Question

我遇到了一个小问题，希望得到任何帮助。

我的表是这样的：

var count = 0
// DOES NOTHING FOR 1 SEC
setTimeout(function () {
  var interval = setInterval(function () {

      $("#blinker").toggleClass(function(){
          count++
          return "blink"
      });

     // Reason it is 8 because it is counting the fadeIn and FadeOut  
     if (count == 8) 
         clearInterval(interval);

    }, 600)
}, 1000);

我的目标是CASH | CREDIT CARD | DEBIT CARD | ACCOUNT | OTHER ------------------------------------------------- 0.00 0.00 0.00 0.00 0.00 1.00 0.00 0.00 0.00 0.00 2.00 1.00 0.00 0.00 0.00上述任何有多列的行＆gt; 0

因此，在此场景中将使用上表选择第三行。

Answer 1

SELECT 
  [CASH], [CREDIT CARD], [DEBIT CARD], [ACCOUNT], [OTHER]
FROM table
WHERE
  CASE WHEN [CASH] > 0 THEN 1 ELSE 0 END+
  CASE WHEN [CREDIT CARD] > 0 THEN 1 ELSE 0 END+
  CASE WHEN [DEBIT CARD] > 0 THEN 1 ELSE 0 END+
  CASE WHEN [ACCOUNT] > 0 THEN 1 ELSE 0 END+
  CASE WHEN [OTHER] > 0 THEN 1 ELSE 0 END >= 2

Answer 2

我更喜欢t-clausen's answer但是作为练习，我决定将其作为UNPIVOT后跟PIVOT进行尝试，以便我们可以使用更多常规SQL工具编写它：

declare @t table (SomeID int,Cash money,Credit money,Debit money,Account money,Other money)
insert into @t(SomeID,Cash,Credit,Debit,Account,Other) values
(1,0.00,0.00,0.00,0.00,0.00),
(2,1.00,0.00,0.00,0.00,0.00),
(3,2.00,1.00,0.00,0.00,0.00)

;With Unpiv as (
    select *,SUM(CASE WHEN MoneyValue > 0.00 THEN 1 ELSE 0 END) OVER (PARTITION BY SomeID) as cnt
    from @t t
        unpivot (MoneyValue for MoneyType in (Cash,Credit,Debit,Account,Other)) x
), Repiv as (
    select *
    from Unpiv u
        pivot (SUM(MoneyValue) for MoneyType in (Cash,Credit,Debit,Account,Other)) x
    where
        cnt >= 2
)
select * from Repiv

这假设您有另一列（此处称为SomeID），通过该列可以唯一标识每一行。

结果：

SomeID      cnt         Cash                  Credit                Debit                 Account               Other
----------- ----------- --------------------- --------------------- --------------------- --------------------- ---------------------
3           2           2.00                  1.00                  0.00                  0.00                  0.00

希望上述内容可能更适合某些需求变体。

Answer 3

SELECT 
  [CASH], [CREDIT CARD], [DEBIT CARD], [ACCOUNT], [OTHER]
FROM table
WHERE (
  SELECT COUNT(*)
  FROM (VALUES ([CASH]),([CREDIT CARD]),([DEBIT CARD]),([ACCOUNT]),([OTHER])) t(value)
  WHERE value > 0
) >= 2

SQL查看表中的两个或多个列是否大于0
