FlyingZC opened a new issue, #27643: URL: https://github.com/apache/shardingsphere/issues/27643
# 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 Connection conn = DriverManager.getConnection("url","user","password") ; ``` ```sql int commitAborts = 0; while (commitAborts < RETRY_LIMIT) { try { stmt =db.stmtPaymentUpdateDistrict; stmt.setDouble(1, 100); stmt.setInt(2, 1); stmt.setInt(3, 1); stmt.executeUpdate(); db.commit(); break; } catch (SQLException se) { if(se != null && se.getMessage().contains("could not serialize access due to concurrent update")) { log.error("commmit abort = " + se.getMessage()); commitAborts++; continue; }else { db.rollback(); } break; ``` ```sql --创建一个发布，发布两个表中所有更改。 CREATE PUBLICATION mypublication FOR TABLE users, departments; --创建一个发布，发布所有表中的所有更改。 CREATE PUBLICATION alltables FOR ALL TABLES; --创建一个发布，只发布一个表中的INSERT操作。 CREATE PUBLICATION insert_only FOR TABLE mydata WITH (publish = 'insert'); --修改发布的动作。 ALTER PUBLICATION insert_only SET (publish='insert,update,delete'); --向发布中添加表。 ALTER PUBLICATION insert_only ADD TABLE mydata2; --删除发布。 DROP PUBLICATION insert_only; ``` ```sql CREATE TABLESPACE tpcds_local RELATIVE LOCATION 'tablespace/tablespace_1' ; ``` ```sql ALTER DATABASE db_tpcc SET search_path TO pa_catalog,public; ``` # 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.
