FlyingZC opened a new issue, #27152: URL: https://github.com/apache/shardingsphere/issues/27152
# 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 INSERT INTO remote_table@link as SELECT * FROM local_table; ``` ```sql LOCK TABLE interval_sales PARTITION FOR (TO_DATE('01-JUN-2007','dd-MON-yyyy')) IN SHARE MODE; ALTER TABLE interval_sales EXCHANGE PARTITION FOR (TO_DATE('01-JUN-2007','dd-MON-yyyy')) WITH TABLE interval_sales_jun_2007 INCLUDING INDEXES; ``` ```sql LOCK TABLE orders PARTITION FOR (TO_DATE('01-MAR-2007','dd-MON-yyyy')) IN SHARE MODE; ALTER TABLE orders EXCHANGE PARTITION FOR (TO_DATE('01-MAR-2007','dd-MON-yyyy')) WITH TABLE orders_mar_2007 WITH VALIDATION; ``` ```sql LOCK TABLE transactions PARTITION FOR(TO_DATE('31-JAN-2007','dd-MON-yyyy') IN SHARE MODE; ``` ```sql MAXLOGFILES 5 MAXLOGHISTORY 100 MAXDATAFILES 10 MAXINSTANCES 2 ARCHIVELOG CHARACTER SET WE8ISO8859P1 NATIONAL CHARACTER SET AL16UTF16 DATAFILE ``` # 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.
