Enum MergeAction 

pub enum MergeAction {
    Insert {
        columns: Vec<String>,
        values: Vec<Expr>,
    },
    Update {
        assignments: Vec<(String, Expr)>,
    },
    Delete,
    DoNothing,
}

Variants

Insert

INSERT (cols) VALUES (vals). SPG v7.17 requires the explicit column list (the bare INSERT VALUES (vals) shape lands later).

Fields

columns: Vec<String>

values: Vec<Expr>

Update

UPDATE SET col = expr [, …] — applied to every matched target row for the firing source row.

Fields

assignments: Vec<(String, Expr)>

Delete

DELETE — drop every matched target row.

DoNothing

DO NOTHING — explicit no-op (the SQL standard accepts the clause and SPG mirrors so a customer-side MERGE that uses it for branch-control doesn’t error).

Trait Implementations

impl Clone for MergeAction

fn clone(&self) -> MergeAction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MergeAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MergeAction

fn eq(&self, other: &MergeAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
