FlyingZC opened a new issue, #27860: URL: https://github.com/apache/shardingsphere/issues/27860
# 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 select pg_stat_reset_shared('bgwriter'); select pg_stat_reset(); ``` ```sql ALTER INDEX tpcds.ds_ship_mode_t1_index2 UNUSABLE; --重建索引。 ``` ```sql ALTER INDEX tpcds.ds_ship_mode_t1_index2 REBUILD; --删除一个现有的索引。 ``` ```sql CREATE INDEX ds_ship_mode_t1_index2 ON tpcds.ship_mode_t1(SUBSTR(SM_CODE,1 ,4)) INVISIBLE; --删除表。 ``` ```sql CREATE TABLESPACE example1 RELATIVE LOCATION 'tablespace1/tablespace_1'; ``` # 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.
