Oracle高手进入帮忙解决个奇怪的问题
代码如：
conn=DBConn.getConn();
pst=conn.prepareStatement(sb.toString());
pst.setString(1, gp.getServiceID());
pst.setString(2, gp.getServiceUrl());
pst.setString(3, gp.getReadme());
pst.setString(4, gp.getVersions());
pst.setString(5, "1");
pst.setString(6, "");
pst.setTimestamp(7, new Timestamp(System.currentTimeMillis()));
i = pst.executeUpdate();
rs = pst.getGeneratedKeys();
if (rs != null&&rs.next()) {
return rs.getInt(1);
}
我是想插入数据库后获取该数据的id，原来在MySql上是问题的，迁移到了Oracle之后就报错了，错误如下，高手看下：
