Fabian Wilckens updated DRILL-1141:
-----------------------------------
Description:
Hi,
would be great to have a ISNUMERIC function in SQL because if you want to run a
count on self-described data there should be an option to check wether the
field is numeric and therefore countable.
if you have a CSV for example and the first line or some other lines (such as
in a pagebreak when importing) include the fieldnames and therefore
text-characters.
Would be great if a query such as: SELECT count(columns[0]) as number FROM
dfs.`bla` WHERE ISNUMERIC(columns[0])=1
Thanks
