如果计数的百分比差异小于 1%，则停止包装

Question

我有一个每周运行的程序包，但如果计数差异超过 1%，则需要停止。

这是我获取 2 个计数百分比的查询：

USE MandatedReporting 
DECLARE @a AS float 
DECLARE @b AS float 
declare @c as float 

SET @a = (  SELECT Row_Count 
            FROM [MandatedReporting].[dbo].[DCFS_Weekly_File_Row_Count] WITH(NOLOCK) 
            WHERE TableName = 'MandatedReporting.dbo.MATCH_WEEKLY_V3' 
                  AND RunDate = (   SELECT MAX(RunDate) AS RunDate 
                                    FROM [MandatedReporting].[dbo].[DCFS_Weekly_File_Row_Count] AS ThisWeeksData WITH(NOLOCK) 
                                    WHERE TableName = 'MandatedReporting.dbo.MATCH_WEEKLY_V3')) 

SET @b = (  SELECT Row_Count 
            FROM [MandatedReporting].[dbo].[DCFS_Weekly_File_Row_Count] WITH(NOLOCK) 
            WHERE TableName = 'MandatedReporting.dbo.MATCH_WEEKLY_V3' 
                  AND RunDate = (   SELECT MIN(RunDate) AS RunDate 
                                    FROM [MandatedReporting].[dbo].[DCFS_Weekly_File_Row_Count] AS ThisWeeksData WITH(NOLOCK) 
                                    WHERE TableName = 'MandatedReporting.dbo.MATCH_WEEKLY_V3' 
                                    AND  ABS(DATEDIFF(DD,GETDATE(),CAST(RunDate AS DATETIME))) < 10)) 

set @c = (@a-@b) *100.0/@b SELECT @c as 'Count'

您正在寻找条件拆分。在Execute SQL Task中执行存储过程后，需要将输出存储在一个变量中，然后根据输出实现条件拆分。

只有结束数据流而不是写入文件，否则如果您需要核选项，您可以抛出错误或在存储过程中执行相同操作：

begin
    raiserror('Foo Bar',16,1)
end
