MySQL服務器版本正確的語法近ID使用

Question

MySQL數據庫查詢：

SELECT * 
FROM (SELECT * 
     FROM (`static_package_data`) 
      LEFT JOIN package_interest pi ON static_package_data.id=pi.package_details_id 
     WHERE `package_availability_type` = 'all' 
      AND `admin_status` = 'ACTIVE' 
      AND `status` = 'ACTIVE' 
      AND static_package_data.package_price BETWEEN 2000 AND 5000 
      AND WHERE 'static_package_data.session_id'='AE44278818' 
     GROUP BY static_package_data.id 
     UNION ALL 
     SELECT * 
     FROM (`static_package_data`) 
      LEFT JOIN package_interest pi ON static_package_data.id=pi.package_details_id 
     WHERE `package_availability_type` ='range' 
      AND `admin_status` = 'ACTIVE' 
      AND `status` = 'ACTIVE' 
      AND `to_date` >= '2017-02-04'AND static_package_data.package_price BETWEEN 2000 AND 5000 
      AND WHERE 'static_package_data.session_id'='AE44278818' 
     GROUP BY static_package_data.id 
    ) as dt LIMIT 0 , 10 

下面的查詢拋出了一個錯誤：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near WHERE 'static_package_data.session_id'='AE44278818' GROUP BY static_package_data.' at line 1

我說會話ID從我現有的查詢

Answer 1

簡單，

SELECT * 
FROM ( 
       SELECT * 
       FROM  (`static_package_data`) 
       LEFT JOIN package_interest pi 
       ON  static_package_data.id=pi.package_details_id 
       WHERE  `package_availability_type` = 'all' 
       AND  `admin_status` = 'ACTIVE' 
       AND  `status` = 'ACTIVE' 
       AND  static_package_data.package_price BETWEEN 2000 AND  5000 
       AND 
       WHERE  'static_package_data.session_id'='AE44278818' 
       GROUP BY static_package_data.id 
       UNION ALL 
       SELECT * 
       FROM  (`static_package_data`) 
       LEFT JOIN package_interest pi 
       ON  static_package_data.id=pi.package_details_id 
       WHERE  `package_availability_type` ='range' 
       AND  `admin_status` = 'ACTIVE' 
       AND  `status` = 'ACTIVE' 
       AND  `to_date` >= '2017-02-04' 
       AND  static_package_data.package_price BETWEEN 2000 AND  5000 
       AND 
       WHERE  'static_package_data.session_id'='AE44278818' 
       GROUP BY static_package_data.id) AS dt limit 0 , 
     10; 

Answer 2

你只需要一個「WHERE」之後的任何東西就應該是AND

2000 AND 5000 AND WHERE 'static_package_data.session_id'='AE4 

應該

2000 AND 5000 AND 'static_package_data.session_id'='AE4 

Answer 3

有兩個額外的WHERE條款在你的代碼與其他的語法錯誤，如各地的列名，而不是反引號單引號一起。

SELECT 
    * 
FROM 
    (SELECT 
     * 
    FROM 
     `static_package_data` 
    LEFT JOIN package_interest pi ON static_package_data.id = pi.package_details_id 
    WHERE 
     `package_availability_type` = 'all' 
      AND `admin_status` = 'ACTIVE' 
      AND `status` = 'ACTIVE' 
      AND `static_package_data`.package_price BETWEEN 2000 AND 5000 
      AND `static_package_data`.`session_id` = 'AE44278818' 
    GROUP BY static_package_data.id UNION ALL SELECT 
     * 
    FROM 
     `static_package_data` 
    LEFT JOIN package_interest pi ON static_package_data.id = pi.package_details_id 
    WHERE 
     `package_availability_type` = 'range' 
      AND `admin_status` = 'ACTIVE' 
      AND `status` = 'ACTIVE' 
      AND `to_date` >= '2017-02-04' 
      AND `static_package_data`.package_price BETWEEN 2000 AND 5000 
      AND `static_package_data`.`session_id` = 'AE44278818' 
    GROUP BY `static_package_data`.id) AS dt 
-- Consider adding an order by clause here -- 
LIMIT 0 , 10 

而且，考慮使用限制或任何其他行10將獲取時添加order by子句來查詢。
