data for Update statements

Fields

begin_batch: Option<BeginBatch>

if present then statement starts with BEGIN BATCH

table_name: FQName

the table name to update

using_ttl: Option<TtlTimestamp>

if present then the TTL Timestamp for the update

assignments: Vec<AssignmentElement>

the column assignments for the update.

where_clause: Vec<RelationElement>

the where clause

if_clause: Vec<RelationElement>

if present a list of key,values for the IF clause

if_exists: bool

if true and if_clause is NONE then IF EXISTS is added to the statement

Trait Implementations

impl Clone for Update

fn clone(&self) -> Update

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Update

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

Formats the value using the given formatter.

impl Display for Update

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

Formats the value using the given formatter.

impl PartialEq for Update

fn eq(&self, other: &Update) -> 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.
