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

### Overview

This SQL query retrieves data from two tables, `Machines` and `[Util Selection C1]`, based on a join condition. It filters the results to include only rows where a specific machine is used.

### Query Components

#### Table Join

The query joins the `Machines` table with the `[Util Selection C1]` table using an outer join (`RIGHT JOIN`). This allows for the inclusion of records from both tables, even if there are no matches in the other table.

#### Join Condition

The join is based on the `PartNumber` column in both tables. This means that each row in the result set will contain data from a single machine and its corresponding usage data.

#### Filtering Condition

The query applies a filter to the results using the `WHERE` clause. The condition `Machines.Prime = -1` is used to select only rows where a specific prime number (-1) is associated with the machine.

### Query Output

The query returns columns from both tables, including:

* `[Util Selection C1].PartNumber`: The part number of the machine.
* `Machines.MachineName`: The name of the machine.
* `[Util Selection C1].USAGE`: The usage data for the part.
* `[Util Selection C1].PartHeight` and `[Util Selection C1].PartWidth`: Dimensions of the part.
* `[Util Selection C1].FirstDim` and `[Util Selection C1].SecDim`: First and second dimensions ( possibly related to geometry or layout) of the part.
* `[Util Selection C1].MetalType`: The type of metal used for the part.

### Implications

The use of an outer join in combination with a filtering condition based on a specific prime number implies that this query is likely being used in a context where machines are assigned a unique identifier (prime number) and usage data is recorded. The filtered results suggest that only certain machines or parts with a specific prime number are being selected for further analysis.

### Example Use Case

This query might be used in a manufacturing or production planning scenario to retrieve specific machine data for analysis, filtering on a particular prime number to focus on key equipment or processes.
