# 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.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-334 |
| **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** | `FillTaskData, 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/Legal/Tasks/LegalTaskService.cs:625`

```csharp
// 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
taskData.TaskPriority = _unitOfWork.GetRepository<TaskData.TaskPriority>().Query()
    .SingleOrDefault(x => x.Code == TaskPriority.Info);

// Services/SAIF.Services/Legal/Tasks/LegalTaskService.cs:969
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 = '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`).
