# SQL-293: Retrieve RegisteredAgent via ListOfRegisteredAgents (property)

This statement retrieves every `RegisteredAgent` row via a full-table NHibernate LINQ query, executed from `Services/SAIF.Services/Legal/Subpoenas/SubpoenaService.cs (L355)` and materialized with `Query().ToList()`. It backs the `ListOfRegisteredAgents` property, which exposes the complete list of registered agents for subpoena processing.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-293 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `SubpoenaService` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `ListOfRegisteredAgents (property)` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| (none) | N/A | N/A | N/A | Full-table read — no filter predicate |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [REGISTERED_AGENT](../database-tables.md#registered_agent) | SELECT | `PROVIDER_SEQ_NUM`, `UPDATE_USER`, `UPDATE_DATE`, `REGISTERED_AGENT_LOC_SEQ_NUM` |

## LINQ statement

Source: `Services/SAIF.Services/Legal/Subpoenas/SubpoenaService.cs:353`

```csharp
// Services/SAIF.Services/Legal/Subpoenas/SubpoenaService.cs:353-355
var listOfRegisteredAgents =
    Mapper.Map<IList<RegisteredAgent>>(
        _unitOfWork.GetRepository<LegalData.RegisteredAgent>().Query().ToList());
```

## 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
  RA.PROVIDER_SEQ_NUM,
  RA.UPDATE_USER,
  RA.UPDATE_DATE,
  RA.REGISTERED_AGENT_LOC_SEQ_NUM
FROM REGISTERED_AGENT RA
```

Translation notes:
- `PROVIDER_SEQ_NUM` is both `Id` and `References` column (`RegisteredAgentMap.cs:12`, `:16`); selected once.
- Full-table read; `.ToList()` materializes.
