Jark Wu commented on FLINK-16068:
---------------------------------
cc [~danny0405], could you help to take a look at this? It seems there is a bug
in the SQL parser when the column name is a keyword and a computed column in
the definition.
> table with keyword-escaped columns and computed_column_expression columns

> Key: FLINK-16068
> URL: https://issues.apache.org/jira/browse/FLINK-16068
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Client
> Affects Versions: 1.10.0
> Reporter: pangliang
> Priority: Major
>
> I use sql-client to create a table with keyword-escaped column and
> computed_column_expression column, like this:
> {code:java}
> CREATE TABLE source_kafka (
> log STRING,
> `time` BIGINT,
> pt as proctime()
> ) WITH (
> 'connector.type' = 'kafka',
> 'connector.version' = 'universal',
> 'connector.topic' = 'k8s-logs',
> 'connector.startup-mode' = 'latest-offset',
> 'connector.properties.zookeeper.connect' =
> 'zk-1.zk:2181,zk-2.zk:2181,zk-3.zk:2181/kafka',
> 'connector.properties.bootstrap.servers' = 'kafka.default:9092',
> 'connector.properties.group.id' = 'testGroup',
> 'format.type'='json',
> 'format.fail-on-missing-field' = 'true',
> 'update-mode' = 'append'
> );
> {code}
> Then I simply used it :
> {code:java}
> SELECT * from source_kafka limit 10;{code}
> got an exception:
> {code:java}
