Implementations

impl SelectBuilder

pub fn distinct(&mut self, value: Option<Distinct>) -> &mut SelectBuilder

pub fn top(&mut self, value: Option<Top>) -> &mut SelectBuilder

pub fn projection(&mut self, value: Vec<SelectItem>) -> &mut SelectBuilder

pub fn pop_projections(&mut self) -> Vec<SelectItem>

pub fn already_projected(&self) -> bool

pub fn into(&mut self, value: Option<SelectInto>) -> &mut SelectBuilder

pub fn from(&mut self, value: Vec<TableWithJoinsBuilder>) -> &mut SelectBuilder

pub fn push_from(&mut self, value: TableWithJoinsBuilder) -> &mut SelectBuilder

pub fn pop_from(&mut self) -> Option<TableWithJoinsBuilder>

pub fn lateral_views(&mut self, value: Vec<LateralView>) -> &mut SelectBuilder

pub fn replace_mark( &mut self, existing_expr: &Expr, value: &Expr, ) -> &mut SelectBuilder

Replaces the selection with a new value.

This function is used to replace a specific expression within the selection. Unlike the selection method which combines existing and new selections with AND, this method searches for and replaces occurrences of a specific expression.

This method is primarily used to modify LEFT MARK JOIN expressions. When processing a LEFT MARK JOIN, we need to replace the placeholder expression with the actual join condition in the selection clause.

Arguments

• existing_expr - The expression to replace
• value - The new expression to set as the selection

pub fn selection(&mut self, value: Option<Expr>) -> &mut SelectBuilder

pub fn cluster_by(&mut self, value: Vec<Expr>) -> &mut SelectBuilder

pub fn distribute_by(&mut self, value: Vec<Expr>) -> &mut SelectBuilder

pub fn sort_by(&mut self, value: Vec<OrderByExpr>) -> &mut SelectBuilder

pub fn having(&mut self, value: Option<Expr>) -> &mut SelectBuilder

pub fn named_window( &mut self, value: Vec<NamedWindowDefinition>, ) -> &mut SelectBuilder

pub fn qualify(&mut self, value: Option<Expr>) -> &mut SelectBuilder

pub fn value_table_mode( &mut self, value: Option<ValueTableMode>, ) -> &mut SelectBuilder

pub fn build(&self) -> Result<Select, BuilderError>
