FlyingZC opened a new issue, #27803: URL: https://github.com/apache/shardingsphere/issues/27803
# 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 FOREIGN table bmsql_oorder ( o_w_id integer not null, o_d_id integer not null, o_id integer not null, o_c_id integer not null, o_carrier_id integer, o_ol_cnt integer, o_all_local integer, o_entry_d timestamp, primary key (o_w_id, o_d_id, o_id) ); create index bmsql_oorder_index1 on bmsql_oorder(o_w_id, o_d_id, o_c_id, o_id) ; ``` ```sql benchmarksql=# select * from customer; ``` ```sql benchmarksql=# alter table customer rename to customer_bk; ``` ```sql benchmarksql=# create foreign table customer (x int, y int); CREATE FOREIGN TABLE benchmarksql=# select * from customer; ``` ```sql $ gs_restore -C -d benchmarksql customer.dump -p 16000 restore operation successful total time: 24 ms Check that the data was imported successfully. benchmarksql=# select * from customer; ``` # 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.
