Hi my data is as follows:
Oppo_OpportunityId Oppo_Stage Oppo_CreatedDate ranking
248072 QUOTED 2015-12-01 07:58:18.000 1

248072 QUOTED 2016-07-26 10:41:39.000 12
How do I in sql server read each of these records and then get the difference in the datetime values. For example,
QUOTING 2016-07-22 07:16:22.000 next record QUOTED 2016-07-26 10:30:25.000; the difference as a value to appear by the first record - hope this makes sense. I have the code to get the difference just unsure how to code this, thought of using ROW_NUMBER().
Hope someone can help me
