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)
