For database testing we use SQL. All manual testers may not use SQL. The people who are working on database testing they use SQL.
For example :

Take ICICI bank as our example. They have their own database which contain customer details, amount details, transaction details and all. If the bank owner came to you and asked to test the ICICI application.
First we need to check how many customers are there in the database. As we all Know, SQL is the language which can retrieve the data from database.
So we need to write query and test.

Select cname from ICICIBANK ---> we get all the customer details here.


Go to application and update any customer mailing address , Again we need to check whether the record is updated or not , for that we again use SQL to check backend data.

Select MAdds from ICICIBANK where cname = ‘ABCD’---> if we find record test case pass or else raise defect :)
