URL: https://github.com/apache/shardingsphere/issues/18556
mybatis3.5.9 + sharding jdbc5.1.1
sql：
insert into qy_barrage(cus_no, send_time, barrage, create_time, update_time,
create_user, update_user)
values (#{cusNo}, #{sendTime}, #{barrage}, #{createTime}, #{updateTime},
#{createUser}, #{updateUser})
database
CREATE TABLE qy_barrage_aaa_2022 (
id bigint unsigned NOT NULL,

but when I change the actual-data-nodes from
ds0.qy_barrage_$->{'(。)*'}$->{2022..9999} to ds0.qy_barrage ->{2022..9999}, it
works correctly!!! why?
