SQL CREATE Table Name with System defined variable

Hello all,

I am still learning CACHE and have below question.

In one of my ZEN method i am creating a table using

&sql(CREATE TABLE xxxxx(TNAMESPACE CHAR(100),TINTERFACE CHAR(100)))

Does any one knows how to concatenate a $USERNAME or any  content of a variable to the name of table ?

&sql(CREATE TABLE xxxxx_$USERNAME(TNAMESPACE CHAR(100),TINTERFACE CHAR(100))) is not WORKING.

Thanks,

Jimmy Christian.
