You can write valid TSQL in different steps of your SQL jobs. In Enterprise Manager navigate to database server->Management->SQL Server Agent->Jobs and define a new backup job.
For example, I have a back up job defined in EM with one step having following code.

Declare @fileName nvarchar(250)
Set @fileName = N'C:\DBDailyBackup' + Replace(Replace(Replace(Convert(nvarchar(50), GetDate(), 20), ':', ''), ' ', ''), '-', '') + '.bak'

BACKUP DATABASE [pubs] TO  DISK = @fileName WITH  NOINIT ,  NOUNLOAD ,  NAME = N'pubs backup',  NOSKIP ,  STATS = 10,  NOFORMAT

You can also do it from Right click context menu on your database, choose All Tasks->Backup Database and define as schedule. Needless to say that you have to have SQL Agent service running for it to work properly.

i need to create a SQL query in my C# code,
serching for all selected control voices.
I have 3 or more controlls (combobox)
If the user select a voice for the first and third one for example i need to create a query made like this:
Select * from myTable where...
Value N = ComboBoxN Selected Voice
loop

i've tried but i doesn't work.
If i try a multiple join yes, but how can i realize it?

Your question doesn't make any sense to me. However, perhaps this is what you are looking for:

SELECT * FROM MyTable
WHERE (someColumn = @comboBox1Value AND @comboBox1Value IS NOT NULL)
OR (someColumn = @comboBox2Value AND @comboBox2Value IS NOT NULL)
OR (someColumn = @comboBox3Value AND @comboBox3Value IS NOT NULL)

Database, selecting the primary key

steve_rm5-Dec-05 5:06

Hello,

I have a table called customer. I have other tables, but they are not important regards to this question.

This hold customers' details for their online account for a supermarket.
The fields are the following:
CustomerID bigint identy seed, Primary Key
Username nvarchar
Name nvarchar
Address nvarchar
City nvarchar
Postcode nvarchar
Password nvarchar

My question is. Do l need the customerID field as primary key. As username will be a unique value. No one will have the same username.

Like for e-mails, l have a username that is unique. Would I have another id as well. For e.g. Does yahoo have our usernames as our primary key fields?

I was thinking of desiging this database without the customerID, and only having username as the primary key.

Thanks in advance,

Steve

If the user name is unique and invariant make it the key...however if it can be changed or is not unique you shouldn't.

Using a User name as primary key is probably a bad thing. Think about it how many Mike Smiths are there in the world? The answer is there are a lot of duplicate names in the world.

Do you think everyone of your customers are willing to give you their email address? What about the poeple in the world that don’t have email?

Seems to me your better off using the int as a primary key for the table.

Just my 2 cents...

Can anyone tell me why I am not seeing any SQL Server 2K user defined functions in the server explorer in VS.2003. The documentation talks about running a udf in server explorer by right clicking a udf in the udf folder - Well I ain't got no stinking udf folders in any SQL Server databases although I know they are there.

Thanks

Binding Database to multiple controls

This was posted in the VB forum as well since I was not sure which it pertained to.

Ok, not sure exactly how to word this so here goes. I have a winform in my project that has the following:

Controls

1. DropDownList1 - Customer Name
2. TextBox1 - Customer ID
3. DropDownList2 - Site Name

DataBase Tables

1. tblCust - Fields(CustName, CustID, Status)
2. tblCustSiteAssoc - Fields(CustId, CustSiteID)
3. tblCustSite - Fields(CustSiteID, CustSiteName, ...)

What I am trying to do is this:
1. When the form open have customers names bound to the DropDownList1 control with nothing selected
2. Once I select something in the DropDownList1 control (SelectedIndexChanged) have it update the other two controls with the selected customers' data.

I assume I make a DataSet that queries all three tables and I understand how to bind the CustName to the first DropDownList box. What I don't understand is how to use the selected information to get the relevant information for the other two controls.

Thanks in advance,

Taen Karth

Probably not directly, but there is nothing stopping you from creating a Windows DLL that wraps the ADO class heirarchy in a set of public functions. This DLL could then be used in straight C.

This DLL is not only be used by C, but also other client languages like Delphi, Borland C++, VB.NET etc. I am still figuring out how to wrap this ADO in the DLL so that it can be called by all client languages. Do you have any sample code or references that I may refer? Thanks.

Hey everybody,
I know this a pretty silly question but I totally blanked. I'm looking to remove duplicate results from the results set (NOT the table).

Say I have a query like so:
SELECT SomeNumber FROM MyTable ORDER BY SomeNumber ASC
returns the following set:
1
1
1
2
2
3
4

But I want it to return:
1
2
3
4

What extra criteria would I add to the query?

Thanks in advance for your help.
