SQL查詢添加一列，即案例後的行總和

Question

如果下面的代碼冒犯任何人作爲專業人員，讓我事先道歉，現在的問題： 下面的一切完成後，它吐出了我究竟是什麼在尋找，如果該列有一個字符串，我得到1，如果不是零。我的意圖是添加第7列，添加這些列，以便我可以將它彙集到報告中的公式中，並將其與另一列進行比較。我確信有可能在查詢中做，我只是不知道如何。 Server是SQL 2008

select CASE 
WHEN [1 First Name] = '' 
THEN 1 
ELSE 0 
    END as "First Name 1", 
    CASE 
WHEN [1 Last Name] = '' 
THEN 1 
ELSE 0 
    END as "Last Name 1", 
    CASE 
WHEN [2 First Name] = '' 
THEN 1 
ELSE 0 
    END as "First name 2", 
    CASE 
WHEN [2 Last Name] = '' 
THEN 1 
ELSE 0 
    END as "Last Name 2", 
    CASE 
WHEN [3 First Name] = '' 
THEN 1 
ELSE 0 
    END as "First Name 3", 
    CASE 
WHEN [3 Last Name] = '' 
THEN 1 
ELSE 0 
    END as "Last Name 3" 
    FROM 
    member

這將總結你的1秒對所有的行和列

    "First Name 1"+ 
     "Last Name 1"+ 
     "First name 2"+ 
     "Last Name 2"+ 
     "First Name 3"+ 
     "Last Name 3" AS TheSum 
FROM

     CASE WHEN [1 Last Name] = '' THEN 1 ELSE 0 END as "Last Name 1", 
     CASE WHEN [2 First Name] = '' THEN 1 ELSE 0 END as "First name 2", 
     CASE WHEN [2 Last Name] = '' THEN 1 ELSE 0 END as "Last Name 2", 
     CASE WHEN [3 First Name] = '' THEN 1 ELSE 0 END as "First Name 3",

除非我失去了一些東西你可以把你的當前查詢的子查詢，然後添加一個列有總數：

select "First Name 1", 
    "Last Name 1", 
    "First name 2", 
    "Last Name 2", 
    "First Name 3", 
    "Last Name 3", 
    ("First Name 1" +"Last Name 1"+"First name 2"+"Last Name 2"+"First Name 3"+"Last Name 3") As total 
from 
(
    select CASE 
      WHEN [1 First Name] = '' THEN 1 ELSE 0 
     END as "First Name 1", 
     CASE 
      WHEN [1 Last Name] = '' THEN 1 ELSE 0 
     END as "Last Name 1", 
     CASE 
      WHEN [2 First Name] = '' THEN 1 ELSE 0 
     END as "First name 2", 
     CASE 
      WHEN [2 Last Name] = '' THEN 1 ELSE 0 
     END as "Last Name 2", 
     CASE 
      WHEN [3 First Name] = '' THEN 1 ELSE 0 
     END as "First Name 3", 
     CASE 
      WHEN [3 Last Name] = '' THEN 1 ELSE 0 
     END as "Last Name 3" 
    FROM member 
) m
