How to exclude a minimum value while calculating sum in a SQL query. The values are grouped by an ID column. ( Decimal column)

EX. If there are 3 values 50,100,200
While calculating sum we should exclude the lowest one i.e 50 and result should be 300..
If there are duplicates,
50,50, 100,200 ...then the count should be 350( excluding the latest duplicate value)

How do u write sql query for it.

Code:

SELECT COL1,                                       
       (SUM(VAL_COL) - MIN(VAL_COL))   
FROM tabname
GROUP BY COL1;

It should have been something like below.

SQL Query to substract the lowest value in the column and get the SUM total
