【中文标题】错误代码：1054。“字段列表”中的未知列

【英文标题】：Error Code: 1054. Unknown column in 'field list'

【发布时间】：2016-02-09 01:32:07

【问题描述】：

请帮助我正在尝试执行以下存储过程。我收到一条错误消息，指出“bpc2016.entity”。当我在行业CY 视图中删除对行业PY 的引用时，错误消失了。请帮助表和列存在于数据库中。

CREATE DEFINER=`root`@`localhost` PROCEDURE `getAbudgetnow`()

CREATE OR REPLACE VIEW industryPY
AS
SELECT
alet.area AS 'area',
alet.industry_description AS 'industry_desc',
alet.industry AS 'industry',

ref_data.pz AS 'pz',
ref_data.rate AS 'amount'
FROM
alet
RIGHT JOIN
ref_data ON (alet.industry = ref_data.industry and alet.area = ref_data.area)
WHERE alet.industry IS NOT NULL;

【问题讨论】：

错误信息很清楚 - 它不能引用字段 bpc2016.entity。您应该发布 bpc2016

的创建表语句

bpc 2016 表已经存在于带有数据的数据库中

@the_big_blackbox ：但它似乎没有实体字段...显示表定义。

另外 mysql 也没有 FULL JOIN 至少不是直接

大家好，包括表定义

【参考方案1】：

感谢所有帮助，这似乎是问题所在 - 当我将完整连接替换为 right 或 left join 时，Mihai 是正确的“mysql 没有 FULL JOIN 至少不是直接的”。程序执行。

【参考方案2】：

您可以重新定义分隔符，以便告诉解析器语句在您的过程中的何处结束；
