Question

如果我只传递一个字母作为参数

，则全文搜索无效

DECLARE @search_param NVARCHAR(250)
SET @search_param = 'a'

    SELECT TOP 500
             [KEY] AS id,
             [RANK] AS relevance
    FROM     CONTAINSTABLE(table_name, column_name, @search_word)
    ORDER BY 2 DESC, 1 desc

如果只传递一个字母，我需要它只选择以该字母开头的句子。

Answer 1

使用'a *'搜索“以”开头“

DECLARE @search_param NVARCHAR(250) SET @search_param = 'a'

-- if only one letter is passed
-- i need it to select only sentences that start with that letter
if len(@search_param) = 1 set @search_param = '"' + @search_param + '*"'

SELECT TOP 500
         [KEY] AS id,
         [RANK] AS relevance
FROM     CONTAINSTABLE(table_name, column_name, @search_param)
ORDER BY 2 DESC, 1 desc

SQL Server 2008全文搜索不使用一个字母
