The DISTINCT operator is used to eliminate duplicates in a result set. When used with the COUNT function, it allows you to count the number of unique values in a column or expression. For example, COUNT(DISTINCT column_name) will return the number of distinct values in that column. This can be useful for analyzing data and identifying patterns.
