FlyingZC opened a new issue, #27858: URL: https://github.com/apache/shardingsphere/issues/27858
# 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 TEXT SEARCH CONFIGURATION ngram3 (copy=ngram2) WITH (gram_size = 2, grapsymbol_ignore = false); --添加类型映射。 ``` ```sql ALTER TEXT SEARCH CONFIGURATION ngram2 ADD MAPPING FOR multisymbol WITH simple; --创建用户joe。 ``` ```sql CREATE USER joe IDENTIFIED BY 'xxxxxxxxx'; --修改文本搜索配置的所有者。 ``` ```sql ALTER TEXT SEARCH CONFIGURATION ngram2 OWNER TO joe; --修改文本搜索配置的schema。 ``` ```sql ALTER TEXT SEARCH CONFIGURATION ngram2 SET SCHEMA joe; --重命名文本搜索配置。 ``` # 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.
