All alphabetical characters in the input value are converted to uppercase in the output value.

Input can be a column reference or a string literal.

Basic Usage

Column reference example:

derive type:single value:UPPER(MyName)

Output: All of the string values in the MyName column value are written to the new column in UPPER.

String literal example:

derive type:single value:UPPER('Hello, World')

Output: The string HELLO, WORLD is written to the new column.

Example - uppercase, lowercase, propercase functions

This example demonstrates functions that can be used to change the case of String values.

Functions:

Item	Description
UPPER Function	All alphabetical characters in the input value are converted to uppercase in the output value.
LOWER Function	All alphabetical characters in the input value are converted to lowercase in the output value.
PROPER Function	Converts an input string to propercase. Input can be a column reference or a string literal.

Source:

In the following example, you can see a number of input values in the leftmost column. The output columns are blank.

input	uppercase	lowercase	propercase
AbCdEfGh IjKlMnO
go West, young man!
Oh, ($%(&! That HURT!
A11 w0rk and n0 0play makes Jack a dull boy.

Transformation:

To generate uppercase, lowercase, and propercase values in the output columns, use the following transforms:

Transformation Name	`Edit column with formula`
Parameter: Columns	`uppercase`
Parameter: Formula	`UPPER(input)`

Transformation Name	`Edit column with formula`
Parameter: Columns	`lowercase`
Parameter: Formula	`LOWER(input)`

Transformation Name	`Edit column with formula`
Parameter: Columns	`propercase`
Parameter: Formula	`PROPER(input)`

Results:

input	uppercase	lowercase	propercase
AbCdEfGh IjKlMnO	ABCDEFGH IJKLMNO	abcdefgh ijklmno	Abcdefgh Ijklmno
go West, young man!	GO WEST, YOUNG MAN!	go west, young man!	Go West, Young Man!
Oh, ($%(&! That HURT!	OH, ($%(&! THAT HURT!	oh, ($%(&! that hurt!	Oh, ($%(&! That Hurt!
A11 w0rk and n0 0play makes Jack a dull boy.	A11 W0RK AND N0 0PLAY MAKES JACK A DULL BOY.	a11 w0rk and n0 0play makes jack a dull boy.	A11 W0rk And N0 0play Makes Jack A Dull Boy.
