要求兩個表的并集、交集、非交集、差集以及結果集排序,可以使用以下的SQL語句:
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;
請注意,上述語句中的"table1"和"table2"應替換為實際的表名,"column"應替換為實際的列名。另外,排序時可以根據需要選擇升序(ASC)或降序(DESC)。
