You were right. I was wrong. You can do a partial table-name QueryString.
Figure 1. (1) I’m accessing the config table. (2) Enclose the QueryString in single quotes. (3) It works!
If you used the fx to use an expression or property Ignition will sort it out for you. I think you just need it for directly entered strings. It’s a bit confusing when the Named Queries Testing function doesn’t require them.
