## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `legalBillService.BillService.Code` | Input | ** | N/A | `x.Code == legalBillService.BillService.Code` → column CODE |

## Tables

| [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/BillSaveService.cs:438`

```csharp
// Services/SAIF.Services/Legal/Bills/BillSaveService.cs:438-440
                billService.BillService = _unitOfWork.GetRepository<BillData.BillService>()
                    .Query()
                    .SingleOrDefault(x => x.Code == legalBillService.BillService.Code);
```

## 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/BillSaveService.cs:438
SELECT
  BSC.CODE,
  BSC.CODE_DESCR,
  BSC.GL_EXPENSE_ACCOUNT_NUM,
  BSC.SPEND_CATEGORY
FROM BILL_SERVICE_CODE BSC
WHERE BSC.CODE = :Code
-- NHibernate expects at most one row
```

Translation notes:
- `legalBillService.BillService.Code` is a captured in-memory object member -> bind `:Code`.
