Question
Let a table Student has 10 records and Stream has 3 records, then how many rows we will get by using below query:Select * from Student, StreamA3B10C13D30
Solution
The answer is D30. This is because the query is performing a Cartesian product (also known as a cross join) between the Student and Stream tables. In a Cartesian product, each row from the first table is combined with each row from the second table. So if the first table has 10 records and the second table has 3 records, the result will be 10*3 = 30 records.
