Data Field Names that Start with a Number
There are not many rules to observe about naming data fields for ThingWorx Analytics. However, unless some specific rules are followed, certain query services have trouble handling field names where the first character is a number.
To avoid such problems, observe the following rules if the first character in a field name is a number:
1. The field name must include three or more characters in total.
2. The second character in the field name can be a letter, an underscore, or a hashtag. It cannot be a number.
3. The third character can be a letter, a number, an underscore, or a hashtag.
4. Subsequent characters can include anything.
