Mysql 您的SQL语法有错误；检查与您的MariaDB服务器版本相对应的手册，以了解使用near''；第23行

我尝试使用以下Mysql查询创建过程，但总是出现错误：

 #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 23

这是我的SQL语句，基本上我希望获取、设置、更新我的数据信息

有人能帮我纠正这个错误吗？

我相信你也缺少了一个括号：

create procedure AddressBook.UpdateContact

。。。应该是：

create procedure AddressBook.UpdateContact(

由于另一个用户提到了分隔符语法，我的只是另一个潜在问题。

PostalCode\u IN）$$$

END$$

应该是

PostalCode\u IN）
结束$$
…在“”附近使用的语法
表示语句结尾（由分隔符标记）出现在不合逻辑的位置。就像这里一样。使用不同的分隔符是令人困惑的：
$
，然后是
$$只需执行
$
。也不需要立即执行所有这些
创建过程。您可以一次做一个，当遇到错误时，这正是您应该做的。它可以帮助你缩小问题的范围。
