    CAN ANYONE TELL ME WHERE IM WRONG: select case when ((a+b > c) OR (a+c > b) OR (b+c > a)) then ( select CASE when (a=b AND b=c) then 'Equilateral' when ((a=b AND a!=c) OR (b=c AND a!=c) OR (a=c AND b!=c)) then 'Isosceles' when (a!=b AND a!=c AND b!=c) then 'Scalene' end ) else 'Not A Triangle'

    end from TRIANGLES;

    Can't understand why this query is wrong? Can anyone explain please?

    select case
           when (A+B)>C or (B+C)>A or (C+A)>B then
                                                    case when A=B and B=C then 'Equilateral'
                                                         when (A=B and B!=C) OR (B=C and C!=A) OR (A=C and B!=A) THEN 'Isosceles'                                                                when (A!=B and B!=C) then 'Scalene'
           else 'Not A Triangle'
           end as triangle_type
from TRIANGLES;
