Question

我有一个复杂的更新，我想在重复键更新时更改为插入。插入忽略工作，更新工作;但是当我结合时，我得到了错误：

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 'INNER JOIN at_award_description ON at_cub_award_date.ad_id = at_award_descriptio' at line 1

原始的INSERT是：

String insertQry = ("INSERT IGNORE INTO at_cub_award_date (ca_id, ad_id, cad_status_flag) " +
                        "VALUES (?, (SELECT ad_id " + 
                        "FROM at_award_description " + 
                        "WHERE at_award_description.aw_id = ? " +
                            "AND at_award_description.ad_group = ? " +
                            "AND at_award_description.ad_order = '1'), ?);");

原始更新是：

String updateQry = ("UPDATE at_cub_award_date dest " +
            "INNER JOIN at_award_description " +
            "ON dest.ad_id = at_award_description.ad_id " +
                    "AND at_award_description.aw_id = ? " +
                    "AND at_award_description.ad_group = ? " +
                    "AND at_award_description.ad_order = '1' " +
            "SET dest.cad_status_flag = 'S' " +
            "WHERE dest.ca_id = ? " +
                //No Group Completion date
                "AND (SELECT noCompletedGroup FROM " +
                    "(SELECT COUNT(*) noCompletedGroup " +
                        "FROM at_cub_award_date, at_award_description " +
                        "WHERE at_award_description.aw_id = ? " +
                            "AND at_award_description.ad_group = ? " +
                            "AND at_award_description.ad_detail LIKE '%Completed:%' " +
                            "AND at_award_description.ad_id = at_cub_award_date.ad_id " +
                            "AND at_cub_award_date.ca_id = ? " +
                            "AND at_cub_award_date.cad_task_completion_date IS NOT NULL) AS T1) = 0 " +
                //A task in the Group has completed
                "AND (SELECT noCompletedTasks FROM " +
                    "(SELECT COUNT(*) noCompletedTasks " +
                        "FROM at_cub_award_date, at_award_description " +
                        "WHERE at_award_description.aw_id = ? " +
                            "AND at_award_description.ad_group = ? " +
                            "AND at_award_description.ad_id = at_cub_award_date.ad_id " +
                            "AND at_cub_award_date.ca_id = ? " +
                            "AND at_cub_award_date.cad_task_completion_date IS NOT NULL) AS T2) > 0;");

重复密钥更新的新INSERT是：

String insertQry = ("INSERT INTO at_cub_award_date (ca_id, ad_id, cad_status_flag) " +
                            "VALUES (?, (SELECT ad_id " + 
                            "FROM at_award_description " + 
                            "WHERE at_award_description.aw_id = ? " +
                                "AND at_award_description.ad_group = ? " +
                                "AND at_award_description.ad_order = '1'), ?) " +
            "ON DUPLICATE KEY UPDATE at_cub_award_date " +
            "INNER JOIN at_award_description " +
            "ON at_cub_award_date.ad_id = at_award_description.ad_id " +
                    "AND at_award_description.aw_id = ? " +
                    "AND at_award_description.ad_group = ? " +
                    "AND at_award_description.ad_order = '1' " +
            "SET at_cub_award_date.cad_status_flag = 'S' " +
            "WHERE at_cub_award_date.ca_id = ? " +
                //No Group Completion date
                "AND (SELECT noCompletedGroup FROM " +
                    "(SELECT COUNT(*) noCompletedGroup " +
                        "FROM at_cub_award_date, at_award_description " +
                        "WHERE at_award_description.aw_id = ? " +
                            "AND at_award_description.ad_group = ? " +
                            "AND at_award_description.ad_detail LIKE '%Completed:%' " +
                            "AND at_award_description.ad_id = at_cub_award_date.ad_id " +
                            "AND at_cub_award_date.ca_id = ? " +
                            "AND at_cub_award_date.cad_task_completion_date IS NOT NULL) AS T1) = 0 " +
                //A task in the Group has completed
                "AND (SELECT noCompletedTasks FROM " +
                    "(SELECT COUNT(*) noCompletedTasks " +
                        "FROM at_cub_award_date, at_award_description " +
                        "WHERE at_award_description.aw_id = ? " +
                            "AND at_award_description.ad_group = ? " +
                            "AND at_award_description.ad_id = at_cub_award_date.ad_id " +
                            "AND at_cub_award_date.ca_id = ? " +
                            "AND at_cub_award_date.cad_task_completion_date IS NOT NULL) AS T2) > 0;");

将两者分开是否有任何问题？我读到第二个陈述可能在第一个陈述之前开始并产生虚假结果。

有更好的方法吗？

MySQL结合了INSERT和复杂的UPDATE准备语句
