# SQL-329: Retrieve TaskCategory

This statement retrieves a single `TASK_CATEGORY_CODE` record for `TaskService`, using either the caller-supplied task category code (`CreateTaskStateless`) or the default claim task category code `CLMM` (`CreateTask`, `ReassignTasks`). The SQL is inferred from the NHibernate LINQ queries and the `TaskCategory` class map shown below — it is not literal SQL text in the source code.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-329 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `TaskCategory` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `CreateTask, CreateTaskStateless, ReassignTasks` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:taskCategoryCode` | Input | string | N/A | Local `taskCategoryCode` (line 497): `taskEdit.TaskCategory` when non-empty, else `ClaimTaskCategoryCode` (`"CLMM"`). |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [TASK_CATEGORY_CODE](../database-tables.md#task_category_code) | SELECT | `Code`, `CODE_DESCR`, `NOTEPAD_REQUIRED_FLAG`, `DEFAULT_ACTION_CODE`, `DEFAULT_PRIORITY_CODE`, `TASK_SOURCE_CODE` |

## LINQ statement

Source: `Services/SAIF.Services/Claims/Tasks/TaskService.cs:498`

```csharp
// Services/SAIF.Services/Claims/Tasks/TaskService.cs:497
var taskCategoryCode = (taskEdit.TaskCategory != string.Empty) ? taskEdit.TaskCategory : ClaimTaskCategoryCode;
var categoryDefaults = _unitOfWork.GetRepository<TaskData.TaskCategory>().Query().SingleOrDefault(x => x.Code == taskCategoryCode);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:589
var defaultCategory = _unitOfWork.GetRepository<TaskData.TaskCategory>().Query().SingleOrDefault(x => x.Code == ClaimTaskCategoryCode);

// Services/SAIF.Services/Claims/Tasks/TaskService.cs:840
var defaultCategory = _unitOfWork.GetRepository<TaskData.TaskCategory>().Query().SingleOrDefault(x => x.Code == ClaimTaskCategoryCode);
```

## 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
-- TaskService.CreateTaskStateless (line 498)
SELECT
  TCC.Code,
  TCC.CODE_DESCR,
  TCC.NOTEPAD_REQUIRED_FLAG,
  TCC.DEFAULT_ACTION_CODE,
  TCC.DEFAULT_PRIORITY_CODE,
  TCC.TASK_SOURCE_CODE
FROM TASK_CATEGORY_CODE TCC
WHERE TCC.Code = :taskCategoryCode
-- NHibernate expects at most one row

-- TaskService.CreateTask (line 589) and ReassignTasks (line 840)
SELECT
  TCC.Code,
  TCC.CODE_DESCR,
  TCC.NOTEPAD_REQUIRED_FLAG,
  TCC.DEFAULT_ACTION_CODE,
  TCC.DEFAULT_PRIORITY_CODE,
  TCC.TASK_SOURCE_CODE
FROM TASK_CATEGORY_CODE TCC
WHERE TCC.Code = 'CLMM'
-- NHibernate expects at most one row
```

Translation notes:

- `SingleOrDefault` -> no row limit; NHibernate expects at most one row.
- `ClaimTaskCategoryCode = "CLMM"` (`TaskService.cs:40`).
