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 #Test VALUES (N'OC', N'Ounces', GETDATE())

link

INSERT INTO #Test SELECT * FROM Production.UnitMeasure

link

SELECT COUNT(*) AS [Number of rows] FROM #Test

link

INSERT INTO #Test VALUES (N'OC', N'Ounces', GETDATE())

link

INSERT INTO #Test SELECT * FROM Production.UnitMeasure

link

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

Could you please let me know what DAL and RL acronym mean? I figured out that DML (Data Manipulation Language), DDL (Data Definition Language), TCL (Transaction Control Language) and DCL (Data Control Language) are acronyms related to SQL statements, but have problem to understand DAL and RL. Thank you for your time!
