How do I import .sql files into SQLite 3?
From a sqlite prompt:
sqlite> .read db.sql
Or:
cat db.sql | sqlite3 database.db
Also, your SQL is invalid - you need ;
on the end of your statements:
create table server(name varchar(50),ipaddress varchar(15),id init);
create table client(name varchar(50),ipaddress varchar(15),id init);
How to import a .sql file into DuckDB database?
As I couldn’t edit my answer above:
I had a brief look into the download you referred to.
According to the screenshots included in the zip-download it seems to be a MySQL database dump file (as the tool shown in the screenshots is MySQL Workbench).
DuckDB import/export function supports its own structure and format of a dump.
With the above mentioned extension duckDB can access SQLite database files directly. With another extension PostgreSQL is also supported, but currently no support of MySQL.
In Python you could use Mysqldump to access the file and save the tables as dataframes.
DuckDB can query such dataframes directly.
If you prefer, with a GUI such as dbeaver, you can also access the MySQL dump file and copy the tables to a duckDB database file.

An alternative method that would work nicely but is rarely mentioned is: use an ORM class that abstracts specific database differences away for you. e.g. you get these in PHP (RedBean), Python (Django's ORM layer, Storm, SqlAlchemy), Ruby on Rails (ActiveRecord), Cocoa (CoreData)
i.e. you could do this:
- Load data from source database using the ORM class.
- Store data in memory or serialize to disk.
- Store data into destination database using the ORM class.
