[GitHub] [shardingsphere] FlyingZC opened a new issue, #27030: Support parsing Oracle CREATE LIBRARY sql
FlyingZC opened a new issue, #27030:
URL: https://github.com/apache/shardingsphere/issues/27030
# 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 LIBRARY [schema_name.]library_name
{IS | AS} 'file_path'
[AGENT 'agent_link'];
```
```sql
CREATE MATERIALIZED VIEW sum_sales_per_year_month_mv
BUILD IMMEDIATE
REFRESH FORCE ON DEMAND
ENABLE QUERY REWRITE AS
SELECT s.calendar_year, s.calendar_month_number,
SUM(s.amount_sold) AS sum_sales, COUNT(*) AS cnt
FROM sales_par_range_list s WHERE s.calendar_year > 1990
GROUP BY s.calendar_year, s.calendar_month_number;
```
```sql
CREATE LIBRARY app_lib as '${ORACLE_HOME}/lib/app_lib.so'
AGENT 'sales.hq.example.com';
```
```sql
CREATE MATERIALIZED VIEW LOG ON customers
PCTFREE 5
TABLESPACE example
STORAGE (INITIAL 10K);
```
```sql
CREATE MATERIALIZED VIEW LOG ON customers WITH PRIMARY KEY, ROWID;
```
# 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
