在运行此程序时，我收到以下异常
以下是要传输数据的数据库模型。
如何解决这个问题？
1 个答案:
答案 0 :(得分：2)
在INSERT INTO buffer.append中，你使用两次名称RESLV_TM。
buffer.append(" INCDT_START_TM, INCDT_ST_TXT, OPEN_BY_GRP_TXT, RESLV_TM, RESLV_DT, "); //RESOLVED=RESLV_DT
buffer.append(" RESLV_TM, RESLV_AT_LEVEL_TXT, SVRTY_TXT, LOB_TXT, "); //Resolved_Date=null
正如db告诉你的那样，你不能在INSERT命令中使用两次相同的列名。
您需要更改其中一个
