ADO.NET Tutorial - Updating Data

This page provides a basic introduction to the UpdateData feature in ADO.NET.

Introduction

The UpdateData feature in ADO.NET allows you to modify existing data in a database table. This is often useful for data correction or synchronization.

Key Concepts

Data Source: The table you want to update.
UpdateData: The method used to modify the data.
Row Update: The specific field being modified.

Updating a Specific Field

Let's illustrate with an example:

                Data:
                Original:                      Value:
                                            Value:
                    
                    New:                         Value:
                                                    Value:
                        
                    
                
                Modified:                     Value:
                                            Value:
                    
                
            

            You can use the `UpdateData` method to perform these updates.

Example Usage

Let's assume we have a table called 'Customers' with columns like 'CustomerID', 'Name', 'City', and 'Age'.

We want to update the 'Age' field for a specific customer.

                Original:
                CustomerID:
                Name:
                City:
                Age:
                Value:

Update: CustomerID: Name: City: Age: Value:
