> Key: FLINK-15334
> URL: https://issues.apache.org/jira/browse/FLINK-15334
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.10.0
> Reporter: Leonard Xu
> Assignee: Leonard Xu
> Priority: Major
> Fix For: 1.10.0
>
>
> If user defined a DDL like:
> "CREATE TABLE orders (\n" +
> " order_id STRING,\n" +
> " item STRING,\n" +
> " currency STRING,\n" +
> " amount INT,\n" +
> " amount_kg as amount * 1000,\n" +
> " order_time TIMESTAMP(3),\n" +
> " ts as order_time + INTERVAL '1' SECOND,\n" +
> " WATERMARK FOR ts AS ts\n" +
> ") WITH (\n" +
> which generated columns(eg:amount_kg) defined before custom
> columns(eg:order_time) will get wrong properties.
> in this case, we still use index 5 for column order_time and the new index
> should be 4 after prune generated column.
