URL: https://github.com/apache/shardingsphere/pull/34943
Fixes #31499
Changes proposed in this pull request:
This pull request modify the parsing of the following sql:
```sql
CREATE MATERIALIZED VIEW mv1 BUILD IMMEDIATE
CREATE MATERIALIZED VIEW mv1 REFRESH COMPLETE
CREATE MATERIALIZED VIEW mv1 REFRESH ON SCHEDULE EVERY 2 HOUR STARTS
"2023-12-13 21:07:09"
CREATE MATERIALIZED VIEW mv1 KEY(k1,k2)
```
For the completeness of SQL syntax, I added a simple SELECT at the end to
ensure they work properly.
```sql
CREATE MATERIALIZED VIEW mv1 BUILD IMMEDIATE AS SELECT k1, k2 FROM
test_table;
CREATE MATERIALIZED VIEW mv1 REFRESH COMPLETE AS SELECT k1, k2 FROM
test_table;
CREATE MATERIALIZED VIEW mv1 REFRESH ON SCHEDULE EVERY 2 HOUR STARTS
"2023-12-13 21:07:09" AS SELECT k1, k2 FROM test_table;
CREATE MATERIALIZED VIEW mv1 KEY(k1,k2) AS SELECT k1, k2 FROM test_table;
```
Since the original Doris DDL did not have Materialized Views, I referred to
[Materialized
Views](https://doris.apache.org/docs/query-acceleration/materialized-view/async-materialized-view/functions-and-demands)
and added parsing syntax in DDLStatement.g4.
