# SQL-363: Delete BillOverride via Delete

This ORM statement deletes an `EDI_BILL_OVERRIDE` row identified by its bill identifier, executed from `Services/SAIF.Services/Edi/BillOverrideService.cs (L160)`. The SQL below is inferred from the `IRepository<BillOverride>.Delete` call and the `BillOverride` NHibernate mapping, not literal SQL text in source.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-363 |
| **Operation type** | Delete |
| **Execution method** | ORM (IRepository.Delete) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `BillOverride` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `Delete` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:Id` | Input | long? | N/A | Identifier of the BillOverride being deleted (`BILL_ID`) |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [EDI_BILL_OVERRIDE](../database-tables.md#edi_bill_override) | DELETE | `BILL_ID` |

## LINQ statement

Source: `Services/SAIF.Services/Edi/BillOverrideService.cs:160`. The entity is loaded on the preceding line, `Services/SAIF.Services/Edi/BillOverrideService.cs:159`.

```csharp
// Services/SAIF.Services/Edi/BillOverrideService.cs:159
var billOverride = GetOverrideById(id);
unitOfWork.GetRepository<DataModel.BillOverride>().Delete(billOverride);
```

## 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
DELETE FROM EDI_BILL_OVERRIDE
WHERE BILL_ID = :Id
```

Translation notes:

- Entity loaded by `GetOverrideById(id)` (line 159) - a separate read.
