An interface to get a tuple value from the query result

Required Methods

fn try_get_many( res: &QueryResult, pre: &str, cols: &[String] ) -> Result<Self, TryGetError>

Get a tuple value from the query result with prefixed column name

fn try_get_many_by_index(res: &QueryResult) -> Result<Self, TryGetError>

Get a tuple value from the query result based on the order in the select expressions

Provided Methods

fn find_by_statement<C>( stmt: Statement ) -> SelectorRaw<SelectGetableValue<Self, C>>

where C: IntoEnumIterator + Iden,

use sea_orm::{entity::*, query::*, tests_cfg::cake, DeriveIden, EnumIter, TryGetableMany};
