How to Handle Multiple User update same table

Glenhew — Wed, 20 Mar 2013 10:30:07 +0800

hello, i has a question regarding how to handle multiple users update same table at the same time

for the example:

there has a button to allow user to click and generate Sequence No.

but if more than one users click it at the same time. Then the Sequence No will be duplicate & skip one No.

can anyone know how to solve it ?

CODE

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim sqlcmd2012 As SqlCommand
Dim conn2012 As New SqlConnection
Dim strconn2012 As String = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
conn2012.ConnectionString = strconn2012
conn2012.Open()
Dim cmdstring2012 As String
cmdstring2012 = "SELECT NextNumber FROM SequenceNo "
sqlcmd2012 = New SqlCommand(cmdstring2012, conn2012)
Dim myreader2012 As SqlDataReader
myreader2012 = sqlcmd2012.ExecuteReader

Dim SequenceNo as string
While myreader2012.Read
SequenceNo = myreader2012("NextNumber")
End While
myreader2012.Close()
conn2012.Close()

'update next number
Dim sqlcmd11 As SqlCommand
Dim conn11 As New SqlConnection
Dim strconn11 As String = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
conn11.ConnectionString = strconn11
Dim cmdstring11 As String
cmdstring11 = "UPDATE SequenceNo SET NextNumber = NextNumber + 1"
sqlcmd11 = New SqlCommand(cmdstring11, conn11)
conn11.Open()
sqlcmd11.ExecuteNonQuery()
conn11.Close()
'****************
End If

End Sub
