Struct quaint::ast::Delete

pub struct Delete<'a> { /* fields omitted */ }

A builder for a DELETE statement.

Methods

impl<'a> Delete<'a>

pub fn from_table<T>(table: T) -> Self where
    T: Into<Table<'a>>, 

Creates a new DELETE statement for the given table.

let query = Delete::from_table("users");
let (sql, _) = Sqlite::build(query);

assert_eq!("DELETE FROM `users`", sql);

pub fn so_that<T>(self, conditions: T) -> Self where
    T: Into<ConditionTree<'a>>, 

Adds WHERE conditions to the query. See Comparable for more examples.

let query = Delete::from_table("users").so_that("bar".equals(false));
let (sql, params) = Sqlite::build(query);

assert_eq!("DELETE FROM `users` WHERE `bar` = ?", sql);
assert_eq!(vec![ParameterizedValue::Boolean(false)], params);
