Method to Add table as a property to the view

Saikrishna14
Hi

I have used the function dbCreateProp and i could add strings as properties to the views.By using for loop,i have tried to add the individual key value pairs as properties to the view.I am looking for a way to add an entire association table consisting of key value pairs as a property to the view instead of doing each key value pair as a separate property.Could you suggest a way for me to do so? The main reason for avoiding eack key value pair as property is that the number of key-values in the table is very high and there is also a chance that the values corresponding to the key might be altered/tampered.I want the values to be fixed and unchanged.

I should also be able to access the key value pairs of the table (added as a property) later at some point of time.

Regards!

    You can't store data structures such as tables in a cellView property - they are constrained to int, float, string, time, and list types (there are a couple of others, but these are the main types).

    However, you can effectively serialize the table to a list to store it, and vice versa to restore it.

    Assuming you have a table, myTable - you can do:

    dbCreateProp(cvId  "myTable" "ILList" tableToList(myTable))

    or you could just use:

    cvId~>myTable=tableToList(myTable)

    then to convert it back to a table later, you'd do:

    myTable=makeTable('mytab nil) ; default value as second argument - whatever you used when creating it
    append(myTable cvId~>myTable)

    If you append an assoc list onto a table, it adds them as key-value pairs.
