[I] Support parsing SQL Server SELECT s.session_id, sql [shardingsphere]

["FlyingZC (via GitHub)" <gi...@apache.org>]

FlyingZC opened a new issue, #29161:
URL: https://github.com/apache/shardingsphere/issues/29161

   # Background
   Hi community.
   This issue is for #29149.
   
   The ShardingSphere SQL parser engine helps users to parse SQL to create the AST (Abstract Syntax Tree) and visit the AST to get SQLStatement (Java Object). Currently, we are planning to enhance the support for `SQL Server` SQL parsing in ShardingSphere.
   
   More details:
   https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/
   
   # Task
   This issue is to support more `SQL Server` sql parsing, as follows:
   ```sql
   SELECT s.session_id, JSON_OBJECT('security_id':s.security_id, 'login':s.login_name, 'status':s.status) as info
   FROM sys.dm_exec_sessions AS s
   WHERE s.is_user_process = 1
   ```

   ```sql
   SELECT TOP 10 hash_unique_bigint_id
   FROM dbo.TelemetryDS
   WHERE Timestamp BETWEEN @StartTime AND @EndTime
   GROUP BY hash_unique_bigint_id
   ORDER BY MAX(max_elapsed_time_microsec) DESC
   ```

   ```sql
   INSERT INTO AdventureWorks2022.Production.Location
                        (Name, CostRate, Availability, ModifiedDate)
                           VALUES (NEWID(), .5, 5.2, GETDATE())
   ```

   ```sql
   SELECT name
       , size / 128.0 - CAST(FILEPROPERTY(name, 'SpaceUsed') AS INT) / 128.0 AS AvailableSpaceInMB
   FROM sys.database_files
   ```

   ```

   # Process
   1. First confirm that this is a correct `SQL Server` 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 `SQL Server` SQLs
