Question

Which command would you run to make a remote table accessible using an alias?

A) CREATE ALIAS
B) ADD ALIAS
C) SET ALIAS
D) ALIAS

Answer 1

To make a remote table accessible using an alias, the correct command is 'CREATE ALIAS'. This command is used to create a temporary name for the table to simplify queries and improve code readability.

Step-by-step explanation:

To make a remote table accessible using an alias, you would run the CREATE ALIAS command. This command is used in SQL and database management for creating a temporary name that will refer to the remote table. The purpose of using an alias is often to simplify complex table names, reduce the amount of typing required for repetitive queries, or to help keep SQL code cleaner and more readable.

Here is a simplified example of how the command might be used:

CREATE ALIAS myLocalAlias FOR 'remoteHost.database.schema.tableName';

Once this command is executed, you can refer to 'remoteHost.database.schema.tableName' as 'myLocalAlias' in your queries, which is particularly helpful in environments with distributed databases.
