[GitHub] [shardingsphere] FlyingZC opened a new issue, #26970: Support parsing Oracle ALTER OPERATOR sql

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

FlyingZC opened a new issue, #26970:
URL: https://github.com/apache/shardingsphere/issues/26970

   # 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 OPERATOR Contains
     ADD BINDING (music.artist, music.artist) RETURN NUMBER
     USING music.contains;
   ```
   
   ```sql
   ALTER PROFILE prof LIMIT
    FAILED_LOGIN_ATTEMPTS 9
    PASSWORD_LOCK_TIME 10;
   ```
   
   ```sql
   ALTER PACKAGE [ schema. ] package package_compile_clause
   ```
   
   ```sql
   ALTER PROFILE app_user 
      LIMIT PASSWORD_REUSE_TIME DEFAULT
      PASSWORD_REUSE_MAX UNLIMITED;
   ```
   
   ```sql
   ALTER ROLLBACK SEGMENT
   CREATE ROLLBACK SEGMENT
   DROP ROLLBACK SEGMENT
   ```
   
   # 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
