**SQL Query Description**
|
|
==========================
|
|
|
|
### Overview
|
|
|
|
This SQL query retrieves a list of unique machine details from the `Machines` table, ordered by part number and machine name.
|
|
|
|
### Breakdown
|
|
|
|
#### SELECT Clause
|
|
|
|
```sql
|
|
SELECT DISTINCTROW
|
|
```
|
|
The `DISTINCTROW` keyword is used to ensure that each row returned in the result set contains unique values for all columns specified. This clause eliminates duplicate rows from the result set.
|
|
|
|
#### Columns Specified
|
|
|
|
```sql
|
|
Machines.PartNumber, Machines.MachineName, Machines.CycleTime, Machines.Tool, Machines.Prime
|
|
```
|
|
The query selects specific columns from the `Machines` table:
|
|
|
|
* `PartNumber`: a unique identifier for each machine
|
|
* `MachineName`: the name of the machine
|
|
* `CycleTime`: the time taken by the machine to complete a cycle
|
|
* `Tool`: the tool used in the machine
|
|
* `Prime`: an unknown column ( possibly used as a flag or indicator)
|
|
|
|
#### FROM Clause
|
|
|
|
```sql
|
|
FROM Machines
|
|
```
|
|
The query is executed on the `Machines` table.
|
|
|
|
#### ORDER BY Clause
|
|
|
|
```sql
|
|
ORDER BY
|
|
Machines.PartNumber, Machines.MachineName;
|
|
```
|
|
The result set is ordered by:
|
|
|
|
* `PartNumber`: ascending order (smallest part number first)
|
|
* `MachineName`: ascending order (alphabetical order of machine names)
|
|
|
|
### Purpose and Use Cases
|
|
|
|
This query can be used in various scenarios, such as:
|
|
|
|
* Displaying a list of unique machines with their details
|
|
* Preparing data for further analysis or reporting
|
|
* Filtering out duplicate machines from a large dataset
