sql存储过程Quotes（）

Question

我需要在存储过程中生成这样的字符串。

select case when Sex like '%' then 'Person' end as Sex from tableName;

在存储过程中，我已经这样生成。

select case when Sex like quote(%) then quote(Person) end as Sex from tableName;

我得到的错误是

    Error Code: 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 '%) then quote(Person) end as Sex from tableName' at line 1   0.000 sec

我的MariaDB版本是'10 .3.16-MariaDB'

请帮助解决此问题。

您没有在第二个查询中引用文字。试试：

SELECT CASE
         WHEN sex LIKE quote('%') THEN
           quote('Person')
       END AS sex
       FROM tablename;
