Question

MS SQL Server 2005：table1具有全文索引。我想在一个查询中对它运行多个freetexttable搜索，但是这两次尝试都失败了。任何帮助将不胜感激，谢谢！附：我愿意升级到sql 2008，如果它解决了这个问题：）

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

也许是因为你在第二个语句中缺少别名？

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

这听起来微不足道......但我没有看到任何其他原因导致它失败！

交叉应用FREETEXTTABLE
