TSQL How do you output PRINT in a user defined function?

This is driving me crazy.

I have a function I am trying to debug, but I can’t insert into a table, execute a print statement, or even raise an error from it.

SQL returns the message

Invalid use of a side-effecting operator ‘PRINT’ within a function.

How can I Debug this, I just want to know the value of a variable while it is running?

try:

DECLARE @ExecuteString   varchar(500)
       ,@Yourtext        varchar(500)

@ExecuteString = 'echo  '+@Yourtext+' > yourfile.txt)

exec master..xp_cmdshell @ExecuteString, no_output

use: “>” to create/overwrite file, and “>>” to create/append onto file. you might need to use REPLACE(@Yourtext,'&','^&') to escape the & char
