FlyingZC opened a new issue, #26965: URL: https://github.com/apache/shardingsphere/issues/26965
# 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 INDEX cost_ix RENAME PARTITION p3 TO p3_Q3; ``` ```sql ALTER INDEX cost_ix SPLIT PARTITION p2 AT (1500) INTO ( PARTITION p2a TABLESPACE tbs_01 LOGGING, PARTITION p2b TABLESPACE tbs_02); ``` ```sql ALTER INDEX emp_ename STORAGE (NEXT 40); ``` ```sql ALTER INDEX hgidx ADD PARTITION p5; ``` ```sql ALTER INDEX po_xmlindex_ix PARAMETERS('DROP PATH TABLE'); ``` # 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 -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
