pub struct UpdateBuilder { /* private fields */ }Expand description
Builder for update clauses
Implementations§
Source§impl UpdateBuilder
impl UpdateBuilder
Sourcepub fn predicate<E: Into<Expression>>(self, predicate: E) -> Self
pub fn predicate<E: Into<Expression>>(self, predicate: E) -> Self
Perform the update operation when the predicate is satisfied
Sourcepub fn update<C: Into<DeltaColumn>, E: Into<Expression>>(
self,
column: C,
expression: E,
) -> Self
pub fn update<C: Into<DeltaColumn>, E: Into<Expression>>( self, column: C, expression: E, ) -> Self
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
