["FlyingZC (via GitHub)" <gi...@apache.org>]

FlyingZC opened a new issue, #26976:
URL: https://github.com/apache/shardingsphere/issues/26976

   # Background
   Hi community,
   This issue is for #26878.
   
   ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract Syntax Tree) and visit this tree to get SQLStatement (Java Object). Currently, we are planning to enhance the support for Oracle SQL parsing in ShardingSphere.
   
   More details:
   https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/
   
   # Task
   This issue is to support more oracle sql parse, as follows:
   ```sql
   ALTER SYSTEM SET ENCRYPTION KEY ["certificate_ID"] IDENTIFIED BY "password"
   ```
   
   ```sql
   ALTER SYSTEM SET EVENTS 'CLIENTID_OVERWRITE';
   ```
   
   ```sql
   ALTER SYSTEM SET EVENTS 'CLIENTID_OVERWRITE OFF';
   ```
   
   ```sql
   ALTER TABLE DROP COLUMN COL2;
   ```
   
   ```sql
   ALTER TABLE HR.EMPLOYEES
      ADD SUPPLEMENTAL LOG GROUP emp_fulltime (EMPLOYEE_ID, LAST_NAME, 
      DEPARTMENT_ID);
   ```
   
   # Process
   1. First confirm that this is a correct oracle sql syntax, if not please ignore;
   2. Compare SQL definitions in Oficial SQL Doc and ShardingSphere SQL Doc;
   3. If there is any difference in ShardingSphere SQL Doc, please correct them by referring to the Official SQL Doc;
   4. Run mvn install the current_file_module;
   5. Check whether there are any exceptions. If indeed, please fix them. (Especially xxxVisitor.class);
   6. Add new corresponding SQL case in SQL Cases and expected parsed result in Expected Statment XML;
   7. 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
