# SQL-141: Retrieve ClaimNoteCategory via CreateTaskNote

This ORM statement performs a read operation on `ClaimNoteCategory` via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Claims/Tasks/TaskService.cs (L819)`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-141 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `ClaimNoteCategory` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `CreateTaskNote` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `_notePreferences["CategoryCode"]` | Input | ** | N/A | `x.Code == _notePreferences["CategoryCode"]` → column CODE |
| `_notePreferences["TypeCode"]` | Input | ** | N/A | `x.Code == _notePreferences["TypeCode"]` → column CODE |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [CLAIM_ACTIVITY_CATEGORY_CODE](../database-tables.md#claim_activity_category_code) | SELECT | `CODE`, `CODE_DESCR`, `EXTERNAL_VIEW_DEFAULT_FLAG` |

## LINQ statement

Source: `Services/SAIF.Services/Claims/Tasks/TaskService.cs:819`

```csharp
// Services/SAIF.Services/Claims/Tasks/TaskService.cs:819-821
                ClaimNoteCategory = _unitOfWork.GetRepository<ClaimNoteCategory>()
                    .Query()
                    .SingleOrDefault(x => x.Code == _notePreferences["CategoryCode"]),
```

## 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
-- Services/SAIF.Services/Claims/Tasks/TaskService.cs:819
SELECT
  CACC.CODE,
  CACC.CODE_DESCR,
  CACC.EXTERNAL_VIEW_DEFAULT_FLAG
FROM CLAIM_ACTIVITY_CATEGORY_CODE CACC
WHERE CACC.CODE = :CategoryCode
-- NHibernate expects at most one row
```

Translation notes:
- `_notePreferences["CategoryCode"]` is a dictionary lookup on a field, evaluated client-side -> bind `:CategoryCode`.
