Question

我尝试在我的表上创建一个全文索引，它说我首先需要全文可索引的列。这是什么意思？

我的所有列都是varchar或nvarchar（允许为null）。

这是我遵循的教程：

我无法说出你做错了什么和哪里。

首先转到您的服务，看看您是否安装了全文服务，如果已安装，请确保它是Running。

一旦你确认了它，就会在那里运行，你可以按照以下步骤在表格上创建一个FTS索引

/*A Table with A Primary key Defined on a column*/

CREATE TABLE Test_FTS 
(ID INT PRIMARY KEY NOT NULL
,Column1 NVARCHAR(100)
,Column2 VARCHAR(100))
GO

/*
Your Table have to have a PRIMARY KEY  or atleast a Unique Index defined on any 
column in your table.

Basicaly this Unique Index/Primary Key value will be stored in your FTS
working as a POINTER to the data in your table. 
*/

 /* Only create a Unique Index if you do not have a Primary Key in your table*/
CREATE UNIQUE INDEX UIX_SomeUniqueIdex ON dbo.Test_FTS(ID);
GO

/*Create a Catalog*/
CREATE FULLTEXT CATALOG FTS_Test_Catalog AS DEFAULT;
GO

/* Finally the FTS Index */
CREATE FULLTEXT INDEX ON Test_FTS (Column1) 
   KEY INDEX UIX_SomeUniqueIdex;
GO

使列与全文索引兼容
