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.

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
