我正在将此程序创建为地域。 当我运行时，它给我错误
call geographical("VESTAS",null,null,null,null,null,null,null,null);
错误1064（42000）：您的SQL语法有错误；请查看与您的MySQL服务器版本相对应的手册，以在第1行的'NULL'附近使用正确的语法
我还编写了另一个过程，其中引号中没有语句，这给了我一个空集。
答案 0 :(得分：0)
您要将null隐含为字符串，这将导致null。 例如，存在CONCAT（'“'，appl_name2，'”'），其中appl_name2为null，这将导致结果为null，而不是“ null”（字符串）。
您可以尝试这样做以更好地理解：
select concat('first',null,'second');
我建议您使用COALESCE函数，例如：
select concat('first',coalesce(appl_name2,'NULL','notnull'),'second');
答案 1 :(得分：0)
没有理由让您在存储过程中使用准备好的语句。这样会使过程更难于编写/读取/维护，并且更容易出错。
在该过程中使用直接SQL，因此还可以避免在连接NULL值时出现问题。
