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

### Overview

This SQL query retrieves data from two tables, `Filtered Parts rstd` and `AddnlPROC`, based on specific conditions and joins them using a LEFT JOIN. The results are filtered to exclude rows where the standardized cost is equal to a specific formatted value.

### Breakdown

#### 1. SELECT Clause

```sql
SELECT [Filtered Parts rstd].*, AddnlPROC.RunStd
```

*   Selects all columns (`*`) from the `Filtered Parts rstd` table and the `RunStd` column from the `AddnlPROC` table.

#### 2. JOIN Clause

```sql
FROM [Filtered Parts rstd] LEFT JOIN AddnlPROC ON (
    ([Filtered Parts rstd].FOPC = AddnlPROC.WC4) AND 
    ([Filtered Parts rstd].FWC3 = AddnlPROC.WC3) AND 
    ([Filtered Parts rstd].FWC2 = AddnlPROC.WC2) AND 
    ([Filtered Parts rstd].PN = AddnlPROC.PartNumber)
```

*   Performs a LEFT JOIN between the `Filtered Parts rstd` and `AddnlPROC` tables.
*   Joins on four columns:
    *   `FOPC` from `Filtered Parts rstd` and `WC4` from `AddnlPROC`.
    *   `FWC3` from `Filtered Parts rstd` and `WC3` from `AddnlPROC`.
    *   `FWC2` from `Filtered Parts rstd` and `WC2` from `AddnlPROC`.
    *   `PN` (Part Number) from `Filtered Parts rstd` and `PartNumber` from `AddnlPROC`.

#### 3. WHERE Clause

```sql
WHERE ((([Filtered Parts rstd].Crstd)\u003c\u003eFormat([RunStd],"0.00000")))
```

*   Filters out rows where the standardized cost (`Crstd`) in the `Filtered Parts rstd` table is equal to a formatted value that represents the same as the `RunStd` value from the `AddnlPROC` table.

#### 4. ORDER BY Clause

```sql
ORDER BY [Filtered Parts rstd].USAGE DESC;
```

*   Orders the results by descending order based on the `USAGE` column in the `Filtered Parts rstd` table.

### Example Use Case

This query is likely used to retrieve a list of parts with their corresponding standardized costs and additional processing information, excluding rows where the standardized cost matches a specific formatted value. The results can be sorted by usage in descending order to prioritize the most commonly used parts.
