Enum AggregateOp 

pub enum AggregateOp {
    Count,
    Sum(ColumnName),
    Avg(ColumnName),
    Min(ColumnName),
    Max(ColumnName),
    Ids {
        element_type: FlussoType,

}

Variants

Count

Sum(ColumnName)

Avg(ColumnName)

Min(ColumnName)

Max(ColumnName)

Ids

Collect the related table’s primary keys into a flat scalar array. The element type is stated explicitly (the schema names it) so the array’s mapping is known without touching the database.

Fields

element_type: FlussoType
