## What it does
**SQL Query Description**
==========================

### Overview

This SQL query retrieves data from two tables: `MercoPart` and `AddnlPROC`. It joins the two tables based on a common column, `PartNumber`, and calculates additional statistics.

### Table Overview

*   **MercoPart**: This table contains information about parts managed by Merco.
    *   Columns:
        *   `PN`: Part Number (primary key)
        *   `LastMonthQty`: Quantity of the part in stock for the last month
*   **AddnlPROC**: This table contains additional process data related to parts.
    *   Columns:
        *   `PartNumber` (foreign key referencing `MercoPart.PN`)
        *   `WC2`, `WC3`, `WC4`: Additional processing values
        *   `Machine`: Machine used for the part's production
        *   `RunStd`: Standard run time for the part

### Query Details

The query performs a left join on the two tables based on the `PartNumber` column. The results include the following calculations:

*   **MthExtHrs**: Extented hours worked in the last month, calculated as `LastMonthQty * RunStd`
*   **DayExtHrs**: Extented hours worked per day, calculated as `(LastMonthQty * RunStd) / 22`

### SELECT Statement

The query selects the following columns:

*   `PartNumber` from both tables
*   `WC2`, `WC3`, and `WC4` from `AddnlPROC`
*   `Machine` from `AddnlPROC`
*   `RunStd` from `AddnlPROC`
*   Calculated columns: `MthExtHrs` and `DayExtHrs`

### JOIN Clause

The query uses a left join to combine data from both tables. The left join ensures that all records from the `MercoPart` table are included in the results, even if there is no matching record in the `AddnlPROC` table.

```markdown
FROM MercoPart
LEFT JOIN AddnlPROC ON MercoPart.PN = AddnlPROC.PartNumber;
```

### Resultset

The query returns a result set with the specified columns and calculated values. The resultset includes data from both tables, but may contain null values for `AddnlPROC` columns if there is no matching record in `MercoPart`.
