Question

I’ve simple example to describe my problem. Lets say I’ve table structured like this =>

create table A(
id INT(3) NOT NULL AUTO_INCREMENT PRIMARY_KEY,
act DATETIME,
act_reset INT(1) DEFAULT 0);

I want to write query with condition that if act_reset is true (so if not 0) then update column act DATETIME.

I’ve tried it like this=>

IF act_reset THEN UPDATE A SET act=now() WHERE id=1 END IF;

but this syntax is not valid, how I must write this condition with one query ? thanks

Answer 1

UPDATE A SET act=now() WHERE id=1 AND act_reset <> 0

Is this the query you are looking for?

Using If statement in MySQL :

IF act_reset <> 0 THEN 
  UPDATE A SET act=now() WHERE id=1 
END IF;
