通过查询索引名称创建全文索引

Question

我想创建一个全文索引，但我不确定索引名称是否在所有数据库中都是相同的。所以，我打算写下面的选择并获取索引的名称。

DECLARE @keyIndex NVARCHAR(100) 
SELECT @keyIndex = name FROM sysobjects WHERE xtype = 'PK' AND parent_obj = OBJECT_ID(N'[dbo].[Table1]') 

以下是全文索引创建语句，我曾尝试：

CREATE FULLTEXT INDEX ON dbo.Table1 
    (
     [Name] Language 1033, 
     [Description] Language 1033 
    ) 
    KEY INDEX [@keyIndex] 
    WITH STOPLIST = SYSTEM, CHANGE_TRACKING AUTO; 

它给出了这样的错误：

Msg 7653, Level 16, State 1, Line 11 
'@keyIndex' is not a valid index to enforce a full-text search key. A full-text search key must be a unique, non-nullable, single-column index which is not offline, is not defined on a non-deterministic or imprecise nonpersisted computed column, does not have a filter, and has maximum size of 900 bytes. Choose another index for the full-text key. 

我需要如何动态地插入一些帮助关键指标值。

只是手动生成字符串，然后执行它：

DECLARE @SQLString nvarchar(1000) 
DECLARE @ParmDefinition nvarchar(1000) 
DECLARE @keyIndex nvarchar(100); 
set @keyIndex = 'Id' 
SET @SQLString = 
    N'CREATE FULLTEXT INDEX ON dbo.objects 
    (
     [Name] Language 1033, 
     [Description] Language 1033 
    ) 
    KEY INDEX ' + @keyIndex +N' 
    WITH STOPLIST = SYSTEM, CHANGE_TRACKING AUTO;'; 
EXEC(@SQLString)
