FlyingZC opened a new issue, #27839: URL: https://github.com/apache/shardingsphere/issues/27839
# 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 1.执行gs_preinstall（高斯部署脚本） 2.执行scrlock_preinstall.sh，并根据提示输入root密码 3.执行gs_install（高斯部署脚本） 4.以OS用户进入SCP_TO_PATH目录后，执行scrlock_install.sh，执行source ~/.bashrc 5.重新拉起高斯数据库(cm_ctl stop; ``` ```sql CREATE WEAK PASSWORD DICTIONARY WITH VALUES ('password1'), ('password2'); ``` ```sql DROP WEAK PASSWORD DICTIONARY; ``` ```sql SET ROLE joe PASSWORD "abc@1234"; ``` ```sql analyze; ANALYZE ``` # 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.
