带有list searchkey

Question

它看起来像FREETEXTTABLE只允许searchkey参数作为变量，如下所示：

FROM FREETEXTTABLE(dbo.SampleTable, SampleColumn, @searchKey)

我有一个列表searchKey值，大约50000条记录，如何＆＃34;加入＆＃34;带有FREETEXTTABLE的searchKey表

我已经使用了WHILE，但它很慢

DECLARE @results as table(
    Key NVARCHAR(100),
    Rank INT
)

declare @numberOfRows INT = SELECT MAX(Id) FROM dbo.SearchKeyTable)
declare @step int = (SELECT MIN(Id) FROM dbo.SearchKeyTable)

WHILE (@step <= @numberOfRows)
BEGIN
    declare @searchKey NVARCHAR(500) = (Select TOP(1) '''' + REPLACE([Description], '''', '"')  + ''' OR ''' + REPLACE([itemname], '''', '"') + '''' From dbo.SearchKeyTable where id = @step ORDER BY Id)

    insert into @results
    select [Key] as KeyId, SUM([Rank]) as TotalRank FROM FREETEXTTABLE(dbo.SampleTable, SampleColumn, @searchKey) GROUP BY [Key]

    SET @step = @step + 1
END

select * from @results

我的dbo.SampleTable表也很大，约有1600万条记录

当前解决方案：使用c＃多线程替换WHILE
