Daniel Barclay (Drill) updated DRILL-3216:
------------------------------------------
Description:
[Editing in progress]
Change logical null from {{-1}} to actual {{NULL}}:
- Change column {{CHARACTER_MAXIMUM_LENGTH}}.
- Change column {{NUMERIC_PRECISION}}.
- Change column {{NUMERIC_PRECISION_RADIX}}.
- Change column {{NUMERIC_SCALE}}.
Change column {{DATA_TYPE}} from short names (e.g., "CHAR") to specified names
(e.g., "CHARACTER").
Change column {{ORDINAL_POSITION}} from zero-based to one-based.
Move {{CHAR}} length from {{NUMERIC_PRECISION}} to {{CHARACTER_MAXIMUM_LENGTH}}
(same as {{VARCHAR}} length):
- Change column {{NUMERIC_PRECISION}} from length to logical null for CHAR.
- Change column {{CHARACTER_MAXIMUM_LENGTH}} from logical null to length for
CHAR.
Move {{BINARY}} and {{VARBINARY}} length from {{NUMERIC_PRECISION}} to
{{CHARACTER_MAXIMUM_LENGTH}} (same as CHAR and VARCHAR length):
- Change column {{NUMERIC_PRECISION}} from length to logical null for BINARY
and VARBINARY.
- Change column {{CHARACTER_MAXIMUM_LENGTH}} from logical null to length for
BINARY and VARBINARY.
Fix data type names "INTERVAL_DAY_TIME" and "INTERVAL_YEAR_MONTH" to "INTERVAL":
- Change column {{DATA_TYPE}} to list "INTERVAL" for interval types.
- Add column {{INTERVAL_TYPE}}.
To correct ordinal position of some existing columns:
- Add column {{COLUMN_DEFAULT}}.
- Add column {{CHARACTER_OCTET_LENGTH}}.
- Reorder column {{NUMERIC_PRECISION}}.
Move date/time and interval precisions from {{NUMERIC_PRECISION}} to
{{DATETIME_PRECISION}} and {{INTERVAL_PRECISION}}:
- Change column {{NUMERIC_PRECISION}} to logically null for date/time and
interval types.
- Add column {{DATETIME_PRECISION}}.
- Add column {{INTERVAL_PRECISION}}.
Implement {{NUMERIC_PRECISION_RADIX}}:
- Change column {{NUMERIC_PRECISION_RADIX}} from always logically null to
appropriate values (2, 10, NULL).
Add missing numeric precision and scale values (for non-DECIMAL types):
- Change NUMERIC_SCALE from logical null to zero for integer types.
- Change NUMERIC_PRECISION from logical null to precision for non-DECIMAL
numeric types.
