MOBIN commented on FLINK-35985:
-------------------------------
Currently, flink-cdc only provides the substr function. Although substr is the
abbreviation of substring, it is common in flink/spark/doris to provide both
substr and substring functions for users to use.
I think flink-cdc should also provide both substr and substring functions.
What do you think? [~xiqian_yu] [~Leonard]
If possible, please assign it to me. Thank you

> Project: Flink
> Issue Type: Bug
> Components: Flink CDC
> Reporter: yux
> Priority: Major
>
> Currently, one could not write `SUBSTRING(str FROM idx FOR len)` in the way
> that suggested in the doumentations[1], while the workable function,
> `SUBSTR(str, idx, len)`, isn't mentioned anywhere.
> Either the code or the docs needs update to avoid confusing users.
