**SQL Update Statement Description**
=====================================

### Overview

This SQL update statement modifies the values in two tables: `filter3a` and `[RMSFILES#_DANNYF]`. The update is performed through a join between these two tables, which allows for filtering and manipulation of data based on matching conditions.

### Breakdown

#### Join Clause
-----------------

The statement starts with an inner join clause:
```sql
INNER JOIN [RMSFILES#_DANNYF] ON filter3a.Part = [RMSFILES#_DANNYF].PRDNO
```
This joins the `filter3a` table with the `[RMSFILES#_DANNYF]` table on a matching condition: `Part` in `filter3a` equals `PRDNO` in `[RMSFILES#_DANNYF]`. This allows for selecting rows from both tables that meet this condition.

#### Update Clause
-----------------

The update clause modifies the values in the joined tables:
```sql
SET [RMSFILES#_DANNYF].NEWNET = Format([ActualWt],"#.000"), 
     [RMSFILES#_DANNYF].NEWGRS = Format([GrossWt],"#.000");
```
This updates two columns in the `[RMSFILES#_DANNYF]` table:

1. `NEWNET`: sets its value to the result of formatting `[ActualWt]` with a comma and two zeros (e.g., 123.456 becomes 123,000).
2. `NEWGRS`: sets its value to the result of formatting `[GrossWt]` with a comma and two zeros (e.g., 1000 becomes 1,000).

#### Format Function
-------------------

The `Format()` function is used to format the values of `[ActualWt]` and `[GrossWt]`. The first argument to `Format()` is the value to be formatted, and the second argument is a template string that specifies the format.

In this case, the template string `"#.000"` means:

* `#`: format as a decimal number
* `.`: use a comma as the decimal separator (if specified by the locale)
* `000`: pad with zeros to three digits

By formatting `[ActualWt]` and `[GrossWt]` in this way, the resulting values are displayed with commas separating thousands, which is likely a common convention for weight or quantity measurements.

### Example Use Case
--------------------

This update statement might be used in a database management system where:

* `filter3a` contains filter criteria for a data set
* `[RMSFILES#_DANNYF]` contains additional information about the filtered items, such as weights and quantities
* The `NEWNET` and `NEWGRS` columns need to be updated with formatted values based on the actual weight or quantity

By applying this update statement, the formatted values for `NEWNET` and `NEWGRS` can be calculated and stored in the `[RMSFILES#_DANNYF]` table, providing a consistent display of weights and quantities.
