[GitHub] [shardingsphere] FlyingZC opened a new issue, #27771: Support parsing openGauss REFRESH sql
FlyingZC opened a new issue, #27771:
URL: https://github.com/apache/shardingsphere/issues/27771
# 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
REFRESH MATERIALIZED VIEW mv;
REFRESH MATERIALIZED VIEW
--查询物化视图结果。
```
```sql
select * from mv;
c1 | c2
----+----
1 | 1
2 | 2
3 | 3
4 | 4
(4 rows)
--删除物化视图。
```
```sql
DROP MATERIALIZED VIEW mv;
```
```sql
ALTER DATABASE music CONNECTION LIMIT= 10;
--将music名称改为music4。
```
```sql
ALTER DATABASE music RENAME TO music4;
--将数据库music2的所属者改为tom。
```
# 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
