To answer this question, we need to understand what DML (Data Manipulation Language) statements are. DML statements are used to modify and manipulate data within a database.
Let's go through each option to determine if it is a DML statement:
Option A) COMMIT - This statement is not a DML statement. COMMIT is used to permanently save any changes made within a transaction.
Option B) MERGE - This statement is a DML statement. MERGE is used to combine data from two tables based on a specified condition.
Option C) UPDATE - This statement is a DML statement. UPDATE is used to modify existing data in a table.
Option D) DELETE - This statement is a DML statement. DELETE is used to remove data from a table.
Option E) CREATE - This statement is not a DML statement. CREATE is used to create new database objects, such as tables, indexes, or views.
Option F) DROP - This statement is not a DML statement. DROP is used to remove existing database objects.
Therefore, the correct answers are options B, C, and D.
