[jira] [Created] (FLINK-9864) Make timestamp extraction more
flexible in SQL Client
Timo Walther created FLINK-9864:
-----------------------------------
Summary: Make timestamp extraction more flexible in SQL Client
Key: FLINK-9864
URL: https://issues.apache.org/jira/browse/FLINK-9864
Project: Flink
Issue Type: New Feature
Components: Table API & SQL
Reporter: Timo Walther
Assignee: Timo Walther
Currently, a timestamp must be in the top-level of a possibly nested row and must have a certain format. We should think about making this more flexible to cover most of the use cases.
A first solution could be to allow a DOT operator syntax: {{myfield.nested.timestamp}}
Other cases might be:
- The time could also be split into several field
- Or needs to be parsed using a [date format syntax|https://ci.apache.org/projects/flink/flink-docs-master/dev/table/sql.html#date-format-specifier].
