聯合凡在MySQL查詢

我有一個查詢，我使用UNION從兩個表中獲取數據子句UNION SELECT，它顯示正確，但問題是當我需要選擇不同的日期間隔在此期間進行顯示的數據，有什麼恰巧它只需要一個where子句並將其應用於該單個SELECT部分而不是整個查詢。我需要這個來應用於wholle ......怎麼樣？聯合凡在MySQL查詢

SELECT 
    TICKETS.TICKETID AS TICKET_NO, 
    RECEIPTS.DATENEW AS DATENEW, 
    PAYMENTS.TOTAL AS MONEY, 
    CUSTOMERS.NAME AS CUSTOMER, 
    PAYMENTS.PAYMENT AS PAYMENT 
FROM RECEIPTS 
    LEFT JOIN TICKETS ON RECEIPTS.ID = TICKETS.ID 
    LEFT JOIN PAYMENTS ON RECEIPTS.ID = PAYMENTS.RECEIPT 
    LEFT JOIN CUSTOMERS ON TICKETS.CUSTOMER = CUSTOMERS.ID 
WHERE ?(QBF_FILTER) 
UNION SELECT 
    ADJUSTMENTS.TICKET_NO AS TICKET_NO, 
    ADJUSTMENTS.DATE AS DATENEW, 
    ADJUSTMENTS.ADJUSTMENT_AMOUNT AS MONEY, 
    ADJUSTMENTS.CUSTOMER_NAME AS CUSTOMER, 
    ADJUSTMENTS.ADJUSTMENT_TYPE AS PAYMENT 
FROM ADJUSTMENTS 
    LEFT JOIN CUSTOMERS ON CUSTOMERS.ID = ADJUSTMENTS.CUSTOMER_ID 
    WHERE ?(QBF_FILTER)

>>>>上面的查詢從UNICENTA開放源代碼項目，它使用文件.BS生成報告，當我把拍攝地點在兩個選擇部分條款會生成SQL語法錯誤，現在我上面討論的問題是我需要解決的，謝謝：|

您可以用嵌套選擇實現這一點：

SELECT * FROM (
    SELECT 
     TICKETS.TICKETID AS TICKET_NO, 
     RECEIPTS.DATENEW AS DATENEW, 
     PAYMENTS.TOTAL AS MONEY, 
     CUSTOMERS.NAME AS CUSTOMER, 
     PAYMENTS.PAYMENT AS PAYMENT 
    FROM RECEIPTS 
     LEFT JOIN TICKETS ON RECEIPTS.ID = TICKETS.ID 
     LEFT JOIN PAYMENTS ON RECEIPTS.ID = PAYMENTS.RECEIPT 
     LEFT JOIN CUSTOMERS ON TICKETS.CUSTOMER = CUSTOMERS.ID 
    WHERE ?(QBF_FILTER) 
    UNION SELECT 
     ADJUSTMENTS.TICKET_NO AS TICKET_NO, 
     ADJUSTMENTS.DATE AS DATENEW, 
     ADJUSTMENTS.ADJUSTMENT_AMOUNT AS MONEY, 
     ADJUSTMENTS.CUSTOMER_NAME AS CUSTOMER, 
     ADJUSTMENTS.ADJUSTMENT_TYPE AS PAYMENT 
    FROM ADJUSTMENTS 
     LEFT JOIN CUSTOMERS ON CUSTOMERS.ID = ADJUSTMENTS.CUSTOMER_ID 
     WHERE ?(QBF_FILTER) 
    ) 
WHERE (yourDate between Date1 and Date2)

編輯：我想這需要更多這樣的：

SELECT * FROM (
    SELECT 
     TICKETS.TICKETID AS TICKET_NO_REC, 
     RECEIPTS.DATENEW AS DATENEW_REC, 
     PAYMENTS.TOTAL AS MONEY_REC, 
     CUSTOMERS.NAME AS CUSTOMER_REC, 
     PAYMENTS.PAYMENT AS PAYMENT_REC 
    FROM RECEIPTS 
     LEFT JOIN TICKETS ON RECEIPTS.ID = TICKETS.ID 
     LEFT JOIN PAYMENTS ON RECEIPTS.ID = PAYMENTS.RECEIPT 
     LEFT JOIN CUSTOMERS ON TICKETS.CUSTOMER = CUSTOMERS.ID 
    UNION SELECT 
     ADJUSTMENTS.TICKET_NO AS TICKET_NO_ADJ, 
     ADJUSTMENTS.DATE AS DATENEW_ADJ, 
     ADJUSTMENTS.ADJUSTMENT_AMOUNT AS MONEY_ADJ, 
     ADJUSTMENTS.CUSTOMER_NAME AS CUSTOMER_ADJ, 
     ADJUSTMENTS.ADJUSTMENT_TYPE AS PAYMENT_ADJ 
    FROM ADJUSTMENTS 
     LEFT JOIN CUSTOMERS ON CUSTOMERS.ID = ADJUSTMENTS.CUSTOMER_ID 
    ) 
WHERE ?(QBF_FILTER)

此嵌套select語句仍然會產生相同的SQL語法錯誤，那就是我想要預防的！ – Saqib

奇怪，我不知道什麼是你的WHERE子句傳遞的子選擇。你可以把這兩個看出來，看看它給你什麼？ – StaticVoid

需要日期是DATENEW在這兩個選擇，如果我拿出兩個WHERE子句它給附近UNION SELECT SQL語法錯誤.. :( – Saqib
