ORA-01873: the leading precision

I am trying to query view but getting "ORA-01873: the leading precision of the interval is too small" error message. Below is the query.

Select * from table order by Col1.

Below is view structure:

Col1    NOT NULL NUMBER
Col2    NOT NULL NVARCHAR2(80)
Col3    NOT NULL NUMBER
Col4    NOT NULL VARCHAR2(10)
Col5        NVARCHAR2(80)
Col6        NVARCHAR2(255)
Col7        NUMBER
Col8    NOT NULL NVARCHAR2(255)
Col9    NOT NULL NVARCHAR2(1)
Col10   NOT NULL NUMBER
Col11       VARCHAR2(19)
Col12       VARCHAR2(19)
Col13       VARCHAR2(19)
Col14       VARCHAR2(19)
Col15       VARCHAR2(19)
Col16       VARCHAR2(19)
Col17       NUMBER
Col18       NVARCHAR2(255)
Col19       NVARCHAR2(80)
Col20   NOT NULL NUMBER

Below is View Definition:

Other queries are running fine like select * from table where Col1 = 123 or select * from table where Col2 = 'xyz' order by Col1 but above query is not working for any col. Please suggest.
