# SQL-335: Retrieve TaskPriority

This ORM statement performs a read operation on `TaskPriority`, retrieving the single row matching a literal `Code` value (`INFO` or `URG`), via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Claims/Tasks/TaskService.cs (L384, L499, L518, L590, L604, L841)`. 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.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-335 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `TaskPriority` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `CreateTask, CreateTaskStateless, GetAdditionalInfoTask, ReassignTasks` |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [TASK_PRIORITY_CODE](../database-tables.md#task_priority_code) | SELECT | `Code`, `CODE_DESCR` |

## LINQ statement

Source: `Services/SAIF.Services/Claims/Tasks/TaskService.cs:384`

```csharp
// Services/SAIF.Services/Claims/Tasks/TaskService.cs:384
task.TaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query()
    .SingleOrDefault(x => x.Code == TaskPriority.Info);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:499
var urgentTaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query().SingleOrDefault(x => x.Code == TaskPriority.Urgent);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:518
newTask.TaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query()
    .SingleOrDefault(x => x.Code == TaskPriority.Info);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:590
var urgentTaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query().SingleOrDefault(x => x.Code == TaskPriority.Urgent);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:604
taskData.TaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query()
    .SingleOrDefault(x => x.Code == TaskPriority.Info);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:841
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.

```sql
-- Inferred from LINQ (NHibernate mapping translation); not concrete SQL
SELECT
  TPC.Code,
  TPC.CODE_DESCR
FROM TASK_PRIORITY_CODE TPC
WHERE TPC.Code = 'INFO' -- lines 384, 518, 604 (TaskPriority.Info); lines 499, 590, 841 use 'URG' (TaskPriority.Urgent)
-- NHibernate expects at most one row
```

Translation notes:

- `SingleOrDefault` -> no row limit; NHibernate expects at most one row.
- `TaskPriority.Info = "INFO"`, `TaskPriority.Urgent = "URG"` (`Core/SAIF.Core/Contracts/Tasks/TaskPriority.cs:7,11`).
