# SQL-096: Retrieve BillService via ListOfBillServiceCodes (property)

This ORM statement performs a read operation on `BillService` via `IUnitOfWork.GetRepository<T>()`, executed from `Services/SAIF.Services/Legal/Bills/BillService.cs (L377)`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-096 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `BillService` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `ListOfBillServiceCodes (property)` |

## 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 |
| --- | --- | --- |
| [BILL_SERVICE_CODE](../database-tables.md#bill_service_code) | SELECT | `CODE`, `CODE_DESCR`, `GL_EXPENSE_ACCOUNT_NUM`, `SPEND_CATEGORY` |

## LINQ statement

Source: `Services/SAIF.Services/Legal/Bills/BillService.cs:376`

```csharp
// Services/SAIF.Services/Legal/Bills/BillService.cs:376-378
                return
                    Mapper.Map<IList<BillServiceCode>>(_unitOfWork.GetRepository<BillData.BillService>().Query())
                        .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/Legal/Bills/BillService.cs:377
SELECT
  BSC.CODE,
  BSC.CODE_DESCR,
  BSC.GL_EXPENSE_ACCOUNT_NUM,
  BSC.SPEND_CATEGORY
FROM BILL_SERVICE_CODE BSC
```

Translation notes:
- `Mapper.Map<IList<BillServiceCode>>(...Query())` enumerates the whole table (no predicate); `.ToList()` is in memory.
