What it does

SQL Query Description

This SQL query retrieves data from two tables: Machines and [Util Selection C1]. The query performs an inner join on these tables based on the PartNumber column, which is assumed to be common to both tables.

Query Logic

Filter Conditions

The query applies a filter condition to only include rows where the value in the Prime column of the Machines table is equal to -1. This is done using the following conditions:

  • Machines.Prime = -1

This suggests that the query is designed to find parts that are not prime or have an unknown status.

Data Retrieval

The query retrieves the following columns from both tables:

  • [Util Selection C1].PartNumber: The part number of the machine.
  • [Util Selection C1].DESCP: The description of the part.
  • [Util Selection C1].USAGE: The usage of the part.
  • Machines.MachineName: The name of the machine associated with the part.
  • [Util Selection C1].PartSize: The size of the part.

Sorting and Ordering

The query sorts the retrieved data in descending order based on the USAGE column:

  • ORDER BY [Util Selection C1].USAGE DESC

This suggests that the query is designed to prioritize parts with higher usage or more frequently used components.

Example Use Case

This query might be used in a scenario where an organization wants to identify non-prime machine parts with high usage. By applying this filter condition and sorting the results, the query can help maintenance teams prioritize their efforts on machines with the most critical or heavily used components.

Note: The use of [Util Selection C1] as a table alias suggests that the data is part of a larger database schema with a separate table containing machine parts.
