# SQL-146: EmployeeQueryProvider.GetWcisEmployee

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

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-146 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle* |
| **Schema** | Unknown** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `EmployeeQueryProvider` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `GetWcisEmployee` |

## Parameters

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

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| `WCIS_Employee**` | SELECT | unresolved (see Unresolved mapping) |

## LINQ statement

Source: `Data/SAIF.Data/Queries/Employees/EmployeeQueryProvider.cs:13`

```csharp
// Data/SAIF.Data/Queries/Employees/EmployeeQueryProvider.cs:13
return Factory.GetRepository<WcisEmployee>().Query()
                    .FirstOrDefault(x => x.Id == 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
    <all mapped columns of WcisEmployee> -- unresolved mapping: WcisEmployee column list not documented
  FROM WCIS_Employee WE
  WHERE WE.<Id column> = :id -- unresolved mapping: WcisEmployee.Id
)
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).
- The `**` table marker means the mapping lives outside this repository; the table name is confirmed but the columns are not.
- Placeholders in `<angle brackets>` mark mapping gaps. They are not SQL; they are the skill's unresolved-mapping markers.

> **Note:** Statements marked with `**` could not be confirmed; treat
> as unknown until verified.
