Change JDBC table creation syntax

We should create JDBC table without data source.

Change syntax of creating JDBC table statement as
CREATE TABLE [IF NOT EXISTS] [db_name.]table_name
(col_name data_type
[constraint_specification]
[COMMENT 'col_comment']
[, ...]
)
[COMMENT 'table_comment']
STORED BY JDBC
TBLPROPERTIES ('key1'='value1', 'key2'='value2', ...)
