I am trying to use a expression tag with following expression and I see “Unknown function” error in diagnostic.

executeScalarQuery(“exec [SF].[uspGetSFOutputPercent] @Workstation=’{[.]MachineName}’”,“DBConnection”)

We are currently aware of a number of Expression functions that aren’t working correctly. This includes all of the **Database** and **Store & Forward** functions.

@ggross Has this bug been resolved in 8.0.1? I’m getting “Error\_Configuration” in the Quality field when I try this with an expression tag. The query I’m using works perfectly in the Database Query Browser.

It seems like this is still a problem in 8.04x.

At least executeScalarQuery() is not working for me
