What does 'abc' || 'xyz', when PIPES_AS_CONCAT is enabled, result in?

Solution (By Examveda Team)

This question is about how MySQL handles the double pipe (||) operator when a special setting called PIPES_AS_CONCAT is enabled.

Normally, the double pipe (||) is used for the bitwise OR operation, which combines bits. However, when PIPES_AS_CONCAT is turned on, MySQL treats the double pipe (||) as a string concatenation operator, which means it joins strings together.

In this case, 'abc' || 'xyz' will result in 'abcxyz'.

So the correct answer is Option C: abcxyz.
