wuyunfeng opened a new issue #5005:
URL: https://github.com/apache/incubator-doris/issues/5005
**Is your feature request related to a problem? Please describe.**
1. Elasticsearch users maybe use `Logstash` transform and transmit data to
ES, the `Logstash` would add `@` leading field name to ES index mapping. If we
create table with `@` leading column, Doris would throw `Incorrect column name`
when user create those table at present
2. Since Doris keep consistent with `Mysql protocol`, Those `column` name
with `@` leading is legal， I think Doris would supprt this feature by adding
backticks `` to wrap those column name
**Describe the solution you'd like**
Change the `column` validation rules to support `@` leading column name.
Such as:
```
CREATE EXTERNAL TABLE `es_10` (
`@k3` bigint(20) NULL COMMENT "",
`@k1` boolean NULL COMMENT "",
`@k2` varchar(20) NULL COMMENT ""
) ENGINE=ELASTICSEARCH
COMMENT "ELASTICSEARCH"
```
**Describe alternatives you've considered**
**Additional context**
Not sure about the impact on Olap Engine
