Std.Db.Query.Shape.select
fn
select: &Std.Db.Query.Shape.Select -> Result[Std.Db.Query.Statement, Std.Db.Query.QueryError]This is a callable function.
What it does
A whole query as a statement, or the first thing wrong with it.
The clauses are written in the order the language reads them, so what is
built is what runs rather than something a server has to be lenient about.
Everything that could be a name is checked here, in one place, rather than
at each of the calls that put the query together.
Read the signature
- The text after the name is the type checked by Pudu.
- Read arrows from left to right: inputs come first, and the final type is returned.
- & borrows a value for this call instead of moving or copying it.
- Names inside [ ] are type arguments, such as the item type held by a collection.
- Result makes success and recoverable failure part of the function's type.
