I’m converting a 7.9 project to 8.0, and I’m confused on the UDTs. In 7.9 I had a UDT tag that had a query binding that used another tag in the same UDT in the where clause. v8 does not have it available to select a tag from the UDT in a query binding. Am I missing something, or is there another way to do this?  
v7.9 on left, v8 on right

This is a missing piece of UI (that we’re aware of, and planning to/already have fixed). The syntax from 7.9 should still work…there’s just no easy way to make the selection in 8.0.

Is there a link to the 7.9 syntax?

`where user = '{[.]uname}'`

uname is a tag in my udt, just use the `[.]` in front of the tag name you want to reference

The 7.9 manual is also still online: [https://docs.inductiveautomation.com/display/DOC79/Data+Type+Parameters+in+Expressions](https://docs.inductiveautomation.com/display/DOC79/Data+Type+Parameters+in+Expressions)
