[jira] [Updated] (DRILL-2519) INFORMATION_SCHEMA.COLUMNS
missing info
[ https://issues.apache.org/jira/browse/DRILL-2519?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.)
