# SQL-370: Delete DocumentDistributionLog via DeleteRequestDistributions

This statement deletes each `DocumentDistributionLog` entity returned by a query for distribution logs of a given document request (`DOCUMENT_REQUEST_LOG_SEQ_NUM = :requestId`), via `IUnitOfWork.GetRepository<T>().Delete(entity)` inside a `foreach` loop, invoked from `TemplateSearchService.DeleteRequestDistributions` (`Services/SAIF.Services/Documents/TemplateSearchService.cs:865`). One DELETE is issued per row. The SQL below is inferred from this repository call and the `DocumentDistributionLog` NHibernate mapping — it is not literal SQL present in source.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-370 |
| **Operation type** | Delete |
| **Execution method** | ORM (IRepository.Delete) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `DocumentDistributionLog` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `DeleteRequestDistributions` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [DOCUMENT_DISTRIBUTION_LOG](../database-tables.md#document_distribution_log) | DELETE | `DOCUMENT_DIST_LOG_SEQ_NUM` |

## LINQ statement

Source: `Services/SAIF.Services/Documents/TemplateSearchService.cs:865`

```csharp
// Services/SAIF.Services/Documents/TemplateSearchService.cs:858
IEnumerable<DocumentDistributionLog> logs = unitOfWork.GetRepository<DocumentDistributionLog>().Query()
                                          .Where(a => a.DocumentRequestLogSeqNum == requestId);

// Services/SAIF.Services/Documents/TemplateSearchService.cs:863
foreach (var log in logs)
{
    unitOfWork.GetRepository<DocumentDistributionLog>().Delete(log);
```

## 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_DISTRIBUTION_LOG
WHERE DOCUMENT_DIST_LOG_SEQ_NUM = :Id
```

Translation notes:

- One DELETE per row of the `logs` query (lines 858-859, `WHERE DOCUMENT_REQUEST_LOG_SEQ_NUM = :requestId`), which is enumerated by the `foreach` at line 863 - that read is a separate statement.
