Std.Db.Query.Shape.select

1 declaration

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.
