What it does

SQL Code Description

Overview

This SQL query retrieves specific information about the parts from the junk table, grouped by part number. The query calculates and displays various aggregate statistics, including total cost, average cycle time, last dimension values for each part.

Breakdown

SELECT Statement

The SELECT statement specifies which columns to retrieve:

DISTINCTROW junk.PartNumber: Retrieves distinct values of the PartNumber column from the junk table.
Sum(junk.PartCost) AS SumOfPartCost: Calculates the total cost of each part and assigns it an alias SumOfPartCost.
Avg(junk.CycleTime) AS AvgOfCycleTime: Calculates the average cycle time for each part and assigns it an alias AvgOfCycleTime.
Last(junk.FirstDim) AS LastOfFirstDim: Retrieves the last value of the FirstDim column from the junk table for each part and assigns it an alias LastOfFirstDim.
Last(junk.SecDim) AS LastOfSecDim: Retrieves the last value of the SecDim column from the junk table for each part and assigns it an alias LastOfSecDim.

FROM Clause

The FROM clause specifies the table to retrieve data from:

junk: The table containing information about parts.

GROUP BY Clause

The GROUP BY clause groups the retrieved data by a common column:

junk.PartNumber: Groups the data by part number, allowing the calculation of aggregate statistics for each group.

ORDER BY Clause

The ORDER BY clause sorts the final result set in ascending order based on a specific column:

junk.PartNumber: Sorts the result set by part number.

Result Set

The final result set will contain four columns:

Part Number	Sum of Part Cost	Average Cycle Time	Last of First Dim	Last of Sec Dim

Each row represents a unique part, with the corresponding aggregated statistics calculated for that part. The PartNumber column is sorted in ascending order by default.
