VB.Net Parameterized LIKE query - vb.net

Question

I am writing a code that will filter account numbers with the format zone-rate-customer_number. An example of that is 125-12-35, where 125 is the zone, 12 is the rate and 35 is the customer number. In my search textbox, I want to enter the zone and the customer number, this will exclude the rate. Here is my code
Dim search As String = txtsearch.Text
Dim sql As String = "SELECT * FROM tblCustomer WHERE [account no] LIKE '%' + #search + '%'"
Dim cmd As OleDbCommand = New OleDbCommand()
cmd.Connection = Con
cmd.CommandType = CommandType.Text
cmd.CommandText = sql
cmd.Parameters.AddWithValue("[account no]", search)
How can I be able to search in my table using only the zone and customer number?

Answer 1

First, you should collect the "zone" and "customer_number" separately (e.g., in separate text boxes). Then you can do a LIKE search using
' test data
Dim zone As String = "125"
Dim customer_number As String = "35"
Using cmd As New OleDbCommand
cmd.Connection = con
cmd.CommandText =
"SELECT * FROM tblCustomer WHERE [account no] LIKE ?"
cmd.Parameters.AddWithValue("?", zone & "-%-" & customer_number)
Using rdr As OleDbDataReader = cmd.ExecuteReader
Do While rdr.Read
Console.WriteLine(rdr("account no"))
Loop
End Using
End Using
