如何在knex中添加两个绑定参数? [英] How to add two bind params in knex?

问题描述

我正在从数据库中选择内容，我必须使用2个绑定参数.在使用一个参数的情况下，它起作用，但是在使用两个参数的情况下，我收到此错误在编译RAW查询时检测到未定义的绑定"错误，并在nodejs控制台中显示预期的1个绑定，看到了2个".

I'm traying to select something from database and I have to use 2 bind params. With one param it works but with two i get this error "Undefined binding(s) detected when compiling RAW query" error and "Expected 1 bindings, saw 2" in nodejs console.

如何使用第二绑定参数?

How to use 2nd bind param?

有效的代码:

knex.with('with_alias', knex.raw('select * from "lyrics" where "for_id" = "1" and "var" = ?', var)).select('*').from('with_alias')

我也尝试过，但是没有用

I also tried but it didn't worked

knex.with('with_alias', knex.raw('select * from "lyrics" where "for_id" = ? and "var" = ?', var1, var2)).select('*').from('with_alias')

感谢您的帮助，对不起，英语不好！

Thanks for help and sorry for bad english!

推荐答案

尝试在数组中传递两个变量:

Try to pass two variables in an array:

knex.with('with_alias', knex.raw('select * from "lyrics" where "for_id" = ? and "var" = ?', [var1, var2])).select('*').from('with_alias')

应该可以.
