Mycli是一種使用Python編寫的MySQL命令行接口,它使得在命令行終端操作MySQL數據庫變得更加簡單高效。Mycli具有類似于MySQL shell的交互式界面,同時擁有自動補全,SQL語法高亮和多行輸入等功能。
Mycli的安裝非常簡單,只需要使用pip命令進行安裝即可:
$ pip install mycli
安裝完成后,我們可以使用以下命令來連接到MySQL數據庫:
$ mycli -h hostname -u username -p password database_name
在連接到數據庫后,Mycli提供了許多優秀的功能,例如代碼高亮,自動完成以及SQL歷史記錄。同時,我們可以調用.help命令來查看Mycli中可用的所有命令。例如,在輸入.help之后,我們可以看到以下輸出:
mysql>.help You are using Mycli version 1.21.0 - \? or help: Display this help. - \a or toggle-align: Toggle output alignment. - \G or toggle-grid: Toggle ASCII grid. - \i or \include: Execute commands from a file. - \bye or \quit or exit: Exit. - \l or \list: List all tables in the default catalog/database or the database specified. - \n or \nopager: Disable pager. - \t or \csv or \tsv: Set the output format to tab-separated values or CSV. - \w or \watch: Repeatedly execute a query and watch the results. - ALTER: Alter command for tables. - DELETE: Delete query. - DROP: Drop a database or a table. - GRANT: Grant privileges to user. - INSERT: Insert query. - REFRESH: Flush database changes to disk. - RENAME: Change name of a table. - REVOKE: Revoke privileges from user. - SELECT: Select query. - SET: Change a MySQL global or session variable. - SHOW: Show database or system informaion - TRUNCATE: Truncate a table. - UPDATE: Update query.
總之,Mycli是一種功能強大的MySQL命令行接口,使得在命令行終端進行MySQL數據庫管理變得更加輕松和流暢。
