Struct tidb_query_aggr::impl_max_min::AggFnStateExtremumForSet[−][src]

pub struct AggFnStateExtremumForSet<E> where
    E: Extremum,
    VectorValue: VectorValueExt<Set>,  {
    extremum: Option<Set>,
    _phantom: PhantomData<E>,
}

Fields

extremum: Option<Set>_phantom: PhantomData<E>

Implementations

`impl<E> AggFnStateExtremumForSet<E> where E: Extremum, VectorValue: VectorValueExt<Set>,` [src]

`pub fn new() -> Self`[src]

`fn update_concrete( &mut self, _ctx: &mut EvalContext, value: Option<SetRef<'_>> ) -> Result<()>`[src]

Notes

For MAX(), MySQL currently compares ENUM and SET columns by their string value rather than by the string’s relative position in the set. This differs from how ORDER BY compares them.
