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

This SQL code snippet performs the following operations on a table named `[SG Trash Query]`:

### 1. Selecting Data

The query selects data from the specified table, including columns `Part`, `PartNumber`, and performing calculations on `PartNumber`.

### 2. Calculating Right-Trimmed Part Number

The code uses the `Right$` function to extract the last character from the `PartNumber` column, and then applies the `Trim$` function to remove any leading or trailing whitespace. The result is stored in a new calculated column named `Rev`.

### 3. Finding Maximum Values

For each group of rows with the same value in the `Part` column, the query uses the `Max` aggregation function to find the maximum values for two columns:

*   `Rev`: The last character of the `PartNumber` column (after right-trimming)
*   `PartNumber`: The original `PartNumber` column

These maximum values are stored in new calculated columns named `Rev` and `MaxOfPartNumber`, respectively.

### 4. Grouping and Sorting Data

The query groups the data by the `Part` column, which means that rows with the same value in this column will be treated as a single group. The results are then ordered based on the values in the `Part` column.

### 5. Returning Results

Finally, the query returns the grouped and sorted data, including the calculated columns `Rev` and `MaxOfPartNumber`, as well as the original `Part` and `PartNumber` columns.

**Key Terms and Functions Used**

*   `SELECT`: The statement used to extract data from a database.
*   `[SG Trash Query]`: A reference to the specified table in the database.
*   `Trim$` and `Right$`: Functions that manipulate strings (i.e., text data).
