[GitHub] [shardingsphere] FlyingZC opened a new issue, #26986: Support parsing Oracle ALTER TABLE sql

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

FlyingZC opened a new issue, #26986:
URL: https://github.com/apache/shardingsphere/issues/26986

   # 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 TABLE print_media MODIFY NESTED TABLE ad_textdocs_ntab
      RETURN AS VALUE;
   ```
   
   ```sql
   ALTER TABLE print_media_part 
      ADD PARTITION p4 VALUES LESS THAN (400)
      LOB(ad_photo, ad_composite) STORE AS (TABLESPACE omf_ts1)
      LOB(ad_sourcetext, ad_finaltext) STORE AS (TABLESPACE omf_ts1)
      NESTED TABLE ad_textdocs_ntab STORE AS nt_p3;
   ```
   
   ```sql
   ALTER TABLE print_media_part ADD PARTITION p3 VALUES LESS THAN (400)
     LOB(ad_photo, ad_composite) STORE AS (TABLESPACE omf_ts1)
     LOB(ad_sourcetext, ad_finaltext) STORE AS (TABLESPACE omf_ts2)
     NESTED TABLE ad_textdocs_ntab STORE AS nt_p3;
   ```
   
   ```sql
   ALTER TABLE sales ADD CONSTRAINT sales_time_fk
   FOREIGN KEY (time_id) REFERENCES times (time_id)
   ENABLE NOVALIDATE;
   ```
   
   ```sql
   ALTER TABLE sales ADD CONSTRAINT sales_time_fk
   FOREIGN KEY (time_id) REFERENCES times (time_id)
   ENABLE VALIDATE;
   ```
   
   # 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
