Struct Having 

pub struct Having {
    pub conditions: Vec<Expr>,
}

HAVING a AND b

Structurally identical to Where and deliberately a separate type: a statement has at most one of each, and a having mod must not be accepted where only a WHERE exists.

Fields

conditions: Vec<Expr>

The conditions, in the order they were appended.
