Can you also provide some examples of what you are trying to accomplish?
It seems like you might be saying that you want a virtual attribute for the
entire path rather than individual pieces? Also remember that partition
pruning can also be done if you're using Parquet files without all the dirN
Hi Andries,
I've already tried writing where and case statements but none of them
worked unfortunately. It's still:
DATA_READ ERROR: Error parsing JSON - You tried to write a VarChar type
when you are using a ValueWriter of type NullableIntWriterImpl.
When I try this on sqlline, I can confirm
Does this system option not work:
ALTER SESSION SET `drill.exec.functions.cast_empty_string_to_null` = true;
The reason the bug was marked INVALID is that SQL engines (not sure about
the spec) don't allow casting from empty string to number. The system
option above is supposed to allow changing
This is a limitation of really late appearing fields. Right now, depending
on the situation, if a value doesn't show up in the first ~4k, we assume
that the value is BigInt. I think a developer is working on improving this
behavior right now. I'll ping them to see when we might have a fix.

thank you, it's greatly appreciated.

Hi,
I have nothing meaningful to add but I had share that this BigInt
assumption has caused more grief than any other single feature in Drill.
I would go so far as to say that the "type intolerance" and lack of
"sensible conversion" is the biggest hurdle on the way to fulfilling the

Hi,
I have some json files that I want to transform to parquet.
We have been doing this without any issues but this time around I get this
exception:

This kind of errors usually happens when there is an unsupported schema
change in the json files, but you should be able to reproduce the error
with just a select statement. Can you share both queries you tried (the
failing CTAS and the successful SELECT *) ?
Thanks

Hi,
Both statements select everything but the CTAS statement included a date
filter + date order.
The date field is always the same (extended json format date ISO) and is
always present so I can say, with 100% certainty, that there is no schema
change involved.
