带有列表搜索键的 Sql FREETEXTTABLE

Question

它看起来是自由文本表，只允许搜索键参数作为变量，如下所示：

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

我有一个列表搜索键值，大约 50000 条记录，如何使用 FREETEXTTABLE "加入"搜索键表

我用过 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。采样表也很大，约1600万条记录
