# SQL-060: ClaimQueryProvider.GetClaimsMissingTaxId

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-060 |
| **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** | `GetClaimsMissingTaxId` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [CL_INJURY_CLAIM](../database-tables.md#cl_injury_claim) | SELECT | all 100 mapped `InjuryClaim` columns listed in the Sample SQL below; filter on RECEIVED_DATE; join on WORKER_ID |
| [CL_CLAIM_PERSON](../database-tables.md#cl_claim_person) | JOIN (implicit, via `Worker`) | PERSON_ID, PRIMARY_TAX_ID |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/ClaimQueryProvider.cs:229-232`. The repository is a class field, `claimRepo`, initialised from `Factory.GetRepository<InjuryClaim>().Query()` at `Data/SAIF.Data/Queries/Claims/ClaimQueryProvider.cs:39`.

```csharp
var claimsMissingSSN = claimRepo.Where(injuryClaim =>
    injuryClaim.ReceivedDate > lookbackDate
    && (injuryClaim.Worker.PrimaryTaxId == " ")
    ).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.

Translation notes:
- `injuryClaim.Worker.PrimaryTaxId` is a non-identifier property of the `Worker` key-reference, so this navigation is **not** short-circuited: it produces a real `INNER JOIN CL_CLAIM_PERSON CCP ON CCP.PERSON_ID = CIC.WORKER_ID`.
- A single space `' '` is the literal compared. Rows whose `PRIMARY_TAX_ID` is `NULL` are not returned.
- Only the `CL_CLAIM_PERSON` columns used in the predicate are read. The `Worker` entity itself is not eagerly fetched; it is lazy-loaded if touched later.
