# SQL-001: AddressVerificationQueryProvider.GetLocationVerificationRequests

This statement is a read operation invoked through ORM (NHibernate LINQ). Executed by `AddressVerificationQueryProvider.GetLocationVerificationRequests`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-001 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `AddressVerificationQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetLocationVerificationRequests` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `locationsSeqNum` | Input | long | N/A | Method argument of `AddressVerificationQueryProvider.GetLocationVerificationRequests` bound into the ORM expression; NHibernate generates the bind variable at runtime |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [LOCATION_VERIFICATION_REQUEST](../database-tables.md#location_verification_request) | SELECT | LOC_SEQ_NUM, ADDR_VERIFICATION_REQ_SEQ_NUM, REQUEST_DATE, ADDRESS_TABLE_CODE, UPDATE_NUM, CANCEL_DATE, UPDATE_DATE, UPDATE_USER |
| [ADDRESS_VERIFICATION_REQUEST](../database-tables.md#address_verification_request) | JOIN | ADDR_VERIFICATION_REQ_SEQ_NUM, VERIFIED_ADDRESS_SEQ_NUM |

## LINQ statement

Source: `Data/SAIF.Data/Queries/AddressVerification/AddressVerificationQueryProvider.cs:34`. The repository is a class field initialised from `Factory.GetRepository<LocationVerificationRequest>().Query()` at `Data/SAIF.Data/Queries/AddressVerification/AddressVerificationQueryProvider.cs:18`.

```csharp
return locationVerificationRepository.SingleOrDefault(x => x.CancelDate == null
  && x.AddressTable.Code.Trim() == "PROV"
  && x.AddressVerificationRequest.VerifiedAddress != null
  && x.LocId == locationsSeqNum);
```

## 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
SELECT
  LVR.LOC_SEQ_NUM,
  LVR.ADDR_VERIFICATION_REQ_SEQ_NUM,
  LVR.REQUEST_DATE,
  LVR.ADDRESS_TABLE_CODE,
  LVR.UPDATE_NUM,
  LVR.CANCEL_DATE,
  LVR.UPDATE_DATE,
  LVR.UPDATE_USER
FROM LOCATION_VERIFICATION_REQUEST LVR
  INNER JOIN ADDRESS_VERIFICATION_REQUEST AVR
    ON AVR.ADDR_VERIFICATION_REQ_SEQ_NUM = LVR.ADDR_VERIFICATION_REQ_SEQ_NUM
WHERE LVR.CANCEL_DATE IS NULL
  AND TRIM(LVR.ADDRESS_TABLE_CODE) = 'PROV'
  AND AVR.VERIFIED_ADDRESS_SEQ_NUM IS NOT NULL
  AND LVR.LOC_SEQ_NUM = :locationsSeqNum
-- NHibernate expects at most one row
```

Translation notes:
- `x.AddressTable.Code` is the identifier of the `AddressTable` key-reference, so it resolves to the owner column `LVR.ADDRESS_TABLE_CODE` with no join; `ADDRESS_TABLE_CODE` is not accessed as a separate table.
- `x.AddressVerificationRequest.VerifiedAddress != null` resolves to the FK null check `AVR.VERIFIED_ADDRESS_SEQ_NUM IS NOT NULL` with no join; `VERIFIED_ADDRESS` is not accessed as a separate table.
