Question

MySQL

Hello!
How to rewrite code in MySQL procedure to MsSQL?

IF(SUM(Plan) < SUM(Fact), 0, SUM(Fact)/SUM(Plan)*100) as Equipment

Answer 1

IIF(SUM(Plan) < SUM(Fact), 0, SUM(Fact)/SUM(Plan)*100) as Equipment

Answer 2

case when SUM(Plan) < SUM(Fact) then 0 else SUM(Fact)/SUM(Plan)*100 end

I would just write the other way around.

case when SUM(Plan) >= SUM(Fact) then SUM(Fact)/SUM(Plan)*100 else 0 end
