insert and update in single statement

Question

INSERT INTO table (a,b,c) VALUES (1,2,3) ON DUPLICATE KEY UPDATE a='4', b='5', c='6'

如果可能，如何在单个语句中的Rails中实现这种类型的SQL（插入和更新）

Answer 1

You can run your sql directly:

sql = "INSERT INTO table (a,b,c) VALUES (1,2,3) ON DUPLICATE KEY UPDATE a='4', b='5', c='6'"
ActiveRecord::Base.connection.insert_sql sql
