Yiwen Tu updated FLINK-17174:
-----------------------------
Description:
I read data from kafka source name and the source table has the fields of 'ts'
which has the row time attributes, after that I add an column whose type is
int and default value is 0. After that, the kafka source will be join with a
table. And the code is below:
!image-2020-04-16-13-08-33-752.png|width=2329,height=253!
The Error is :
!image-2020-04-16-13-08-59-149.png!
But when I use SqlQuery, it works:
