我的桌子是这样的：

    CREATE TABLE [dbo].[ClosedTaskCustomFields](
    [ClosedTaskId] [uniqueidentifier] NOT NULL,

    [Value] [nvarchar](450) NULL
    ... 
 CONSTRAINT [PK_ClosedTaskCustomFields] PRIMARY KEY CLUSTERED 
(
    [ClosedTaskId] ASC,
    [CustomFieldId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

CREATE NONCLUSTERED INDEX [IX_ClosedTaskCustomFields_ClosedTaskId] ON [dbo].[ClosedTaskCustomFields]
(
    [ClosedTaskId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, …
