-------------------------------
Summary: Select column range
Key: DRILL-5574
URL: https://issues.apache.org/jira/browse/DRILL-5574
Project: Apache Drill
Issue Type: Improvement
Components: SQL Parser
Affects Versions: 1.10.0
Environment: All
Reporter: Humair M
Priority: Trivial
Ability to select column ranges would be useful. When dealing with wide files
being able to select sequential range of columns without specifying each column
will improve the usability.
So instead of this:
select columns[1], columns[2], columns[3], columns[8], columns[9], columns[10]
from `data.csv`
use this:
select columns[1-3], columns[8-10] from `data.csv`
On a sidenote for extremely wide files (10K columns) the only way to query the
data or load it into native tables is to chop it up first as Java is runnint
out of the constant limits (error: too many constants) when querying the file
directly or creating a table from it. This issue has been reported elsewhere.
