FlyingZC opened a new issue, #27690: URL: https://github.com/apache/shardingsphere/issues/27690
# 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 MASKING POLICY maskpol1 maskall ON LABEL(mask_lb1); --创建仅对用户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'场景下生效的脱敏策略。 ``` ```sql CREATE MASKING POLICY maskpol2 randommasking ON LABEL(mask_lb2) FILTER ON ROLES(dev_mask, bob_mask), APP(psql, gsql), IP('10.20.30.40', '127.0.0.0/24'); ``` ```sql CREATE SEQUENCE serial START 101; --删除序列。 ``` ```sql DROP SEQUENCE serial; ``` ```sql GRANT ALL PRIVILEGES TO joe; ``` # 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 -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
