LINQ statement¶

Source: Data/SAIF.Data/Queries/Policies/PolicyQueryProvider.cs:44-45.

public Business GetBusiness(long policyNumber)
{
    return Factory.GetRepository<Business>().Query()
        .SingleOrDefault((x => x.PolicyNumber == policyNumber && x.IsPrimaryBusiness));
}

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
  B.POLICY_NUM,
  B.BUS_SEQ_NUM,
  B.BUS_EFF_DATE,
  B.BUS_EXP_DATE,
  B.FEID_NUM,
  B.PRIMARY_BUS_FLAG
FROM BUSINESS B
WHERE B.POLICY_NUM = :policyNumber
  AND B.PRIMARY_BUS_FLAG = 'Y'
-- SingleOrDefault: NHibernate expects at most one row

Translation notes: - IsPrimaryBusiness → PRIMARY_BUS_FLAG, CustomType<YesNoType>() (BusinessMap.cs:20) → 'Y'.
