# SQL-213: Retrieve InterestRateValue via GetInterestRates

This statement retrieves every interest rate value, ordered by rate, so that `CollectionsService.GetInterestRates` can populate a rate list. It is issued through NHibernate LINQ against the `InterestRateValue` entity from `Services/SAIF.Services/Collections/CollectionsService.cs:1097`.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-213 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `CollectionsService` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetInterestRates` |

## Parameters

**Parameters:** None.

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [INTEREST_RATE_VALUE](../database-tables.md#interest_rate_value) | SELECT | INTEREST_RATE_VALUE |

## LINQ statement

Source: `Services/SAIF.Services/Collections/CollectionsService.cs:1097`

```csharp
return Mapper.Map<InterestRateValue[]>(UnitOfWork.GetRepository<DataModel.InterestRateValue>()
    .Query().OrderBy(x => x.Rate).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 IRV.INTEREST_RATE_VALUE
FROM   INTEREST_RATE_VALUE IRV
ORDER BY IRV.INTEREST_RATE_VALUE;
```

Translation notes:
- The single mapped column is the identifier `Rate` → `INTEREST_RATE_VALUE`.
