Description

As seen in FLINK-23751, the single rowtime column check can occur also during collecting and printing which is not important there as watermarks as not used.

The exception is also misleading as it references a DataStream:

[ERROR] Could not execute SQL statement. Reason:
org.apache.flink.table.api.TableException: Found more than one rowtime field: [bidtime, window_time] in the query when insert into 'default_catalog.default_database.Unregistered_Collect_Sink_8'.
Please select the rowtime field that should be used as event-time timestamp for the DataStream by casting all other fields to TIMESTAMP.
