[GitHub] [shardingsphere] FlyingZC opened a new issue, #27700: Support parsing openGauss ALTER sql

["FlyingZC (via GitHub)" <gi...@apache.org>]

FlyingZC opened a new issue, #27700:
URL: https://github.com/apache/shardingsphere/issues/27700

   # 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
    ALTER MASKING POLICY maskpol1 REMOVE randommasking ON LABEL(mask_lb2);
   
   --修改脱敏策略maskpol1，修改一项脱敏方式
   
   ```
   
   ```sql
    ALTER MASKING POLICY maskpol1 MODIFY randommasking ON LABEL(mask_lb1);
   
   --修改脱敏策略maskpol1使之仅对用户dev_mask和bob_mask，客户端工具为psql和gsql，IP地址为'10.20.30.40'，'127.0.0.0/24'场景生效。
   
   ```
   
   ```sql
    ALTER MASKING POLICY maskpol1 MODIFY (FILTER ON ROLES(dev_mask, bob_mask), APP(psql, gsql), IP('10.20.30.40', '127.0.0.0/24'));
   
   --修改脱敏策略maskpol1，使之对所有用户场景生效
   
   ```
   
   ```sql
    ALTER MASKING POLICY maskpol1 DROP FILTER;
   
   --禁用脱敏策略maskpol1
   
   ```
   
   ```sql
    ALTER MASKING POLICY maskpol1 DISABLE;
   ```
   
   # 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
