Using a named native sql query using xml mapping error

Question

I'm using a named native SQL query using xml mapping, I need to use the mysql function AES_ENCRYPT and AES_DECRYPT but marked me syntax error but do not understand why. Now review it all and is well

I'm using a blob field to store the encrypted data of AES_ENCRYPT

Answer 1

One issue I see there, is the alias of your usuario table. The use could be a keyword for DB engine. If you are using MySQL, check this 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>
