如何在视图上创建全文索引

Question

我想在我的视图上创建全文索引，但我不能，我也看不出问题所在。

我的唯一聚集索引视图：

-- View Creation
CREATE VIEW View_School_Degree WITH SCHEMABINDING AS
    SELECT
        s.Id_School [School Id]
        ,s.Name [School Name]
        ,s.Type
        ,s.Code
        ,CAST(CONCAT(s.Address1, N' ',s.Address2  , N', ', s.Address3, N' ', s.Address4) AS nvarchar(500)) [Postal Address]
        ,s.Email
        ,d.Id_Degree [Degree Id]
        ,d.Title [Degree Title]
        ,d.[Option] [Degree Option]
        ,CAST(CONCAT(d.Code, N' / ', d.[Option]) AS [nvarchar]) [Degree / Option]
        ,sd.Capacity
    FROM dbo.School_Degree sd
    JOIN dbo.School s ON s.Id_School = sd.Id_School
    JOIN dbo.Degree d ON d.Id_Degree = sd.Id_Degree
GO

-- INDEX Creation
CREATE UNIQUE CLUSTERED INDEX [IX_View_School_Degree_Identifier] ON dbo.View_School_Degree
(
    [School Id] ASC,
    [Degree Id] ASC
)

我使用 FULLTEXT 目录创建 FULLTEXT 索引：

CREATE FULLTEXT CATALOG SchoolCatalog
WITH ACCENT_SENSITIVITY = OFF
AUTHORIZATION dbo;
GO

CREATE FULLTEXT INDEX ON dbo.View_School_Degree
(
    [School Name] LANGUAGE 1036
    ,[Degree Title] LANGUAGE 1036
    ,[Postal Address] LANGUAGE 1036
)
KEY INDEX IX_View_School_Degree_Identifier
ON SchoolCatalog
WITH STOPLIST OFF;
GO

我收到这个错误：

'IX_View_School_Degree_Identifier' is not a valid index for applying a full-text search key. A full-text search key must be a unique index that does not accept the value Null, has only one column not offline, is not defined on a calculated non-deterministic or imprecise non-persistent column, has no filter, and has a maximum size of 900 bytes. Choose another index for the full text key

Answer 1

如您在错误消息中所见，这部分内容为：

IX_View_School_Degree_Identifier' is not a valid index .... has only one column

但是您的索引是由两列组成的。您需要创建一个满足这些要求的新索引
