Describe your use case

In Oceanbase, under the Oracle tenant, uppercase is created in lowercase. Some SQL editors will automatically perform syntax conversion when querying, but in FlinkSQL, if table names and column names are all lowercase in DDL, while writing data in FlinkSQL must be uppercase. Unlike the habit of definition at the same time, writing in lowercase will fail.

Describe the solution you'd like

We can add parameters in oceanbase connector to automate it.
