OrderRepository.cs

// Type-safe query — no raw SQL, no strings
var query = new Query()
    .Select([Order.Table["order_id"], Order.Table["customer"], Order.Table["total"]])
    .From(Order.Table)
    .Where(new Criterion<decimal>(Order.Table["total"], ConditionalType.GreaterThan, 100m))
    .OrderBy(Order.Table["created_at"], OrderClauseType.Descending);

// Works identically on every supported database
using var manager = new Manager(connection);
IList<Order> orders = manager
    .Retrieve(query)
    .BindResults<Order>(BindingType.Attribute);
