Filter expression used in query.filter method.

Implementations§

source§

impl<'b> FilterExpr<'b>

source

pub fn or(self, rhs: FilterExpr<'b>) -> Self

supplement ‘or’ filters for current filter statement.

let query = Person::query().filter(
    Person::col("id")?.is_in_ref(&[&3, &"4", &5])
            .or(Person::col("id")?.gt(&20))
)?
 .filter(
    Person::col("email")?.contains("gmail")
)?;

SQL: ... WHERE (person.id IN (3,'4',5) OR person.id > 20) AND person.email LIKE '%gmail%'
