A builder for SelectColumn.

Implementations§

source§

impl SelectColumnBuilder

source

pub fn name(self, input: impl Into<String>) -> Self

Name of the column.

source

pub fn set_name(self, input: Option<String>) -> Self

Name of the column.

source

pub fn get_name(&self) -> &Option<String>

Name of the column.

source

pub fn type(self, input: Type) -> Self

Contains the data type of a column in a query result set. The data type can be scalar or complex. The supported scalar data types are integers, Boolean, string, double, timestamp, date, time, and intervals. The supported complex data types are arrays, rows, and timeseries.

source

pub fn set_type(self, input: Option<Type>) -> Self

Contains the data type of a column in a query result set. The data type can be scalar or complex. The supported scalar data types are integers, Boolean, string, double, timestamp, date, time, and intervals. The supported complex data types are arrays, rows, and timeseries.

source

pub fn get_type(&self) -> &Option<Type>

Contains the data type of a column in a query result set. The data type can be scalar or complex. The supported scalar data types are integers, Boolean, string, double, timestamp, date, time, and intervals. The supported complex data types are arrays, rows, and timeseries.

source

pub fn database_name(self, input: impl Into<String>) -> Self

Database that has this column.

source

pub fn set_database_name(self, input: Option<String>) -> Self

Database that has this column.

source

pub fn get_database_name(&self) -> &Option<String>

Database that has this column.

source

pub fn table_name(self, input: impl Into<String>) -> Self

Table within the database that has this column.

source

pub fn set_table_name(self, input: Option<String>) -> Self

Table within the database that has this column.

source

pub fn get_table_name(&self) -> &Option<String>

Table within the database that has this column.

source

pub fn aliased(self, input: bool) -> Self

True, if the column name was aliased by the query. False otherwise.

source

pub fn set_aliased(self, input: Option<bool>) -> Self

True, if the column name was aliased by the query. False otherwise.

source

pub fn get_aliased(&self) -> &Option<bool>

True, if the column name was aliased by the query. False otherwise.

source

pub fn build(self) -> SelectColumn

Consumes the builder and constructs a SelectColumn.

impl PartialEq<SelectColumnBuilder> for SelectColumnBuilder

source§

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