# SQL-378: Delete EbillInvoiceBill via ProcessInvoiceFile

This statement deletes each `EbillInvoiceBill` entity associated with an invoice, via `IUnitOfWork.GetRepository<T>().Delete(entity)` inside a `foreach` loop, invoked from `EBillingService.ProcessInvoiceFile` (`Services/SAIF.Services/Claims/EBilling/EBillingService.cs:1169`). One DELETE is issued per row (`EBILL_INVOICE_BILL_SEQ_NUM`). The SQL below is inferred from this repository call and the `EbillInvoiceBill` NHibernate mapping — it is not literal SQL present in source.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-378 |
| **Operation type** | Delete |
| **Execution method** | ORM (IRepository.Delete) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `EbillInvoiceBill` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `ProcessInvoiceFile` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [EBILL_INVOICE_BILL](../database-tables.md#ebill_invoice_bill) | DELETE | `EBILL_INVOICE_BILL_SEQ_NUM` |

## LINQ statement

Source: `Services/SAIF.Services/Claims/EBilling/EBillingService.cs:1169`

```csharp
// Services/SAIF.Services/Claims/EBilling/EBillingService.cs:1167
foreach (var bill in oldInvoiceBills)
{
    _unitOfWork.GetRepository<EbillInvoiceBill>().Delete(bill);
```

## 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 EBILL_INVOICE_BILL
WHERE EBILL_INVOICE_BILL_SEQ_NUM = :Id
```

Translation notes:

- One DELETE per bill returned by `GetInvoiceBills(oldInvoice)` (line 1166).
