[GitHub] [shardingsphere] tuichenchuxin opened a new issue #13137: support parsing SHOW SLAVE HOSTS for mysql

tuichenchuxin opened a new issue #13137:
URL: https://github.com/apache/shardingsphere/issues/13137


   Hi community,
   
   This issue can be a good first try.
   
   ## Aim
   support parse mysql administration statements sql `SHOW SLAVE HOSTS`
   
   ## Basic Qualifications
   - java
   - maven
   - antlr4
   
   ## Detail
   We have completed the clone rule in DALStatement.g4.
   But have not yet implement the visit method in `shardingsphere-sql-parser/shardingsphere-sql-parser-dialect/shardingsphere-sql-parser-mysql/src/main/java/org/apache/shardingsphere/sql/parser/mysql/visitor/statement/impl/MySQLDALStatementSQLVisitor.java`
   To complete this issue, I think we should complete these steps:
   - Create `MySQLShowSlaveHostsStatement` class in this package `org.apache.shardingsphere.sql.parser.sql.dialect.statement.mysql.dal`
   - Add rule in `shardingsphere-sql-parser/shardingsphere-sql-parser-engine/src/main/java/org/apache/shardingsphere/sql/parser/core/database/visitor/SQLVisitorRule.java`
   - Implement the visit method in `shardingsphere-sql-parser/shardingsphere-sql-parser-dialect/shardingsphere-sql-parser-mysql/src/main/java/org/apache/shardingsphere/sql/parser/mysql/visitor/statement/impl/MySQLDALStatementSQLVisitor.java`. 
   - Finally, add test for parse clone statement in `shardingsphere-test` module
   ## Example FYI
   - Refer to this merged pr：https://github.com/apache/shardingsphere/pull/12979/files
