Sqlline - Java

https://github.com/julianhyde/sqlline

star 502

Shell for issuing SQL to relational databases via JDBCIf you have Coursier installed, you can quickly connect to a demo Hypersonic database with:

$ coursier launch sqlline:sqlline:1.12.0 org.hsqldb:hsqldb:2.5.0 net.hydromatic:foodmart-data-hsqldb:0.4 -M sqlline.SqlLine -- -u jdbc:hsqldb:res:foodmart -n FOODMART -p FOODMART -d org.hsqldb.jdbcDriver
0: jdbc:hsqldb:res:foodmart> select avg("shelf_height" * "shelf_width" * "shelf_depth") as "avg_volume" from "product";
+-------------------------+
|       avg_volume        |
+-------------------------+
| 2147.3845245442353      |

Iredis - Python

https://github.com/laixintao/iredis

star 1.8k

Interactive Redis: A Terminal Client for Redis with AutoCompletion and Syntax Highlighting.

Features

  • Advanced code completion. If you run command KEYS then run DEL, IRedis will auto-complete your command based on KEYS result.
  • Command validation. IRedis will validate command while you are typing, and highlight errors. E.g. try CLUSTER MEET IP PORT, IRedis will validate IP and PORT for you.
  • Command highlighting, fully based on redis grammar. Any valid command in IRedis shell is a valid redis command.
  • Human-friendly result display.
  • pipeline feature, you can use your favorite shell tools to parse redis' response, like get json | jq ..
  • Support pager for long output.
  • Support connection via URL, iredis --url redis://example.com:6379/1.
  • Support cluster, IRedis will auto reissue command for MOVED response in cluster mode.
  • Store server configuration: iredis -d prod-redis (see dsn for more).
  • peek command to check the key's type then automatically call get/lrange/sscan, etc, depending on types. You don't need to call the type command then type another command to get the value. peek will also display the key's length and memory usage.
  • Ctrl + C to cancel the current typed command, this won't exit IRedis, exactly like bash behaviour. Use Ctrl + D to send a EOF to exit IRedis.
  • Ctrl + R to open reverse-i-search to search through your command history.
  • Auto suggestions. (Like fish shell.)
  • Support --encode=utf-8, to decode Redis' bytes responses.
  • Command hint on bottom, include command syntax, supported redis version, and time complexity.
  • Official docs with built-in HELP command, try HELP SET!
  • Written in pure Python, but IRedis was packaged into a single binary with PyOxidizer, you can use cURL to download and run, it just works, even you don't have a Python interpreter.
  • Hide password for AUTH command.
  • Says "Goodbye!" to you when you exit!
  • For full features, please see: iredis.io

Or you can download the executable binary with cURL(or wget), untar, then run. It is especially useful when you don't have a python interpreter(E.g. the official Redis docker image which doesn't have Python installed.):

 

wget  https://github.com/laixintao/iredis/releases/latest/download/iredis.tar.gz \
 && tar -xzf iredis.tar.gz \
 && ./iredis

Recently learned about Pgcli after someone recommended it to me on Twitter. Can't imagine myself not using it now when working with PostgreSQL.
