Can you give me the INSERT SQL?

useGeneratedKeys，when insert sql the last column value is null,cause NullPointerException

Is the last column generated Key column？And is its value null?
@zhangfenghuang

zhangfenghuang · 2019-04-24T05:56:29Z

like this：
insert into xxxxx (xxxxx, xxxxx,
xxxx, xxxx, xxxx,
xxxx, xxx, xxxx,
xxx, delete_flag, create_emp,
create_org, create_time, update_time
)
values (#{xxxx,jdbcType=VARCHAR}, #{xxxx,jdbcType=VARCHAR},
#{xxxx,jdbcType=VARCHAR}, #{xxxx,jdbcType=VARCHAR}, #{xxxx,jdbcType=VARCHAR},
#{xxx,jdbcType=VARCHAR}, #{xxxx,jdbcType=INTEGER}, #{xxx,jdbcType=SMALLINT},
#{xxx,jdbcType=VARCHAR}, #{deleteFlag,jdbcType=BIT}, #{createEmp,jdbcType=VARCHAR},
#{createOrg,jdbcType=VARCHAR}, #{createTime,jdbcType=TIMESTAMP}, #{updateTime,jdbcType=TIMESTAMP}
)

column "updateTime" is null，cause NullPointerException
remove "updateTime“，inserted

@zhangfenghuang

No，generated column is ”id“， insert sql not contains ”id“

tristaZero · 2019-04-25T06:29:42Z

I did the following test, but no exception happened.
ShardingRule Configuration

shardingRule:
  tables:
    t_order:
      actualDataNodes: ds_${0..1}.t_order_${0..1}
      tableStrategy:
        inline:
          shardingColumn: order_id
          algorithmExpression: t_order_${order_id % 2}
      keyGenerator:
        type: SNOWFLAKE
        column: order_id

Table structure

CREATE TABLE `t_order_1` (
  `order_id` bigint(20) NOT NULL,
  `user_id` int(11) NOT NULL,
  `status` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`order_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

SQL

insert into t_order values(1,null), (2,2);

Do you think this example fits your scenario?

By the way, can you set the props sql.show=true? So that we can view log to check the rewritten SQLs are correct or not.

Thanks for your reply, can you provide your CREATE TABLE SQL ?
@zhangfenghuang

tristaZero · 2019-04-29T04:44:01Z

@zhangfenghuang Hi, can you use SpringNameSpace + Mybatis + ShardingSphere examples to try to make your exception appeared?
I try to run the examples above, but i can not get exception.

Or maybe you can provide your demo git url, so i can run your example in my computer.

Waiting for your reply.
