FullName
First name is Stuart
First name is William
First name is Doris
Likewise, you can assign more than one alias in the SELECT statement, as in the following code:
SELECT LastName AS Surname, FirstName AS ChristianName
FROM MemberDetails;
The results of the preceding SELECT statement are as follows:
Surname ChristianName
Smith Katie
Simons Susie
Jackson John
Gee Steve
Jones John
Jones Jenny
Johnson Jack
Botts Seymour
Hills Jamie
Dales Stuart
Doors William
Night Doris
Finally, if you want to use an alias that contains spaces or any other characters normally not permitted
for column names or aliases, then you must enclose the alias name inside square brackets, as shown in
the following statement:
SELECT LastName AS Surname, FirstName AS [Christian Name]
FROM MemberDetails;
Using this SQL, the alias Christian Name has a space, so it’s enclosed inside the square brackets.
Square brackets allow you to use names for columns or aliases that contain characters not normally considered
legal. For example, you would receive an error if you tried to use the alias One***Two, as in the
following query:
SELECT DateOfBirth AS One***Two FROM MemberDetails;
