FlyingZC opened a new issue, #27117: URL: https://github.com/apache/shardingsphere/issues/27117
# 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 TABLESPACE tbs_01 DATAFILE 'tbs_f2.dbf' SIZE 40M ONLINE; ``` ```sql CREATE TRIGGER set_empno_ctx_trig AFTER LOGON ON DATABASE BEGIN sysadmin_ctx.set_empno_ctx_pkg.set_empno; END; ``` ```sql CREATE TABLESPACE tbs_03 DATAFILE 'tbs_f03.dbf' SIZE 20M LOGGING; ``` ```sql CREATE TABLESPACE tbs_04 DATAFILE 'file_1.dbf' SIZE 10M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K; ``` ```sql CREATE TABLE salestable (s_productid NUMBER, s_saledate DATE, s_custid NUMBER, s_totalprice NUMBER) PARTITION BY RANGE(s_saledate) INTERVAL(NUMTOYMINTERVAL(1,'MONTH')) STORE IN (tbs1,tbs2,tbs3,tbs4) (PARTITION sal05q1 VALUES LESS THAN (TO_DATE('01-APR-2005', 'DD-MON-YYYY')) TABLESPACE tbs1, PARTITION sal05q2 VALUES LESS THAN (TO_DATE('01-JUL-2005', 'DD-MON-YYYY')) TABLESPACE tbs2, PARTITION sal05q3 VALUES LESS THAN (TO_DATE('01-OCT-2005', 'DD-MON-YYYY')) TABLESPACE tbs3, PARTITION sal05q4 VALUES LESS THAN (TO_DATE('01-JAN-2006', 'DD-MON-YYYY')) TABLESPACE tbs4, PARTITION sal06q1 VALUES LESS THAN (TO_DATE('01-APR-2006', 'DD-MON-YYYY')) TABLESPACE tbs1, PARTITION sal06q2 VALUES LESS THAN (TO_DATE('01-JUL-2006', 'DD-MON-YYYY')) TABLESPACE tbs2, PARTITION sal06q3 VALUES LESS THAN (TO_DATE('01-OCT-2006', 'DD-MON-YYYY')) TABLESPACE tbs3, PARTITION sal06q4 VALUES LESS THAN (TO_DATE('01-JAN-2007', 'DD-MON-YYYY')) TABLESPACE tbs4); ``` # 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.
