[GitHub] [shardingsphere] tuichenchuxin opened a new issue, #20397: support parse ALTER RESOURCE COST

tuichenchuxin opened a new issue, #20397:
URL: https://github.com/apache/shardingsphere/issues/20397

   Hi community,
   
   This issue is for #20305.
   ref to #6480
   
   ## Background
   ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract Syntax Tree) and visit this tree to get SQLStatement (Java Object). At present, this parser engine can handle SQLs for `MySQL`, `PostgreSQL`, `SQLServer`, `openGauss` and `Oracle`, which means we have to understand different database dialect SQLs.
   More details: 
   https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/
   
   ## Task
   This issue is to support more sql parse. 
   
   - [ ] ALTER RESOURCE COST [doc](https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/ALTER-RESOURCE-COST.html#GUID-92DCB41E-5113-4722-8A54-E90E1AE7DB54)
   
   ## Process
   1. Compare SQL definitions in [Oficial SQL Doc](https://docs.oracle.com/en/database/oracle/oracle-database/18/lnpls/plsql-language-elements.html#GUID-285DFAEE-1A34-4248-BA4B-2591476A0C3C) and [ShardingSphere SQL Doc](https://github.com/apache/shardingsphere/tree/master/shardingsphere-sql-parser/shardingsphere-sql-parser-dialect/shardingsphere-sql-parser-oracle/src/main/antlr4/imports/oracle).
   2. If there is any difference in ShardingSphere SQL Doc, please correct them by referring to the Official SQL Doc.
   3. Run `mvn install the current_file_module`.
   4. Check whether there are any exceptions. If indeed, please fix them. (`Especially xxxVisitor.class`).
   5. Add new corresponding SQL case in SQL Cases and expected parsed result in Expected Statment XML.
   6. Run SQLParserParameterizedTest to make sure no exceptions.
   
   ## Relevant Skills
   1. Master JAVA language
   2. Have a basic understanding of Antlr g4 file
   3. Be familiar with Oracle SQLs
