Calculate sum if field exists

I need to update my load script to perform the following.  I have two fields one which is always assigned to a record (Time) and a second field (compressedTime) which could exist on the record. 

1)  Check if a field exists (compressedTime) on the record and calculate the sum. 

2)  If the field DOES NOT exist on the record then calculate the sum of another field (Time). 

3)  Sum of the two fields based on the above criteria.

Try:

If(ISNULL(compressedTime), Time, compressedTime) AS CurrectTime


AND then you can sum the calculated field (CurrectTime).

In both fields - is the non exists values defined as NULL?

Unfortunately no - we use a non-relational DB, so the field either exists on the record or not.  We don't insert this field on every record and then assign a NULL value if empty.

I can't understand your data structure, are the fields in different tables?

Can you please share your original table so I can help more?

All the fields are in the same table.

I think this is what you want.  If the compressed time is there you want to sum record time and compressed time otherwise just sum the record time.

TimeProblem:

load * Inline [

rtime, compressedTime

02:35:00, 01:30:00

10:00:00,

03:30:30, 00:15:00

04:45:00, 02:20:00
