Question

What keywords can Trigger code contain?

A. DML keywords, such as INSERT, UPDATE, and DELETE.
B. DDL keywords, such as CREATE, DROP, and ALTER.
C. Control flow keywords, such as IF, ELSE, and WHILE.
D. All of the above.

Answer 1

In trigger code, the keywords that are typically involved are DML keywords like INSERT, UPDATE, and DELETE, and control flow keywords such as IF, ELSE, and WHILE. DDL keywords like CREATE, DROP, and ALTER are not generally used in trigger code.

Step-by-step explanation:

Keywords that can trigger code, specifically in the context of database triggers, can vary depending on the functions and operations they are designed to perform. The keywords that can be included in trigger code encompass:

• DML keywords, such as INSERT, UPDATE, and DELETE.
• Control flow keywords, such as IF, ELSE, and WHILE.
• DML keywords are used within triggers to define the type of data manipulation that will cause the trigger to execute.
• Control flow keywords help determine the logic flow within the triggers; for instance, they can dictate what action to take when certain conditions are met.
• DDL keywords, such as CREATE, DROP, and ALTER, are generally not used in triggers because triggers are meant to respond to DML events, not schema changes.

Therefore, the correct answer to the question of what keywords can trigger code contain is A. DML keywords, such as INSERT, UPDATE, and DELETE, and C. Control flow keywords, such as IF, ELSE, and WHILE. DDL keywords do not typically trigger code in traditional database systems.
