Support parsing SQL Server INSERT INTO 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:

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

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

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)

link

UPDATE dbo.Table1   
SET c2 = c2 + d2   
FROM dbo.Table2   
WHERE CURRENT OF abc

link

UPDATE Cities  
SET Location.SetXY(23.5, 23.5)  
WHERE Name = 'Anchorage'

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
