    1. COI have a couple of suggestions for you. First, don't forget to call `[super viewDidLoad]`, and in your `numberOfRowsInSection` method you are returning `totalData count` instead of `TableVideoIDArray count`.

    2. COin my actual code [super viewDidLoad] is there,my mistake for not mentioning here and in numberOfRowsInSection i removed totalData with TableVideoIDArray,but same result is happenning

    3. COIf what you pasted isn't your actual code, how do you expect anyone to find the problem? :) You should post your full solution. If you have to rename variables/methods for security purposes, that's OK.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
