Question
Which of the following are DML statements?
Select one or more:
- a.
SELECT - b.
CREATE - c.
TRUNCATE - d.
INSERT
Solution
The DML (Data Manipulation Language) statements from the options provided are:
a. SELECT d. INSERT
Explanation:
DML (Data Manipulation Language) includes SQL commands that are used to manipulate data present in the database. DML statements are used for adding new rows, deleting existing rows, and modifying or updating existing rows in a database table.
The SELECT statement is used to select data from a database. The data returned is stored in a result table, called the result-set.
The INSERT statement is used to insert new data into a database.
On the other hand, CREATE and TRUNCATE are DDL (Data Definition Language) statements, not DML. CREATE is used to create the database or its objects (like table, index, function, views, store procedure, etc.). TRUNCATE is used to delete all the rows from the table and free the space containing the table.
