Question

I have a table with an JobID (PK), EmployeeID (FK), StartDate, EndDate containing data such as:

1, 10, '01-Jan-2010 08:00:00', '01-Jan-2010 08:30:00'
2, 10, '01-Jan-2010 08:50:00', '01-Jan-2010 09:05:00'
3, 10, '02-Feb-2010 10:00:00', '02-Feb-2010 10:30:00'

I want to return a record for each EndDate for a Job and then the same employees StartDate for his next immediate job (by date time). So from the data above the result would be

Result 1: 10, 01-Jan-2010 08:30:00, 01-Jan-2010 08:50:00
Result 2: 10, 01-Jan-2010 09:05:00, 02-Feb-2010 10:00:00

Greatly appreciate any help!

Lance’s code has a problem. Here is the corrected query that will work:

select j1.JobID, j1.EmployeeID, j1.EndDate, 
(
    select top 1 j2.StartDate 
      from Job j2
     where j2.EmployeeID = j1.EmployeeID
       and j2.StartDate > j1.EndDate
     order by j2.StartDate
) as NextStartDate
from Job j1
