laravel/lumen查询构建器中的问题whereColumn方法 [英] Issue in laravel/lumen query builder whereColumn method

问题描述

• 流明版本:5.5
• PHP版本:7.0

我编写了以下代码，以使用whereColumn方法更新数据:

I wrote following code to update data by using whereColumn method:

Ratings::whereColumn([['class_id', '=', $class_id], ['id', '=', $rating_id]])->update(['grade' => $grade, 'star' => $star, 'comment' => $comment]);

会产生SQL错误:

SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'where clause' (SQL: update \`ratings\` set \`grade\` = 16级学生, \`star\` = 4, \`comment\` = very good where (\`class_id\` = \`1\` and \`id\` = \`6\`))

似乎正确的SQL命令应使用引号''而不是``

it seems that the correct SQL command should use quote '' instead of ``

有人可以帮我解决这个问题吗?

Can someone help me solve this problem?

推荐答案

根据文档

whereColumn方法可用于验证两列是否相等

The whereColumn method may be used to verify that two columns are equal

因此，它尝试比较列 class_id 并假设1为列，请参阅1前后的引号

Therefore it tries to compare column class_id with assuming 1 as a column see back-ticks around 1

代替使用 where 函数

Ratings::where([['class_id', '=', $class_id], ['id', '=', $rating_id]])
        ->update(['grade' => $grade, 'star' => $star, 'comment' => $comment]);
