How to get unique value in oracle?

@cali_green 

To get unique values in Oracle, you can use the DISTINCT keyword in your SQL query. Here is an example:

1
2

SELECT DISTINCT column_name
FROM table_name;

This will return only the unique values of the specified column in the table. Alternatively, you can use the GROUP BY clause to group the data by a specific column and then use aggregate functions like COUNT() to count the distinct values.

1
2
3

SELECT column_name, COUNT(*)
FROM table_name
GROUP BY column_name;

This will return the distinct values in the specified column along with the count of occurrences for each unique value.
