對日期時間字段運行選擇查詢時出錯

Question

我收到此錯誤：

1064-您的SQL語法有誤； 在第1行上，檢查與您的MySQL服務器版本相對應的手冊，以在'=>“ 2018-08-14” AND createDate = <“ 2018-08-28” ORDER BY createDate DESC LIMIT 0，'附近使用正確的語法

當我運行此查詢時：

SELECT * FROM offer_request WHERE createDate => "2018-08-14" AND createDate =< "2018-08-28" ORDER BY createDate DESC LIMIT 0, 15

createDate是日期時間字段。 即：2018-07-19 12:53:59

Answer 1

使用日期函數轉換createDate：

SELECT * FROM offer_request WHERE date(createDate) >= '2018-08-14' AND date(createDate) <= '2018-08-28' ORDER BY createDate DESC LIMIT 0, 15

Answer 2

您的SQL查詢中有錯誤，必須像這樣使用，並嘗試對datetime字段使用date（）函數

SELECT * FROM offer_request WHERE date(createDate) >= '2018-08-14' AND date(createDate) =< '2018-08-28' ORDER BY createDate DESC LIMIT 0, 15

Answer 3

嘗試這種最簡單有效的方法:)

  SELECT * FROM offer_request WHERE createDate BETWEEN "2018-08-14" AND "2018-08-28" ORDER BY createDate DESC LIMIT 0, 15
