**SQL Query Description**
==========================

### Overview

This SQL query retrieves data from the `Process` table and performs various string manipulations to extract specific information.

### Query Breakdown

#### 1. SELECT Clause

The `SELECT` clause specifies the columns that will be retrieved from the database. In this case:

*   `Left$([PartNumber],7)`: Extracts the first 7 characters of the `PartNumber` column and returns them as a string. The `$` symbol is used to denote string concatenation in SQL Server.
*   `Trim$(Right$([PartNumber],1))`: Removes the last character (if any) from the `PartNumber` column using the `TRIM` function with the `$` symbol for string concatenation. This effectively extracts the rev number, which is the last digit of the part number.

#### 2. FROM Clause

The `FROM` clause specifies the table that contains the data to be retrieved:

*   `Process`: The table from which to retrieve data.

#### 3. ORDER BY Clause

The `ORDER BY` clause sorts the retrieved data in ascending order based on two columns:

*   `Left$([PartNumber],7)`: The first 7 characters of the part number.
*   `Trim$(Right$([PartNumber],1))`: The last digit (rev number) of the part number. This column is sorted in descending order.

#### 4. AS Clause

The `AS` clause assigns aliases to the extracted columns:

*   `prt`: Alias for the first 7 characters of the part number.
*   `Rev`: Alias for the rev number (last digit of the part number).
*   `PartNumber`: Alias for the original `PartNumber` column.

#### 5. ORDER BY Syntax

The specific syntax used for sorting in this query is an extension to the standard SQL syntax, allowing for sorting on multiple columns with a custom order.

### Example Output

| prt | Rev | PartNumber |
| --- | --- | --- |
| XYZ1234 | 4 | XYZ1234 |
| XYZ1233 | 3 | XYZ1233 |
| ... | ... | ... |

The output will show the first 7 characters of each part number followed by the last digit (rev number) in descending order.
