Radgrid not updating after insert

Net AJAX with that of JQuery to give an elegant and charming user experience.column which will act as custom column for delete functionality.Developers using Visual Studio can also use the O/R Designer to implement stored procedure functionality. Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions.The Visual Studio edition that you have and the settings that you use determine these elements. In this task you set up an interface so that users can execute stored procedures to access data in the database.For purposes of this walkthrough, you will use two methods that have been mapped to stored procedures in the Northwind sample database: Cust Orders Detail and Cust Order Hist.The mapping occurs when you run the Sql Metal command-line tool to generate a C# file.show create table foo\G CREATE TABLE `foo` ( `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `u` int(11) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `u` (`u`) ) ENGINE=Inno DB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1 mysql show create table foo\G CREATE TABLE `foo` ( `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `u` int(11) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `u` (`u`) ) ENGINE=Inno DB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1 statements.A lot of the data is duplicate, and it has resulted in one instance of the AI PK increasing from 17,029,941 to 46,271,740 between two rows.

Although both a UNIQUE constraint and a PRIMARY KEY constraint enforce uniqueness, use a UNIQUE constraint instead of a PRIMARY KEY constraint when you want to enforce the uniqueness of a column, or combination of columns, that is not the primary key.

If you try for instance to insert 100 records at a time, with one faulty one, you would get in interactive mode: As you see: No Warnings!

This behavior is even wrongly described in the official Mysql Documentation.

In the applications that you are developing with this walkthrough, users can access data in the database only by using the stored procedures embedded in the application. Note that your contact with the datastore is limited to whatever actions the two stored procedures can take.

Those actions are to return the products included for any order ID you enter, or to return a history of products ordered for any Customer ID you enter.

Multiple UNIQUE constraints can be defined on a table, whereas only one PRIMARY KEY constraint can be defined on a table.
