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

### Overview

This SQL query retrieves specific information from the `PressBrakes` table in a database. It filters data based on certain conditions and sorts the results by the value of the `PBType` column in descending order.

### Breakdown

#### SELECT Clause
```markdown
SELECT PressBrakes.PressBrake, PressBrakes.PBType, PressBrakes.CNC, PressBrakes.WC2, PressBrakes.WC3, PressBrakes.WC4
```
* The query selects six columns (`PressBrake`, `PBType`, `CNC`, `WC2`, `WC3`, and `WC4`) from the `PressBrakes` table.

#### FROM Clause
```markdown
FROM PressBrakes
```
* The query specifies the `PressBrakes` table as the data source.

#### WHERE Clause
```markdown
WHERE (((PressBrakes.CNC)=[Forms]![Process Sheet]![txtPrime] Or (PressBrakes.CNC) Is Null Or (PressBrakes.CNC)="ALL"))
```
* The query filters data based on three conditions:
	1. `PressBrakes.CNC` is equal to the value in the `txtPrime` field of the `Process Sheet` form.
	2. `PressBrakes.CNC` is null.
	3. `PressBrakes.CNC` is equal to the string "ALL".
* The condition is implemented using an OR operator, which allows the query to return rows that meet any one of these conditions.

#### ORDER BY Clause
```markdown
ORDER BY PressBrakes.PBType DESC;
```
* The query sorts the filtered results in descending order by the value of the `PBType` column.

### Example Use Case

This SQL query is likely used in a manufacturing or production environment to retrieve information about brake types, cnc settings, and other parameters related to press brakes. For example:

* A production manager might use this query to view the most common brake types used on a particular machine.
* A quality control specialist might use this query to identify which brake types have been used in the production of defective parts.

Note that the `[Forms]![Process Sheet]!txtPrime` part suggests that this query is being executed within a Visual Basic for Applications (VBA) environment, possibly as part of an Excel spreadsheet or other application.
