[GitHub] [shardingsphere] FlyingZC opened a new issue, #27116: Support parsing Oracle CREATE TABLESPACE sql
FlyingZC opened a new issue, #27116:
URL: https://github.com/apache/shardingsphere/issues/27116
# 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 securespace
DATAFILE '/u01/app/oracle/oradata/orcl/secure01.dbf' SIZE 100M
ENCRYPTION
DEFAULT STORAGE(ENCRYPT);
```
```sql
CREATE TABLESPACE lmt2 DATAFILE 'lmt_file3.dbf' SIZE 100m REUSE
EXTENT MANAGEMENT LOCAL;
CREATE TABLE lmt_table2 (col1 NUMBER, col2 VARCHAR2(20))
TABLESPACE lmt2 STORAGE (INITIAL 2m MAXSIZE 100m);
```
```sql
CREATE TABLESPACE lobtbs1 DATAFILE '/your/own/data/directory/lobtbs_1.dat'
SIZE 2000M REUSE ONLINE NOLOGGING DEFAULT STORAGE (MAXEXTENTS UNLIMITED);
ALTER TABLESPACE lobtbs1 ADD DATAFILE
'/your/own/data/directory/lobtbs_2.dat' SIZE 2000M REUSE;
CREATE TABLE print_media_backup
(product_id NUMBER(6),
ad_id NUMBER(6),
ad_composite BLOB,
ad_sourcetext CLOB,
ad_finaltext CLOB,
ad_fltextn NCLOB,
ad_textdocs_ntab textdoc_tab,
ad_photo BLOB,
ad_graphic BLOB,
ad_header adheader_typ)
NESTED TABLE ad_textdocs_ntab STORE AS textdocs_nestedtab5
LOB(ad_sourcetext) STORE AS (TABLESPACE lobtbs1 CHUNK 32768 PCTVERSION 0
NOCACHE NOLOGGING
STORAGE(INITIAL 100M NEXT 100M MAXEXTENTS
UNLIMITED PCTINCREASE 0));
```
```sql
CREATE TABLESPACE sysaux DATAFILE 'sysaux01.dbf'
SIZE 500M REUSE
EXTENT MANAGEMENT LOCAL
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;
```
```sql
CREATE TABLESPACE tbs_02
DATAFILE 'diskb:tbs_f5.dbf' SIZE 500K REUSE
AUTOEXTEND ON NEXT 500K MAXSIZE 100M;
```
# 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
