触发基于报告的数据输入

Question

我正在使用MS SQL Server 2008R2 标准版。我正在寻找基于某个表的最终值的最终条目来触发报告。该报告是使用SQL Server Business Intelligence Development studio 设计的。

是否可以在不使用数据驱动订阅的情况下做到这一点。数据驱动订阅是MS SQL Server 2008R2 标准版中缺少的一项功能。

我有一个部分解决方案

CREATE TRIGGER tr_Report_INSERT_PHASE_PROC

ON [database].[dbo].[table] 
AFTER INSERT 
AS 
IF EXISTS (SELECT * FROM [database].[dbo].[table] where process_value = 'End Of BATCH' )
BEGIN 

    EXEC ReportServer.dbo.AddEvent @EventType='TimedSubscription',

    @EventData='xxxx' -- SubscriptionID from Report Manager URL 
END 
go

但这会在每次插入时触发，并且我的表具有历史 process_value = 'End of Batch'。所以我需要在我的条件中添加一个 AND if serial_no = inserted serial_no。

如何找到插入的序列号的值？

Answer 1

我会在名为“已处理”的表中添加一个位列。然后将程序更新为：

CREATE TRIGGER tr_Report_INSERT_PHASE_PROC
ON [database].[dbo].[table] 
AFTER INSERT 
AS 
IF EXISTS (
           SELECT * 
           FROM [database].[dbo].[table] 
           WHERE process_value = 'End Of BATCH' 
                AND processed = 0 -- Only process if there is an unprocessed record
          )
BEGIN 

    EXEC ReportServer.dbo.AddEvent @EventType='TimedSubscription',
    @EventData='xxxx' -- SubscriptionID from Report Manager URL 

    -- Mark record as processed
    UPDATE [database].[dbo].[table] 
    SET processed = 1 
    WHERE process_value = 'End Of BATCH' 
         AND processed = 0

END 
go
