I have simple tbl_posts table with three c开发者_如何学编程olumns (id, name, content)
I created fulltext index for name and content columns. When I query it like:
SELECT *
FROM dbo.tbl_posts
WHERE FREETEXT ( *, 'search word' )
I want that the order for results will be ordered first by rank in column name and then my content
CREATE FUNCTION PostFreeTextSearch
(
@SearchTerms nvarchar(100)
)
RETURNS TABLE
AS
RETURN
(
SELECT
CASE WHEN fttName.[Key] IS NULL THEN fttContent.[Key] ELSE fttName.[Key] END as id,
fttName.[RANK] as NameScore,
fttContent.[RANK] as ContentScore
FROM
FREETEXTTABLE(tbl_Posts, (Name), @SearchTerms) fttName
FULL OUTER JOIN
FREETEXTTABLE(tbl_Posts, (Content), @SearchTerms) fttContent ON fttName.[Key] = fttContent.[Key]
WHERE fttName.RANK > 0 OR fttContent.RANK > 0
)
GO
SELECT * FROM PostFreeTextSearch('sql server')
