Question

我遇到了自动生成的SQL查询的问题，该查询基于存储在表中的几个较小的查询，并与用户输入的内容相结合。

我将显示有效查询的输入，然后显示查询本身。

然后我会显示我的输入，以及失败的查询。

如果有人可以指出我使用了哪些输入导致我的查询失败，我将非常感激。

fromclause：

((`clients` INNER JOIN `addresstorecord` 
    ON `clients`.`uuid` = `addresstorecord`.`recordid` 
    AND `addresstorecord`.`tabledefid`='tbld:6d290174-8b73-e199-fe6c-bcf3d4b61083' 
    AND addresstorecord.primary='1') 
INNER JOIN `addresses` ON `addresstorecord`.`addressid` = `addresses`.`uuid`)

displayfield：

IF(clients.company != '', 
   CONCAT(clients.company,
          IF(clients.lastname != '' OR clients.firstname != '', 
             CONCAT(' (',
                    IF(clients.lastname != '', clients.lastname, '{blank}'),

Answer 1

您没有使用辅助别名选择字段名称，应该类似

myField as secondary

用表格中的字段替换myField

Answer 2

在失败查询的参数中，“secondaryfield”为空。这就是在“AS secondary”之前被替换的内容，因此结果不是有效的SQL。
