# SQL-073: ClaimSecurityOverrideProvider.HasClaimSecurityOverride

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-073 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `ClaimSecurityOverrideProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `HasClaimSecurityOverride` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `claimId` | Input | long | N/A | Method argument of `ClaimSecurityOverrideProvider.HasClaimSecurityOverride` bound into the ORM expression; NHibernate generates the bind variable at runtime |
| `employeeId` | Input | string | N/A | Method argument of `ClaimSecurityOverrideProvider.HasClaimSecurityOverride` bound into the ORM expression; NHibernate generates the bind variable at runtime |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [CL_SECURITY_OVERRIDE](../database-tables.md#cl_security_override) | SELECT (existence check) | CLAIM_ID, EMPLID, EFF_DATE, EXP_DATE |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/ClaimSecurityOverrideProvider.cs:18-23`. The repository is a class field initialised from `Factory.GetRepository<SecurityOverride>()` at `Data/SAIF.Data/Queries/Claims/ClaimSecurityOverrideProvider.cs:13`.

```csharp
var securityOverride = repository
   .Where(x => x.ClaimId == claimId)
   .Where(x => x.EmplId == employeeId)
   .Where(x => x.EffDate <= DateTime.Today)
   .Where(x => x.ExpDate >= DateTime.Today);
return securityOverride.Any();
```

## 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 1
FROM CL_SECURITY_OVERRIDE CSO
WHERE CSO.CLAIM_ID = :claimId
  AND CSO.EMPLID = :employeeId
  AND CSO.EFF_DATE <= :today
  AND CSO.EXP_DATE >= :today
  AND ROWNUM <= 1
```

Translation notes:
- The chained `Where` calls combine with `AND`.
- `DateTime.Today` is evaluated client-side (application server local date, midnight) and bound as a parameter; it is not translated to `SYSDATE`/`TRUNC(SYSDATE)`.
- `Any()` returns a boolean; no entity columns are hydrated.
- Rows with NULL `EXP_DATE` do not match, so an open-ended override is not treated as active.
