Introduction
In this article, I will explain how to insert data into multiple tables using a MySQL Transaction in ASP.NET.
So, let's proceed with the following procedure:
- ASP.NET web page
- Grid View Data Control , MySQL Database and MySQL Transaction
Now, open the MySQLAdmin Page then select "Create a New Table” > "View" >”Table Structure for Table ` student `”.
CREATE TABLE IF NOT EXISTS `student` (
`SID` int(100) NOT NULL AUTO_INCREMENT,
`Name` varchar(100) NOT NULL,
`Address` varchar(500) NOT NULL,
`Email` varchar(100) NOT NULL,
`Mobile` varchar(25) NOT NULL,
PRIMARY KEY (`SID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;
![]()
Table structure for table `courses`
CREATE TABLE IF NOT EXISTS `courses` (
`Course` varchar(100) NOT NULL,
`Name` varchar(100) NOT NULL,
`Amount` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
![]()
Open your instance of Visual Studio 2012 and create a new ASP.NET Web application. Name the project “MySqlTransactionApplication", as shown in the following figure:
![]()
Now design your Student.aspx View design part; use the following code:
Student.aspx
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Student.aspx.cs" Inherits="MySqlTransactionApplication.Student" %>
<asp:Content ID="Content1" ContentPlaceHolderID="titleContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="head" runat="server">
<script type="text/javascript">
function validationCheck() {
var summary = "";
summary += isvalidName();
summary += isvalidAmount();
summary += isvalidAddress();
summary += isvalidEmail();
summary += isvalidMobileno();
if (summary != "") {
alert(summary);
return false;
}
else {
return true;
}
}
function isvalidName() {
var id;
var temp = document.getElementById("<%=txtName.ClientID %>");
id = temp.value;
if (id == "") {
return ("Please Enter Name" + "\n");
}
else {
return "";
}
}
function isvalidAddress() {
var id;
var temp = document.getElementById("<%=txtAddress.ClientID %>");
id = temp.value;
if (id == "") {
return ("Please Enter Address" + "\n");
}
else {
return "";
}
}
function isvalidAmount() {
var id;
var temp = document.getElementById("<%=txtAmount.ClientID %>");
id = temp.value;
if (id == "") {
return ("Please Enter Amount" + "\n");
}
else {
return "";
}
}
function isvalidEmail() {
var id;
var temp = document.getElementById("<%=txtEmail.ClientID %>");
id = temp.value;
var re = /\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/;
if (id == "") {
return ("Please Enter Email" + "\n");
}
else if (re.test(id)) {
return "";
}
else {
return ("Email should be in the form [email protected]" + "\n");
}
}
function isvalidMobileno() {
var id;
var temp = document.getElementById("<%=txtMobile.ClientID %>");
id = temp.value;
var re;
re = /^[0-9]+$/;
var digits = /\d(10)/;
if (id == "") {
return ("Please Enter Mobile no" + "\n");
}
else if (re.test(id)) {
return "";
}
else {
return ("Phone no should be digits only" + "\n");
}
}

}
Now run the page, it will look like the following.
![]()
Now, Student information Enter and Submit, it will look like the following:
![]()
Now, show in the Message box “Student Course Enrollment Successfully”. And show the data to GridViewStudent and GridViewCourses.
![]()
Now, open the MySQLAdmin Page then show the Student and Courses table data
![]()
