LINQ statement¶

Source: Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:74.

// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:74
var envRepo = unitOfWork.GetRepository<ErrorGroupEnvironment>();

// Data/SAIF.Data/TestRepository/RepositoryExtensions/OnlineSupportExtensions.cs:79-81
var envs = environments.Query().ToList();

envRepo.Add(new ErrorGroupEnvironment { Id = (counter++), Environment = envs.SingleOrDefault(x => x.EnvironmentName.ToLower() == "webs"), Group = sysGroup });

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
INSERT INTO ERROR_GROUP_ENVIRONMENT (
  ID,
  ERROR_GROUP,
  ENVIRONMENT)
VALUES (
  @Id,
  @Group,
  @Environment)
-- issued 14 times (lines 81-94); SQL Server parameter prefix @

Translation notes: - Not accessed: ERROR_ENVIRONMENT, ERROR_GROUP_CODE — envs.SingleOrDefault(...) and groups.SingleOrDefault(...) run on in-memory List<T> (materialised at lines 58 and 79), not on the repository; the references contribute FK values only. - Id is assigned by the caller (counter++). - The reads that populate envs/groups are SQL-275/SQL-274.
