sql - 在 View 上创建全文索引时出现问题

Question

我有一个像这样创建的 View :

CREATE VIEW [dbo].[vwData] WITH SCHEMABINDING
AS
    SELECT  [DataField1] ,
            [DataField2] ,
            [DataField3]
    FROM    dbo.tblData

当我尝试在其上创建全文索引时，如下所示:

CREATE FULLTEXT INDEX ON [dbo].[vwData](
[DataField] LANGUAGE [English])
KEY INDEX [idx_DataField]ON ([ft_cat_Server], FILEGROUP [PRIMARY])
WITH (CHANGE_TRACKING = AUTO, STOPLIST = SYSTEM)

我收到此错误:

View 'dbo.vwData' is not an indexed view. 
Full-text index is not allowed to be created on it.

知道为什么吗？

首先，您需要在 View 上创建唯一的聚集索引，然后再创建全文索引。

假设你有一张 table :

CREATE TABLE [dbo].[tblData](
    [DataField1] [Varchar] NOT NULL,
    [DataField2] [varchar](10) NULL,
    [DataField3] [varchar](10) NULL
    )

正如您已经所做的那样，您有一个 View :

CREATE VIEW [dbo].[vwData] 
WITH SCHEMABINDING
AS
    SELECT  [DataField1] ,
            [DataField2] ,
            [DataField3]
    FROM    dbo.tblData
GO

现在您需要在 View 上创建唯一的聚集索引:

CREATE UNIQUE CLUSTERED INDEX idx_DataField
    ON [dbo].[vwData] (DataField1);
GO

由于您已有全文目录ft_cat_Server，创建唯一键后，您可以创建全文索引:

CREATE FULLTEXT INDEX ON [dbo].[vwData](
[DataField1] LANGUAGE [English])
KEY INDEX [idx_DataField]ON ([ft_cat_Server], FILEGROUP [PRIMARY])
WITH (CHANGE_TRACKING = AUTO, STOPLIST = SYSTEM)

希望这有帮助:)
