UPPER ( character_expression )


Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data.

character_expression must be of a data type that is implicitly convertible to varchar. Otherwise, use CAST to explicitly convert character_expression.

varchar or nvarchar

The following example uses the UPPER and RTRIM functions to return the last name of people in the Person table in the AdventureWorks2012 database so that it is uppercase, trimmed, and concatenated with the first name.

SELECT UPPER(RTRIM(LastName)) + ', ' + FirstName AS Name
FROM Person.Person
ORDER BY LastName;
