Question

我有这个查询，我认为我的条件是真的，但不知何故它给出了不正确的输出。

SELECT CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'd' THEN SecDebit END AS 'debit',
CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN SecCredit END AS 'credit',docdate,DATEDIFF(d,DocDate, GETDATE()) AS days,
CASE WHEN DATEDIFF(d,DocDate, GETDATE()) <= 365  THEN SecDebit ELSE 
CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE 0 END END AS 'secdebitlessthen365',
CASE WHEN DATEDIFF(d, DocDate, GETDATE()) > 365 AND DATEDIFF(d, DocDate, GETDATE()) <= 730  THEN SecDebit  ELSE 
CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE 0 END END AS 'secdebitgreaterthen365lessthenorequa730',
CASE WHEN DATEDIFF(d, DocDate, GETDATE()) > 730 AND DATEDIFF(d, DocDate, GETDATE()) <= 1095  THEN SecDebit ELSE 
CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE 0 END END AS 'secdebitgreaterthen730lessthenorequal1095',
CASE WHEN DATEDIFF(d, DocDate, GETDATE()) > 1095 THEN SecDebit ELSE 
CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE 0 END END AS 'secdebitgreaterthen1095'
FROM J_Transactions (NOLOCK) j
WHERE AccountID IN (871446)
AND j.DocTypeID=0

仅用于信用我的其他陈述是错误的

我的输出是

debit       credit      days    secdebit<365    secdebit>365<=730   secdebit>730<=1095  secdebit>1095   
24196.5000  NULL        783     0.0000         0.0000           24196.5000      0.0000    
NULL        24471.6500  418    -24471.6500     0.0000           -24471.6500     -24471.6500    
NULL        10.5800     418    -10.5800        0.0000           -10.5800        -10.5800

对于信用，这两天都是418，它应该在secdebit＆gt; 365＆lt; = 730之下，但它会进入除正确的那个之外的每个地方。有人能告诉我这个错误吗

期望的输出

debit       credit      days    secdebit<365    secdebit>365<=730   secdebit>730<=1095  secdebit>1095      
24196.5000  NULL        783     0.00           0.0000               24196.5000          0.00      
NULL        24471.6500  418     0.00          -24471.65             0.00                0.00   
NULL        10.5800     418     0.00          -10.5800              0.00                0.00

Answer 1

我不会重写你的整个查询，但我相信你想要修改你的case语句，以遵循更像这样的结构：

CASE WHEN DATEDIFF(d, DocDate, GETDATE()) <= 365 THEN 
    CASE WHEN CreditOrDebit = 'd' THEN SecDebit 
    ELSE -seccredit END
ELSE 0 END AS 'secdebitlessthan365'

Answer 2

无法理解您的业务逻辑。根据您提供的代码，问题是“Else”语句没有Days检查逻辑。我添加了相同的内容。请试一试。

{
"a":"1",
"b":"2"
}
{
"c":"3",
"d":"4"
}

在case case语句中，else部分输出不正确
