Wrong column type for range partitioning
Production Risk
Low — DDL fails; no data is affected.
Why it happens
- 1A RANGE or LIST partition was defined on a column with a non-integer, non-date data type.
- 2A RANGE COLUMNS partition expression uses an unsupported type.
Fix 1
Use an integer or date column for RANGE partitioning
Why this works
RANGE and LIST partitioning work with integer and date/datetime columns, or RANGE COLUMNS for additional types.
Fix 2
Use RANGE COLUMNS for string or other types
Use RANGE COLUMNS for string or other types
PARTITION BY RANGE COLUMNS (str_col) (PARTITION p0 VALUES LESS THAN (N));
Why this works
RANGE COLUMNS supports string, date, and integer types.
