# SQLite Koans

Companion code for [SQLite Koans](https://mblum.me/2023/01/sqlite-koans/)

This project configures `sqlite3` for real world apps:

✅ Foreign Keys

✅ Read as you Write

✅ Write-Ahead Logging

✅ `UTF-8` encoding

✅ graceful table lock error handling via `PRAGMA busy_timeout;`

✅ No empty or `null` primary keys

✅ WAL backup via checkpointing

The repo has a commit covering each koan that we tie to a particular `PRAGMA` config flag:

[SQLite PRAGMA](https://www.sqlite.org/pragma.html)

## Depends On

[SQLite Version 3.40.1](https://www.sqlite.org/releaselog/3_40_1.html)

> Ubuntu apt version is outdated on both Ubuntu 20 and 22

## Build SQLite from source

1\. Install Build Tools

> `gcc` is required for `CGO` bindings used by `mattn/go-sqlite3`

`sudo apt-get install build-essential gcc`

1a\. confirm `gcc` installation

`gcc --version`

2\. Install latest SQLite snapshot (~v3.40.1 minimum)

```

export SQLITE_SNAPSHOT=202301131932

wget "https://www.sqlite.org/snapshot/sqlite-snapshot-${SQLITE_SNAPSHOT}.tar.gz"

tar -xzvf sqlite-snapshot-$SQLITE_SNAPSHOT.tar.gz

cd sqlite-snapshot-$SQLITE_SNAPSHOT

./configure

make

sudo make install

```

3\. Verify `sqlite3` install

```
