Daniel Barclay (Drill) updated DRILL-2519:
------------------------------------------
Description:
The INFORMATION_SCHEMA.COLUMNS table does not have all data from the
<interval_qualifier> of an INTERVAL type descriptor.
In particular, it does not have enough information to implement
DatabaseMetaData.getColumns()'s COLUMN_SIZE column for INTERVAL types.
(It does not have the starting and ending units, so we can't distinguish
between INTERVAL HOUR TO MINUTE and INTERVAL HOUR TO SECOND--which have
different lengths (COLUMN_SIZE) because their string representations have
different fields.)
