Input can be a column reference or a string literal.

derive type:single value:LOWER(MyName)

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

Example - uppercase, lowercase, propercase functions


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

AbCdEfGh IjKlMnO

Oh, *(*$%(&! That HURT!
A11 w0rk and n0 0play makes Jack a dull boy.


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

set col:uppercase value:UPPER(input)

set col:lowercase value:LOWER(input)

set col:propercase value:PROPER(input)
