# SQL-362: Delete BatchProviderAddress via StatelessProcessProviderAddressesForUpdates

This ORM statement re-loads a `PROVIDER_ADDRESS` row by identifier and then deletes it, as part of the manual-rollback path in batch provider-address updates, executed from `Services/SAIF.Services/AddressVerificationService/AddressVerificationService.cs (L121)`. The SQL below is inferred from the `IRepository<BatchProviderAddress>.Get`/`.Delete` calls and the `BatchProviderAddress` NHibernate mapping, not literal SQL text in source.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-362 |
| **Operation type** | Delete |
| **Execution method** | ORM (IRepository.Delete) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `BatchProviderAddress` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `StatelessProcessProviderAddressesForUpdates` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:Id` | Input | long | N/A | Identifier of the BatchProviderAddress being deleted (`PROVIDER_ADDRESS_SEQ_NUM`) |
| `:oldVersion` | Input | int | N/A | Current `UPDATE_NUM` value (optimistic-concurrency check) |
| `:newAddressId` | Input | long | N/A | Local `newAddressId` - value returned by `GetLastInsertId(...)` (line 108) |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [PROVIDER_ADDRESS](../database-tables.md#provider_address) | SELECT | `PROVIDER_ADDRESS_SEQ_NUM`, `UPDATE_NUM`, `CITY_NAME`, `COUNTRY_CODE`, `EFF_DATE`, `EXP_DATE`, `ADDRESS_LINE1`, `ADDRESS_LINE2`, `ADDRESS_LINE3`, `ADDRESS_LINE4`, `ZIP_CODE_EXT`, `STATE_CODE`, `ZIP_CODE`, `UPDATE_DATE`, `UPDATE_USER`, `FOREIGN_ADDRESS_FLAG`, `PROVIDER_ADDRESS_CODE`, `PROVIDER_LOCATION_SEQ_NUM` |
| [PROVIDER_ADDRESS](../database-tables.md#provider_address) | DELETE | `PROVIDER_ADDRESS_SEQ_NUM`, `UPDATE_NUM` |

## LINQ statement

Source: `Services/SAIF.Services/AddressVerificationService/AddressVerificationService.cs:121`

```csharp
// Services/SAIF.Services/AddressVerificationService/AddressVerificationService.cs:121
_unitOfWork.GetRepository<BatchProviderAddress>().Delete(
    _unitOfWork.GetRepository<BatchProviderAddress>().Get(newAddressId));
```

## 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
-- Get(newAddressId)
SELECT
  PA.PROVIDER_ADDRESS_SEQ_NUM,
  PA.UPDATE_NUM,
  PA.CITY_NAME,
  PA.COUNTRY_CODE,
  PA.EFF_DATE,
  PA.EXP_DATE,
  PA.ADDRESS_LINE1,
  PA.ADDRESS_LINE2,
  PA.ADDRESS_LINE3,
  PA.ADDRESS_LINE4,
  PA.ZIP_CODE_EXT,
  PA.STATE_CODE,
  PA.ZIP_CODE,
  PA.UPDATE_DATE,
  PA.UPDATE_USER,
  PA.FOREIGN_ADDRESS_FLAG,
  PA.PROVIDER_ADDRESS_CODE,
  PA.PROVIDER_LOCATION_SEQ_NUM
FROM PROVIDER_ADDRESS PA
WHERE PA.PROVIDER_ADDRESS_SEQ_NUM = :newAddressId

-- Delete
DELETE FROM PROVIDER_ADDRESS
WHERE PROVIDER_ADDRESS_SEQ_NUM = :Id
  AND UPDATE_NUM = :oldVersion
```

Translation notes:

- `Version(x => x.UpdateNumber).Column("UPDATE_NUM")` adds the old-version predicate to the DELETE.
- `IsForeign` (`FOREIGN_ADDRESS_FLAG`) is `YesNoType` (`'Y'`/`'N'`).
- `Get(newAddressId)` is evaluated inline as the argument to `Delete`, so the identifier SELECT is part of this call expression and is shown first.
- If `Get` returns `null` (no row), `Delete(null)` throws; the enclosing `catch` (line 125) rethrows as "Failed to manually rollback legacy updates."
