ranqiqiang updated FLINK-22538:
-------------------------------
Description:
If user writes some flink-sql include (source query .... sink ) , then
how to check the sql is right ?
such as
# the field nums is equals ?
# the field type is match ?
# udf is exist ?
Because user executes sql will be wrong ! and found many errors, It's to late
.
I just want to check the sql-errors out before to execute sql!
Now,how to get the check api or method?
I think it's a usefull idea !
I don't know alibaba blink could do this ?
thanks
