croatian dating personals - Updating data using linq to sql

You can see this best when I create the record, to show that LINQ-to-SQL will automatically query this value after it has inserted the record and pop it onto the object. The other cool feature here is that the order of the SQL statements is decided for you to ensure that all of the keys can be correctly set without tripping up the constraints along the way.

Update statements are even simpler, again keeping with the mindset of working with objects we simply get an object representing a row, changes it properties and save it back.

Here we will learn LINQ to SQL insert, update delete operations in c#, with examples or how to perform crud (insert, update, delete) operations in LINQ to SQL using c#, with examples.

This is how we can use LINQ to SQL to perform insert, update, delete and select operations in c#,

I would probably pass in the customer log as a parameter to the method and then have it deal with just the database insertion.

Module Module1 Sub Main() Dim connect String As String = System.

Write Line("Employee Id = , Name = , Email = , Contact No = , Address = ", inserted Employee.

If you wanted to keep a Insert Or Update type of approach I would branch on perhaps something like the object ID if it has one.

This way you can have a variety of ways that your object is created and the method is only responsible for the persistance of that object not also it's creation and populating.

Submit Changes() Dim updated Employee As Employee = db.

Write Line("Employee Id = , Name = , Email = , Contact No = , Address = ", updated Employee.

Read Key() End Sub End Module Module Module1 Sub Main() Dim connect String As String = System.
