Public Property CompatibilityLevel As CompatibilityLevel

Property Value

Type: Microsoft.SqlServer.Management.Smo.CompatibilityLevel

A CompatibilityLevel object value that specifies the compatibility level of the database.

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.


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.

'Reference the AdventureWorks2012 database.
Dim db As Database

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

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