[I] Support parsing SQL Server INSERT INTO sql [shardingsphere]

[via GitHub]

FlyingZC opened a new issue, #29182:
URL: https://github.com/apache/shardingsphere/issues/29182

   # 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:

   # Task
   This issue is to support more `SQL Server` sql parsing, as follows:
   ```sql
   INSERT INTO #tmpdbs ([dbid], [dbname], [isdone])
   SELECT database_id, name, 0 FROM master.sys.databases (NOLOCK) WHERE 
is_read_only = 0 AND state = 0
   ```

   ```sql
   SELECT [name], COUNT(l.database_id) AS 'vlf_count' 
   FROM sys.databases AS s
   CROSS APPLY sys.dm_db_log_info(s.database_id) AS l
   GROUP BY [name]
   HAVING COUNT(l.database_id) > 100
   ```

   ```sql
   UPDATE dbo.Table2   
   SET dbo.Table2.ColB = dbo.Table2.ColB + dbo.Table1.ColB  
   FROM dbo.Table2   
       INNER JOIN dbo.Table1   
       ON (dbo.Table2.ColA = dbo.Table1.ColA)
   ```

   FROM dbo.Table2

   # 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
