Enum AggregateFunction 

pub enum AggregateFunction {
    Count,
    Sum,
    Total,
    Avg,
    Min,
    Max,
    GroupConcat {
        separator: Option<String>,

}

Supported aggregate function types.

Variants

Count

Sum

Max

GroupConcat

Fields

separator: Option<String>

StringAgg

Fields

separator: Option<String>

PercentileDisc

Ordered-set aggregate PERCENTILE_DISC(fraction) WITHIN GROUP (ORDER BY ...) (issue #148). fraction is validated by the planner to be a literal in [0, 1]. Issue #154 (PERCENTILE_CONT / MODE) extends this enum with sibling variants reusing the same ordered-input path.

Fields

fraction: f64
