Sample SQL

Test double — no runtime SQL. This statement executes against TestUnitOfWork/TestRepository<T> (in-memory, List<TEntity>-backed test doubles in SAIF.Framework.Core); no NHibernate session is opened and no SQL is issued at runtime. The SQL below is the hypothetical statement the same expression would produce against a real NHibernate IUnitOfWork using the in-repo mappings, shown to document the mapping shape only — no database table is accessed when this code runs.

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
-- AddCode pattern (SharedExtensions.cs:26-27), issued 12 time(s); first call shown ('SERV', 'SERVICE CENTER')
SELECT *
FROM (
  SELECT 1
  FROM OFFICE_CODE OC
  WHERE OC.CODE = :code
    AND OC.CODE_DESCR = :description)
WHERE ROWNUM <= 1

-- only when the probe returns no row
INSERT INTO OFFICE_CODE (
  CODE,
  CODE_DESCR,
  CANCELLATION_TRACK_CODE,
  LOC_SEQ_NUM,
  PMS_OFFICE_CODE,
  POLICY_REGION_CODE,
  POLICY_RENEWAL_TRACK_CODE)
VALUES (
  :Code,
  :Description,
  :CancellationTrackCode,
  :LocationSeqNum,
  :PMSOfficeCode,
  :PolicyRegionCode,
  :PolicyRenewalTrackCode)

Translation notes: - AddCode(code, description) (Data/SAIF.Data/TestRepository/RepositoryExtensions/SharedExtensions.cs:23-28) runs repo.Query().Any(x => x.Code == code && x.Description == description) and, only if false, repo.Add(new T { Code, Description }). The pair is issued once per call (12 calls, lines 179-193). - Columns not set by AddCode are written as NULL (or the mapped default) in the INSERT.
