Question

How do I perform an IF...THEN in an SQL SELECT statement?

For example:

SELECT IF(Obsolete = \'N\' OR InStock = \'Y\' ? 1 :          


        

Answer 1

Microsoft SQL Server (T-SQL)

In a select, use:

select case when Obsolete = 'N' or InStock = 'Y' then 'YES' else 'NO' end

In a where clause, use:

where 1 = case when Obsolete = 'N' or InStock = 'Y' then 1 else 0 end
