Question

我是oracle的新手，我想更新列id = 1 , 2中的多个行值。

我试过了：

update Tester 
set employee_phone_number = ( 0789456123,0789456321)  
where employee_id in (1,2);

但它给了我“缺少右括号”

任何帮助，请提前感谢。

另一种方法：

merge into
  tester
using (
  select 1 id,'0123456785' employee_phone_number from dual union all
  select 2 id,'0123456786' employee_phone_number from dual) new_values
on (
  tester.id = new_values.id)
when matched then update 
  set employee_phone_number = new_values.employee_phone_number;

更多的单词，但允许仅在一个地方指定值，并扩展为允许id尚不存在的插入。

Answer 2

请改为尝试：

update Tester 
set employee_phone_number = CASE WHEN employee_id = 1 THEN 0789456123
                                 WHEN employee_id = 2 THEN 0789456321
                            END
where employee_id in (1,2);

Oracle更新多行值，其中id列等于特定值
