無法獲得180天的SQL日期工作

Question

SELECT CTT.BAN, `Company`, `CID`, `FName`, `MInit`, 
    `LName`, `OName`, `Address`, `City`, `State`, 
    `PostalCode`, `ActiveDate`, `ClosedDate`, `Draft`, 
    `Credit`, `BillingCycle`, `BillingFreq`, `Suspended`, 
    `Paperless` , BTT.Bal 
FROM CustomerT CTT 
    JOIN BalanceT BTT 
ON (CTT.BAN = BTT.BAN) 
WHERE `Paperless` != '1' 
    AND `BankDraft` != -1 
    AND `CreditCard` != -1 
    AND (`BillingCycle` = '1' OR `BillingCycle` = '0') 
    AND `Bal` > 2 
    AND (`AccountClosedDate` IS NULL OR 
      DATE(`AccountClosedDate`) >= (NOW() - INTERVAL 180 DAY) ) 

一切與這個查詢，但180日期peice我已經嘗試了幾個東西從這個網站，沒有運氣。我只需要在表中包括最近6個月的閉帳額。

Answer 1

嘗試這與DATE_ADD

SELECT CTT.BAN, `Company`, `CID`, `FName`, `MInit`, `LName`, `OName`, `Address`, `City`, `State`, `PostalCode`, `ActiveDate`, `ClosedDate`, `Draft`, `Credit`, `BillingCycle`, `BillingFreq`, `Suspended`, `Paperless` , BTT.Bal 
FROM CustomerT CTT 
JOIN BalanceT BTT ON 
(CTT.BAN = BTT.BAN) 
WHERE `Paperless` != '1' 
AND `BankDraft` != -1 
AND `CreditCard` != -1 
AND (`BillingCycle` = '1' OR `BillingCycle` = '0') 
AND `Bal` > 2 
AND (`AccountClosedDate` IS NULL OR DATE(`AccountClosedDate`) >=DATE_ADD(CURDATE(), INTERVAL -180 DAY)) 

或使用(CURDATE() - INTERVAL 180 DAY)

SELECT CTT.BAN, `Company`, `CID`, `FName`, `MInit`, `LName`, `OName`, `Address`, `City`, `State`, `PostalCode`, `ActiveDate`, `ClosedDate`, `Draft`, `Credit`, `BillingCycle`, `BillingFreq`, `Suspended`, `Paperless` , BTT.Bal 
FROM CustomerT CTT 
JOIN BalanceT BTT ON 
(CTT.BAN = BTT.BAN) 
WHERE `Paperless` != '1' 
AND `BankDraft` != -1 
AND `CreditCard` != -1 
AND (`BillingCycle` = '1' OR `BillingCycle` = '0') 
AND `Bal` > 2 
AND (`AccountClosedDate` IS NULL OR DATE(`AccountClosedDate`) >=(CURDATE() - INTERVAL 180 DAY))
