To answer this question, you need to understand the concept of Data Manipulation Language (DML) statements. DML statements are used to manipulate data stored in a database. Let's go through each option to understand which ones are DML statements:
Option A) COMMIT - This option is not a DML statement. COMMIT is used to save all the changes made in a transaction to the database.
Option B) MERGE - This option is a DML statement. The MERGE statement allows you to update or insert data into a target table based on the results of a join with a source table.
Option C) UPDATE - This option is a DML statement. The UPDATE statement is used to modify existing data in a table.
Option D) DELETE - This option is a DML statement. The DELETE statement is used to remove rows from a table.
Option E) CREATE - This option is not a DML statement. CREATE is a Data Definition Language (DDL) statement used to create database objects such as tables, views, and indexes.
Option F) DROP - This option is not a DML statement. DROP is a DDL statement used to remove database objects.
The correct answers are B, C, and D. These options are DML statements because they are used to manipulate data stored in a database.
