Support parsing SQL Server SELECT d.name, sql

[FlyingZC]

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:

SELECT d.name, d.owner_sid, sl.name
FROM sys.databases AS d
JOIN sys.sql_logins AS sl
ON d.owner_sid = sl.sid

SELECT DISTINCT user.FirstName, user.LastName
INTO ms_user
FROM user INNER JOIN (
    SELECT * FROM ClickStream WHERE cs.url = 'www.microsoft.com'
    ) AS ms
ON user.user_ip = ms.user_ip

SELECT {[Measures].[Internet Sales Count], [Measures].[Internet Sales-Sales Amount]} ON COLUMNS, 
{[Product].[Product Line].[Product Line].MEMBERS} ON ROWS
FROM [Analysis Services Tutorial]
WHERE [Sales Territory].[Sales Territory Country].[Australia]

INSERT INTO #tmpdbs ([dbid], [dbname], [isdone])
SELECT database_id, name, 0 FROM master.sys.databases (NOLOCK) WHERE is_read_only = 0 AND state = 0

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
