info

Chris Westin updated DRILL-2519:
--------------------------------
Affects Version/s: 0.8.0
> INFORMATION_SCHEMA.COLUMNS is missing <interval_qualifier> info
> ---------------------------------------------------------------
>
> Key: DRILL-2519
> URL: https://issues.apache.org/jira/browse/DRILL-2519
> Project: Apache Drill
> Issue Type: Bug
> Components: Metadata
> Affects Versions: 0.8.0
> Reporter: Daniel Barclay (Drill)
> Assignee: Daniel Barclay (Drill)
>
> 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 or DECIMAL_DIGITS columns for INTERVAL types.
> 1. 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.
> 2. It does not have the fractional seconds precision.
