如何根據條件更新列

我有一個MySQL表，它看起來像這樣。如何根據條件更新列

+----------+-----------+----------+--------------+-------------+ 
| PONO  | ItemCode | OrderQty | ReflectedQty | OtherStatus | 
+----------+-----------+----------+--------------+-------------+ 
| PO787HZN | HKQSLUWKN | 30.00 | 30.00  | Posted  | 
| PO787HZN | SORHFRBPJ | 40.00 | 40.00  | Posted  | 
| PO787HZN | OP8XMREC0 | 50.00 | 50.00  | Posted  | 
| PO787HZN | CPD5CGDZ3 | 60.00 | 60.00  | Posted  | 
+----------+-----------+----------+--------------+-------------+

，並隨着時間的推移列ReflectedQty將被更新，它可能看起來像這樣

+----------+-----------+----------+--------------+-------------+ 
    | PONO  | ItemCode | OrderQty | ReflectedQty | OtherStatus | 
    +----------+-----------+----------+--------------+-------------+ 
    | PO787HZN | HKQSLUWKN | 30.00 | 20.00  | Posted  | 
    | PO787HZN | SORHFRBPJ | 40.00 | 1.00   | Posted  | 
    | PO787HZN | OP8XMREC0 | 50.00 | 5.00   | Posted  | 
    | PO787HZN | CPD5CGDZ3 | 60.00 | 6.00   | Posted  | 
    +----------+-----------+----------+--------------+-------------+

我的問題是如何能夠更新列OtherStatus到Partially Received或Fully Received如果列ReflectedQty = 0.00 ？

我怎樣才能實現這個使用選擇命令？

我將代碼解釋這個（樣品）

sqlcommand = select reflectedqty from table where reflectedqty = 0.00 and PONo = PO787HZN 

if all ReflectedQty of PO787HZN = 0.00 then 
'Update OtherStaus to = Fully Received 
else 
'Update OtherStaus to = Partially Received 
end if

任何其他代碼接受

查詢看起來像下面：

UPDATE your_table A 
SET A.ReflectedQty = A.ReflectedQty - @valueToBeDeducted, 
A.OtherStatus = 
       IF (
         (A.ReflectedQty - @valueToBeDeducted) <= 0, 
         'Fully Receieved', 
         'Partially Receieved' 
       ) 
WHERE...

_{是輸入參數}

如果你想在同一時間更新所有：

UPDATE your_table A 
SET A.OtherStatus = 
IF (
    A.ReflectedQty <= 0, 
    'Fully Receieved', 
    'Partially Receieved' 
) 
WHERE <your_condtion_here>

什麼valuetobededucted？ –

我猜想你通過這個作爲輸入，而從ReflectedQty中扣除。總之，它是一個輸入參數。順便說一下，你想一次更新所有的行嗎？然後看看第二個查詢 – 1000111

TYSM的幫助先生:)我做了一些更新與第二個代碼，因爲它爲我工作的一個。 TYSM –

您可以更新更新查詢本身檢查下面一個字段。

update yourtable set OtherStaus =(if(ReflectedQty='0.00' and PONO='PO787HZN','Fully Received','Partially Received'));

根據您的情況寫了sql語句。

TYSM求助：D –

SQL Server代碼：你需要做類似在MySQL

UPDATE Table T1 
SET 
OtherStatus = CASE 
       WHEN T2.RFQ = 0 THEN 'Fully Received' 
       ELSE 'Partially Received' 
       END 
FROM (
    SELECT PONO, SUM(ReflectedQty) RFQ GROUP BY PONO 
    ) T2 
INNER JOIN ON T2.PONO = T1.PONO
