sql stored procedure + if statement

is it possible to have an if statement in a query - so if a value of a variable is 'yes' for example a line is added to the query ?



select * from table
where date >= getDate()
if @Variable = 'yes' then add this line of code to the query
and customerActive = 1

If @variable could ever possibly be null rather than no:

select * from table
where date >= getDate() and (@variable is null or @variable = 'n' or customerActive = 1)
