Question

I have 3 columns in a table in my database – Created, Expires and Expiration_Interval. Both Created and Expires are datetimeoffset(0) and Expiration_Interval is of data type Time(0).

Created gets populated with SYSUTCDATETIME(), when inserting a new row. Data for Expiration_Interval is provided in the input XML in hh:mm:ss format, extracted and populated. The requirement is to populate Expires column with Created+Expiration_Interval. Here is my approach:

  INSERT INTO SESSIONS
  SELECT 
    Expiration_Interval,
    SYSUTCDATETIME(),
    DATEADD(s,((DATEPART(hh,Timeout)*3600)+(DATEPART(mi,Timeout)*60)+    DATEPART(ss,Timeout)),SYSUTCDATETIME())
  FROM input_xml -- CTE with shredded XML data

Is there an easier way to do this? This is on SQL Server 2008 R2

Answer 1

You can cast Timeout to datetime and use + to add time to SYSUTCDATETIME().

SYSUTCDATETIME()+cast(Timeout as datetime)
