IsValid (Command Interface)
[!附註]
下一版的 Microsoft SQL Server 將不再提供此功能。請勿在新的開發工作中使用此功能，並且儘速修改使用此功能的應用程式。
The IsValid property of the Command interface indicates whether the Name and Statement properties are empty and whether the command object belongs to a collection.
Applies To:clsCubeCommand, clsDatabaseCommand, clsRoleCommand
Data Type
Boolean
Access
Read-only
備註
Because of the flexible nature of command objects, only the following checks are performed:
The Name property of the command object is not empty.
The Command object belongs to a Commands collection.
The Statement property of the command object is not empty.
Executing a command is the only way to determine whether the command functions correctly.
範例
Use the following code to return the validity status of a command object:
'Assume a command object (dsoCmd) exists.
If dsoCmd.IsValid Then
'Insert code to save the command.
Else
'Return an error with one or more properties.
End If
