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

### Overview

This SQL query retrieves specific data from two joined tables, `Process` and `Metals`, based on a condition applied to the `Metals.PartNo` column. The retrieved columns are modified using string manipulation functions.

### Step-by-Step Explanation

#### 1. Selecting Distinct Row Values

The `SELECT DISTINCTROW` statement is used to retrieve only unique rows from the result set.

#### 2. String Manipulation Functions

Two string manipulation functions are applied to the `PartNumber` column:

*   `Left$([PartNumber],7)`: This function takes the first 7 characters from the left side of the `PartNumber`. The `$` symbol is used to indicate that the function operates on a string.
*   `Right$([PartNumber],1)`: This function takes the last character from the right side of the `PartNumber`.

The resulting strings are assigned aliases as `Expr1` and `Expr2`, respectively.

#### 3. Joining Tables

The query joins the `Process` table with the `Metals` table on the condition that `MetalType` in `Process` equals `PartNo` in `Metals`. This allows the query to access data from both tables based on a common column.

#### 4. Filtering Data

A filter is applied using the `WHERE` clause, which only includes rows where the value of `Metals.PartNo` is equal to `'8110611'`.

#### 5. Sorting Results

The results are sorted in descending order based on both `Left$([PartNumber],7)` and `Right$([PartNumber],1)`. This means that the rows will be ordered first by the last character of the part number (in reverse order), and then by the first 7 characters of the part number.

#### 6. Retrieving Additional Data

The query retrieves additional data from both tables, including:

*   `Metals.PartNo`: The part number of the metal.
*   `Metals.Gauge`: The gauge of the metal.
*   `Metals.Density`: The density of the metal.
*   `Process.PartName`: The name of the process associated with the metal.

### Result

The query will return a list of rows that meet the specified conditions, with the modified `PartNumber` values and additional data from both tables.
