Valore proprietà

Tipo: Microsoft.SqlServer.Management.Smo. . :: . .CompatibilityLevel
Valore dell'oggetto CompatibilityLevel che specifica il livello di compatibilità del database.

Implementa

IDatabaseOptions. . :: . .CompatibilityLevel

Osservazioni

This property specifies an earlier version of SQL Server for which certain database actions are to be compatible. This property works like the sp_dbcmptlevel system stored procedure.

Nota

SMO does not support compatibility level 60. If you use SMO with a database set to compatibility level 60, some operations will produce errors. Additionally, if the CompatibilityLevel property for the MSDB database is set to Version70, SMO might throw an exception with a COLLATE error.

Esempi

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")

'Get the current compatibility level.
Dim cl As CompatibilityLevel
cl = db.CompatibilityLevel

'Display the compatibility level of the database.
Console.WriteLine("Compatibility level = " + cl.ToString)

'Set the compatibility level to a different value.
db.CompatibilityLevel = CompatibilityLevel.Version80
db.Alter()

'Restore the compatibility level to original value.
db.CompatibilityLevel = cl
db.Alter()

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")

$cl = New-Object Microsoft.SqlServer.Management.Smo.CompatibilityLevel
$cl = $db.CompatiblityLevel
Write-Host "Compatibility level =" $db.CompatibilityLevel

$db.CompatibilityLevel = [Microsoft.SqlServer.Management.Smo.CompatibilityLevel]'Version80'
$db.Alter()

$db.CompatibilityLevel =
Write-Host "Collation is case-sensitive =" $db.CaseSensitive
