How can I combine the following into one SQL statement? The problem I am having is the majority of the data is coming from one table, but the criteria for each field is different.

SELECT SUM(nloan_amount) as Total_Amt_CAP_Loans FROM loan.dbf WHERE UPPER(cstatus) = "ENROLLED" OR UPPER(cstatus) = "LOSS" OR UPPER(cstatus) = "PIF"

SELECT SUM(nloan_amount) as Total_Amt_Enrolled_Loans FROM loan.dbf WHERE UPPER(cstatus) = "ENROLLED"

SELECT SUM(nstate_reserve_payment) as nBDC_Reserve FROM loan.dbf WHERE UPPER(cstatus) = "ENROLLED" OR UPPER(cstatus) = "LOSS" OR UPPER(cstatus) = "PIF"

SELECT SUM(nborrower_reserve_payment) + SUM(nlender_reserve_payment) as nBank_Borrower_Reserve FROM loan.dbf WHERE UPPER(cstatus) = "ENROLLED" OR UPPER(cstatus) = "LOSS" OR UPPER(cstatus) = "PIF"

SELECT SUM(ytotal_claim_amount) as nClaims_Paid FROM claims.dbf
