Question

How can I show a different value if some columns return FALSE,

for example,

COLUMN “BASIC” returns FALSE, but I need show for the user YES or NO. Case FALSE, return NO.

Answer 1

If varchar or bit, handling NULLs

case
    when BASIC = 'FALSE' then 'NO'
    when BASIC <> 'FALSE' then 'YES'
    else 'UNDEFINED'
end

or if just bit

case
    when BASIC = 1 then 'YES'
    when BASIC = 0 then 'NO'
    else 'UNDEFINED'
end

Edit:

SELECT 
    TipoImovel_Id AS TII_SEQ,
    Descricao AS TII_DSC, 
    Sigla AS TII_DSC_SIGLA,
    -- choose which one you want from the answers here
    case
        when BASIC = 1 then 'YES'
        when BASIC = 0 then 'NO'
        else 'UNDEFINED'
    end AS SomeColumnName
FROM San_TipoImovel";
