Datacontext submitchanges not updating database Nigeria xxx chat
The Northwind Data Context class has properties that represent each Table we modeled within the database (specifically: Products, Categories, Customers, Orders, Order Details).As I covered in Part 3 of this blog series, we can easily use LINQ syntax expressions to query and retrieve data from our database using this Northwind Data Context class. As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late. A good paper is one that people get drawn into because it reaches them ln some way.The properties of each class map to the columns of a corresponding table in the database.
Therefore, the db Data Context cannot track the changes you've made to the object You could try using Data Context.
– Nick Jun 8 at @Nick, BAD idea, and still wouldn't solve your problem, since that way every class gets its own data context.
Your formulation of using also scares me, because that creates even more data contexts. I knew it had something to do with the datacontext.
When we perform queries and retrieve objects like the product instances above, LINQ to SQL will by default keep track of any changes or updates we later make to these objects.
We can make any number of queries and changes we want using a LINQ to SQL Data Context, and these changes will all be tracked together.
