An example of an AI chatbot conversation about set operations in databases.
What are set operations in databases?
Set operations in databases refer to operations that manipulate sets of data, such as union, intersection, and difference.
Can you explain the union operation?
Sure! The union operation combines the results of two queries, returning all unique records from both.
What about the intersection?
The intersection operation returns only the records that are present in both sets, eliminating duplicates.
How does the difference operation work?
The difference operation returns records from one set that are not present in the other, effectively subtracting one set from another.
