pub fn delete<T: IntoUpdateTarget>(
source: T
) -> DeleteStatement<T::Table, T::WhereClause>Expand description
Creates a DELETE statement.
When a table is passed to delete,
every row in the table will be deleted.
This scope can be narrowed by calling filter
on the table before it is passed in.
Examples
Deleting a single record:
let old_count = get_count();
diesel::delete(users.filter(id.eq(1))).execute(&connection)?;
assert_eq!(old_count.map(|count| count - 1), get_count());Deleting a whole table:
diesel::delete(users).execute(&connection)?;
assert_eq!(Ok(0), get_count());
