Description

sqlite is a thin wrapper for the SQLite library, which in turn is "a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine."

Install SQLite Dependency

Before you can use this module, you must first have the SQLite development library installed on your system.

Fedora 31:

sudo dnf -y install sqlite-devel

Ubuntu 20.04:

sudo apt install -y libsqlite3-dev

Windows:

• Download the source zip from SQLite Downloads
• Create a new sqlite subfolder inside v/thirdparty
• Extract the zip into that folder

Performance Tips

When performing a large amount of database calls (i.e. INSERTS), significant performance increase can be obtained by controlling the synchronization and journal modes.

For instance:

import db.sqlite

db := sqlite.connect('foo.db') or { panic(err) }
db.synchronization_mode(sqlite.SyncMode.off)!
db.journal_mode(sqlite.JournalMode.memory)!
