Support parsing SQL Server SELECT -- 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 -- Find an event you want.
    p.name AS [Package-Name],
    o.object_type,
    o.name AS [Object-Name],
    o.description AS [Object-Descr],
    p.guid AS [Package-Guid]
FROM sys.dm_xe_packages AS p
INNER JOIN sys.dm_xe_objects AS o
    ON p.guid = o.package_guid
WHERE o.object_type = 'event' --'action'  --'target'
    AND p.name LIKE '%'
    AND o.name LIKE '%sql%'
ORDER BY p.name,
    o.object_type,
    o.name

SELECT value as tag, COUNT(*) AS [number_of_articles]
FROM Product
    CROSS APPLY STRING_SPLIT(Tags, ',')
GROUP BY value
HAVING COUNT(*) > 2
ORDER BY COUNT(*) DESC

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
