用以下方法解决:
注: 下面的table_name是你建full text search所在的表名(代码无需修改).只要打开相应的数据库执行以下查询代码即可
IF EXISTS (SELECT * FROM sys.fulltext_indexes fti WHERE fti.object_id = OBJECT_ID(N'[dbo].[table_name]'))
ALTER FULLTEXT INDEX ON [dbo].[table_name] DISABLE
GO
IF EXISTS (SELECT * FROM sys.fulltext_indexes fti WHERE fti.object_id = OBJECT_ID(N'[dbo].[table_name]'))
DROP FULLTEXT INDEX ON [dbo].[table_name]
GO
IF EXISTS (SELECT * FROM sysfulltextcatalogs ftc WHERE ftc.name = N'table_name')
DROP FULLTEXT CATALOG [table_name]
