Proposed changes
Adjust the field naming rules when creating tables.
The original table field rules are letters or underscores or @ characters as the first letter, followed by a maximum of 63 characters, and the total cannot exceed 64 characters. However, in many industries, such as the financial industry, the length of the derived fields often exceeds 64 characters, so adjust the regular The rules are from 64 characters to 128 characters. Many users load data from Hive to Doris through appearance or BrokerLoad. Arabic numerals can be used as the first letter in the Hive table, so the regular rules are adjusted to support Arabic numerals as the first letter.
