FlyingZC opened a new issue, #27801: URL: https://github.com/apache/shardingsphere/issues/27801
# 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 USER user2 IDENTIFIED BY 'XXXXXXXXX'; ``` ```sql -- （1）使用普通账户alice，连接全密态数据库， [cmd] gsql -U alice -h $host -p $port -d $database -C -r -- （2）使用本语法创建客户端加密主密钥(CMK)对象 openGauss=> CREATE CLIENT MASTER KEY a_cmk WITH (KEY_STORE = localkms, KEY_PATH = "key_path_value", ALGORITHM = RSA_2048); openGauss=> CREATE CLIENT MASTER KEY another_cmk WITH (KEY_STORE = localkms, KEY_PATH = "another_path_value", ALGORITHM = SM2); ``` ```sql - site 是employee的SET类型的字段 ``` ```sql show create trigger before_ins_stmt_trig; ``` ```sql CREATE RESOURCE LABEL schm_lb ADD SCHEMA (schema_for_label); CREATE RESOURCE LABEL tb_lb ADD TABLE (schema_for_label.table_for_label); CREATE RESOURCE LABEL col_lb ADD COLUMN (schema_for_label.table_for_label.column_for_label); CREATE RESOURCE LABEL multi_lb ADD SCHEMA (schema_for_label), TABLE (table_for_label); ``` # 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.
