Question

我有一个存储过程，我写入Table并读取表。我写没有问题但是当我想读它时它返回空。但是当我选择查询并运行它返回数据时它不是空的。为什么会这样。这是我的代码。我将全文索引转储和TempTable提供给标签，标题和正文列。

    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

我首先插入temptable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if if当我只选择select查询时它返回数据但是当执行存储过程时它返回空，即使它进入if块

Answer 1

我在SQL Server 2008中也有这种不当行为。如果使用全文索引插入和检索太快，则查询将不会产生新查询。

也许您需要手动填充全文索引。

参见基于AdventureWorks的示例

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

希望人口更新将解决您的问题。

祝你好运，离子

Answer 2

CLOSE TableA_cursor
DEALLOCATE TableA_cursor

你检查过这部分了吗？因为光标在某些操作之前正在关闭。

select查询在sp中返回空，但单独运行时，它不为空。为什么？
