How to compare the data from same table in oracle?

@dalton_moen 

To compare the data from the same table in Oracle, you can use a self-join query. Here is an example of comparing data from the same table in Oracle:

1
2
3
4

SELECT t1.column1, t1.column2, t2.column1, t2.column2
FROM your_table_name t1, your_table_name t2
WHERE t1.column1 = t2.column1
AND t1.column2 <> t2.column2;

In this query, we are selecting data from the same table twice using aliases t1 and t2. We are then comparing the values of column1 and column2 between the two instances of the table to identify any differences. You can adjust the columns and conditions in the WHERE clause based on your specific requirements for comparing the data.
