我试图运行此sql语句,但它生成错误"更新附近的语法不正确"

Select Case @location 

        When 'MediaFiles' Then update tblMediaFiles set mdActive=1
        When 'MediaFiles1' Then update tblMediaFiles1 set mdActive=1
        When 'MediaFiles2' Then update tblMediaFiles2 set mdActive=2
        Else update tblMediaFiles4 set mdActive=1

    End

我有问题在Web方法中返回一个列表.这是代码

<WebMethod()> _
Public Function getTags(para_parents As String) As List(Of getTypeDetailsByParentName_Result)()

    Dim context As New PPEntities

    Return context.getTypeDetailsByParentName(para_parents).ToList()

    context.Dispose()

End Function

错误是

类型'System.Collections.Generic.List(Of SaftyonRoad.getTypeDetailsByParentName_Result)'的值无法转换为'System.Collections.Generic.List的一维数组(Of SaftyonRoad.getTypeDetailsByParentName_Result)'
