Enum OnConflictAction 

pub enum OnConflictAction {
    Nothing,
    Update {
        assignments: Vec<(String, Expr)>,
        where_: Option<Expr>,
    },
}

Variants

Update

DO UPDATE SET col = expr [, …] [WHERE cond]. assignments may reference EXCLUDED.col to read the incoming row’s value (engine wires EXCLUDED as a virtual table).

Fields

assignments: Vec<(String, Expr)>

where_: Option<Expr>
