Compiled Select Expression.

Fields (Non-exhaustive)

This struct is marked as non-exhaustive

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

colnames: Vec<String>

assigns: Assigns

exps: Vec<CExpPtr<Value>>

from: Option<CTableExpression>

wher: Option<CExpPtr<bool>>

orderby: Vec<CExpPtr<Value>>

desc: Vec<bool>
