**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.
