Question

I have a table where each entry can have sequence number of 1 or 2. I want to choose one of these options based on the value of the current year. Is it possible to do the following in a where statement:

(CASE sequence_number 
    WHEN cy.curyr < '41' THEN '1' 
    ELSE '2' 
       END ) sequence_number

Answer 1

the correct way in a where clause would be

and sequence_number = case when cy.curyr < '41' then 1 else 2 end

is curyr a string though?
