# SQL-373: Delete DocumentRequestLog via DeleteTemplateRequests

This statement deletes each `DocumentRequestLog` entity in a result set for a given template, via `IUnitOfWork.GetRepository<T>().Delete(entity)` inside a `foreach` loop, invoked from `TemplateSearchService.DeleteTemplateRequests` (`Services/SAIF.Services/Documents/TemplateSearchService.cs:886`). One DELETE is issued per row (`DOCUMENT_REQUEST_LOG_SEQ_NUM`). The SQL below is inferred from this repository call and the `DocumentRequestLog` NHibernate mapping — it is not literal SQL present in source.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-373 |
| **Operation type** | Delete |
| **Execution method** | ORM (IRepository.Delete) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `DocumentRequestLog` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `DeleteTemplateRequests` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [DOCUMENT_REQUEST_LOG](../database-tables.md#document_request_log) | DELETE | `DOCUMENT_REQUEST_LOG_SEQ_NUM` |

## LINQ statement

Source: `Services/SAIF.Services/Documents/TemplateSearchService.cs:886`

```csharp
// Services/SAIF.Services/Documents/TemplateSearchService.cs:884
foreach (var result in results)
{
    unitOfWork.GetRepository<DocumentRequestLog>().Delete(result);
```

## 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 DOCUMENT_REQUEST_LOG
WHERE DOCUMENT_REQUEST_LOG_SEQ_NUM = :Id
```

Translation notes:

- `UPDATE_NUM` is mapped with `Map` (line 27, with a "add version command" TODO at line 26), so there is no version predicate.
- One DELETE per row of `results` (lines 873-874, `WHERE DOCUMENT_TEMPLATE_SEQ_NUM = :templateId` - `a.MyDocTemplate.Id` short-circuits to the FK column) - that read is separate and is enumerated twice (lines 878 and 884).
