## What it does
**SQL Code Description**
==========================

### Overview

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

1.  **Selecting first occurrence of cycle time**: It selects the first record from each group based on the `PartNumber`.
2.  **Extracting part number**: It extracts the first 7 characters from the `PartNumber`.
3.  **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.
4.  **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
```sql
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
```sql
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
```sql
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.
