To retrieve only unique values from a column in SQL, you would use the ___________ keyword.

  • DISTINCT
  • SELECT DISTINCT
  • UNIQUE
  • UNIQUE VALUES
The SELECT DISTINCT keyword is used in SQL to retrieve only unique values from a specified column in a table. When you use SELECT DISTINCT, the query results will eliminate duplicate values, presenting only distinct values in the result set. This is particularly useful when you want to analyze or display unique entries without redundancy. It's important to note that SELECT DISTINCT operates on a single column or a combination of columns, and it can be combined with other clauses like WHERE for more specific filtering. Understanding how to use SELECT DISTINCT helps in generating accurate and concise reports or data analysis results.
