What it does
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
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
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 machineMachineName
: the name of the machineCycleTime
: the time taken by the machine to complete a cycleTool
: the tool used in the machinePrime
: an unknown column ( possibly used as a flag or indicator)
FROM Clause
FROM Machines
The query is executed on the Machines
table.
ORDER BY Clause
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
