FlyingZC opened a new issue, #27115:
URL: https://github.com/apache/shardingsphere/issues/27115

   # 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 lmtbsb DATAFILE '/u02/oracle/data/lmtbsb01.dbf' SIZE 50M
       EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K;
   ```
   
   ```sql
   CREATE TABLE time_range_sales
      ( prod_id        NUMBER(6)
      , cust_id        NUMBER
      , time_id        DATE
      , channel_id     CHAR(1)
      , promo_id       NUMBER(6)
      , quantity_sold  NUMBER(3)
      , amount_sold    NUMBER(10,2)
      )
   PARTITION BY RANGE (time_id)
    (PARTITION SALES_1998 VALUES LESS THAN 
(TO_DATE('01-JAN-1999','DD-MON-YYYY')),
     PARTITION SALES_1999 VALUES LESS THAN 
(TO_DATE('01-JAN-2000','DD-MON-YYYY')),
     PARTITION SALES_2000 VALUES LESS THAN 
(TO_DATE('01-JAN-2001','DD-MON-YYYY')),
     PARTITION SALES_2001 VALUES LESS THAN (MAXVALUE)
    );
   ```
   
   ```sql
   CREATE TABLESPACE omf_ts2 DATAFILE AUTOEXTEND OFF;
   ```
   
   ```sql
   CREATE TABLESPACE securespace
     DATAFILE '/home/oracle/oracle3/product/11.1.0/db_1/secure01.dbf'
       SIZE 150M
       ENCRYPTION
       DEFAULT STORAGE(ENCRYPT);
   ```
   
   ```sql
   CREATE TABLESPACE securespace
   DATAFILE '/home/user/oradata/secure01.dbf'
   SIZE 150M
   ENCRYPTION USING '3DES168'
   DEFAULT STORAGE(ENCRYPT);
   ```
   
   # 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
