在 Oracle 数据库中，想要查询员工表（EMPLOYEES）中工资（SALARY）高于平均工资的员工信息，以下正确的 SQL 语句是A A SELECT * FROM EMPLOYEES WHERE SALARY > (SELECT AVG(SALARY) FROM EMPLOYEES); B SELECT * FROM EMPLOYEES, (SELECT AVG(SALARY) FROM EMPLOYEES) AS AVG_SALARY WHERE SALARY > AVG_SALARY; C SELECT * FROM EMPLOYEES HAVING SALARY > (SELECT AVG(SALARY) FROM EMPLOYEES); D SELECT * FROM EMPLOYEES WHERE SALARY > AVG(SALARY);
