    181:       def cast_numeric(sql_type = nil)
    182:         cast(sql_type || Integer).sql_number
    183:       end

cast_string(sql_type = nil)

Cast the reciever to the given SQL type (or the database‘s default string type if none given), and return the result as a StringExpression, so you can use + directly on the result for SQL string concatenation.
