# SQL-141: EbillServiceQueryProvider.GetEbillService

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-141 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `EbillServiceQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetEbillService` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:ebillId` | Input | long | N/A | Evaluated client-side from the `Ebill` returned by SQL-140 (`ebill.Id`) |
| `:bsvId` | Input | long | N/A | Evaluated client-side from `bsv.Id` (`CbpBillService.Id`, `BILL_SERVICE_SEQ_NUM`) |

## Tables

## 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

  FROM EBILL_SERVICE ES
  WHERE ES.EBILL_SEQ_NUM = :ebillId
    AND ES.EBILL_SERVICE_SUB_NUM = :bsvId
)
WHERE ROWNUM <= 1
```

Translation notes:
- Oracle10 row limit for `FirstOrDefault()`: the query (including any `ORDER BY`) is wrapped in `ROWNUM <= 1` (limit written inline; NHibernate binds it as a parameter at runtime).
- This runs only after the SQL-140 lookup, which supplies `ebill`.
