## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response anymore 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? master (5.0.1-SNAPSHOT) ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior ### Actual behavior org.apache.shardingsphere.infra.binder.segment.table.TablesContext#findTableNameFromMetaData() can find the correct table name for column names. ### Reason analyze (If you can)  ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. I wrote a test case in `org.apache.shardingsphere.infra.binder.segment.table.TablesContextTest` as follows: ``` @Test public void assertFindTableNameWhenColumnSegmentOwnerAbsentAndSchemaMetaDataContainsColumnInUpperCase() { // When the sql is "SELECT * FROM TABLE_1 AS TBL_1 JOIN TABLE_2 AS TBL_2 ON COL_IN_TBL1 = TBL_2.COL" // The table name in table segment will be the same case in SQL which is in uppercase SimpleTableSegment tableSegment1 = createTableSegment("TABLE_1", "TBL_1"); SimpleTableSegment tableSegment2 = createTableSegment("TABLE_2", "TBL_2"); TableMetaData tableMetaData = createTableMetaData("TABLE_1", Arrays.asList("COL")); ShardingSphereSchema schema = new ShardingSphereSchema(Arrays.asList(tableMetaData).stream().collect(Collectors.toMap(TableMetaData::getName, v -> v))); ColumnProjection columnProjection = createColumnProjection(null, "COL", null); Map<String, String> actual = new TablesContext(Arrays.asList(tableSegment1, tableSegment2)).findTableName(Collections.singletonList(columnProjection), schema); assertFalse(actual.isEmpty()); assertThat(actual.get("col"), is("TABLE_1")); } private TableMetaData createTableMetaData(String tableName, List<String> columnNames) { return new TableMetaData( tableName, columnNames.stream().map(colName -> new ColumnMetaData(colName, 0, false, false, true)).collect(Collectors.toList()), Collections.EMPTY_LIST); } ``` and the test result is : ``` java.lang.AssertionError at org.junit.Assert.fail(Assert.java:86) at org.junit.Assert.assertTrue(Assert.java:41) at org.junit.Assert.assertFalse(Assert.java:64) at org.junit.Assert.assertFalse(Assert.java:74) at org.apache.shardingsphere.infra.binder.segment.table.TablesContextTest.assertFindTableNameWhenColumnSegmentOwnerAbsentAndSchemaMetaDataContainsColumnInUpperCase(TablesContextTest.java:109) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:564) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:69) at com.intellij.rt.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:33) at com.intellij.rt.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:235) at com.intellij.rt.junit.JUnitStarter.main(JUnitStarter.java:54) ``` ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
