To eliminate duplicates and calculate the sum, you can use SQL’s DISTINCT and SUM functions together.

For example, if there is a table named table1 that has a column named column1, to remove duplicates and sum the values of that column, the following SQL statement can be used:

SELECT DISTINCT column1, SUM(column1) 
FROM table1 
GROUP BY column1;

This way, we can eliminate duplicates and sum the values in column1.
