Question

Which of the following SQL queries would return all of the rows and columns that exist in the employee table?

a. SELECT * FROM employee;
b. SELECT columns FROM employee;
c. SELECT all FROM employee;
d. SELECT rows, columns FROM employee;

Answer 1

The correct SQL query to select all rows and columns from the employee table is 'SELECT * FROM employee;'. This uses the wildcard (*) to indicate all columns from the specified table.

Step-by-step explanation:

The correct SQL query that would return all of the rows and columns from the employee table is a. SELECT * FROM employee; The wildcard (*) is used to select all columns in SQL, and FROM employee specifies that the data should come from the employee table. None of the other options are valid SQL syntax for achieving this objective.

The correct SQL query to return all of the rows and columns in the employee table is option a.

SELECT * FROM employee;

This query uses the asterisk (*) wildcard character to select all columns, and the FROM clause specifies the table name 'employee'.
