英文:
golang pq sql driver: pq: invalid input syntax for type uuid error type
问题
我正在尝试处理Postgres错误。
如果用户发送了无效的uuid - Postgres会返回一个带有消息的错误：pq: invalid input syntax for type uuid:...
所以，我想检查这个错误，如果错误等于无效的输入语法错误 - 我想显示给客户端404错误，而不是返回服务器错误。
但是我找不到Postgres库中返回的错误的定义错误类型...
有人能告诉我错误是在哪里返回的吗？
英文:
I'm trying to handle Postgres error.
If user sends invalid uuid - Postgres returns an error with message: pq: invalid input syntax for type uuid:...
So, i want to check that error and if the error equals to the invalid input syntax error - i would like to show to the client 404 error, rather than returning server error.
But i can't find the defined error type for the returned error in Postgres library...
Can someone suggest me, where is the error returned?

在查询中，你可以将 uuid 列转换为 text 类型。以下是两种方法：
SELECT * FROM user WHERE id::text = 'sometext'
SELECT * FROM user WHERE text(id) = 'sometext'

PostgreSQL 类型转换的文档在这里：

英文:
In the query you can cast the uuid column to text. Here are two ways to do that:
SELECT * FROM user WHERE id::text = 'sometext'
SELECT * FROM user WHERE text(id) = 'sometext'
