SQL-334: Retrieve TaskPriority

This ORM statement performs a read operation on TaskPriority, retrieving the single row matching a literal Code value (URG or INFO), via IUnitOfWork.GetRepository<T>(), executed from Services/SAIF.Services/Legal/Tasks/LegalTaskService.cs (L625, L640, L969). The SQL below is inferred from the LINQ expressions and the TaskPriority NHibernate mapping (TASK_PRIORITY_CODE); it is not literal SQL text present in source.

Source: Services/SAIF.Services/Legal/Tasks/LegalTaskService.cs:625

// Services/SAIF.Services/Legal/Tasks/LegalTaskService.cs:625
var urgentTaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query().SingleOrDefault(x => x.Code == TaskPriority.Urgent);

// Services/SAIF.Services/Legal/Tasks/LegalTaskService.cs:640

    .SingleOrDefault(x => x.Code == TaskPriority.Info);

var urgentTaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query().SingleOrDefault(x => x.Code == TaskPriority.Urgent);

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
  TPC.Code,
  TPC.CODE_DESCR
FROM TASK_PRIORITY_CODE TPC
WHERE TPC.Code = 'URG' -- lines 625 and 969 (TaskPriority.Urgent); line 640 uses 'INFO' (TaskPriority.Info)
-- NHibernate expects at most one row

Translation notes:

  • SingleOrDefault -> no row limit; NHibernate expects at most one row.
  • TaskPriority here is SAIF.Core.Contracts.Tasks.TaskPriority (the data type is aliased TaskData): Urgent = "URG", Info = "INFO" (Core/SAIF.Core/Contracts/Tasks/TaskPriority.cs:7,11).
