MySQL在创建存储过程的时候,语法正确却提示You have an error in your SQL syntax

　　我在使用MySQL工具编写MySQL存储过程的时候,明明语法正确,但是却一直提示You have an error in your SQL syntax。

　　比如下面一段代码

 CREATE PROCEDURE demo_pro()
 BEGIN
     DECLARE doned BOOLEAN;
     DECLARE addr varchar(20);
     DECLARE demo_cur CURSOR FOR SELECT detail from address;
     DECLARE CONTINUE HANDLER FOR NOT FOUND SET doned = True;
     SET doned = False;
     OPEN demo_cur;
     demo_cur:LOOP
         FETCH demo_cur into addr;
         IF doned THEN
             LEAVE demo_cur;
         ELSE
             insert into demo(demo_value) values(addr);
         END IF;
     END LOOP;
     CLOSE demo_cur;
 END;

　　找了半天才找到解决方案,原来不是语法的错误，是MYSQL语法解析器的原因。MYSQL 解析器解析遇到“;”分号，就结束本次执行，所以就造成了很多语法错误。解决方案是:

 DELIMITER |  #结束符号,可以根据自己的需求,改成 $也可以
 CREATE PROCEDURE demo_pro()
 BEGIN
     DECLARE doned BOOLEAN;
     DECLARE addr varchar(20);
     DECLARE demo_cur CURSOR FOR SELECT detail from address;
     DECLARE CONTINUE HANDLER FOR NOT FOUND SET doned = True;
     SET doned = False;
     OPEN demo_cur;
     demo_cur:LOOP
         FETCH demo_cur into addr;
         IF doned THEN
             LEAVE demo_cur;
         ELSE
             insert into demo(demo_value) values(addr);
         END IF;
     END LOOP;
     CLOSE demo_cur;
 END;|
 DELIMITER ;
