# SQL-178: Retrieve Employee via HasSecurityOverride

This statement looks up the first `Employee` row matching an upper-cased user ID, which `HasSecurityOverride` then checks against a separate claim-security-override provider call. The `Employee` entity's `ClassMap` lives in the external `SAIF.Framework.Data.NHibernate` package; Legends resolved only the table name (`ADP_EMPLOYEE`), so the columns used here are shown as C# property names.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-178 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `Employee` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `HasSecurityOverride` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:userIdUpper` | Input | string | N/A | `= userId.ToUpper()`, client-side → column UserId (unresolved) |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [ADP_EMPLOYEE](../database-tables.md#adp_employee)** | SELECT | full entity; filter UserId (C# property names — column mapping unresolved) |

## LINQ statement

Source: `Services/SAIF.Services/Claims/Information/ClaimInformationService.cs:118`

```csharp
var employee = _uow.GetRepository<Employee>().Query()
  .FirstOrDefault(x => x.UserId == userId.ToUpper());
```

## 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 E.Id, E.UserId, E.EmployeeStatusCode, E.FirstName, E.LastName, E.PreferredName,
           E.EmailAddress, E.Phone, E.Department, E.JobTitle /* , ...remaining EmployeeMap columns */
           -- unresolved mapping: Employee.* (C# property names; physical columns not resolvable)
    FROM   ADP_EMPLOYEE E
    WHERE  E.UserId = :userIdUpper                    -- unresolved mapping: Employee.UserId
) WHERE ROWNUM <= 1;
```

Translation notes:
- ** = unresolved column mapping (C# property names shown). Table name `ADP_EMPLOYEE` is from Legends documentation of `SAIF.Framework.Data.NHibernate`.
- `FirstOrDefault` → Oracle10 dialect wraps the query in `SELECT * FROM (...) WHERE ROWNUM <= 1`.
- `HasClaimSecurityOverride` at L122 is a separate provider query (not this statement).
