Question

我想在视图上创建FULLTEXT索引，但我不能，也看不出问题所在。

具有唯一聚集索引的视图：

-- 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
)

使用FULLTEXT目录创建我的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

我收到此错误：

“ IX_View_School_Degree_Identifier”不是用于应用全文本搜索键的有效索引。全文搜索关键字必须是唯一的索引，不接受Null值，只有一列不脱机，没有在计算得出的不确定性或不精确的非持久性列上定义，没有过滤器，并且最大值900个字节的大小。为全文键选择另一个索引

Answer 1

您会在错误消息中看到，该部分显示：

IX_View_School_Degree_Identifier'不是有效的索引....只有一列

但是，您的索引由两列组成。您需要创建一个满足这些要求的新索引
