   I will provide the configuration again
   `CREATE TABLE tf_b_bank_info(idbigint(20) NOT NULL AUTO_INCREMENT,bankno varchar(25) COLLATE utf8_bin DEFAULT NULL, PRIMARY KEY (id`)
   ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='';
   
   CREATE TABLE tf_b_bank_user (
   id bigint(20) NOT NULL AUTO_INCREMENT,
   bank_id bigint(20) DEFAULT NULL COMMENT '银行类型:tf_b_bank_info的id',
   bankno varchar(255) COLLATE utf8_bin DEFAULT NULL COMMENT '银行卡号',
   DELETE_USER_NAME varchar(255) COLLATE utf8_bin DEFAULT NULL COMMENT '',
   PRIMARY KEY (id)
   ) ENGINE=InnoDB AUTO_INCREMENT=178026 DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='';``
   execute sql statement：
   `SELECT t.ID, t.BANKNO, tt.bankno banknono FROM tf_b_bank_user t JOIN tf_b_bank_info tt ON tt.id = t.bank_id`
   
   Execute the final result:
   When two tables have bankno fields at the same time, both table bankno fields will be converted to DELETE_USER_NAME fields
   
   java api configuration :
   `@Configuration
   @AutoConfigureBefore(DruidDataSourceAutoConfigure.class)
   public class ShardingConfigurer {
   
   @Bean
   public DataSource masterDataSource() {
       return DruidDataSourceBuilder.create().build();
   }
   
   @Bean
   @DependsOn({"masterDataSource"})
   @Primary
   public DataSource dataSource(DataSource masterDataSource) throws Exception {
   
       Map<String,DataSource> dataSourceMap = new HashMap<>();
       dataSourceMap.put("ds_0", masterDataSource);
   
       Properties properties = new Properties();
       properties.setProperty(SQL_SHOW.getKey(), "true");
   
       return ShardingSphereDataSourceFactory.createDataSource(
               dataSourceMap,
               Arrays.asList(
                       createEncryptRuleConfiguration())
               , properties);
   }
   
   
   public EncryptRuleConfiguration createEncryptRuleConfiguration() {
       Map<String, ShardingSphereAlgorithmConfiguration> encryptAlgorithmConfigs = new LinkedHashMap<>();
       Properties encryptProperties = new Properties();
       encryptProperties.setProperty("aes-key-value", "123456");
       encryptAlgorithmConfigs.put("aes", new ShardingSphereAlgorithmConfiguration("AES", encryptProperties));
   
   
       Collection<EncryptTableRuleConfiguration> tables = new LinkedList<>();
   
       Collection<EncryptColumnRuleConfiguration> columns = new LinkedList<>();
   
       EncryptColumnRuleConfiguration columnRuleConfiguration = new EncryptColumnRuleConfiguration("BANKNO","bankno_cipher",null,"bankno","aes");
       columns.add(columnRuleConfiguration);
   
       EncryptTableRuleConfiguration result = new EncryptTableRuleConfiguration("tf_b_bank_user", columns);;
   
       EncryptRuleConfiguration encryptRuleConfiguration = new EncryptRuleConfiguration(tables,encryptAlgorithmConfigs,false);
       return encryptRuleConfiguration;
   }`
