SQL-342: Retrieve TradingAs via GetTradingAsById¶

This ORM statement performs a read operation on TradingAs, retrieving exactly one row where Id matches, via IUnitOfWork.GetRepository<T>(), executed from Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs (L32). The SQL below is inferred from the LINQ expression and the TradingAs NHibernate mapping (TRADING_AS); it is not literal SQL text present in source.

TRADING_AS	SELECT	`TRADING_SEQ_NUM`, `TRADING_AS_NAME`, `TRADING_AS_NAME_EFF_DATE`, `TRADING_AS_CANCEL_DATE`, `POLICY_NUM`

LINQ statement¶

Source: Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs:32

// Services/SAIF.Services/Policies/Certificates/Information/CertificateInformationDataHelper.cs:32
return unitOfWork.GetRepository<TradingAs>()
    .Query().Single(ta => ta.Id == tradingAsId);

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
  TA.TRADING_SEQ_NUM,
  TA.TRADING_AS_NAME,
  TA.TRADING_AS_NAME_EFF_DATE,
  TA.TRADING_AS_CANCEL_DATE,
  TA.POLICY_NUM
FROM TRADING_AS TA
WHERE TA.TRADING_SEQ_NUM = :tradingAsId
-- NHibernate expects at most one row

Translation notes:

Single -> no row limit; NHibernate expects exactly one row.
References(Policy).Column("POLICY_NUM") contributes the FK column only; no join.
