I am not expert in MySQL so you please google and put appropriate function at placed by $ in following query. select t1.Inserted_date ,timediff($) -- take time from t1.Inserted_date and t2.Inserted_date from TBL_TRN_RESOURCE_UTILIZATION t1 left outer join TBL_TRN_RESOURCE_UTILIZATION t2 on t1.utilization_id = t2.utilization_id + 1

You can create an "AFTER INSERT" trigger on this table's inserted_date column, in that trigger you can find the current id and from current id you can find last id by doing minus 1 on id, then you can compare both dates, find difference and update the column Duration

Use self join. Can you not share bit more details? Table name, columns, key columns, what is the basis of identifying how set of records group together. We cannot imagine your table structure....
