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 *
FROM (
  SELECT
    EP.EBILL_PATIENT_SEQ_NUM,
    EP.UPDATE_NUM,
    EP.SUBSCRIBER_NAME,
    EP.SUBSCRIBER_LEVEL_NUMBER,
    EP.PATIENT_LEVEL_NUMBER,
    EP.CLAIM_NUM,
    EP.BIRTH_DATE,
    EP.GENDER_CODE,
    EP.PATIENT_LAST_NAME,
    EP.PATIENT_FIRST_NAME,
    EP.PATIENT_MIDDLE_NAME,

    EP.PATIENT_ADDRESS_SEQ_NUM
  FROM EBILL_PATIENT EP
  WHERE EP.EBILL_PATIENT_SEQ_NUM = :patientId
)
WHERE ROWNUM <= 1

Translation notes:

Oracle10 row limit for FirstOrDefault(): the query (including any ORDER BY) is wrapped in ROWNUM <= 1 (limit written inline; NHibernate binds it as a parameter at runtime).
