# SQL-056: ClaimQueryProvider.GetClaimFromInjuryClaimCrossReference

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

## Classification

| Field | Value |

| **SQL ID** | SQL-056 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `ClaimQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetClaimFromInjuryClaimCrossReference` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `customerClaimNumber` | Input | string | N/A | Method argument of `ClaimQueryProvider.GetClaimFromInjuryClaimCrossReference` bound into the ORM expression; NHibernate generates the bind variable at runtime |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [LPT_CLAIM_CROSS_REFERENCE](../database-tables.md#lpt_claim_cross_reference) | SELECT | CUSTOMER_CLAIM_NUMBER, POLICY_NUMBER, CLAIM_ID, HISTORICAL_FLAG |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/ClaimQueryProvider.cs:100`.

```csharp
var xRef = Factory.GetRepository<InjuryClaimCrossReference>().Query().SingleOrDefault(x => x.CustomerClaimNumber == customerClaimNumber);
```

## 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
  LCCR.CUSTOMER_CLAIM_NUMBER,
  LCCR.POLICY_NUMBER,
  LCCR.CLAIM_ID,
  LCCR.HISTORICAL_FLAG
FROM LPT_CLAIM_CROSS_REFERENCE LCCR
WHERE LCCR.CUSTOMER_CLAIM_NUMBER = :customerClaimNumber
-- NHibernate expects at most one row
```

Translation notes:
- The filter is on the identifier column, so at most one row can match.
- `IsValidClaim(xRef.ClaimId)` and the claim load that follows run as separate statements outside this page.
