LINQ statement¶

Source: Services/SAIF.Services/BatchProcessing/BatchProcessingService.cs:18

// Services/SAIF.Services/BatchProcessing/BatchProcessingService.cs:18
            _repository = _unitOfWork.GetRepository<BatchProcessLog>();

// Services/SAIF.Services/BatchProcessing/BatchProcessingService.cs:51-52
            return _repository.Query()
                .SingleOrDefault(x => x.Module == moduleName);

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
-- Services/SAIF.Services/BatchProcessing/BatchProcessingService.cs:51
SELECT
  BPL.module,
  BPL.control_text,
  BPL.run_date
FROM batch_process_log BPL
WHERE BPL.module = :moduleName
-- NHibernate expects at most one row

Translation notes: - Repository obtained from field _repository = _unitOfWork.GetRepository<BatchProcessLog>() (L18).
