    2. COhello Abdel, I checked that code too but currently I am not getting any error.. I was having error of 'me.store.getRootNode is not a function', which I solved from that thread. Currently I have no error. No matter what I am doing nothing is changing actually. I also tried to use ajax proxy as given in example of extjs. But it also loads empty tree. Do you have any other ideas? thanks

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).
