Trait diesel::prelude::EscapeExpressionMethods
source · pub trait EscapeExpressionMethods: Sized {
// Required method
fn escape(self, _character: char) -> Escape<Self>;
}
Expand description
Adds the escape
method to LIKE
and NOT LIKE
. This is used to specify
the escape character for the pattern.
By default, the escape character is \
on most backends. On SQLite,
there is no default escape character.
§Example
let users_with_percent = users.select(name)
.filter(name.like("%😀%%").escape('😀'))
.load(connection);
let users_without_percent = users.select(name)
.filter(name.not_like("%a%%").escape('a'))
.load(connection);
assert_eq!(Ok(vec![String::from("Ha%%0r")]), users_with_percent);
assert_eq!(Ok(vec![String::from("Sean"), String::from("Tess")]), users_without_percent);
