Flavio Pompermaier commented on FLINK-17361:
--------------------------------------------
For the moment I can implement it without setting the read-only property of the
table and the user will just get an exception if it tries to insert into it.
Then, when the tables will have such a mechanism to specify the read-only
behavior it will be pretty easy to set it.
> Support creating of a JDBC table using a custom query
> -----------------------------------------------------
>
> Key: FLINK-17361
> URL: https://issues.apache.org/jira/browse/FLINK-17361
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Flavio Pompermaier
> Priority: Major
>
> In a long discussion on the mailing list it has emerged how it is not
> possible to create a JDBC table that extract data using a custom query.
> A temporary workaround could be to assign as 'connector.table' the target
> query.
> However this is undesirable.
> Moreover, in relation to https://issues.apache.org/jira/browse/FLINK-17360, a
> query could be actually a statement that requires parameters to be filled by
> the custom parameter values provider
