交叉应用自由文本表

Question

MS SQL Server 2005：table1 有全文索引。我想在单个查询中对其运行多个自由文本表搜索，但是我的两次尝试都失败了。任何帮助将不胜感激，谢谢！ps 如果解决了这个问题，我愿意升级到 sql 2008 :)

CREATE FUNCTION fnt_FullTextSearch ( @s NVARCHAR(4000) )
RETURNS TABLE
AS
  RETURN
    ( SELECT [key], [rank]
        FROM FREETEXTTABLE(table1, *, @s) )

DECLARE @terms TABLE ( term VARCHAR(MAX) )
INSERT INTO @terms VALUES ( 'flu' )
INSERT INTO @terms VALUES ( 'acid' )

-- The inline function "..." cannot 
-- take correlated parameters or subqueries 
-- because it uses a full-text operator.
SELECT ft.[key], ft.[rank]
    FROM @terms 
        CROSS APPLY fnt_FullTextSearch(term) ft

--syntax error on term
SELECT ft.[key], ft.[rank]
    FROM @terms 
        CROSS APPLY FREETEXTTABLE(table1, *, term)

Answer 1

也许是因为您缺少第二条语句的别名？

SELECT FT.[key], FT.[rank]
    FROM @terms 
        CROSS APPLY FREETEXTTABLE(table1, *, term) FT

这听起来微不足道......但我看不出它失败的任何其他原因！
