带有子查询和额外列的插入语句

Question

我想将插入语句与来自另一个 table 的 select 子查询一起使用。就我而言，我想添加从 PRESENTATION table 到 AVAILABILITY table 的一行。

AVAILABILITY table 结构：

availableID        (number, generated using sequence)
availableDay       (varchar)
availableStart     (varchar)
availableEnd       (varchar)
lecturerID(FK)     (varchar)
presentationID(FK) (number, generated using sequence)

PRESENTATION table 结构：

presentationID         (number, generated using sequence)
presentationDay        (varchar)
presentationStart      (varchar)
presentationEnd        (varchar)

我试着在 DAO 中构建查询，如下所示：

        String lecturerID = Abean.getLecturerID();
        String availableDay = Abean.getAvailableDay();
        String availableStart = Abean.getAvailableStart();
        String availableEnd = Abean.getAvailableEnd();
        Date availableDate = Abean.getAvailableDate();
        String presentationID = Abean.getPresentationID();

    try{  

            currentCon = JavaConnectionDB.getConnection();

            PreparedStatement ps=currentCon.prepareStatement("
            insert into availability (availableID,
                                      lecturerID,
                                      availableDay,
                                      availableStart,
                                      availableEnd,
                                      presentationid) 
           select(availabilityseq.nextval,
                  ?,
                  presentationDay,
                  presentationStart,
                  presentationEnd,
                  presentationid) 
                  from presentation where presentationid=?

            ");  
            ps.setString(1,Abean.getLecturerID());  
            ps.setString(2,Abean.getAvailableDay());  
            ps.setString(3,Abean.getAvailableStart()); 
            ps.setString(4,Abean.getAvailableEnd());  
            ps.setString(5,Abean.getPresentationID()); 
           // ps.setString(6,Abean.getAvailableID());
            ps.executeUpdate();  

            }
    catch(Exception e){
      System.out.println("add availability 2 failed: An Exception has occurred! " + e);
    }

不出所料，return错误

错误：java.sql.SQLException: Invalid column index

那么，我该如何插入带有额外列的子查询？

您需要将绑定变量值的设置与 SQL 文本中的绑定变量规范相匹配：

编辑 4 月 18 日： 从 select 子查询中删除括号

PreparedStatement ps=currentCon.prepareStatement("
            insert into availability (availableID,
                                      lecturerID,
                                      availableDay,
                                      availableStart,
                                      availableEnd,
                                      presentationid) 
           select availabilityseq.nextval,
                  ?,
                  presentationDay,
                  presentationStart,
                  presentationEnd,
                  presentationid
                  from presentation where presentationid=?
            ");  
            ps.setString(1,Abean.getLecturerID());  // match first "?"
            ps.setString(2,Abean.getPresentationID());    // match 2nd "?"
