# SQL-146: Retrieve CollectionCode via GetCollectionCodes

This ORM statement performs a read operation on `CollectionCode` via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Collections/CollectionsService.cs (L1077)`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-146 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `CollectionCode` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetCollectionCodes` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| (none) | N/A | N/A | N/A | No inline filter — full-entity read (`Query().ToList()`/projection) or filters appended later |

## Tables

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

## LINQ statement

Source: `Services/SAIF.Services/Collections/CollectionsService.cs:1077`

```csharp
// Services/SAIF.Services/Collections/CollectionsService.cs:1077-1078
            return Mapper.Map<CollectionCode[]>(UnitOfWork.GetRepository<DataModel.CollectionCode>()
                .Query().OrderBy(x => x.Description).ToList());
```

## 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/Collections/CollectionsService.cs:1077
SELECT
  LCC.Code,
  LCC.CODE_DESCR
FROM LEGAL_COLLECTION_CODE LCC
ORDER BY LCC.CODE_DESCR
```

Translation notes:
- `Id(x => x.Code)` has no `.Column(...)` (CollectionCodeMap.cs) and no FluentNHibernate conventions exist in the repository -> NHibernate default column name `Code`.
