## Question
**For English only**, other languages will not accept.
when I use with hintManager mode
define a java class public class HintShardingStrategy implements HintShardingAlgorithm<String>
I write rule in hint-databases-only.yaml like this
shardingRule:
tables:
quartz_user_monitor:
databaseStrategy:
hint: #Hint分片策略
algorithmClassName: com.smarttree.manage.config.mybatis.HintShardingStrategy
biz_fee:
databaseStrategy:
hint: #Hint分片策略
algorithmClassName: com.smarttree.manage.config.mybatis.HintShardingStrategy
biz_official_notice:
databaseStrategy:
hint: #Hint分片策略
algorithmClassName: com.smarttree.manage.config.mybatis.HintShardingStrategy
case_info:
databaseStrategy:
hint: #Hint分片策略
algorithmClassName: com.smarttree.manage.config.mybatis.HintShardingStrategy
sys_fee:
databaseStrategy:
hint: #Hint分片策略
algorithmClassName: com.smarttree.manage.config.mybatis.HintShardingStrategy
use sql in mapper.xml
like select * from a left join b on xxx left join c on xxx
but it does not work good. can not go into dosharding function.
when I tried with single table like delete or insert .it work good. can go into dosharding function
delete * from a where xxx
insert
what am i wrong?
By the way:
I change mode with PreciseSharding like this:
public class StdDatabaseShardingAlgorithm implements PreciseShardingAlgorithm<String> {
mutiy table select do not work too.
what am i wrong?

thanks a lot!
another question
Can I define only the default sharding database rules with not define tableRule
I want the table structure of each instance is exactly the same based on the every database splitting operation of tenantid
Is there any way to use table rules without defining each table
I try to comment out the table definition in the tablerule, but console log:
org.apache.shardingsphere.underlying.common.config.exception.ShardingSphereConfigurationException: Cannot find table rule and default data source with logic table: 'QRTZ_TRIGGERS'
QRTZ_TRIGGERS must define in shardingRule.tables.QRTZ_TRIGGERS ?
have a default way to define all tables?

my userd version is 5.0.0-RC1-SNAPSHOT with master branch source.
Will future versions support the subquery or the support plan？
Special business methods are complex to write
for example subquery:
SELECT * FROM (
SELECT
`tbl_biz`.*,
`tmp`.`payer_name` AS `payer_name`
FROM
`biz_fee_unipay` `tbl_biz`
LEFT JOIN
(
SELECT
`t1`.`type` AS `payer_type`,
`t1`.`name` AS `payer_type_name`,
`t2`.`value` AS `payer_id`,
`t2`.`name` AS `payer_name`
FROM
(
`sys_dict_type` `t1`
LEFT JOIN `sys_dict_data` `t2` ON ((

@phoema , Which version of ShardingSphere did you use? Can you provide a complete configuration.
