[GitHub] [shardingsphere] FlyingZC opened a new issue, #27163: Support parsing Oracle SET EXTPROC_DLLS=ONLY:DLL1:DLL2 sql
FlyingZC opened a new issue, #27163:
URL: https://github.com/apache/shardingsphere/issues/27163
# 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
SET EXTPROC_DLLS=ONLY:DLL1:DLL2
```
```sql
SET SERVEROUTPUT ON
DECLARE
enqueue_options DBMS_AQ.enqueue_options_t;
message_properties DBMS_AQ.message_properties_t;
message_handle RAW(16);
message test.message_typ;
BEGIN
message := test.message_typ(001, 'ORANGE', 'ORANGE enqueued first.');
DBMS_AQ.ENQUEUE(
queue_name => 'test.obj_queue',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
message := test.message_typ(001, 'ORANGE', 'ORANGE also enqueued second.');
DBMS_AQ.ENQUEUE(
queue_name => 'test.obj_queue',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
message := test.message_typ(001, 'YELLOW', 'YELLOW enqueued third.');
DBMS_AQ.ENQUEUE(
queue_name => 'test.obj_queue',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
message := test.message_typ(001, 'VIOLET', 'VIOLET enqueued fourth.');
DBMS_AQ.ENQUEUE(
queue_name => 'test.obj_queue',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
message := test.message_typ(001, 'PURPLE', 'PURPLE enqueued fifth.');
DBMS_AQ.ENQUEUE(
queue_name => 'test.obj_queue',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
message := test.message_typ(001, 'PINK', 'PINK enqueued sixth.');
DBMS_AQ.ENQUEUE(
queue_name => 'test.obj_queue',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
COMMIT;
END;
```
```sql
SET SERVEROUTPUT ON
DECLARE
dequeue_options DBMS_AQ.dequeue_options_t;
message_properties DBMS_AQ.message_properties_t;
message_handle RAW(16);
message test.message_typ;
BEGIN
dequeue_options.navigation := DBMS_AQ.FIRST_MESSAGE;
DBMS_AQ.DEQUEUE(
queue_name => 'test.obj_queue',
dequeue_options => dequeue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
DBMS_OUTPUT.PUT_LINE('From Sender No.'|| message.sender_id);
DBMS_OUTPUT.PUT_LINE('Subject: '||message.subject);
DBMS_OUTPUT.PUT_LINE('Text: '||message.text);
COMMIT;
END;
```
```sql
SET UNTIL TIME 'Nov 15 2004 09:00:00';
SET UNTIL SEQUENCE 9923;
SET UNTIL RESTORE POINT before_update;
```
```sql
SET XMLOptimizationCheck ON
```
# 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

Close the issue, `SET SERVEROUTPUT` can only be executed in `sqlplus`.
