What is abc in the following MySQL statement?

DECLARE abc HANDLER FOR def ghi;

Solution (By Examveda Team)

This MySQL statement is used to declare a handler. Handlers are used to handle specific events that occur during the execution of a stored procedure or function.

The `DECLARE` keyword tells MySQL that you are defining a handler.

The `abc` in the statement is the name of the handler. It's like giving the handler a unique identifier so you can refer to it later.

Here's a breakdown of the other parts of the statement:

* `HANDLER FOR`: This part specifies the event that the handler will respond to. In this case, it's `def ghi`.

Let's look at the options:

* Option A: action - This is partially correct. Handlers define actions, but `abc` represents the handler's name, not the action itself.
* Option B: condition value - This is not correct. `abc` is not a condition value.
* Option C: statement - This is the closest answer. `abc` is a handler name, which is part of a statement that declares a handler.
* Option D: null - This is incorrect. `abc` has a specific meaning and purpose.

Therefore, the best answer is Option C: statement.
