Question

IN有什么区别和 ANY SQL中的运算符？

Answer 1

SQL>
SQL> -- Use the ANY operator in a WHERE clause to compare a value with any of the values in a list.
SQL>

SQL> -- 您必须在 ANY 之前放置 =、<>、<、>、<= 或 >= 运算符。

SQL> SELECT *
  2  FROM employee
  3  WHERE salary > ANY (2000, 3000, 4000);

对于 In 运算符

SQL> -- Use the IN operator in a WHERE clause to compare a value with any of the values in a list.
SQL> SELECT *
  2  FROM employee
  3  WHERE salary IN (2000, 3000, 4000);

但是对于 IN 运算符，您不能使用 =、<>、<、>、<= 或 >=
