IsValid (Command Interface)

注意注意

  下一版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。

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

注释

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.

示例

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
