How to combine four identical tables in SQL?

Answer from AI
To combine four identical tables in SQL, you can use the UNION ALL operator. It combines the results of multiple queries, including all rows (including duplicates). For example:
SELECT * FROM table1
UNION ALL
SELECT * FROM table2
UNION ALL
SELECT * FROM table3
UNION ALL
SELECT * FROM table4;
If you want to remove duplicates, simply use UNION, but this may be slower as it involves additional sorting and filtering.
