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

### Overview

This SQL query performs a left outer join on two tables, `[Process by material]` and `Process`, based on the matching values in the `PartNumber` column. The query extracts the first 7 characters from the `PartNumber` column in the `[Process by material]` table and joins it with the corresponding records from the `Process` table.

### Breakdown

*   **SELECT Clause**
    *   `LEFT$([PartNumber],7) AS PN`: This line selects the first 7 characters of the `PartNumber` column from the `[Process by material]` table. The `LEFT$()` function is used to extract a specified number of characters from the beginning of the string. The resulting column is aliased as `PN`.
    *   `Process.*`: This line selects all columns (`*`) from the `Process` table.

*   **FROM Clause**
    *   `[Process by material]`: This line specifies the first table to be queried, which is `[Process by material]`.

*   **JOIN Clause**
    *   `LEFT JOIN Process ON [Process by material].PN = Process.PartNumber`: This line performs a left outer join on the two tables. The join condition is based on the matching values in the `PartNumber` column:
        -   `[Process by material].PN` refers to the aliased `PartNumber` column from the first table.
        -   `Process.PartNumber` refers to the original `PartNumber` column from the second table.

### Result

The result of this query will be a table that includes all records from the `[Process by material]` table, with their corresponding matching records from the `Process` table. The `PN` alias represents the first 7 characters of the `PartNumber` column in the `[Process by material]` table.

### Example Use Case

This query can be used to analyze processes based on part numbers. For instance, it could help identify all processes that have a specific part number or group parts with similar process names.
