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

This SQL query retrieves a list of Part Numbers from the `Process` table, filtered by a condition related to prime status on machines.

### Query Breakdown

The query consists of three joins and a conditional filter:

#### Join 1: CntlPanel and CntlPanel4
```sql
CntlPanel LEFT JOIN CntlPanel4 ON CntlPanel.PRDNO = CntlPanel4.pn
```
This join combines the `CntlPanel` table with itself, based on the `PRDNO` column in both tables. The `LEFT JOIN` ensures that all records from `CntlPanel` are included, even if there is no matching record in `CntlPanel4`.

#### Join 2: Process and CntlPanel4
```sql
LEFT JOIN Process ON CntlPanel4.Process.PartNumber = Process.PartNumber
```
This join links the results of the first join with the `Process` table, based on the `PartNumber` column. The `LEFT JOIN` again ensures that all records from `CntlPanel4` are included.

#### Join 3: MachinesQ1 and Process
```sql
LEFT JOIN MachinesQ1 ON Process.PartNumber = MachinesQ1.PartNumber
```
This final join combines the results of the previous two joins with the `MachinesQ1` table, based on the `PartNumber` column. The `LEFT JOIN` preserves all records from the earlier joins.

#### Filter: Prime Status
```sql
WHERE (((MachinesQ1.Prime)=Yes));
```
This filter condition checks for machines where the `Prime` status is `Yes`. Only rows that meet this condition are included in the final result set.

### Result

The query returns a list of Part Numbers from the `Process` table, filtered by the presence of prime status on machines. The result set includes all records from the original `CntlPanel` and `CntlPanel4` tables, linked to the filtered results from the `MachinesQ1` table.

### Example Output

Assuming a sample database:

| CntlPanel | CntlPanel4 | Process | MachinesQ1 |
| --- | --- | --- | --- |
| A123 | A123_1 | X123 | Yes |
| B456 | B456_2 | Y789 | No |
| ... | ... | ... | ... |

The query would return:

* Part Numbers from the `Process` table with prime status on machines:
	+ X123
	+ ... (other part numbers with prime status)
