[GitHub] [shardingsphere] FlyingZC opened a new issue, #27848: Support parsing openGauss CREATE sql
FlyingZC opened a new issue, #27848:
URL: https://github.com/apache/shardingsphere/issues/27848
# Background
Hi community,
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 openGauss SQL parsing in ShardingSphere.
More details:
https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/
# Task
This issue is to support more openGauss sql parse, as follows:
```sql
CREATE RESOURCE LABEL adt_lb0 add TABLE(tb_for_audit);
--对数据库执行create操作创建审计策略
```
```sql
CREATE AUDIT POLICY adt1 PRIVILEGES CREATE;
--对数据库执行select操作创建审计策略
```
```sql
CREATE AUDIT POLICY adt2 ACCESS SELECT;
--仅审计记录用户dev_audit和bob_audit在执行针对adt_lb0资源进行的create操作数据库创建审计策略
```
```sql
CREATE AUDIT POLICY adt3 PRIVILEGES CREATE ON LABEL(adt_lb0) FILTER ON ROLES(dev_audit, bob_audit);
--仅审计记录用户dev_audit和bob_audit,客户端工具为psql和gsql，IP地址为'10.20.30.40', '127.0.0.0/24'，在执行针对adt_lb0资源进行的select、insert、delete操作数据库创建审计策略。
```
```sql
CREATE AUDIT POLICY adt4 ACCESS SELECT ON LABEL(adt_lb0), INSERT ON LABEL(adt_lb0), DELETE FILTER ON ROLES(dev_audit, bob_audit), APP(psql, gsql), IP('10.20.30.40', '127.0.0.0/24');
```
# Process
1. First confirm that this is a correct openGauss sql syntax, if not please leave a message under the issue and ignore it;
2. Compare SQL definitions in Official 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 Statement 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 openGauss SQLs
