Add filter in stored procedure but give error invalid

Question

When I add filter in my stored procedure, it throws an error "invalid column name".

My query is:

select name, monthlysalary as ms 
from Patient 
where ms = 2000;

Answer 1

You can not use aliases at where part

It should be like that.

select name, monthlysalary as ms from Patient where monthlysalary =2000;
