问题描述

我从节点应用程序收到一个 [错误:关系原因不存在] 错误。该关系确实存在,我不确定是什么问题。

I am getting a [error: relation "causes" does not exist] error from my node app. The relation does exist, I'm not sure what the problem is.

我创建的表是

CREATE TABLE causes (

cause_id bigint NOT NULL default nextval('causes_cause_id_seq'::regclass),
cause_name varchar(40) NOT NULL,
goal integer,
sponsor varchar(30),
organization varchar(30),
submitter varchar(30),
address varchar(34),
balance numeric

);

这是给出错误的查询:

client = pg.connect(connectionString, function(err, client, done){
    if(err) console.log(err);

    client.query('INSERT INTO causes (cause_name, goal, organization, sponsor, submitter) VALUES ($1,$2,$3,$4,$5) RETURNING *', r, function(err, result){
    if(err) console.log(err);
    });
});


推荐答案

在您的客户端之前。 query('INSERT ...')调用,运行以​​下命令以确保您的关系在当前连接上可访问:

Directly before your client.query('INSERT...') call, run the following to ensure that your relation is accessible on the current connection:

client.query('SELECT * FROM pg_catalog.pg_tables', function(err, result) {
  console.log(result);
});

如果看不到原因结果之间的关系,那么要么该关系不存在,要么是在其他用户下创建的。

If you don't see your causes relation among the results, then either the relation doesn't exist, or it was created under a different user.
