Query schemas not known at compile time with Diesel
API Documentation: latest release
Diesel is built to provide strong compile time guarantees that your queries are valid. To do this, it needs to represent your schema at compile time. However, there are some times where you don't actually know the schema you're interacting with until runtime.
This crate provides tools to work with those cases, while still being able to use Diesel's query builder. Keep in mind that many compile time guarantees are lost. We cannot verify that the tables/columns you ask for actually exist, or that the types you state are correct.
The main function used by this crate is
table. Note that you must always
provide an explicit select clause when using this crate.
use diesel_dynamic_schema::table; let users = table("users"); let id = users.column::<Integer, _>("id"); let name = users.column::<Text, _>("name"); users.select((id, name)) .filter(name.eq("Sean")) .first(&conn)
