Question
Which keyword is used to display uniquely data from any specific column ?
Solution
The keyword used to display unique data from any specific column in SQL (Structured Query Language) is "DISTINCT".
Here is a step by step guide on how to use it:
-
Start with the SELECT statement: This is used to select data from a database.
-
Use the DISTINCT keyword: This is used to return only distinct (unique) values.
-
Specify the column name: This is the column from which you want to retrieve the data.
For example, if you have a table named "Students" and you want to find all unique values in the "Course" column, you would write:
SELECT DISTINCT Course FROM Students;
This SQL statement selects unique "Course" values from the "Students" table.
