What it does

SQL Code Description

Overview

This SQL code transforms the Machines table by performing several operations:

Selecting first occurrence of cycle time: It selects the first record from each group based on the PartNumber.
Extracting part number: It extracts the first 7 characters from the PartNumber.
Identifying primary machine: It identifies the maximum value in the MachineName column for each PartNumber, considering only records where [Prime] = TRUE. If no such record exists, it returns an empty string.
Calculating standard time: It calculates the maximum cycle time for each PartNumber and formats it as a decimal value with two places.

Detailed Breakdown

First Section: SELECT Statement

SELECT 
    Machines.PartNumber,
    Left([PartNumber],7) AS Part,
    Max(IIf([Prime],[MachineName])) AS PrimaryMachine,
    Format(Max(IIf([Prime],[Cycletime])), "0.0") AS StdTime
FROM 
    Machines
GROUP BY 
    Machines.PartNumber

This section selects the required columns from the Machines table.
It groups the results by the PartNumber.
The Left([PartNumber], 7) function extracts the first 7 characters from the PartNumber.

Second Section: TRANSFORM Statement

TRANSFORM 
    First(Machines.CycleTime) AS FirstOfCycleTime

This section transforms the results by selecting the first occurrence of CycleTime for each group based on the PartNumber.

Final Section: PIVOT Statement

PIVOT 
    Machines.MachineName;

This section pivots the results, rotating the columns to match the unique values in the MachineName column.

Result

The final result is a table with the following structure:

Part	Primary Machine	Std Time
...	...	...

Each row represents a part number, and the columns contain the extracted part number, primary machine name, and standard time value. The PrimaryMachine column contains the maximum machine name for each part number where [Prime] = TRUE, and the StdTime column contains the formatted maximum cycle time for each part number.
