Question

我正试图在heroku终端上检测我的数据库，如下所示：

myapp@ubuntu:~/RubymineProjects/myapp$ heroku pg:info
The plugin heroku-sql-console has been deprecated. Would you like to remove it? (y/N) n
=== HEROKU_POSTGRESQL_JADE_URL (DATABASE_URL)
Plan:        Dev
Status:      available
Connections: 1
PG Version:  9.1.6
Created:     2012-10-10 19:59 UTC
Data Size:   9.1 MB
Tables:      32
Rows:        2802/10000 (In compliance)
Fork/Follow: Unsupported

所以，我试过了：

myapp@ubuntu:~/RubymineProjects/myapp$ heroku pg:psql
The plugin heroku-sql-console has been deprecated. Would you like to remove it? (y/N) n
psql (9.1.7, server 9.1.6)
SSL connection (cipher: **-**-****-**, bits: 256)
Type "help" for help.

我需要列出所有用户记录：

dbfjinfaes61gb=> select * from users
dbfjinfaes61gb->

但是上面，没有发生任何事，我在这里缺少什么？

Answer 1

在查询结尾处需要分号：

select * from users;

Answer 2

运行此

heroku pg:psql -c "command" --app "name-app"

样品

heroku pg:psql -c "\?" --app app-sample

如何在heroku中使用pg：psql？
