Tables¶

Table	Access	Columns used
Agency	SELECT (hypothetical)	agency_seq_num, agency_name, agency_eff_date, agency_exp_date, policy_holder_paperless_flag, agency_paperless_flag, agency_paperless_request_flag, update_date, update_user, agency_rep_user

LINQ statement¶

Source: Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:30.

// Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:30
var agencies = uow.GetRepository<Agency>();

// Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:56
agencies.Query().First().Id = 0; // this was necessary because the first agency id was automatically changed from 0 to 1 when adding it to list

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
SELECT *
FROM (
  SELECT
    A.agency_seq_num,
    A.agency_name,
    A.agency_eff_date,
    A.agency_exp_date,
    A.policy_holder_paperless_flag,
    A.agency_paperless_flag,
    A.agency_paperless_request_flag,
    A.update_date,
    A.update_user,
    A.agency_rep_user
  FROM Agency A)
WHERE ROWNUM <= 1
-- First(): throws if no row

Translation notes: - Scope split: see SQL-246 — this entry documents the First() read at line 56. - No OrderBy, so "first" is database-order dependent. - .Id = 0 then mutates the identifier of a persistent entity — a real NHibernate session throws HibernateException: identifier of an instance was altered at flush. The source comment confirms this is a test-double workaround.
