Question
The Distinct Keyword In Sql Is Used To
Solution
The DISTINCT keyword in SQL is used to return only distinct (different) values. In a table, a column may contain many duplicate values; and sometimes you only want to list the different (distinct) values.
Here are the steps to use the DISTINCT keyword in SQL:
-
Start by writing the SELECT statement:
SELECT -
After the SELECT statement, write DISTINCT:
SELECT DISTINCT -
Then write the name of the column from which you want to select distinct values:
SELECT DISTINCT column_name -
After that, specify the table where this column exists:
SELECT DISTINCT column_name FROM table_name;
So, the complete SQL statement will look like this: SELECT DISTINCT column_name FROM table_name;
This SQL statement will return all distinct values from the column_name in the table_name.
