LINQ statement

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/DiagnosisService.cs:58
SELECT *
FROM (
  SELECT
    CD.DIAGNOSIS_CODE,
    CD.UPDATE_NUM,
    CD.ICD_VERSION_CODE,
    CD.DIAGNOSIS_DESCR,
    CD.DIAGNOSIS_SHORT_DESCR,
    CD.DIAGNOSIS_CATEGORY_CODE,
    CD.VALID_MEDICARE_REPORT_FLAG,
    CD.EFF_DATE,

  WHERE CD.DIAGNOSIS_CODE = :code
    AND (:includeExpired = 1 OR (CD.EXP_DATE IS NULL OR CD.EXP_DATE > :today))
)
WHERE ROWNUM <= 1

Translation notes: - includeExpired == true references only a method argument -> pre-evaluated client-side to a constant; rendered as :includeExpired = 1 to show intent. - DateTime.Today -> :today.
