xiaoma20082008 commented on issue #2193: Table doesn't exist when sharding value in different datasource with in expression URL: https://github.com/apache/incubator-shardingsphere/issues/2193#issuecomment-519484038 hello , I have the same problems, when will you solve this issue, and publish a release version ? I guess the problem may happen at the TableRule class about actualDataNodes property. I have an 8 shard databases and 64 shard columns. the actualDataNodes string just like this: ``` "ds_${0..8}.tb_${0..63}" ``` Expect actualDataNodes just like this: ``` ds_0-> tb_0, tb_8, tb_16, tb_24, tb_32, tb_40, tb_48, tb_56 ds_1-> tb_1, tb_9, tb_17, tb_25, tb_33, tb_41, tb_49, tb_57 ds_2-> tb_2, tb_10, tb_18, tb_26, tb_34, tb_42, tb_50, tb_58 ds_3-> tb_3, tb_11, tb_19, tb_27, tb_35, tb_43, tb_51, tb_59 ds_4-> tb_4, tb_12, tb_20, tb_28, tb_36, tb_44, tb_52, tb_60 ds_5-> tb_5, tb_13, tb_21, tb_29, tb_37, tb_45, tb_53, tb_61 ds_6-> tb_6, tb_14, tb_22, tb_30, tb_38, tb_46, tb_54, tb_62 ds_7-> tb_7, tb_15, tb_23, tb_31, tb_39, tb_47, tb_55, tb_63 ``` Here is a code for reference only ```java private Map<String, List<DataNode>> convertDataNodes(List<DataNode> dataNodes) { LinkedHashMap<String, List<DataNode>> result = new LinkedHashMap<>(); for (DataNode dataNode : dataNodes) { List<DataNode> nodes = result.get(dataNode.getDataSourceName()); if (nodes == null) { nodes = new ArrayList<>(); result.put(dataNode.getDataSourceName(), nodes); } nodes.add(dataNode); } final int size = result.size(); int i = 0; for (Map.Entry<String, List<DataNode>> e : result.entrySet()) { final List<DataNode> tables = e.getValue(); final List<DataNode> list = new ArrayList<>(size); // notice here for (int j = i; j < tables.size(); j += size) { list.add(tables.get(j)); } e.setValue(list); i++; } return result; } ```
