Osservazioni

Use the ApplicationDatabaseOptions class to configure the default filegroup and collation for the application database.

Specifying application database properties is optional. For more information about default values, see Definizione del database dell'applicazione.

If you want to alter the application database after creating the application, use the SQL Server tools, such as SQL Server Management Studio.

Esempio

The following examples show how to define application database options:

// Create ApplicationDatabaseOptions object
ApplicationDatabaseOptions adb = 
    new ApplicationDatabaseOptions(myApplication, "MyAppDB");

// Define and add a filegroup
ApplicationDatabaseFileGroup adb_fg = 
    new ApplicationDatabaseFileGroup(adb, "PRIMARY");
adb.ApplicationDatabaseFileGroups.Add(adb_fg);

// Define and add a database file
ApplicationDatabaseFile adb_file1 = 
    new ApplicationDatabaseFile(adb_fg, "MyApp_PrimaryFile1");
adb_file1.FileName = @"C:\NS\Full\MyApp_PrimaryFile1.mdf";
adb_file1.InitialSize = "10MB";
adb_file1.MaxSize = "50MB";
adb_file1.GrowthIncrement = "10%";
adb_fg.ApplicationDatabaseFiles.Add(adb_file1);

// Define and add a log file
ApplicationDatabaseLogFile adb_log = 
    new ApplicationDatabaseLogFile(adb, "MyApp_LogFile1");
adb_log.FileName = @"C:\NS\Full\MyApp_LogFile1.ldf";
adb_log.InitialSize = "5MB";
adb_log.MaxSize = "20MB";
adb_log.GrowthIncrement = "10%";
adb.ApplicationDatabaseLogFiles.Add(adb_log);


// Define database options
adb.CollationName = "Latin1_General_CS_AS";
adb.DefaultFileGroup = "PRIMARY";

// Assign options to ApplicationDatabaseOptions property
myApplication.ApplicationDatabaseOptions = adb;

' Create ApplicationDatabaseOptions object
Dim adb As ApplicationDatabaseOptions = _
    New ApplicationDatabaseOptions(myApplication, "MyAppDB")

' Define and add a filegroup
Dim adb_fg As ApplicationDatabaseFileGroup = _
    New ApplicationDatabaseFileGroup(adb, "PRIMARY")
adb.ApplicationDatabaseFileGroups.Add(adb_fg)

' Define and add a database file
Dim adb_file1 As ApplicationDatabaseFile = _
    New ApplicationDatabaseFile(adb_fg, "MyApp_PrimaryFile1")
adb_file1.FileName = "C:\NS\Full\MyApp_PrimaryFile1.mdf"
adb_file1.InitialSize = "10MB"
adb_file1.MaxSize = "50MB"
adb_file1.GrowthIncrement = "10%"
adb_fg.ApplicationDatabaseFiles.Add(adb_file1)

' Define and add a log file
Dim adb_log As ApplicationDatabaseLogFile = _
    New ApplicationDatabaseLogFile(adb, "MyApp_LogFile1")
adb_log.FileName = "C:\NS\Full\MyApp_LogFile1.ldf"
adb_log.InitialSize = "5MB"
adb_log.MaxSize = "20MB"
adb_log.GrowthIncrement = "10%"
adb.ApplicationDatabaseLogFiles.Add(adb_log)

' Define database options.
adb.CollationName = "Latin1_General_CS_AS"
adb.DefaultFileGroup = "PRIMARY"

' Assign options to the ApplicationDatabaseOptions property.
myApplication.ApplicationDatabaseOptions = adb
