SQL UNION and UNION ALL: Everything You Need to Know

How to Combine SQL Query Results: UNION vs UNION ALL [SQL Interview Edition]
Learn how to combine the results of two or more SQL query results into one using the UNION and UNION ALL SQL set operators. This video tutorial will show you how to use these operators to create a single result set that contains all of the data from the original tables, either with or without duplicates.
The UNION operator combines the results of two or more SELECT statements and removes any duplicate rows. The UNION ALL operator also combines the results of two or more SELECT statements, but it does not remove any duplicate rows.
