Hi,
I would like to know if a solution exists to force the mode to "NOT
NULL" for a data type when creating a parquet via "CREATE TABLE AS".
I know how to force the mode to "NULL" using the NULLIF function
- SELECT modeof(3) => NOT NULL
- SELECT modeof(NULLIF(3,CAST(NULL AS integer))) =>
Appreciate your detailed answer.
I have tried to put the JSON part in the drill-override.conf with
absolutely no result, but it's may be a particular case.
First, I ended up confirm by reading
https://github.com/apache/drill/blob/master/exec/java-exec/src/main/resources/drill-module.conf

Hi,
I would like to know if it's possible to configure options at Drill startup
I know that it's possible to do ALTER SESSION/SYSTEM in command line and
if it's SYSTEM the value will be retained even after a reboot.
I can use the webinterface to change the value of the options

Hi,
I have a source (.csv) with multi-encoding (it's [bs]ad but can't change
that).
When I try to apply a regexp_replace on a field
(like...regexp_replace(`myfield`,'...','...')...) I get an error
- Error: SYSTEM ERROR: MalformedInputException: Input length = 1
For example, I have a case due to
s.`/data/bar.csv`;

Hi,
I have read that in SELECT from multiple sources (SELECT * FROM
tmp.`myfile*`), the files are treated in random order.
But I don't understand why the processing of (parquet) files that do not
have the same columns is not homogeneous.
Example (on Drill 1.14) :
CREATE TABLE tmp2.`mytable1` AS
Hi,
Thanks for details.
It's the point, I don't want to write additional metadata,
but just organize the parquet file to have more useful stats.
In a simple GROUP BY it's possible to not SELECT some of "grouped" column.
(Example SELECT a, b FROM ... GROUP BY a, b, c;)
In the same way, I think it
