Sorry, let me go a bit further. Is there a way to iterate through the SQL Tags? Talking about an Internal Provider.

There is a module KyleChase wrote that iterates through SQLTags. Here is a link to the module:

[http://inductiveautomation.com/forum/viewtopic.php?f=88&t=7815](http://inductiveautomation.com/forum/viewtopic.php?f=88&t=7815)

It is called system.tag.getChildren(“path/to/folder”)
