# SQL-074: Retrieve AdpEmployeeFeed via ExtractUsers

This ORM statement performs a read operation on `AdpEmployeeFeed` via `ExtractUsers`, executed from `Services/SAIF.Services/SystemUsers/UserExtractService.cs` (L130-133).

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-074 |
| **Operation type** | Read |
| **Execution method** | ORM (NHibernate LINQ) |
| **Database** | Oracle |
| **Schema** | [unqualified]** |
| **Command type** | N/A (ORM-generated) |
| **Business object** | `AdpEmployeeFeed` |
| **Criteria property** | N/A — ORM |
| **Lifecycle method** | `ExtractUsers` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:EmployeeId` | Input | `string` | N/A | Captured member `userExtract.EmployeeId` |
| `:take` | Input | `int` | N/A | Row limit from `FirstOrDefault()` (value 1) |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [ADP_EMPLOYEE_FEED](../database-tables.md#adp_employee_feed) | SELECT | EMPLOYEE_ID, ADP_EMPLOYEE_FEED_SEQ_NUM, EMAIL_ADDRESS, FIRST_NAME, LAST_NAME, MIDDLE_NAME, USERID_TEXT, EMPLOYEE_STATUS_CODE, PHONE_NUM, PHONE_EXTENSION_NUM, FAX_NUM, PREFERRED_NAME, WORKING_JOB_TITLE_TEXT, MANAGER_EMPLOYEE_ID, DIVISION_NAME |

## LINQ statement

Source: `Services/SAIF.Services/SystemUsers/UserExtractService.cs:130-133`.

```csharp
// Services/SAIF.Services/SystemUsers/UserExtractService.cs:130
var adpEmployee =
    _unitOfWork.GetRepository<AdpEmployeeFeed>()
        .Query()
        .FirstOrDefault(su => su.EmployeeId == userExtract.EmployeeId);
```

## 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
    AEF.EMPLOYEE_ID,
    AEF.ADP_EMPLOYEE_FEED_SEQ_NUM,
    AEF.EMAIL_ADDRESS,
    AEF.FIRST_NAME,
    AEF.LAST_NAME,
    AEF.MIDDLE_NAME,
    AEF.USERID_TEXT,
    AEF.EMPLOYEE_STATUS_CODE,
    AEF.PHONE_NUM,
    AEF.PHONE_EXTENSION_NUM,
    AEF.FAX_NUM,
    AEF.PREFERRED_NAME,
    AEF.WORKING_JOB_TITLE_TEXT,
    AEF.MANAGER_EMPLOYEE_ID,
    AEF.DIVISION_NAME
  FROM ADP_EMPLOYEE_FEED AEF
  WHERE AEF.EMPLOYEE_ID = :EmployeeId)
WHERE ROWNUM <= :take
```

Translation notes:
- The identifier is `Id(x => x.EmployeeId).Column("EMPLOYEE_ID")`; the `Id` property is a plain `Map` to `ADP_EMPLOYEE_FEED_SEQ_NUM`, so both are selected.
- `FirstOrDefault()` on the Oracle10 dialect → `ROWNUM` wrapper; there is no `ORDER BY`, so which row is returned when several match is not deterministic.

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