Oracle DB Column in table with default for the user

I have a column that I want defaulted to the current user doing the Insert into the table? I have SYSTIMESTAMP as my default for the CREATE_DATE column but now I want the CREATE_BY column defaulted to SYSUSER(I think that is for SQL Server)

Check any Oracle SQL reference for the syntax, but you're simply passing the parameter when you define or modify the column, such as column name default sysuser.

Check out USER:
create table tab1(col1 varchar2(20) default user, col2 char(1));

If you ever want anything else, you might need to step up to SYS_CONTEXT.  There are a LOT of things you get pull with that:
