与Statement.RETURN_GENERATED_KEYS一起使用时出现PreparedStatement问题

Question

当我尝试将PreparedStatement与Statement.RETURN_GENERATED_KEYS一起使用时，我不知道为什么PreparedStatement对象需要额外的参数。我已经用Google搜索了所有可能的字符串，但没有得到任何回复。

以下是我用于插入记录的代码。

StringBuilder headerSql = new StringBuilder();
headerSql.append("insert into TABLE_XXX(subscriber_id,company_id,stg_inv_id,inv_loc_id,count_date,count_status,count_type,creation_user,creation_date,update_user,update_date) \n");
headerSql.append("(select ?,?,XXXX_PK.NEXTVAL,?,sysdate,0,0,?,sysdate,?,sysdate from dual \n");
headerSql.append("where not exists(select 1 from TABLE_XXX where subscriber_id=? and company_id=? and inv_loc_id=? and count_status=0 and count_type=0)) \n"); 
String stgInvId=null; 
PreparedStatement ps = null;
ResultSet rs = null;
try {           
    ps = con.prepareStatement(headerSql.toString(), Statement.RETURN_GENERATED_KEYS);
    ps.setString(1,Integer.toString(IDObj.getSubscriberID()));
    ps.setString(2,Integer.toString(IDObj.getCompanyID()));
    ps.setString(3,locId);
    ps.setString(4,IDObj.getUserLogin());
    ps.setString(5,IDObj.getUserLogin());
    ps.setString(6,Integer.toString(IDObj.getSubscriberID()));
    ps.setString(7,Integer.toString(IDObj.getCompanyID()));
    ps.setString(8,locId);
    ps.executeUpdate();
    rs = ps.getGeneratedKeys();
    rs.next();
    stgInvId=rs.getString("stg_inv_id");
} catch (Exception e) {                 
    System.out.println(headerSql.toString());
    e.printStackTrace();            
}

下面是绑定的参数列表：

正如您在上面所看到的，我现在不是从添加最后一个参数的位置以及我需要传递给我的值。请指导我们。

下面是Stacktrace：

Answer 1

oracle DB RETURN_GENERATED_KEYS以这种方式工作。

1）RETURN_GENERATED_KEYS标志

PreparedStatement ps = con.prepareStatement("INSERT INTO XXX(  A, B) VALUES ( xxx_s.nextval, 'aaa')",Statement.RETURN_GENERATED_KEYS);      
    ps.executeUpdate();        
    ResultSet      rs = ps.getGeneratedKeys();
    while(rs.next()) {
        System.out.println(rs.getString(1));
    }

Oracle不知道哪个列是自动生成的，并且它正在返回rowid。 returning rowid into :?附加到插入

2）列列表。

PreparedStatement ps = con.prepareStatement("INSERT INTO XXX(  A, B) VALUES ( xxx_s.nextval, 'aaa')",new String[]{"A"});        
        ps.executeUpdate();        
        ResultSet      rs = ps.getGeneratedKeys();
        while(rs.next()) {
            System.out.println(rs.getString(1));
        }
        con.close();

在这种情况下，我们明确指定自动生成的列。 returning a into :?附加到插入

在这两种情况下，要访问生成的列，您必须使用位置访问权限。不支持按列名访问。

但是你正在尝试insert as select。法规转换为

insert into xxxy  select * from xxxy returning rowid into :var ; 

oracle db不支持此语句。异常ORA-00933: SQL command not properly ended is raised。
