environment. The account I use to log onto DEVBOX doesn't exist on SQLBOX, and vice-versa. That is, if I try to access a share, for example, on SQLBOX when I'm on DEVBOX, I'm prompted for a username/password (which I then provide as "SQLBOX/username" and that account's password). That's never been a problem.
I want to access a database on SQLBOX from within VS2005 running on DEVBOX. If I go to Server Explorer, select Data Connection, then Add Connections, I can see that SQLBOX is shown in the Server Name dropdown (meaning, DEVBOX managed to correctly enumerate all instances of SQL Server on my network).
The problem, at this point, is that if I leave the radio button on "Use Windows Authentication", I have no option to enter proper Windows credentials ("SQLBOX/username"). The "Select a database name" dropdown remains blank (since, I'm assuming, VS can't enumerate the databases on SQLBOX if it can't log on), and if I click either the OK or Test Connection buttons, VS simply returns with a timeout. I'm never prompted for a username/password, which fails because, I assume, DEVBOX/username is supplied by the system.
Does a Windows account with a matching name/password have to exist on both machines in such a scenario? Or do I have to change SQL Express so it uses SQL Server Authentication?
I've connected to other remote SQL machines with VS many times in the past, but I've always had matching accounts that existed on all machines. This is not the case here, so I'm assuming that's why this is now failing...
Incidentally, there might be something else at work here, because frankly I would've expected a more appropriate authentication error message instead of a timeout, but I've already gone through all the settings I could think of to allow remote access to the database, including using the Config Manager tool to allow both Named Pipes and TCP/IP...

Windows authentication is really only intended for use within a domain. The fact that it also works in a workgroup where the username and password are the same on client and server is a bit of an accident, coming from NTLM's workgroup file sharing support. You cannot specify a password for Windows authentication.
You will have to allow SQL Server authentication on the server. The reason it is generally not recommended is that the passwords are sent in the clear, so can be seen with a network analyzer. It is possible to secure the channel so everything, commands, passwords and retrieved data, are all encrypted - for this you need an SSL certificate on the server. See 'Encrypting Connections to SQL Server' in Books Online (e.g. look up 'SSL' in the Index). You then need to set Encrypt='true' in the connection string.
To enable SQL Server authentication appears to need a registry change, if you don't have Management Studio available. It may be easier to rerun setup, or to download SQL Server Management Studio Express from Microsoft.
Also, you should be aware that remote connections are disabled by default in SQL Server 2005 Express and Developer Editions. To enable them, go to the Configuration Manager tool and enable TCP/IP. You can also use SQL Server Surface Area Configuration but from memory that's not available for Express Edition. This may explain why the timeout occurs rather than getting a 'login failed' error.

Hi all again!
I am designing a web site ready to use both SQL and Ms Access DB.
I have a relation between say Picture and Category. When I delete a category, all the related pictures category will set to NULL. I have no problem with SQL, I set SetToNull in SQL but when I setting up relation in MS Access, I can't find any option, It raise an error when I want to delete category, how I can make MS ACC to set that field to NULL while deleting that record?
Thanks.

You asked this question in the ASP.NET forum on October 7th and I answered it. You shouldn't post the same question twice - continue the previous thread.

The database exceptions are pretty generic - to work out what's wrong, you'll need to look at the Message property of the exception. Then look that up in your database provider's documentation.
