• Right-click App_Data in the Solution Explorer window Folder
• SelectAdd, New Item
• SelectSQL Server Compact Local Database *
• Name the database Click the Add button for
Movies.sdf

* if there is no SQL Server Compact Local Database in the options , you have not installed SQL Server Compac on your computer. Please install via the following link: SQL Server Compact

Visual Web Developer automatically creates the database in the App_Data folder.

Add database table

Double-click the Movies.sdf file in the App_Data folder and Database Explorer## will open # window.

To create a new table in the database, right-click the

Tables folder and select Create Table.

Create the following columns:

##ColumnID##Titlenvarchar(100)NoDirectornvarchar(100)NoDatedatetimeNo

Explanation of columns:

ID is an integer (full number) used to identify each record in the table.

Title is a 100-character text column that stores the title of the movie.

Director is a 100-character text column that stores the director's name.

Date is the date column used to store the release date of the movie.

After creating the above columns, you must set the ID column as the primary key (record identifier) ​​of the table. To do this, click on the column name (ID) and select Primary Key. In the Column Properties window, set the Identity property to True:

When you create the table After the columns, save the table and name it MovieDBs.

Note:

We intentionally named the table "MovieDBs" (ending with s). In the next chapter, you will see "MovieDB" for the data model. This may seem a bit strange, but this naming convention ensures that the controller is connected to the database table, and you must use it.
