In MySQL, there is no MINUS function available for set difference operations. Instead, you can use operators and syntax such as NOT IN, NOT EXISTS, or LEFT JOIN to achieve similar functionality. Here are several methods to implement set difference operations.

  1. Use NOT IN:
SELECT column1
FROM table1
WHERE column1 NOT IN (SELECT column1 FROM table2);
  1. Use NOT EXISTS:
SELECT column1
FROM table1 t1
WHERE NOT EXISTS (SELECT column1 FROM table2 t2 WHERE t1.column1 = t2.column1);
  1. Use a LEFT JOIN:
SELECT t1.column1
FROM table1 t1
LEFT JOIN table2 t2 ON t1.column1 = t2.column1
WHERE t2.column1 IS NULL;

Here are some methods for performing set difference in MySQL. Choose the appropriate method based on your specific requirements and data structure.
