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 ROLE [doc](https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/ALTER-ROLE.html#GUID-85543272-EAF4-4FED-A921-AD9868102C39) ## 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 -- This is an automated message from the Apache Git Service.
