INFORMIX-SQL or any other SQL-based DB:

Suppose I have an app where depending on the value of some columns, example:

company.code  char(3) {abc}
company.brach char(2) {01}

Can I construct table name "abc01" for inclusion in SELECT * FROM abc01; ? In other words, a variable table name.. same question applies for column names.
