Hi Guys need some help with converting this part of a query from MySQL, I need to run this on MSSQL.

Select (SUM(if(rating = 5, 1, 0))-SUM(if(RATING < 4, 1, 0)))/SUM(if(RATING > 0, 1, 0))*100 as RECENT_NPS,
SUM(if(RATING > 0, 1, 0)) as RECENT_RATINGS,

Hi

Try replacing your IF functions with a CASE statements, eg

if(rating = 5, 1, 0)

becomes

CASE WHEN rating = 5 THEN 1 ELSE 0 END

In SQL 2012 there is also the IIF function that could be used
