SQL-370: Delete DocumentDistributionLog via DeleteRequestDistributions

This statement deletes each DocumentDistributionLog entity returned by a query for distribution logs of a given document request (DOCUMENT_REQUEST_LOG_SEQ_NUM = :requestId), via IUnitOfWork.GetRepository<T>().Delete(entity) inside a foreach loop, invoked from TemplateSearchService.DeleteRequestDistributions (Services/SAIF.Services/Documents/TemplateSearchService.cs:865). One DELETE is issued per row. The SQL below is inferred from this repository call and the DocumentDistributionLog NHibernate mapping — it is not literal SQL present in source.

LINQ statement

Source: Services/SAIF.Services/Documents/TemplateSearchService.cs:865

// Services/SAIF.Services/Documents/TemplateSearchService.cs:858
IEnumerable<DocumentDistributionLog> logs = unitOfWork.GetRepository<DocumentDistributionLog>().Query()
                                          .Where(a => a.DocumentRequestLogSeqNum == requestId);

// Services/SAIF.Services/Documents/TemplateSearchService.cs:863
foreach (var log in logs)
{
    unitOfWork.GetRepository<DocumentDistributionLog>().Delete(log);

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
DELETE FROM DOCUMENT_DISTRIBUTION_LOG
WHERE DOCUMENT_DIST_LOG_SEQ_NUM = :Id

Translation notes:

  • One DELETE per row of the logs query (lines 858-859, WHERE DOCUMENT_REQUEST_LOG_SEQ_NUM = :requestId), which is enumerated by the foreach at line 863 - that read is a separate statement.
