What it does

SQL Query Description

Purpose

This SQL query extracts the part number from a Process table, performs some data manipulation operations on it, and returns the results in a sorted manner.

Breakdown

1. Column Selection

SELECT Left$([Process]![PartNumber],7) AS prt, Max((UCase$(Trim$(Right$([Process]![PartNumber],1))))) AS Rev

The query selects two columns from the Process table:
- Left$([Process]![PartNumber],7): This extracts the first 7 characters from the PartNumber column and assigns it an alias prt.
- Max((UCase$(Trim$(Right$([Process]![PartNumber],1))))) AS Rev: This calculates the maximum value of the uppercased trimmed rightmost character of the PartNumber column. The result is assigned an alias rev.

2. Data Manipulation

FROM Process

The query operates on the Process table.

3. Grouping and Sorting

GROUP BY Left$([Process]![PartNumber],7)
ORDER BY Left$([Process]![PartNumber],7), Max((UCase$(Trim$(Right$([Process]![PartNumber],1))))) DESC;

The query groups the results by the first 7 characters of the PartNumber column (Left$([Process]![PartNumber],7)).
Finally, it sorts the grouped results in descending order based on both the first 7 characters of the PartNumber and the maximum value of the uppercased trimmed rightmost character.

In Summary

This SQL query extracts the part number from a table, calculates a derived column, groups the data, and returns the sorted results. The sorting is done based on two columns: the leftmost 7 characters of the part number and the maximum value of the uppercased rightmost character.
