Sorting Results from Combined Subqueries (UNION)
Combining data from multiple subqueries using UNION
allows for sorting the final result set.
Scenario:
Let's say you have a query combining data from multiple subqueries.
Problem:
How do you sort the combined results?
Incorrect Approach:
Using OR
instead of UNION
to combine subqueries will prevent proper ordering of the complete dataset.
Solution:
To sort the combined results, add an ORDER BY
clause to the end of your UNION
query. This clause will affect the entire combined result set.
For example, to sort by the name
column: (The specific query structure will need to be provided to give a complete, accurate example) The provided text lacks a complete, functional example query using UNION. A complete example would be needed to illustrate the solution.
