解释原因以及可能的解决方案

Question

我有一个列

的表 postgres上的

True muringa Traceback (most recent call last): File "door_code_final_calib_dig_2.py", line 352, in <module> arabica = delay_for_goodant(data) NameError: name 'data' is not defined table.decimal('some_column', 30,15)

当我从节点运行numeric(30,15)时，我得到的行响应如下：

knex.raw('select some_column from some_table')

我真正指出的是，我做了类似于firstValue＆gt; lastValue的事情，我最后得到了一个真实的回复，这让我觉得这些都是以字符串而不是数字的形式返回。

是否可以覆盖此行为？

您可以查看pg-types模块使用的pg模块，该模块由2017-08-08 14:36:20,097 WARN org.apache.xml.security.signature.XMLSignature.checkSignatureValue:724 - Signature verification failed.

您可以在这里找到 https://github.com/brianc/node-pg-types/blob/master/lib/builtins.js

使用示例：

const pg = require('pg');

pg.types.setTypeParser(pg.types.builtins.INT8, (value: string) => {
   return parseInt(value);
});

pg.types.setTypeParser(pg.types.builtins.FLOAT8, (value: string) => {
    return parseFloat(value);
});

pg.types.setTypeParser(pg.types.builtins.NUMERIC, (value: string) => {
    return parseFloat(value);
});

knex postgres返回数值/小数值的字符串
