FlyingZC opened a new issue, #27131: URL: https://github.com/apache/shardingsphere/issues/27131
# 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 CREATE trigger FOR dml_event_clause ON view COMPOUND TRIGGER INSTEAD OF EACH ROW IS BEGIN statement; END INSTEAD OF EACH ROW; ``` ```sql CROSSCHECK BACKUP; CROSSCHECK COPY; ``` ```sql CREATE or REPLACE FUNCTION CrashTestRating(Model VARCHAR2, Year VARCHAR2) return NUMBER is BEGIN -- Derive CrashTestRating from other relational tables using Model -- -- and Year values. -- return 5; END CrashTestRating; ``` ```sql DB_RECOVERY_FILE_DEST = <mount point or Oracle ASM Disk Group> DB_RECOVERY_FILE_DEST_SIZE = <disk space quota> ``` ```sql DB_RECOVERY_FILE_DEST_SIZE = 10G ``` # 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.
