   Before report a bug, make sure you have:
   
   - Searched open and closed [GitHub issues](https://github.com/sharding-sphere/sharding-sphere/issues).
   - Read documentation: [ShardingSphere Doc](http://shardingsphere.io/document/current/en/overview/).
   
   Please pay attention on issues you submitted, because we maybe need more details. 
   If no response **more than 7 days** and we cannot reproduce it on current information, we will **close it**.
   
   Please answer these questions before submitting your issue. Thanks!
   
   ### Which version of ShardingSphere did you use?
   4.0.0-RC2
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   Sharding-JDBC
   ### Expected behavior
   sql like:
   ```
   select id customerId, entity_card_num entityCardNum, mobile, NAME
           from customer where company_id = ? and id not in (
           SELECT distinct customer_id
           FROM customer_account_change_record cacr inner join customer c on cacr.company_id = c.company_id and c.id =
           cacr.customer_id and cacr.company_id = ?
           WHERE cacr.created between ? and ?
           and cacr.company_id = ?
           and cacr.card_type = 1
           ) and enabled_status = 1
           order by created desc
               limit ?,?
   ```
   `ConditionSegment(name:created, owner:cacr, operator:BETWEEN)`
   
   ### Actual behavior
   getTableName will return 'customer' not 'customer_account_change_record'
   ### Reason analyze (If you can)
   ```
   private String getTableName(final ShardingTableMetaData shardingTableMetaData, final ShardingRule shardingRule, final Tables tables, final ConditionSegment conditionSegment) {
           Collection<String> shardingLogicTableNames = shardingRule.getShardingLogicTableNames(tables.getTableNames());
           if (tables.isSingleTable() || tables.isSameTable() || 1 == shardingLogicTableNames.size() || shardingRule.isAllBindingTables(shardingLogicTableNames)) {
               return tables.getSingleTableName();
           }
           if (conditionSegment.getColumn().getOwner().isPresent()) {
               Optional<Table> table = tables.find(conditionSegment.getColumn().getOwner().get());
               return table.isPresent() ? table.get().getName() : "";
           } else {
               return getTableNameFromMetaData(shardingTableMetaData, tables, conditionSegment.getColumn().getName());
           }
       }
   ```
   match the if condition `1 == shardingLogicTableNames.size()` then direct return the first table name
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   
   ### Example codes for reproduce this issue (such as a github link).
