Valeur de propriété

Type : Microsoft.SqlServer.Management.Smo.CompatibilityLevel
A CompatibilityLevel object value that specifies the compatibility level of the database.

Implémente

IDatabaseOptions.CompatibilityLevel

Notes

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.

[!REMARQUE]

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.

Exemples

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

'Reference the AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")

'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("AdventureWorks2012")

$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
