Hi,
thank you for your reply, it helped a lot. However, I wasn't able to run it. It says this error:
Line 1: Incorrect syntax near 'RegisterUser'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near 'RegisterUser'.
Source Error:
Line 82: cmd.Connection.Open()
Line 83: cmd.Parameters.Add("@Password", inputHeslo1.Value)
Line 84: cmd.ExecuteNonQuery()
Line 85: '
Line 86: 'Dim vilemDA As SqlClient.SqlDataAdapter = New SqlClient.SqlDataAdapter
Source File: c:\inetpub\wwwroot\VilemWeb\Register.aspx.vb Line: 84
Here's a code:
Dim vilemConn As New SqlClient.SqlConnection<br />
vilemConn.ConnectionString = "...."<br />
<br />
Dim cmd As New SqlClient.SqlCommand("RegisterUser", vilemConn)<br />
cmd.Connection.Open()<br />
cmd.Parameters.Add("@UserName", txtLogin.Text)<br />
cmd.Parameters.Add("@Password", inputHeslo1.Value)<br />
cmd.ExecuteNonQuery()<br />
cmd.Connection.Close
and the stored procedure is here:
ALTER PROCEDURE RegisterUser<br />
( <br />
@UserName varchar(64), <br />
@Password varchar(64)<br />
)<br />
AS<br />
IF EXISTS(SELECT * FROM Users WHERE login=@UserName)<br />
BEGIN<br />
RAISERROR('The user CurrentUser already exists', 16, 1); <br />
RETURN<br />
END<br />
INSERT INTO Users (login, heslo)<br />
VALUES(@UserName, @Password)<br />
RETURN
BTW: It said an error when I had written in RAISEERROR '+@UserName+' instead of CurrentUser, don't you know why?

For the first problem it looks like I missed the line:
cmd.CommandType = CommandType.StoredProcedure You need to place this between creating the cmd object and the cmd.ExecuteNonQuery.

Ah! Just realised that RAISERROR doesn't like strings being concatenated inside it. Weird!?!
Anyway, try
DECLARE @error_message varchar(256);
SET @error_message='The user '+@UserName+' already exists.';
RAISERROR(@error_message, 16, 1);
Hopefully it should work out now.

I take my hat off to you!!! Your better help than MSDN. Thanks a lot, it works definitely. I am going to change all in my app to stored procedures, it's more clear than I did before. Thanks!

I'm not sure about that, I have to admit I've had 8 years to get used to the style. But thanks for the compliment, it is very welcome.
Have a great weekend.

Just wanted to say that I thought your reply here was really good. I agree - I would never build a database that didn't work through stored procedures. I was shocked to find out that MySQL does not support them, I immediately stopped considering it when I found out.

Really! I heard also that it doesn't support transactions either (although there is supposed to be some sort of plug in that gives this functionality). That is the biggest showstopper for me.

I am porting an enterprise level 3-tier C++ application to C# with a tight timeline. I am confused with the database jargon in .net Can somebody advice me on which objects/wizards can satisfy following requirements:
1. Compatibility with multiple database vendor (Oracle and MS SQL to start with)
2. Transactional control
3. Ability to fetch XML from query results
4. Ability to operate on views and execute stored procedures
Can some expert guide me?

1. .NET provides classes optimises for MS SQL, but also has a generic set of classes that I believe can connect to anything that is generally connectable to
2. Why don't you control transactions in stored procedures ?
3. The SQLCommand class has an ExecuteXMLReader method that should do this
4. The SQLCommand class does this all, you just give it the stored procedure name, tell it that it's a stored procedure and add to the parameters collection. Make sure any parameters that are not just 'in' parameters get set to whatever they are, or they will never come back to you.
Overall, I recommend buying the ADO.NET book from Microsoft, it answers all these questions and is a good reference to have.

Hi,
I have a Main Form, with controls, which are dynamically being populated from the database on FormLoad Event. There is a button called "Run Query", when I click this button, I want the result of the query to be displayed in a "Child Form" in a DataGrid, with sorting and paging facility and also a column in the "data grid", which allows me to edit the selected records.
Any working examples or help is appreciated.
Thanks

Hi,
Im trying to connect to an sql server through a PDA. When I use the PDA over a LAN network, it works absolutely fine, but when I try to connect to the sql server through Wi-Lan using the same PDA, I get an error saying that "Could not find assembly resource". Can anyone tell me the reason?
One thing that while switching from the LAN network to the Wi-Lan network, my IP address changes, so do I need to restart the Sql Server? Cant figure out the actual cause!

Hello
I am working on very simple SQL query but the resultset is not what I am waiting for.
cmdSelectConfigurations.CommandText = "SELECT Config_Number, Config_Type, " +
"Model_Serie, Serial_Number, Install_Customer_Nb, Install_Customer_Name, " +
"Install_Postcode, Install_City, Star_Zone, Install_Date " +
"FROM Configurations WHERE Config_Type like @Config_Type";
cmdSelectConfigurations.Parameters.Add(new SqlParameter(
"@Config_Type", SqlDbType.Char, 10, "Config_Type"));
cmdSelectConfigurations.Parameters["@Config_Type"].Value = @"%" + Search.ConfigType + @"%";
the character '%' seems to not be understanding, it seems to be understanding like '_'.
It considerates only one charactere before and after the value.
The query is OK when I put "'%" + AValue + "%'" directly in the Command text.
but it is always wrong when I try to use a parameter.
Thank you for your help

Just a WAG (Wild Ass Guess )
Change to
cmdSelectConfigurations.Parameters["Config_Type"].Value = "%" + Search.ConfigType + "%";

I have tried all possibilities to write the value of the parameter.
Finally,I have changed the size of the parameter from 10 (the size of the field in the table to 12), and now the query is OK!
I am not sure that is a good solution, so maybe I will do a stocked procedure...

I am working on a product where depending on some metadata associated with a table column my presentation of the table contents changes. For example a user may say a column is bold and in the reports it should be printed bold.
If the table schema is fixed I could have done this by maintaining another table which maps a column with its display attributes. Problem with this scheme is both my table structure and the display attributes are user configurable.
So I think the best solution will be if I could make use of any built in database functionality to store the metadata. For example MS SQL Server has a description associated with each table column, which I can (hopefully) manipulate programmatically.
I would like to know is there a universal way to store and retrieve metadata about a database table column?

You would have to maintain your own metadata. You could, for ease, link it to the existing metadata.
You could create your own metadata table with this schema:
CREATE TABLE MyMetaData
(id int,
colid smallint,
is_bold bit....) -- Add your own metadata as needed
The primary key is on id & colid
id is the iditifier from the sysobjects table (which contains a list of the tables umong other things)
Does this help?

Yes, I think this would work. Thanks a lot, man.
This is a better solution than my original idea, as it is extensible. The only minor problem it would have - if users delete columns from their tables, the corresponding entries will unnecessarily remain in MyMetaData table. But this is a negligible problem.
Anybody else has any better/easier solution?

SELECT A.A+B.B
FROM (SELECT 1 as A) AS A
INNER JOIN (SELECT 2 as B) AS B ON 1=1
For this to work each subquery (the selects inside the brackets) must return exactly one row only.

Hi all,
anyone know if there is a way to convert an SQL Server script (i think it's TSQL?) to an Oracle script (i think its PL/SQL)?
Converting it by hand is giving me a royal headache.
Thanx in advance.
