FlyingZC opened a new issue, #27800: URL: https://github.com/apache/shardingsphere/issues/27800
# 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 gsql> select generate_wdr_report(begin_snap_id Oid, end_snap_id Oid, int report_type, int report_scope, int node_name ); ``` ```sql --创建jack用户。 CREATE USER jack PASSWORD 'XXXXXXXX'; --删除用户jack在数据库template1上的所有连接。 CLEAN CONNECTION TO ALL FOR DATABASE template1 TO USER jack; --删除用户jack的所有连接。 CLEAN CONNECTION TO ALL TO USER jack; --删除在数据库gaussdb上的所有连接。 CLEAN CONNECTION TO ALL FORCE FOR DATABASE gaussdb; --删除用户jack。 DROP USER jack; ``` ```sql CREATE OR REPLACE PROCEDURE retry_basic ( IN x INT) AS BEGIN INSERT INTO t1 (a) VALUES (x); INSERT INTO t1 (a) VALUES (x+1); END; / ``` ```sql CREATE SCHEMA schema_name [ AUTHORIZATION user_name ] ; ``` ```sql CREATE USER user1 IDENTIFIED BY 'XXXXXXXX'; ``` # 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.
