Checking the record in the procedure for update is always secure. It doesn't take any extra overhead in your program but it is additional as well as perfect checking fot data concurrency

Update table1 set col1 = replace(col1,'_','')

ok, i get it 
Thanks a lot for help, Dinuj Nath

How about::
Update table1 set col1 = 'HIGH COST'
|
|
|
|
|
I think the previous 'replace' sql statement is more suitable for me because the data that I wanted to remove those underline have different value, not just for 'HIGH COST' only
Anyway, thanks again for your suggestion.;)

Try
oSqlCliCon.Open()
Catch ex As Exception
msgbox(ex.Message)
End Try
oSqlCliCon.Close()
End Sub
The problem:
The code works for VB6/VBNET/VBNET2003 for SQL SERVER
for VBNET2005 works only local but for the SQL SERVER don't.
The exception message:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
The exception message if modify the connectionstring:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Please help, thank you.

I've been researching this but am confused on how to set up the syntax.
I have a stored procedure that bascially does the following:
1. Recieves two parameters: a part type, and a part number. The part number is actually a varchar.
2. Inserts the part type ID (taken from a second table called PartTypes) and Part Number into the table Parts.
3. The table Parts has a third field, ID which is an auto-incrmemented number. (Apparently the "Part Number" can change so we use this auto-incremented ID to reference the part number in other tables to keep things simple if the number changes.)
Okay, what I need to do is once that gets inserted into the Parts table, I need to use that Parts.ID that the system assigned. I need to send it back to the page that called it.
So two questions:
1. how do I set up this OUTPUT thing? The code I found online wasn't very helpful. Here is the stored proc:
CREATE PROCEDURE [dbo].[UpdatePart_Step_1]<br />
@PartNumber varchar (15),<br />
@PartTypeDescription varchar (60) <br />
<br />
AS<br />
declare @pt_id integer<br />
<br />
if NOT EXISTS (Select * from Parts where PartNumber = @PartNumber)<br />
BEGIN<br />
<br />
SELECT @pt_id = pt.ID FROM PartTypes pt <br />
<br />
INNER JOIN Parts p on pt.ID = p.PartTypeID<br />
<br />
WHERE pt.Description = @PartTypeDescription<br />
<br />
insert into Parts<br />
(PartNumber, PartTypeID)<br />
<br />
VALUES<br />
(<br />
@PartNumber,<br />
@pt_id<br />
)<br />
END<br />
return 0<br />
GO
2. How do I get this value back into the original page that called the stored proc?
My thinking is that I should create a completely separate stored proc to get this Parts.ID, but I'm not sure what the norm is.
Thanks again all!

CREATE PROCEDURE [dbo].[UpdatePart_Step_1]<br />
@PartNumber varchar (15),<br />
@PartTypeDescription varchar (60),<br />
@ID int OUTPUT<br />
AS<br />
declare @pt_id integer<br />
<br />
if NOT EXISTS (Select * from Parts where PartNumber = @PartNumber)<br />
BEGIN<br />
<br />
SELECT @pt_id = pt.ID FROM PartTypes pt<br />

@pt_id<br />

END<br />
SELECT @ID=@@IDENTITY<br />
return 0<br />
GO<br />
And here is the code from client side
<br />
Dim cmd as new SqlCommand("UpdatePart_Step_1", connection)<br />
cmd.CommandType=StoredProcedure<br />
cmd.Parameters.Add("@PartNumber", varchar, 15).Value="Anything"<br />
cmd.Parameters.Add("@PartTypeDescription", varchar, 60).Value="Anything else"<br />
cmd.Parameters.Add("@ID", int).Direction=ParameterDirection.Output<br />
cmd.ExecuteNonQuery()<br />
Dim res as integer=cmd.Parameters("@ID").Value -> Returning value from SP<br />
Hope that help

How would I do this in C#? This is my code that calls the stored proc:
ds2 = new DataSet();<br />
SqlParameter param1 = new SqlParameter("@PartNumber", strPartNumberInputReference); <br />
SqlParameter param2 = new SqlParameter("@DwgNumber", strDwgNumber);<br />
SqlParameter param3 = new SqlParameter("@DwgRevision", strDwgRevision);<br />
SqlParameter param4 = new SqlParameter("@DwgLocation", strDwgLocation);<br />
SqlParameter param5 = new SqlParameter("@PartTypeDescription", strPartTypeID);<br />
<br />
ds2=SqlHelper.ExecuteDataset(this.connectionString, CommandType.StoredProcedure,"dbo.UpdatePart_Step_1", param1, param5);<br />
dt2 = ds2.Tables[0];
Thanks again for your help!

Hey there.
I just installed SQL Server express 2005 yesterday and I'm trying to connect to it using C# on Win 2000 SP4. I've never used SQL server so this is probably a novice question.
I used the following connection string to connect
SqlConnection conn = new SqlConnection("Data Source=localhost; Integrated Security=SSPI; Initial Catalog=pubs");
However, I get the following error:
Exception Occured -->> System.Data.SqlClient.SqlException: An error has occurred
while establishing a connection to the server. When connecting to SQL Server 2
005, this failure may be caused by the fact that under the default settings SQL
Server does not allow remote connections. (provider: Named Pipes Provider, error
: 40 - Could not open a connection to SQL Server)
I am running the SQL Server service. I see the sqlservr.exe in the taskbar but I'm not sure if it is actually running.
Anyone know how I can connect to the sql server from C#?
Thank you!

On SQL Server Express, the name of the datasource is like "SERVERNAME\SQLEXPRESS" where SERVERNAME is replaced by the name of your server. Rather than localhost, may be you can try the above syntax and check if it works.

Indeed! Thanks for your help god_bless.
Here is my final connection string:
SqlConnection conn = new SqlConnection(@"Server=.\SQLEXPRESS; Connect Timeout=5; Database=myTestDb; User ID=****; Password=****");
Also, since I am not using Windows authentication, I had add a user which I accomplished by
SQLCMD.exe -S (local)\SQLExpress -E
> EXEC sp_adduser '[machineName]\[userName]', '[userNameInDB]'
> GO
> EXEC sp_ addsrvrolemember '[userName]', 'sysadmin'
> GO
These steps are from this (excellent) tutorial: http://www.aspfree.com/c/a/MS-SQL-Server/Configuring-SQL-Server-Express-2005/
Finally, I made sure that the server was listening for the user I specified instead of some other user; that got rid of my Login Failed attempts.
Then, it finally worked!

Hi;
I have this big problem in .net 2005 (C#). In the previouse version (2003) when we made a stored procedure we could simply drag and drop it into the screen and VIOLA you had all the code you needed for the procedure and with a little touch everything was fine. Now in .net 2005 I can't do that anymore or at least I dont know anyway. Could some one help me on this please or at least present another solution or 3rd party tool I could use.
I realy need to use SP.
Thanks very much

We have Microsoft SQL Server 2000. The database inside has very minimal information in it yet it uses 4 gigs of space. Why is it so big and how can we reduce its size?

Hello,
Im trying to create a SQL string that will insert values (Values that were gathered from a ASP.NET web form) into a table. The values are C# variables. I can insert manually typed values 'string' but when I try to make it a variable , I get an error. ORA-00984: column not allowed here. I either need the correct syntax for the sql string (values) or need to know the correct method for inserting C# variables into an oracle database.
Using MSVisual Studio 2005, ASP.NET webform, C#, Oracle 9i DB.
Sample of the code Im using...
protected void SubmitBtn_Click(object sender, EventArgs e)
{
String TodayStamp = DateTime.Today.ToString();
String EnteredFirstName = FirstNameTxtBox.Text;
String EnteredLastName = LastNameTxtBox.Text;
String EnteredCompany = CompanyNameTxtBox.Text;
String EnteredEmail = EmailAddTxtBox.Text;
String EnteredCity = CityTxtBox.Text;
String EnteredState = StateDropDownList.SelectedValue;
String EnteredCountry = CountryDropDownList.SelectedValue;
string strSQL = "INSERT INTO table(Firstname, Lastname, Company, Email, City, State, ActivityDate, Country) VALUES (EnteredFirstName, EnteredLastName, EnteredCompany, EnteredEmail, EnteredCity, EnteredState, TodayStamp, EnteredCountry )" ;
OdbcConnection conn = new OdbcConnection(ConfigurationManager.ConnectionStrings["DBConn"].ConnectionString);
OdbcCommand myODBCCommand = new OdbcCommand( strSQL, conn);
try
{
conn.Open();
myODBCCommand.ExecuteNonQuery(); **Errors Here**
}
catch
{
}
finally
{
conn.Close();
}
}
Can anyone help please??
thanks...
David
