Combine the Values - clarencemartin - 02-24-2023

This is a really cool action.
I assume that this is where one would create comma-delimited links to database records in a possible to a one-to-many and many-to-many relationship with records.
An example, please.

Hi Clarence,

You can use this action to take the value of one variable or typed input and the value of a second variable or typed input to put them together to be stored in a variable.

Eg:

Var1 = Apple
Var2= Orange
Separator = , (comma)

The result is stored in an existing or new variable = Apple,Orange

This action is most useful for displaying content that should be put together. You could also use this to merge two values to be stored in a database.

Once we add the cdb_merge() function as an action, I would consider using that since the merge to data can be done in a single call.

The cdb_merge() function will be handy to create 1-to-many links in the data, then?

Are you looking for database joins?
We have some ideas about this down the road.

In our apps, we currently store the recordIDs as foreign keys.

Eg:

Table - Employees with the keys: firstName, lastName, tasks
Table - Tasks


In Employees we have a list of names. Each record may look like this:
firstName: Dan
lastName: Jones
tasks: recordID45, recordID77


In our Tasks tabler we have many records describing potential tasks for employees. RecordID45 and recordID77 are relevant to our example employee.
recordID45: Take out the trash
recordID77: Power the cold fusion system

Thus, our Employee record will have: RecordID45,recordID77 in the tasks key for table Employees.

When we do a read on the employee record, we will do a secondary read on records recordID45 and recordID77 to get the tasks and display this nicely in a form or some other view.

Sorry, I went offline. I'll explore your example today.
