pub struct UpdateBuilder { /* private fields */ }

Expand description

Builder for update clauses

Implementations§

source §

impl UpdateBuilder

source

pub fn predicate<E>(self, predicate: E) -> UpdateBuilder
where E: Into<Expression>,

Perform the update operation when the predicate is satisfied

source

pub fn update<C, E>(self, column: C, expression: E) -> UpdateBuilder
where C: Into<DeltaColumn>, E: Into<Expression>,

How a column from the target table should be updated. In the match case the expression may contain both source and target columns. In the source not match case the expression may only contain target columns
