Dbmsinfo Function
In OpenROAD, if you use the dbmsinfo function as a statement by itself, the only valid request_name is _bintim:
variable = dbmsinfo('_bintim')
All other values of request_name return blanks unless the function is part of a larger SQL statement. For example, the following statement returns a user name:
select logname = dbmsinfo('username')
However, the following statement returns blanks:
logname = dbmsinfo('username')
