This is the code that creates the stored procedure
CREATE PROCEDURE DeleteUser
@userId int
AS
DELETE FROM LoginInfo WHERE uid = @UserId;
GO
Here is the snipped that calls the stored procedure from C#
int userId = int.Parse(user_id.Text);
SqlCommand cmd = new SqlCommand("DeleteUser");
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = myConnection;
cmd.Parameters.AddWithValue("@UserId", userId);
cmd.ExecuteNonQuery();
You should, hopefully, be able to figure the rest out from this example.

Hello,
is there a way on how to insert a new row into an MS SQL table that only contains an autogenerated primary key column?
Thanks,
Michal

What are you inserting into the row? You might want to reconsider the design of only having one column and it being auto.

Paul,
thanks for the reply.
It's exactly what my design is. There's just one column and it is being autogenerated.
Let's say this table is named Table_A. The sole auto int PK column in Table_A is named Table_A_Id.
Let's say there's another table, Table_B. This Table_B contains, among other things, a column named Table_A_Id. There is a foreign key relationship between Table_A.Table_A_Id and Table_B.Table_A_Id. By way of this FK relationship, the unique Table_A.Table_A_Id rows are being linked to many Table_B.Table_A.Id rows.
Each time I insert a new row into Table_A, I get the last autogenerated PK by issuing SELECT @@IDENTITY. I take this last PK from Table_A and insert multiple rows to Table_B that link to this Table_A.Table_A_Id.
The problem is that if Table_A only contains one autogenerated PK column, there's actually nothing to insert (no columns, no values) into Table_A. My current workaround is that I've added a text column named Comment to Table_A. I'm generating a new row in Table_A by issuing INSERT INTO Table_A (Comment) VALUES ('') then.
But I'd like to find out how to generate a new row in Table_A with no workarounds.
Thanks much,
Michal

Why on earth do you want a table with only an autogenerated column on it? That's just begging for somebody to point out that you've failed the database normalisation test here. Plus, don't use @@IDENTITY to get the identity of a column. Use SCOPE_IDENTITY() instead.

He explained it to me in his reply to my post. But he still makes no sense and yes, he really blew the database normalization here.

Is there also a Table_C which has as a column, Table_C.Table_A_Id? I've come across this a few times and other than adding an extra column as you suggest, you can also go without using Auto. But instead you write a trigger that peforms the logic that an Auto would do you for you normally.

You really should redesign your tables, because like Pete said, this is a failure at database normalization.

Table_A contains no data. All it contains is a surrogate key, a key to look up nothing.
If you really need the list of values that you expect in Table_A, then a select distinct(Table_A_Id) from Table_B will serve its purpose.
If you want to constrain the column in Table_B to a set of values, then use a constaint.

In SQL Server 2005,
If not caring about normalization, NEWID() will autogenerate a uniqueidentifier
INSERT INTO [GSTDB].[dbo].[TableName]
([Field1])
VALUES
(NEWID())
GoodLuck!!

Hello Friends,
I want to get the information of the record(s) where SmallImage(Field Name) must be unique. For this i'm using the following query. Is it right or not if not plz make it correct
Select * From Gallery1 Where SmallImage in (Select Distinct SmallImage From Gallery1 Where Active=1)
|
|
|
|
|
hi Friend
try this
select * from Gallery1 where SmallImage = "whatever" And
Exists (Select Distinct(SmallImage) From Gallery1 Where Active=1)
Remember you have to Assign a value in the First select statement.Think of it this was. you want to select all the records in a table called "Gallery1" where Value is equals to "that", and from the above Query display the records Distinctively.
hope it helps
Thanks

Sorry Friend,
The code you sent is not working properly
Select * From Gallery1 Where SmallImage='~/Gallery/Bhaiji in USA/Small/IMG_0028.jpg' and SmallImage in
(Select Distinct SmallImage From Gallery1 Where Active=1)
The code is given above only giving the records that include the SmallImage='~/Gallery/Bhaiji in USA/Small/IMG_0028.jpg'

hi Friend, here is your Mistake. i have sent you the Query that looks like this
select * from Gallery1 where SmallImage = '~/Gallery/Bhaiji in USA/Small/IMG_0028.jpg' And
Exists (Select Distinct(SmallImage) From Gallery1 Where Active=1)
And you sent me that give you a Problem now ,that looks like this
Select * From Gallery1 Where SmallImage='~/Gallery/Bhaiji in USA/Small/IMG_0028.jpg' and SmallImage in
(Select Distinct SmallImage From Gallery1 Where Active=1)
if you can look at the Above Queries, they dont look the same. the First Query is what i recommended and the second query, its yours and you did not use the "Exists" and you used SmallImage again, and SQL does not know what to do with it, its like an used variable but declared.
try the first one and tell me what you get
Hope it helps
Thanks

My requirement is to read data from Oracle using BizTalk (XML) and write to SQL Server.
Looking for recommendations.
Thanks.

Why? You can do this by reading the data from SQL Server using SSIS (SQL Server Integration Services) which is perfectly capable of transforming data from other database sources.

Hi,
I am using Sql Server Reporting Services in my asp.net web application. I am displaying the reports in reportviewr.
Whenever there is some data its ok. But When The Stored Procedure or query didn't produce any result the report viewer appears and take usual place(i.e width and height).
My requirement is that if the stored procedure or query returns data then the report viewer will be visible along with data. Else the report viewer should Hide and display Record Not Found.
Issue:
--------
As the .rdl file is directly related to stored procedure or query we r not fetching any datatable into the page.
Any Suugesstions or Solutins heartly Accepted....

Data bound controls in SSRS have a NoRows property which allows a message to be defined which will only be displayed when the data source that the control is bound to does not return any data.

I need to store a time such as 5:00 PM in a table column in SQL SERVER Express 2005. I do not need to store any data about the date. I know that I could store this as text, but I know I should store it in a datetime data type. Should I create a user defined type just for time?
When I first was writing the database I found an article in a forum where users were saying that when they needed to store a time with no date they were using a text field. Then I posted a message in the VB.NET forum and I was told that it would be a big mistake to store a time in a text field.
What should I do?
