ช่วยดู Code Sql ให้หน่อยค่ะ ไม่เข้าใจว่า Arguments : an_brchid มันคืออะไรค่ะ

strSQL = "INSERT INTO customer (CustomerID,Name,Email,CountryCode,Budget,Used) " & _
"VALUES (:sCustomerID,:sName,:sEmail,:sCountryCode,:sBudget,:sUsed)"

objCmd = New System.Data.OracleClient.OracleCommand(strSQL,objConn)
With objCmd
.Parameters.Add(new OracleParameter(":sCustomerID", "C005"))
.Parameters.Add(new OracleParameter(":sName", "Weerachai Nukitram"))
.Parameters.Add(new OracleParameter(":sEmail", "[email protected]"))
.Parameters.Add(new OracleParameter(":sCountryCode", "TH"))
.Parameters.Add(new OracleParameter(":sBudget", "2000000"))
.Parameters.Add(new OracleParameter(":sUsed", "100000"))
End With
