Question

I have a table of data. I have a field which shows date. I had set this column as Start Date. I want to create an additional column as End Date, where the End Date will be the Start Date of the next row. Can you give me a query of creating the End Date by taking the data of the Start Date in next row ?

Answer 1

Assuming you already have your columns and that you have an Auto-Incrementing Primary Key:

Update T1
Set T1.EndDate = T2.StartDate
From [Table] T1
Inner Join [Table] T2 on T1.Id = T2.Id - 1
