Question

If the results of a SELECT statement include more than one column of data, the column names must be separated in the SELECT clause by which of the following symbols?

A) ,
B) " "
C) ' '
D) *

Answer 1

In a SELECT statement, multiple column names are separated by a comma (,). This is standard SQL syntax to denote different fields to be selected from a database.

Step-by-step explanation:

If the results of a SELECT statement include more than one column of data, the column names must be separated in the SELECT clause by a comma (,). This punctuation mark serves as a delimiter that allows the database system to recognize each column as a separate entity. When writing a query with multiple columns, it is important to ensure that each column name is followed by a comma, except for the last column in the list.
