要求两个表的并集、交集、非交集、差集以及结果集排序,可以使用以下的SQL语句:
SELECT * FROM table1
UNION
SELECT * FROM table2;
SELECT * FROM table1
INTERSECT
SELECT * FROM table2;
SELECT * FROM table1
EXCEPT
SELECT * FROM table2;
SELECT * FROM table1
LEFT JOIN table2 ON table1.column = table2.column
WHERE table2.column IS NULL;
SELECT * FROM table1
ORDER BY column ASC/DESC;
请注意,上述语句中的"table1"和"table2"应替换为实际的表名,"column"应替换为实际的列名。另外,排序时可以根据需要选择升序(ASC)或降序(DESC)。
