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

### Overview

This SQL query performs a left join operation to combine data from two tables, `[Filtered Parts 3]` and `UniversalQ`, based on the matching `PartNumber` field.

### Query Breakdown

#### SELECT Clause

The `SELECT` clause specifies the columns to be retrieved from both tables:

* `[Filtered Parts 3].PN`: The `PartNumber` column from the `[Filtered Parts 3]` table.
* `[Filtered Parts 3].ACTIV`: The `ACTIV` column from the `[Filtered Parts 3]` table.
* `[Filtered Parts 3].USAGE`: The `USAGE` column from the `[Filtered Parts 3]` table.
* `UniversalQ.MetalType`: The `MetalType` column from the `UniversalQ` table.
* `UniversalQ.PartName`: The `PartName` column from the `UniversalQ` table.
* `[Filtered Parts 3].ITTYP`: The `ITTYP` column from the `[Filtered Parts 3]` table.
* `UniversalQ.PartSize`: The `PartSize` column from the `UniversalQ` table.

#### FROM and JOIN Clauses

The query specifies the two tables to join:

* `[Filtered Parts 3]`: The first table, which is likely a temporary or staging table containing filtered data.
* `UniversalQ`: The second table, which contains additional information about each part.

The `LEFT JOIN` clause performs a left outer join operation between the two tables based on the matching `PartNumber` field. This means that all records from `[Filtered Parts 3]` will be included in the results, even if there is no matching record in `UniversalQ`.

#### INTO Clause

The `INTO` clause specifies the alias for the resulting table:

* `[Process by List]`: The temporary table into which the combined data will be written.

### Example Output

The query will produce a table with the specified columns, containing all records from `[Filtered Parts 3]`, along with the corresponding information from `UniversalQ`. If there is no matching record in `UniversalQ` for a particular `PartNumber` in `[Filtered Parts 3]`, the resulting table will contain null values for the columns from `UniversalQ`.
