[GitHub] [shardingsphere] FlyingZC opened a new issue, #27819: Support parsing openGauss ROLLBACK [ sql

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

FlyingZC opened a new issue, #27819:
URL: https://github.com/apache/shardingsphere/issues/27819

   # 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
   ROLLBACK [ WORK | TRANSACTION ] TO [ SAVEPOINT ] savepoint_name;
   ```
   
   ```sql
   SELECT pg_catalog.ledger_hist_repair(schema_name text,table_name text);
   ```
   
   ```sql
   SELECT pg_catalog.ledger_gchain_repair(schema_name text,table_name text);
   ```
   
   ```sql
    CREATE TABLE tpcds.customer_address_bak AS TABLE tpcds.customer_address;
   
   --删除tpcds.customer_address_bak中ca_address_sk小于14888的职员。
   
   ```
   
   ```sql
    DELETE FROM a,b USING tpcds.customer_address a,tpcds.customer_address_bak b where a.ca_address_sk = b.ca_address_sk and a.ca_address_sk < 50;
   或者
   
   ```
   
   # 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
