我想从此查询中获取ExtractedDate的值,并在下一个查询中将其用作@LastExtractDate。
我怎么做?
SELECT TOP 1 [ExtractedDate]
FROM [OnsiteV4].[dbo].[SqlPendingIndex] order by ExtractedDate desc
下一个查询:
insert into @table(Hex, KeyDeviceId, ObjectDateTime, ExtractedDate )
SELECT CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), ObjectValue, 1)) AS Hex, KeyDeviceId, ObjectDateTime , GETDATE ()
FROM SQLPending
WHERE (ObjectSubType LIKE '%GAS%') and (ObjectDateTime > @LastExtractDate)
最佳答案
为什么不使用这个:
declare @LastExtractDate date
SELECT TOP 1 @LastExtractDate=[ExtractedDate]
FROM [OnsiteV4].[dbo].[SqlPendingIndex] order by ExtractedDate desc
