----------------------------
Description:
h3. Apache ShardingSphere
Apache ShardingSphere is a distributed database middleware ecosystem, including
2 independent products, ShardingSphere JDBC and ShardingSphere Proxy presently.
They all provide functions of data sharding, distributed transaction, and
database orchestration.
*Page*: [https://shardingsphere.apache.org|https://shardingsphere.apache.org/]
*Github*: [https://github.com/apache/shardingsphere]
h3. Background
ShardingSphere parser engine helps users parse a SQL to get the AST (Abstract
Syntax Tree) and visit this tree to get SQLStatement (Java Object). At present,
this parser engine can handle SQLs for `MySQL`, `PostgreSQL`, `SQLServer` and
`Oracle`, which means we have to understand different database dialect SQLs.
*More details*:
[https://shardingsphere.apache.org/document/current/en/features/sharding/principle/parse/]
h3. Task
This issue is to proofread the following definitions,
- All the DDL SQL definitions for Oracle *except for* ALTER, DROP, CREATE and
TRUNCATE.
- All the TCL (Transaction Control Language) SQL definitions for Oracle
- ALTER SYSTEM

As we have a basic [Oracle SQL syntax

we need you to find out the vague SQL grammar definitions and correct them
referring to Oracle DOC.
*Notice*, when you review these target SQLs above, you will find that these
definitions will involve some basic elements of Oracle SQL. No doubt, these
elements are included in this task as well.
