Norris Lee created DRILL-1294:
---------------------------------
Summary: Columns of views created from files are of data type 'ANY'
Key: DRILL-1294
URL: https://issues.apache.org/jira/browse/DRILL-1294
Project: Apache Drill
Issue Type: Bug
Reporter: Norris Lee
When you execute a select * query against a view created from a file (eg. from
JSON or CSV), the data type of the columns returned reflect the nature of the
data in the column (varchar, bigint, etc).
But in INFORMATION_SCHEMA.COLUMNS, the data type is listed as 'ANY'.
Note that if it was casted during the create view statement, then
INFORMATION_SCHEMA.COLUMNS will display it correctly as whatever it was casted
to.
