Question

我有一个选择存储过程，我正在努力使它所带来的结果也会更新一个名为Downloaded的列，并将这些行标记为下载。

例如，我将那10行中的10行下拉，我还希望在同一存储过程中将Downloaded列更新为true。这可能吗？

到目前为止，这是我的sp，它会下载数据。

ALTER PROCEDURE [dbo].[GetLeads]
@DateTo datetime = null,
@DateFrom datetime = null
AS
    SELECT name
         , lastname
         , title
         , company
         , address
         , address2
         , city
         , [state]
         , zip
         , country
         , stamptime

    FROM
        lead
    where
         ((@DateTo is null AND @DateFrom IS null) or (stamptime BETWEEN @DateTo AND @DateFrom))

谢谢！

Answer 1

您只需OUTPUT更新的行;

UPDATE lead
  SET Downloaded = 1
OUTPUT INSERTED.* 
  WHERE ((@DateTo is null AND @DateFrom IS null) or (stamptime BETWEEN @DateTo AND @DateFrom))

此更新，然后在单个语句中返回更新的行。

继续关注vulkanino的评论答案，如下：

ALTER PROCEDURE [dbo].[GetLeads]
@DateTo datetime = null,
@DateFrom datetime = null
AS
    UPDATE  
        lead 
    SET     
        Downloaded = 1 
    WHERE   
        ((@DateTo is null AND @DateFrom IS null) or (stamptime BETWEEN @DateTo AND @DateFrom))

    SELECT name
         , lastname
         , title
         , company
         , address
         , address2
         , city
         , [state]
         , zip
         , country
         , stamptime

    FROM
        lead
    where
         ((@DateTo is null AND @DateFrom IS null) or (stamptime BETWEEN @DateTo AND @DateFrom))

Answer 3

您最好的选择可能是使用带UPDATE的OUTPUT语句。

http://blog.sqlauthority.com/2007/10/01/sql-server-2005-output-clause-example-and-explanation-with-insert-update-delete/

DECLARE @TEMPTABLE
(
    name <type>
    , lastname <type>
    , title <type>
    , company <type>
    , address <type>
    , address2 <type>
    , city <type>
    , state <type>
    , zip <type>
    , country <type>
    , stamptime <type>
)

UPDATE a
SET a.Downloaded = 1
OUTPUT Inserted.name, Inserted.lastname, Inserted.title, etc. INTO @TEMPTABLE
FROM lead a
WHERE ((@DateTo IS NULL AND @DateFrom IS NULL) OR (a.stamptime BETWEEN @DateTo AND @DateFrom))

SELECT * FROM @TEMPTABLE

在一个存储过程中选择并更新
