来个Oracle数据库版本的merge into

好的，以下是Oracle数据库版本的"merge into"语句示例：

MERGE INTO employees e
USING (
  SELECT employee_id, first_name, last_name, email, phone_number, hire_date, job_id, salary, commission_pct, department_id
  FROM employees_temp
) t
ON (e.employee_id = t.employee_id)
WHEN MATCHED THEN
  UPDATE SET e.first_name = t.first_name, e.last_name = t.last_name, e.email = t.email,
             e.phone_number = t.phone_number, e.hire_date = t.hire_date, e.job_id = t.job_id,
             e.salary = t.salary, e.commission_pct = t.commission_pct, e.department_id = t.department_id
WHEN NOT MATCHED THEN
  INSERT (e.employee_id, e.first_name, e.last_name, e.email, e.phone_number, e.hire_date,
          e.job_id, e.salary, e.commission_pct, e.department_id)
  VALUES (t.employee_id, t.first_name, t.last_name, t.email, t.phone_number, t.hire_date,
          t.job_id, t.salary, t.commission_pct, t.department_id);

在这个示例中，我们将"employees_temp"表中的数据更新或插入到"employees"表中。连接条件是"employee_id"列相等。如果匹配，则更新"employees"表中的数据；如果不匹配，则插入一条新的记录。请注意，这是一个基本的示例，您可以根据自己的需求修改它。
