错误的语句

select
            (
              case
                  when money > 0 then
                    CONCAT(\'收入\',abs(format(money, 2)),\'元\')
                  else
                    CONCAT(\'支持\',abs(format(money, 2)),\'元\')
              end
            ) as moneyLabel,
            b.*
         from api_billing b where 1=1
       
            and user_id = 1

正确的写法：

select
        (
            case
                    when money > 0 then
                        CONCAT(\'收入\',abs(truncate(money, 2)),\'元\')
                    else
                        CONCAT(\'支持\',abs(truncate(money, 2)),\'元\')
            end
        ) as moneyLabel,
        b.*
 from api_billing b where 1=1

        and user_id = 1

order by id desc
