SQL SELECT DISTINCT

The SQL DISTINCT command is used with SELECT key word to retrieve only distinct or unique data.

In a table, there may be a chance to exist a duplicate value and sometimes we want to retrieve only unique values. In such scenarios, SQL SELECT DISTINCT statement is used.

Note: SQL SELECT UNIQUE and SQL SELECT DISTINCT statements are same.
