求助！！delete 删除分片表报错：no database selected！！！！！！！！

各位大佬，mycat2搭建好,创建分片表后delete 删除分片表报错：no database selected,查询、修改、新增都正常，就删除报错，是什么原因？
建表语句如下：
CREATE TABLE db1.orders(
id BIGINT NOT NULL AUTO_INCREMENT,
order_type INT,
customer_id INT,
amount DECIMAL(10,2),
PRIMARY KEY(id),
KEY id (id)
)ENGINE=INNODB DEFAULT CHARSET=utf8
dbpartition BY mod_hash(customer_id) tbpartition BY mod_hash(customer_id)
tbpartitions 1 dbpartitions 4;

删除语句如下：
delete from db1.orders where id=1;

后台日志报错如下：
