Creating a Database

// Create an in-memory database.
var dbClient = DatabaseClient.Create(opts => {
    opts.Url = ":memory:";
});

Executing SQL Statements

Using direct queries

await dbClient.Execute("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, height REAL)");

Using positional arguments

await dbClient.Execute("SELECT name FROM users WHERE id = ?", userId);

Querying the Database

User ToUser(IEnumerable<Value> row)
{
    var rowArray = row.ToArray();

    if (
        rowArray[0] is Integer { Value: var id } && 
        rowArray[1] is Text { Value: var name } && 
        rowArray[2] is Real { Value: var height }
    {
        return new User(id, name, height);   
    }

    throw new ArgumentException();
}

var result = await dbClient.Execute("SELECT * FROM users");

var users = result.Rows.Select(ToUser);

Closing the Database

dbClient.Dispose();

or with a using statement:

using (var dbClient = DatabaseClient.Create(opts => {
    opts.Url = ":memory:";
}))
{
    // ...
}
