I am selecting a random selection of a table and want to mark the selected columns. I have an 'exported' column which is binary and is set 0 by default. When selecting it I want it to become 1. I thought of combining a SELECT and INSERT statement like:

currently, I'm working on a school project where we have to program an app. We need to get the latitude and Longitude from an address. I found the Google API and the HERE API, but for the Google API, you need to give credit card information so we won't use that.

I already looked around, but I couldn't find anything that could help me in my situation.

My problem is to read the data from the responseJson. I get this error.

This is the code snippet that gets called

Must I use a loop to clear some data in an associative array, or is there a faster & better option?

currently I'm using:

I'm trying to access data from an array while in a loop.

this command works fine..

I see a lot of topics about this but it seems that all of them access KEYCLOAK with the same URL. Explanation. I try to set up un frontend+microservice secured by KC achitecture. See the drawing :

Everything work well if keycloak (kc) is seen by everybody with the same url, that is for JS :

I'm trying to save the auto incremented ID that'll be created in the table 'accounts' when a new user filled out the registration form in the second table 'userdaten'.

The code saves the data in both tables like it should, but I still need to get the auto incremented 'id' from table 'accounts' into my table 'userdaten'

I am facing a null object error which I cannot solve. My App compiles just fine but however when I use the function of "rating food" the App crashes and is showing the Error I have linked. I cannot really figure out why it should be a null object since the "Vorname" gets saved when the user registers. Is maybe the way I want to identify the "Vorname" wrong? If you have any Ideas what I should change please let me know. Thanks and have a good day!

If you need any more information please let me know.

Hey im struggling with a mysql query.

I have to select PNr, HName, arrivalDate from pairs of employees which are in the same hotel with equal arrival date. These pairs should be sorted ASCENDING.

Any ideas? Im new to complex mysql queries and can't figure it out.

I'm still working on my Login App. At the moment the user can register, sign in and update profile information. The data is stored in firebase realtime database and the athentificacion also works via firebase. I wanted to add a "Delete Profile" button, so the user information is deleted from firebase. I figuered out how to delete the user from the autentification process. Now I tried to call the remove() function to the Uid, so now the data gets deleted in the real time database but is still in the Firebase authentification and the app crashes if you delete the userdata. So only one of the deleting processes works... either the autentification or deleting the user from the database. Maybe the problem is about structure and child/parent relation in the realtimedatabase? My suggestion is that the order in onClickListener() could be incorrect? How can i delete both of it at once and get this process working? Thx in advance :)
