MySQL learning simple notes

mysql command line:

import or run the sql file, run in the bin directory of mysql:

source "pathname"+/mytest_emp_dept.sql;

Export sql file mysqldump -u username -p password database name > export file address;

mysqldump -uroot -pPassword [database name] > [dump file]

Query all table names in the specified database

select table_name from information_schema.tables where table_schema='数据库名' and table_type='base table';

Tables with too much data should retain the table structure, delete the data, and do not want to rebuild the table, you can use:

truncate table [table name];
