LINQ statement¶

Source: Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:32

return Factory.GetRepository<ImageSystem>().Query()
    .SingleOrDefault(ic => ic.TowId == towId);

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
  <all mapped columns of ImageSystem> -- unresolved mapping: ImageSystem column list not documented
FROM IMGSYS IS1
WHERE IS1.<TowId column> = :towId -- unresolved mapping: ImageSystem.TowId
-- NHibernate expects at most one row

Translation notes: - The alias IS1 is used because IS is an Oracle reserved word.
