Function diesel::dsl::replace_into [−][src]
pub fn replace_into<T>(target: T) -> IncompleteInsertStatement<T, Replace>
Expand description
Creates a REPLACE
statement.
If a constraint violation fails, the database will attempt to replace the offending row instead. This function is only available with MySQL and SQLite.
Example
replace_into(users) .values(&vec![ (id.eq(1), name.eq("Sean")), (id.eq(2), name.eq("Tess")), ]) .execute(&conn) .unwrap(); replace_into(users) .values((id.eq(1), name.eq("Jim"))) .execute(&conn) .unwrap(); let names = users.select(name).order(id).load::<String>(&conn); assert_eq!(Ok(vec!["Jim".into(), "Tess".into()]), names);
