ORA-14752: Interval expression is not a constant of the correct type
Cause:
You attempted to use either a nonconstant interval or an interval whose data type does not correspond to the partitioning column
Action:
Use only constant expressions for the interval. If the data type of partitioning column is numeric, the interval must be a numeric constant. If the data type is of type date/time, the interval must be a constant of interval type
