---------------------------------
Summary: 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
I use sql-client to create a table with keyword-escaped columns and
computed_column_expression columns, 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}

{code}
I also did some tests, the following can run:
{code:java}
CREATE TABLE source_kafka (
log STRING,
`aaaaa` BIGINT,
pt as proctime()
)
CREATE TABLE source_kafka (
log STRING,
`time` BIGINT
)
CREATE TABLE source_kafka (
log STRING,
pt as proctime()
){code}
can not run:
`time` , `select`, `string`
