FROM Machines_Crosstab RIGHT JOIN [Process by List] ON Machines_Crosstab.PartNumber = [Process by List].PN
ORDER BY [Process by List].USAGE DESC;

```

## Parameters
- *None*
## What it does
**SQL Query Description**
=========================

### Overview

This SQL query retrieves data from two tables: `Machines_Crosstab` and `[Process by List]`. It performs a right outer join on these tables based on the `PartNumber` column, which is common to both tables. The resulting data is then ordered in descending order based on the `USAGE` column of the `[Process by List]` table.

### Breakdown

#### Query Structure
```sql
SELECT 
  [Process by List].USAGE, 
  [Process by List].PartName, 
  Machines_Crosstab.*
FROM 
  Machines_Crosstab 
RIGHT JOIN 
  [Process by List] 
ON 
  Machines_Crosstab.PartNumber = [Process by List].PN
ORDER BY 
  [Process by List].USAGE DESC;
```
#### Join Type

The `RIGHT JOIN` clause is used to join the two tables. In a right outer join, all rows from both tables are returned, with NULL values in the columns of one table where there are no matches.

#### Table Columns

* `[Process by List]`: The table containing process data.
	+ `.USAGE`: The column containing usage data for each process.
	+ `.PartName`: The column containing part names associated with each process.
* `Machines_Crosstab`: The table containing machine data.
	+ `.*`: All columns of the `Machines_Crosstab` table are included in the query results.

#### Join Condition

The join is performed on the `PartNumber` column, which is common to both tables. This ensures that only rows with matching part numbers from both tables are included in the results.

#### Ordering

Finally, the query is ordered by the `USAGE` column of the `[Process by List]` table in descending order (highest usage first).
