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
SELECT
  CSC.CODE,
  CSC.BILL_SERVICE_TYPE_CODE,
  CSC.UPDATE_NUM,
  CSC.EFF_DATE,
  CSC.EXP_DATE,
  CSC.RP_1099_REQ_FLAG,
  CSC.UPDATE_USER,
  CSC.UPDATE_DATE,
  CSC.NURSE_REVIEW_REQUIRED_FLAG,
  CSC.DCBS_REPORT_SERVICE_CODE
FROM CBP_SERVICE_CODE CSC
WHERE CSC.CODE = :code
  AND CSC.BILL_SERVICE_TYPE_CODE = :type
  AND CSC.EFF_DATE <= :serviceDate
  AND COALESCE(CSC.EXP_DATE, :serviceDate) >= :serviceDate
-- SingleOrDefault: NHibernate expects at most one row

Translation notes: - ExpirationDate.GetValueOrDefault(serviceDate) → COALESCE(CSC.EXP_DATE, :serviceDate). NHibernate's LINQ provider supports GetValueOrDefault(x) as coalesce.
