Support parsing openGauss INSERT sql

[FlyingZC]

Background

Hi community,

ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract Syntax Tree) and visit this tree to get SQLStatement (Java Object). Currently, we are planning to enhance the support for openGauss SQL parsing in ShardingSphere.

More details: https://shardingsphere.apache.org/document/current/en/reference/sharding/parse/

Task

This issue is to support more openGauss sql parse, as follows:

 INSERT INTO creditcard_info VALUES (2, 'joy','6219985678349800033'); 
 INSERT 0 1 

// 插入数据
 int rc4 = stmt.executeUpdate("INSERT INTO creditcard_info VALUES (1,'joe','6217986500001288393');"); 
 // 查询加密表
 ResultSet rs = null; 
 rs = stmt.executeQuery("select * from creditcard_info where name = 'joe';"); 
 // 关闭语句对象
 stmt.close();

CREATE  [ LARGE ] SEQUENCE name [ INCREMENT [ BY ] increment ]
    [ MINVALUE minvalue | NO MINVALUE | NOMINVALUE ] [ MAXVALUE maxvalue | NO MAXVALUE | NOMAXVALUE] 
    [ START [ WITH ] start ] [ CACHE cache ] [ [ NO ] CYCLE | NOCYCLE ] 
    [ OWNED BY { table_name.column_name | NONE } ];

 CREATE SEQUENCE serial
 START 101
 CACHE 20;

 DROP SEQUENCE serial cascade;

Process

1. First confirm that this is a correct openGauss 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 openGauss SQLs
