Sqlite3显示数据库、显示表命令[与mysql对比]

注:中括号[]里面为可选项

显示数据库:

sqlite:.database

mysql:show databases;(这个可以没有分号)

切换数据库:

sqlite:帮助并没有说明,应该没有吧,虽然可以附加

mysql: use dbName

显示表:

sqlite:.table [tableName]

mysql:show tables;

显示表结构:

sqlite:select * from sqlite_master where type = “table”;(先设置表头显示,不然你看得会很懵逼,命令为:.header on

mysql:desc tableName;

显示建表语句:

sqlite:.schema [tableName]

mysql: show create table tableName;


退出命令行:

sqlite:.quit / .exit / ctrl+C

mysql:quit / exit
