我正在使用xml映射的命名本机SQL查询,我需要使用mysql函数AES_ENCRYPT和AES_DECRYPT,但标记了我的语法错误,但不明白为什么。现在回顾一下,很好
我正在使用blob字段存储AES_ENCRYPT的加密数据

ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE use.Correo LIKE 'amezcua92@hotmail.com'' at line 7
答案 0 :(得分:0)
我在那里看到的一个问题是你的usuario
表的别名。 use
可以是数据库引擎的关键字。如果您使用的是MySQL,请查看此9.3. Reserved Words
<sql-query name="finByCorreo" >
<return alias="Usuario" class="Model.TO.Usuario" />
SELECT ut.Correo AS {Usuario.correo},
AES_DECRYPT (ut.Password,'escom') AS {Usuario.password},
ut.Nombres AS {Usuario.nombres},
ut.ApellidoP AS {Usuario.apellidoP},
ut.ApellidoM AS {Usuario.apellidoM}
FROM usuario ut ------------------- here ut instead of use
WHERE ut.Correo LIKE :tags
</sql-query>
