                                select asv.AllowedAmount;

Sample SQL¶

Inferred SQL: This SQL was inferred from the LINQ statement above and the NHibernate mappings. It is not concrete SQL from source code; NHibernate generates the executed statement at runtime, so aliases, column order, join syntax, and bind-parameter names may differ.

-- Inferred from LINQ (NHibernate mapping translation); not concrete SQL
-- Services/SAIF.Services/Claims/Bills/BillService.cs:112
SELECT SUM(CAS.ALLOWED_AMT)
FROM CBP_BILL CB
  CROSS JOIN CBP_AUDITED_SERVICE CAS
  INNER JOIN CBP_AUDIT CA
    ON CA.BILL_ID = CAS.BILL_ID
WHERE CB.BILL_ID = CA.BILL_ID
  AND CB.CLAIM_ID = :claimId
  AND CB.CURRENT_BILL_STATUS_CODE IN (:billtype)
  AND CAS.BILL_PAYMENT_CATEGORY_CODE = :paymentCategory

Translation notes: - Two from clauses produce a cross product filtered by the where; NHibernate emits it theta-style (FROM CBP_BILL cb, CBP_AUDITED_SERVICE cas ...). - asv.Audit.Bill.Id: Audit is a KeyReference on BILL_ID (CbpAuditedServiceMap.cs:19). CbpAudit has an anonymous identifier Id().Column("BILL_ID") (CbpAuditMap.cs:14), so Bill is a non-identifier References (CbpAuditMap.cs:16) -> INNER JOIN CBP_AUDIT, then Bill.Id short-circuits to CA.BILL_ID. The join is logically redundant (both columns are BILL_ID) but follows the mapping; CBP_BILL is not joined a second time. - billtype.Contains(bil.BillStatus.Code) -> IN (:billtype) (list parameter). - reviewedBills.Sum() is invoked twice (L120 and L121) -> the identical aggregate statement executes twice per call. - Same statement as SQL-111 (documented from the CbpBill side).
