How to convert column name to upper case

[Markbhai]

Hi Guys,

 Section Access;
LOAD
* INLINE [
ACCESS, USER.EMAIL, SPDI
ADMIN, MARK.ROEBUCK@PROVEPRIVACY.COM, *
USER, ASWATH.P@emvigotech.com, ONE
USER, SATHEESH.M@EMVIGOTECH.COM, *
];
Section Application;

The above section access script in Qlik Sense sheet is working fine, but I want to restrict data based on the 'id' column instead of 'SPDI'. However, my column name is in lowercase. How can I convert it to uppercase in the section access.

@Markbhai use the upper() function, it works like this:

LOAD
  upper(user.email) as USER.EMAIL,

Upper(USER.EMAIL) AS USER.EMAIL,
Upper(id) as ID
INLINE [
ACCESS, USER.EMAIL, ID
ADMIN, MARK.ROEBUCK@*********.COM, *
USER, ASWATH.P@*******.COM, 36
USER, SATHEESH.M@*********.COM, *
