Body
Under the covers sqlite-net does some amazing things in an attempt to manage queries and connections for you. For example, the line <pre><code>var data = db.Table<tablename>().Where(...) </code></pre> Does not actually establish a connection or execute anything against the database. Instead, it creates an instance of a class called TableQuery which is enumerable. When you call <pre><code>int iDataCount = data.Count(); </code></pre> TableQuery actually executes <pre><code>GenerateCommand("count(*)").ExecuteScalar<int>(); </code></pre> When you call <pre><code>Elements = data.ElementAt(i); </code></pre> TableQuery actually calls <pre><code>return Skip(index).Take(1).First(); </code></pre> Take(1).First() eventually calls GetEnumerator, which compiles a SQLite command, executes it with TOP 1, and serializes the result back into your data class. So, basically, every time you call data.ElementAt you are executing another query. This is different from standard .NET enumerations where you are just accessing an element in a collection or array. I believe this is the root of your problem. I would recommend that instead of getting the count and using a for(i, ...) loop, you simply do foreach (tablename tn in data). This will cause all records to be fetched at once instead of record by record in the loop. That alone may be enough to close the query and allow you to delete the table during the loop. If not, I recommend you create a collection and add each SID to the collection during the loop. Then, after the loop go back and remove the sids in another pass. Worst case scenario, you could close the connection between loops. Hope that helps.

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.
