## What it does
**SQL Query Description**
=====================================
### Overview
This SQL query retrieves a list of press brake data from the `PressBrakes` table, filtered by a specific condition related to the `CNC` column. The results are then ordered in descending order by the `PBType` column.
### Breakdown
#### SELECT Clause
-------------------
```markdown
SELECT PressBrakes.PressBrake,
PressBrakes.PBType,
PressBrakes.CNC,
PressBrakes.WC2,
PressBrakes.WC3,
PressBrakes.WC4
```
This clause specifies the columns to be retrieved from the `PressBrakes` table. The selected columns include:
* `PressBrake`: the press brake data
* `PBType`: the type of press brake
* `CNC`: the CNC information
* `WC2`, `WC3`, and `WC4`: additional values ( likely related to work codes or specifications)
#### WHERE Clause
------------------
```markdown
WHERE (((PressBrakes.CNC)=[Forms]![14" Process Sheet]![txtPrime] Or
(PressBrakes.CNC) Is Null Or (PressBrakes.CNC)="ALL"))
```
This clause filters the data based on the value of the `CNC` column. The condition checks for the following:
* If the `CNC` value is equal to a specific string (`[Forms]![14" Process Sheet]![txtPrime]`) or
* If the `CNC` value is Null or
* If the `CNC` value is equal to `"ALL"`
The `[...]` notation suggests that these values are being retrieved from a form or dialog box in an application, possibly related to process sheets.
#### ORDER BY Clause
---------------------
```markdown
ORDER BY PressBrakes.PBType DESC;
```
This clause sorts the results in descending order by the `PBType` column. This means that the press brake types will be listed in reverse alphabetical order (Z-A).
### Example Use Case
This query is likely used to retrieve a list of press brake data for a specific process or project, filtered by the CNC information. The sorted results can help identify the most common or frequently used press brake types.
