1. What is the problem? Be very detailed.
I am trying to get this data (Registered Hospitals) dynamically in my main form as drop down values. I want to use reference the dropdown values from another table or MySQL table instead of the csv file.
Should I create a separate table for Registered Hospitals? How can I link the table into my main form as drop down values?
2. What app or server are you using and on what device and operating system? Include version numbers.
I setup ODK-X Sync Endpoint with AWS
Windows
If you want to use another table instead of the csv file, you will need to create that other separate table for hospitals just like any other table/form.
Once you do that, you can then used the linked_table functionality described on this page: Using ODK-X XLSX Converter — ODK-X Docs
to make a query from your main form that refers to the hospitals form - a bit like a query for csvs but for a table
You can then use a select_one prompt in your main table/form to, for example, select a hospital that is in the hospital where a person is visiting. There is an example of this for a household survey where you enter data in a linked table on each member, and then go back to the household form to use that list to answer a question on the household head: Using ODK-X XLSX Converter — ODK-X Docs
