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:359
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,
  CD.EXP_DATE,
  CD.UPDATE_USER,
  CD.UPDATE_DATE
FROM CBP_DIAGNOSIS CD
WHERE CD.DIAGNOSIS_CODE = :DiagnosisCode
-- NHibernate expects at most one row

Translation notes: - Executed once per element inside t.ForEach(...) (L357) - N+1 pattern; x.DiagnosisCode is a member of the in-memory contract object -> bind :DiagnosisCode.
