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 -- 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.
