Write SQL to fetch UNIQUE records.
The SELECT DISTINCT statement is used to return only DISTINCT / UNIQUE values
Example
Table: Employee+----+-------+--------+--------------+| Id | Name | Salary | DepartmentId |+----+-------+--------+--------------+| 1 | Ram | 85000 | 1 || 2 | Henry | 80000 | 2 || 3 | Sam | 60000 | 2 || 4 | Shyam | 60000 | 1 || 5 | Geeta | 90000 | 1 || 6 | Sheet | 90000 | 1 || 7 | Leela | 80000 | 1 || 8 | Geeta | 70000 | 1 |+----+-------+--------+--------------+
Approach: Select unique employee
Mysql:
SELECT DISTINCT NAME FROM EMPLOYEE
Oracle:
SELECT DISTINCT NAME FROM EMPLOYEE
Result:
+--------+| NAME |+--------+| Ram || Henry || Sam || Shyam || Geeta || Sheeta || Leela |+--------+
