I have a DB that has been in use for 8 years. We are changing the data in a couple of fields and I need to update my reporting queries to ensure that they are backwards compatible with the old data.

There are 3 fields in 2 tables:

gen.equity_draw (will be depreciated)

We are shifting our data as follows:

gen.loan_amt >>> custom_data.value
gen.equity_draw >>> gen.loan_amt

My queries work great for selecting individual rows, but I need to also be able to aggregate these upwards and pull sums.

This is what I have for pulling rows of data:

SELECT COUNT(gen.file_id) AS units,
SUM(CASE WHEN (SELECT custom_data.value
FROM custom_data
WHERE custom_data.field = 'und_08' AND custom_data.file_id = gen.file_id) IS NULL
THEN gen.loan_amt
(SELECT custom_data.value
FROM custom_data
WHERE custom_data.field = 'und_08' AND custom_data.file_id = gen.file_id) END) AS maxClaim
FROM gen

What I need is for this query to result is a recordCount (units) and total (maxClaim). Can this be done?

Do you mean this

SELECT COUNT(gen.file_id) AS units, 
SUM(Case When c.field = 'und_08' then c.Value Else gen.loan_amt End) as TotalMaxClaim
FROM custom_data c
left join gen gen on gen.file_id = c.file_id
