无法更新Mysql中的数据

Question

我正在尝试更新 Mysql 中的数据或更新（如果存在）但我收到此错误：

#1064 - 您的 SQL 语法有错误；查看与您的 MySQL 服务器版本相对应的手册，了解在 'delimiter; 附近使用的正确语法；
调用 insertIfNotNull((SELECT checkin_id FROM `_9' at line 1

这是我用来更新或插入数据的查询：

DROP FUNCTION IF EXISTS insertIfNotNull;                    
delimiter $$                                        
create function insertIfNotNull(checkin int(11))                     
returns int                     
BEGIN                         
   IF checkin IS NOT NULL THEN                              
      UPDATE `_914_table_checkin` SET clock_in = '2021-6-15 12:09:20', break_in = 'null', break_out = 'null', clock_out = '2021-6-15 12:09:41' WHERE checkin_id = checkin ;                        
   ELSE                             
      INSERT INTO `_914_table_checkin` (company_id, manager_id, worker_id, added_by, clock_in, break_in, break_out, clock_out, date) VALUES (4,214,225,'manager','2021-6-15 12:09:13','null','null','2021-6-15 12:09:34','2021-6-15');
   end if;
   return 2;                     
END                    
$$                    
delimiter;
call insertIfNotNull((SELECT checkin_id FROM `_914_table_checkin` WHERE company_id = 4 AND manager_id = 214 AND worker_id = 214 AND date = '2021-6-15'))

Answer 1

您在最后一行错误地输入了_914_tabela_checkin。应该是：

call insertIfNotNull((SELECT checkin_id FROM `_914_table_checkin` WHERE company_id = 4 AND manager_id = 214 AND worker_id = 214 AND date = '2021-6-15'))
