LINQ statement¶

Source: Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:68.

// Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:68
var volMarketType = uow.GetRepository<MarketTypeCode>().Query().SingleOrDefault(x => x.Code == "VOL");

// Data/SAIF.Data/TestRepository/RepositoryExtensions/PolicyExtensions.cs:69
var arpMarketType = uow.GetRepository<MarketTypeCode>().Query().SingleOrDefault(x => x.Code == "ARP");

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
-- line 68: Code == "VOL"
SELECT
  MTC.CODE,
  MTC.DESCR
FROM MARKET_TYPE_CODE MTC
WHERE MTC.CODE = :p0  -- 'VOL'
-- SingleOrDefault

-- line 69: Code == "ARP"
SELECT
  MTC.CODE,
  MTC.DESCR
FROM MARKET_TYPE_CODE MTC
WHERE MTC.CODE = :p0  -- 'ARP'
-- SingleOrDefault

Translation notes: - String constants (and captured values) are bound as parameters by NHibernate (:p0); the literal is shown in the trailing comment.
