Question

I need to update date a value in table if it does not exist then it must be inserted

What is the best way to does this in MySql

Currently I am using

   SELECT Id INTO LId  FROM ATABLE WHERE ID = FID;
   IF LId IS NULL THEN
     INSERT INTO ATABLE(abc) Values (2)
   ELSE
     UPDATE ATABLE Set Abc = 2 Where Id = LId
   END IF;

But this hits the Database 3 times

Is there a better way of doing this ?

Answer 1

INSERT ... ON DUPLICATE KEY UPDATE

That’s what you’re looking for 🙂
