# SQL-154: LegalQueryProvider.GetClaimIdForCase

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-154 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `LegalQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetClaimIdForCase` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [LEGAL_CASE](../database-tables.md#legal_case) | SELECT | `LEGAL_CASE_SEQ_NUM`, `CLAIM_ID`, `WCB_NUM`, `DCBS_NUM`, `OALJ_NUM`, `OWCP_NUM`, `BRB_NUM`, `REQUEST_DATE`, `CLAIM_IMAGE_ALERTS_FLAG`, `CREATE_USER`, `CREATE_DATE`, `UPDATE_USER`, `UPDATE_DATE`, `MOST_RECENT_HEARING_SEQ_NUM`, `CASE_STATUS_CODE`, `WORKER_ATTY_PROV_LOC_ID`, `WORKER_ATTY_FIRM_PROV_LOC_ID` |

## 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
    LC.LEGAL_CASE_SEQ_NUM,
    LC.CLAIM_ID,
    LC.WCB_NUM,
    LC.DCBS_NUM,
    LC.OALJ_NUM,
    LC.OWCP_NUM,
    LC.BRB_NUM,
    LC.REQUEST_DATE,
    LC.CLAIM_IMAGE_ALERTS_FLAG,
    LC.CREATE_USER,
    LC.CREATE_DATE,
    LC.UPDATE_USER,
    LC.UPDATE_DATE,
    LC.MOST_RECENT_HEARING_SEQ_NUM,
    LC.CASE_STATUS_CODE,
    LC.WORKER_ATTY_PROV_LOC_ID,
    LC.WORKER_ATTY_FIRM_PROV_LOC_ID
  FROM LEGAL_CASE LC
  WHERE LC.WCB_NUM = :claimNumOrCaseNumber
    OR LC.BRB_NUM = :claimNumOrCaseNumber
    OR LC.DCBS_NUM = :claimNumOrCaseNumber
    OR LC.OALJ_NUM = :claimNumOrCaseNumber
    OR LC.OWCP_NUM = :claimNumOrCaseNumber
)
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).
