   > @wuqiaowu Could you paste your configuration?
   
   In my cases, I only need table sharding (no database sharding).
   
   ```
   <sharding:data-source id="shardingDataSource">
       <sharding:sharding-rule data-source-names="ds_master0, ds_master0_slave0" default-database-strategy-ref="noneShardingStrategy">
           <sharding:master-slave-rules>
               <sharding:master-slave-rule id="ds_ms0" master-data-source-name="ds_master0"
                                               slave-data-source-names="ds_master0_slave0" strategy-ref="randomStrategy"/>
               <!--   add another rule to skip "TableMetaDataInitializer.loadDefaultTables"’s executing  -->
               <sharding:master-slave-rule id="ds_ms1" master-data-source-name="ds_master0"
                                               slave-data-source-names="ds_master0_slave0" strategy-ref="randomStrategy"/>
           </sharding:master-slave-rules>
           <sharding:table-rules>
               <!--   use ds_ms0 explicitly -->
               <sharding:table-rule logic-table="table_a"
                                        actual-data-nodes="ds_ms0.table_a_$->{0..63}"
                                        table-strategy-ref="xxxxTableAStrategy"/>
               <sharding:table-rule logic-table="table_b"
                                        actual-data-nodes="ds_ms0.table_b_$->{['2020']}${['01','02','03','04','05','06','07','08','09','10','11','12']}"
                                        table-strategy-ref="xxxxTableBStrategy"/>
           </sharding:table-rules>
       </sharding:sharding-rule>
   </sharding:data-source>
   ```
