Loading the Database
When we download some db files to the local, we need to do import work if we want to see these db files in mysql.
Loading and Saving Databases
To load a database file, open a command prompt, and change to the directory
that the file is stored in. Then run the following command (replacing
username
and
filename
with the appropriate names):
[Import from local to mysql]
mysql -u username -p (root requires password ) < filename .db
EG：mysql -u root -p < employee.db
Enter the password when prompted for the password after pressing Enter
[Import local from mysql]
To save a database from MySQL to a file, open a command prompt and type the
following (replacing
username
,
databasename
and
filename
with the appropriate
names):
mysqldump -u username -p (root requires a password ) -B databasename > filename .db
Every time there is a new db, it needs to be imported into mysql according to this operation.
