## 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? 5.0.0-alpha ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior the SQL listed below should be parsed correctly ### Actual behavior throw org.antlr.v4.runtime.NoViableAltException: null ### Reason analyze (If you can) It seems union all in subquery is not supported in mysql. ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. use pagehelper , the count sql is : SELECTcount(0) from ( SELECT id FROM table1 UNION ALL SELECT id FROM table2 ) t； line 1:406 no viable alternative at input 'SELECTcount(0)FROM(SELECTidFROtable1UNION' org.antlr.v4.runtime.NoViableAltException: null at org.antlr.v4.runtime.atn.ParserATNSimulator.noViableAlt(ParserATNSimulator.java:2026) ~[antlr4-runtime-4.7.2.jar:4.7.2] at org.antlr.v4.runtime.atn.ParserATNSimulator.execATN(ParserATNSimulator.java:467) ~[antlr4-runtime-4.7.2.jar:4.7.2] at org.antlr.v4.runtime.atn.ParserATNSimulator.adaptivePredict(ParserATNSimulator.java:393) ~[antlr4-runtime-4.7.2.jar:4.7.2] ### Example codes for reproduce this issue (such as a github link). public class ShardingTests { @Test void testSql() { String sql = " select count(0)\n" + " from (\n" + " SELECT id\n" + " FROM table1\n" + " UNION ALL\n" + " SELECT id\n" + " FROM table2\n" + " ) t\n"; StandardSQLParserEngine standardSQLParserEngine = new StandardSQLParserEngine("Mysql"); standardSQLParserEngine.parse(sql, true); } -- This is an automated message from the Apache Git Service.
