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
    ERS.EBILL_RESPONSE_SET_SEQ_NUM,
    ERS.UPDATE_NUM,
    ERS.EBILL_RESPONSE_SET_DESCR,
    ERS.STATUS_CATEGORY_CODE,
    ERS.RESPONSE_STATUS_CODE,
    ERS.ACTION_CODE,
    ERS.UPDATE_USER,
    ERS.UPDATE_DATE,
    ERS.EBILL_STATUS_CODE
  FROM EBILL_RESPONSE_SET ERS
  WHERE ERS.EBILL_RESPONSE_SET_SEQ_NUM = :responseSetSequenceNumber
)
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).
