**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.
