when I execute the attached script for my table and for all columns, I am getting the following error:

ErrorNumbe ErrorMessage

207 Invalid column name 'NLL'.

Here are my values:

DECLARE @TABLE_SCHEMA NVARCHAR(128) = 'dbo' -- Your schema here

DECLARE @TABLE_NAME NVARCHAR(128) = 'Customer' -- Your table here

DECLARE @ColumnListIN NVARCHAR(4000) = '' -- Enter a comma-separated list of specific columns

-- to profile, or leave blank for all

Please help me on this error.
