Which property is used to give an alternative name to a field?
Answers
Answer:
In database management systems, the property used to give an alternative name to a field is called "alias" or "column alias". An alias is essentially a nickname or alternate name for a column or field in a database table.
Explanation:
Using an alias can be beneficial in several ways. It can make the output of queries more readable and understandable for end-users who may not be familiar with the specific column names in a particular database table. An alias can also be used to change the name of a column temporarily, without changing the original name of the field permanently.
Aliases can be specified in SQL queries by using the "AS" keyword followed by the desired alias name. For example, if we wanted to retrieve a list of customer names and addresses from a table called "Customers", we could use the following SQL query:
SELECT CustomerName AS Name, CustomerAddress AS Address
FROM Customers
In this query, the "AS" keyword is used to give the "CustomerName" and "CustomerAddress" fields an alias of "Name" and "Address", respectively. The resulting output of the query will display the data with these aliases instead of the original column names.
