After successfully deploying a container using gcloud builds submit --tag gcr.io/projectname/testserver and then attempting to run gcloud run deploy --image gcr.io/projectname/testserver --platform managed I see this error:

I am quite new to writing functions and am working a generic function that is to be applied to several, but not all, rows in a data frame. The function is supposed to conditionally transform the values of these specified rows.

Example data: df <- data.frame("Var1" = c(0:5), "Var2" = c(-5:0), "Var3" = c(0,0,0,0,0,0)

I am in the process of designing a workflow to export data from an Oracle database to another system. Unfortunately, I've hit a tricky problem. The destination system uses an XML-based import and any data input must be in a very particular format. Certain fields are not nillable and must have data in them even if it is just the word "none". The reporting tool I'm using (eVisions Argos) can handle this by using If statements to conditionally print out the word none if a field is null.

Here's the problem. Some of the data in a few columns in the originating database is inconsistent. Most of the fields in question aren't null, but contain two spaces (not sure why - I'm not the DBA). The exception is a handful of fields which actually are null and some which have data in them.

Is there a way to structure my query so as to select the data in a field if it is there, but otherwise put a null value in? I tried this (the full query is excluded as it is a bit lengthy):

So I've been designing in XML in Android Studio a standard log in page - with an image covering about half of the screen, and then the edit text fields occupying the bottom half, asking for the log in details. My problem is that when I tap on the edit text fields on smaller mobile displays, it will only snap to and show the field I have selected, when I think it's far better if it were to automatically snap to show all fields and the 'Next' button at once.

What I WANT to see when I click on 'UserID' field

How do I achieve this result?
