# SQL-145: EdiQueryProvider.GetBillBySegmentCount

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-145 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `EdiQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetBillBySegmentCount` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:billReport` | Input | BillReport | N/A | Method argument; bound as its identifier |
| `:segmentCount` | Input | long | N/A | Method argument |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [EDI_BILL](../database-tables.md#edi_bill) | SELECT | `EDI_BILL_SEQ_NUM`, `UPDATE_NUM`, `BILL_ID`, `CLAIM_ID`, `SAIF_CLAIM_NUM`, `POLICY_NUM`, `EDI_BILL_CLM_SEGMENT_ID`, `UPDATE_DATE`, `UPDATE_USER`, `EDI_BILL_REPORT_SEQ_NUM` |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Edi/EdiQueryProvider.cs:33`. The repository is obtained at `Data/SAIF.Data/Queries/Edi/EdiQueryProvider.cs:16`.

```csharp
// Data/SAIF.Data/Queries/Edi/EdiQueryProvider.cs:16
_billRepository = Factory.GetRepository<Bill>().Query();

// Data/SAIF.Data/Queries/Edi/EdiQueryProvider.cs:33
return _billRepository.OrderByDescending(x => x.BillClaimSegmentId).FirstOrDefault(x => x.BillReport  == billReport && x.BillClaimSegmentId < segmentCount);
```

## 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 *
FROM (
  SELECT
    EB.EDI_BILL_SEQ_NUM,
    EB.UPDATE_NUM,
    EB.BILL_ID,
    EB.CLAIM_ID,
    EB.SAIF_CLAIM_NUM,
    EB.POLICY_NUM,
    EB.EDI_BILL_CLM_SEGMENT_ID,
    EB.UPDATE_DATE,
    EB.UPDATE_USER,
    EB.EDI_BILL_REPORT_SEQ_NUM
  FROM EDI_BILL EB
  WHERE EB.EDI_BILL_REPORT_SEQ_NUM = :billReport
    AND EB.EDI_BILL_CLM_SEGMENT_ID < :segmentCount
  ORDER BY EB.EDI_BILL_CLM_SEGMENT_ID DESC
)
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).
- The `OrderByDescending` comes before the predicate-bearing `FirstOrDefault(pred)`. NHibernate folds the predicate into `WHERE` and keeps the ordering.
