FlyingZC opened a new issue, #27730: URL: https://github.com/apache/shardingsphere/issues/27730
# 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 // 注册out类型的参数，类型为复合类型,格式为“schema.typename”。 cs.registerOutParameter(2, Types.STRUCT, "public.compfoo"); ``` ```sql cs.execute(); ``` ```sql PGobject result = (PGobject)cs.getObject(2); // 获取out参数 result.getValue(); // 获取复合类型字符串形式值。 result.getArrayValue(); //获取复合类型数组形式值，以复合数据类型字段顺序排序。 result.getStruct(); ``` ```sql cs.close(); ``` ```sql // 在数据库创建复合数据类型。 CREATE TYPE compfoo AS (f1 int, f3 text); // 在数据库中已创建了如下存储过程，它带有out参数。 create or replace procedure test_proc ( psv_in in compfoo, psv_out out compfoo ) as begin psv_out := psv_in; end; ``` # 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.
