UPPER

Returns a character expression with lowercase character data converted to uppercase.

Syntax

UPPER ( character_expression )

Arguments

character_expression

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

Return Types

Remarks

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

Examples

This example uses the UPPER and RTRIM functions to return the trimmed, uppercase author's last name concatenated with the author's first name.

USE pubs
GO
SELECT UPPER(RTRIM(au_lname)) + ', ' + au_fname AS Name
FROM authors
ORDER BY au_lname
GO
