# SQL-139: Retrieve ClaimNoteCategory

This ORM statement performs a read operation on `ClaimNoteCategory` via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs (L191, L244, L285, L382)`.

| **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** | `CreateNote, GetCategories, GetCategoryDesc, SaveNote` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `noteEdit.Category.Code` | Input | ** | N/A | `x.Code == noteEdit.Category.Code` → column CODE |
| `noteEdit.Type.Code` | Input | ** | N/A | `x.Code == noteEdit.Type.Code` → column CODE |
| `categoryCode` | Input | ** | N/A | `x.Code == categoryCode` → 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/Notes/ClaimNotesService.cs:191`

```csharp
// Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:191
                noteData.ClaimNoteCategory = UnitOfWork.GetRepository<ClaimNoteCategory>().Query().SingleOrDefault(x => x.Code == noteEdit.Category.Code);

// Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:244-246
            var query = UnitOfWork.GetRepository<ClaimNoteCategory>().Query().OrderBy(x => x.Description);

            return Mapper.Map<NoteCategory[]>(query.ToList());

// Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:284-287
                    ClaimNoteCategory =
                        UnitOfWork.GetRepository<ClaimNoteCategory>()
                            .Query()
                            .SingleOrDefault(x => x.Code == noteEdit.Category.Code),

// Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:382-384
            var catcode = UnitOfWork.GetRepository<ClaimNoteCategory>()
                .Query()
                .SingleOrDefault(x => x.Code == 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/Notes/ClaimNotesService.cs:191
SELECT
  CACC.CODE,
  CACC.CODE_DESCR,
  CACC.EXTERNAL_VIEW_DEFAULT_FLAG
FROM CLAIM_ACTIVITY_CATEGORY_CODE CACC
WHERE CACC.CODE = :Code
-- NHibernate expects at most one row

-- Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:244
SELECT
  CACC.CODE,
  CACC.CODE_DESCR,
  CACC.EXTERNAL_VIEW_DEFAULT_FLAG
FROM CLAIM_ACTIVITY_CATEGORY_CODE CACC
ORDER BY CACC.CODE_DESCR

-- Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:285
SELECT
  CACC.CODE,
  CACC.CODE_DESCR,
  CACC.EXTERNAL_VIEW_DEFAULT_FLAG
FROM CLAIM_ACTIVITY_CATEGORY_CODE CACC
WHERE CACC.CODE = :Code
-- NHibernate expects at most one row

-- Services/SAIF.Services/Claims/Notes/ClaimNotesService.cs:382
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:
- `noteEdit.Category.Code` -> bind `:Code`.
- `HasManyToMany(ClaimNoteTypes)` (ClaimNoteCategoryMap.cs) is lazy and not selected.
