【问题描述】：

我有这个查询，它运行良好并给出了预期的结果。

SELECT count(*) AS total_unsolved,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) = 0 and response_time is null) as today_to_solve,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) > 0 and datediff(deadline, CURTIME()) < 4 and response_time is null) as days_left_1_3,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) > 3 and datediff(deadline, CURTIME()) < 8 and response_time is null) as days_left_4_7,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) > 7 and response_time is null) as mt_week,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) < 0 and datediff(deadline, CURTIME()) > -4 and response_time is null) as overdue_1_3_days,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) < -3 and datediff(deadline, CURTIME()) > -11 and response_time is null) as overdue_4_10_days,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) < -10 and datediff(deadline, CURTIME()) > -30 and response_time is null) as overdue_11_30_days,
    (select count(deadline) from my_table where datediff(deadline, CURTIME()) < -30 and response_time is null) as overdue_mt_month,
    (select count(deadline) from my_table where datediff(deadline, response_time) < 0 and response_time is not null) as solved_with_delay  
 from my_table where response_time is null

我想创建一个在给定时间范围内显示结果的过程。所以我输入了以下内容：

CREATE PROCEDURE status_in_timerange
     (
        IN   start_date                     TiMESTAMP, 
        IN   close_date                     TiMESTAMP,
        OUT  total_unsolved                 INT,  
        OUT  today_to_solve                 INT, 
        OUT  days_left_1_3                  INT, 
        OUT  days_left_4_7                  INT, 
        OUT  mt_week                        INT, 
        OUT  overdue_1_3_days               INT, 
        OUT  overdue_4_10_days              INT,      
        OUT  overdue_11_30_days             INT,    
        OUT  overdue_mt_month               INT,    
        OUT  solved_with_delay              INT    
     )
BEGIN 

    SELECT count(DATEDIFF(deadline, NOW())) AS total_unsolved,
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) = 0 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) > 0 and datediff(deadline, CURTIME()) < 4 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) > 3 and datediff(deadline, CURTIME()) < 8 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) > 7 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) < 0 and datediff(deadline, CURTIME()) > -4 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) < -3 and datediff(deadline, CURTIME()) > -11 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) < -10 and datediff(deadline, CURTIME()) > -30 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, CURTIME()) < -30 and response_time is null and ktimestamp BETWEEN start_date and close_date),
        (select count(deadline) from my_table where datediff(deadline, response_time) < 0 and response_time is not null and ktimestamp BETWEEN start_date and close_date) 

    INTO   total_unsolved , 
           today_to_solve, 
           days_left_1_3, 
           days_left_4_7, 
           mt_week, 
           overdue_1_3_days ,
           overdue_4_10_days,
           overdue_11_30_days,
           overdue_mt_month,
           solved_with_delay

  FROM my_table WHERE response_time is null and ktimestamp BETWEEN start_date and close_date
END ;

很遗憾，此查询显示如下错误：

SQL 错误 (1064)：您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册在第 41 行的“END”附近使用的语法

我已阅读无助于解决问题的相关问题（包括以下内容）。

Mysql stored procedure error

Mysql stored procedure error 1064

附： select version(); 返回 5.6.21

【问题讨论】：

请帮我从存储过程中找出错误
看看inmotionhosting.com/support/website/database-troubleshooting/…
在语句末尾添加分号 (;)：... WHERE response_time is null and ktimestamp BETWEEN start_date and close_date;。
@sForSujit 我浏览了解释错误 1064 的常见情况的文章和视频。但我在存储过程中找不到任何这些错误。如果你能看到，请给我提示
@wchiquito 在此时使用分隔符导致该行出现新错误： SQL 错误（1064）：您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以了解在第 40 行的“附近使用正确的语法
