select 在 sp 中查询 returns 为空，但当运行单独查询时，它不是空的。为什么？

Question

我有一个写入 Table 并读取 table 的存储过程。我写没有问题，但是当我想阅读它时 returns 是空的。但是当我 select 查询并且运行它 returns 数据时它不是空的。为什么可以。这是我的代码。我将全文索引 Dump 和 TempTable 赋给标签、标题和 body 列。

    IF LEFT(@splitdata,1) = '#'
    BEGIN
        SET @splitdata = (SELECT REPLACE(@splitdata,'#',''))

        INSERT INTO [WebTR].[dbo].[TempTable]
                SELECT p.*
                FROM [WebTR].[dbo].[Dump] AS p 
                    INNER JOIN containstable([WebTR].[dbo].[Dump], tags, @splitdata) AS k
                    ON p.dumpID = k.[key]
    end

    SET @replacedLast += @replaced2
    FETCH NEXT FROM TableA_cursor INTO @row

我先插入温度table然后

IF EXISTS(SELECT * FROM WebTR.dbo.TempTable)

BEGIN

SELECT @replacedLast AS withtag

    select dumpId,title,source,tags,creationdate,status,body,createdBy,max(rank) as rank,'olsanaaa' AS sinir
    from
    ((SELECT p.*, k.rank
    FROM WebTR.dbo.TempTable AS p
        INNER JOIN containstable(WebTR.dbo.TempTable, title,'"*cunku*"' ) AS k
        ON p.dumpID = k.[key]
        )
    union
    (
    SELECT p.*, k.rank
    FROM WebTR.dbo.TempTable AS p
        INNER JOIN containstable(WebTR.dbo.TempTable, body, '"*cunku*"') AS k
        ON p.dumpID = k.[key]

        ))y group by dumpId,title,source,tags,creationdate,status,body,createdBy
    order by rank DESC


END

正如你所看到的那样，当我 select 仅 select 查询它 returns 数据时，如果阻塞，但是当执行存储过程时，它 returns 为空，即使它进入如果块

Answer 1

我在 SQL Server 2008 中也有这种不当行为。如果您使用全文索引插入和检索速度太快，您的查询将不会生成新查询。

也许您需要手动填充全文索引。

查看基于 AdventureWorks 的示例

ALTER FULLTEXT INDEX ON HumanResources.JobCandidate START UPDATE POPULATION;
GO

希望人口更新能解决您的问题。
