需要varchar參數的SQL Server存儲過程未按預期工作

Question

我對SQL還是很陌生，所以請原諒任何無知的問題。

這是我的存儲過程：

ALTER PROCEDURE [dbo].[search_highlights]
    @page INT = 1,
    @recsPerPage INT = 20,
    @query NVARCHAR(MAX) = ''
AS
BEGIN
    SET NOCOUNT ON

    DECLARE @FirstRec AS INT = (@page - 1) * @recsPerPage,
            @LastRec AS INT = (@page * @recsPerPage + 1)

    SELECT
        [id],
        [datetime],
        [player_ids], [player_names],
        [headline], [duration],
        [blurb], [bigblurb],
        [thumb_s], [thumb_m], [thumb_l],
        [video_s], [video_m], [video_l],
        [gameid],
        [team_id], [team_name]
    FROM 
        (SELECT
             [id],
             [datetime],
             [player_ids], [player_names],
             [headline],
             [duration],
             [blurb], [bigblurb],
             [thumb_s], [thumb_m], [thumb_l],
             [video_s], [video_m], [video_l],
             [gameid],
             [team_id], [team_name],
             ROW_NUMBER() OVER (ORDER BY datetime DESC) AS rn
         FROM 
             [bbt].[dbo].[highlights]
         WHERE 
             CONTAINS((player_names, headline, blurb, bigblurb, team_name), @query)
        ) hp
    WHERE 
        rn BETWEEN @FirstRec AND @LastRec
    ORDER BY 
        datetime DESC
END

我試圖像這樣調用存儲過程：

EXEC [dbo].[search_highlights] 1, 20, '"double play"'

運行該命令時，出現以下錯誤：

消息7630，級別15，狀態2，過程dbo.search_highlights，第13行[批處理開始第0行]
在全文搜索條件“””中，“”附近的語法錯誤。

當我嘗試不帶" ，錯誤消失了，但是即使我應該得到結果，也沒有得到結果。

救命？

在SQL Server中，您需要定義字符串的長度（在大多數情況下，默認值是1）。

因此，將存儲過程定義為：

ALTER PROCEDURE [dbo].[search_highlights] (
    @page int = 1,
    @recsPerPage int = 20,
    @query VARCHAR(max) = ''
) AS . . .
