如果是varchar或bit，则处理NULL
case
when BASIC = 'FALSE' then 'NO'
when BASIC <> 'FALSE' then 'YES'
else 'UNDEFINED'
end
或者如果只是一点点
case
when BASIC = 1 then 'YES'
when BASIC = 0 then 'NO'
else 'UNDEFINED'
end

SELECT
TipoImovel_Id AS TII_SEQ,

-- choose which one you want from the answers here
case
when BASIC = 1 then 'YES'
when BASIC = 0 then 'NO'
