Hello, 

 

I have var A and Var B and using those two I would like to create a combine variable using the value for either A or B depending on the survey year. 

 

So, if survey year=5 then combine variable= values in variable A

       if survey year 6 then combine variable= values in variable B

 

Thanks for your help in advance!

When you say combine, do you mean concatenate? Are the current values text or numeric?

To do this in a SQL query, use a case expression:

 

case when survey_year=5 then mean(A) else mean(B) end as yearMean
