    <p>I'm not 100% sure, because there's no error detail provided, but it looks like <code>addStatement</code> is not being initialized. Does Objective-C initialize all pointers to 0 when they're allocated on the stack? I know that in Linux that would not work.</p> <p>Perhaps try this: <code>sqlite3_stmt *addStatement = nil;</code></p> <p>I have to wonder, why are you even checking <code>addStatement == nil</code>? There's no reason to check it, since you must initialize it in every case.</p> <p>In short, re-write like so:</p> <pre><code>(BOOL) addticket { NSString *event=@"max"; NSString *venue=@"tvm"; sqlite3 *database; databaseName = @"smbhDB.sql"; sqlite3_stmt *addStatement ; NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDir = [documentPaths objectAtIndex:0]; const char *sql ="insert into tickets (venue, event,) Values (?,?)"; databasePath = [documentsDir stringByAppendingPathComponent:databaseName]; /* this is no longer conditional code */ if(sqlite3_prepare_v2(database, sql, -1, &amp;addStatement, NULL) != SQLITE_OK) NSAssert1(0, @"444 Error while creating add statement. '%s'", sqlite3_errmsg(database)); sqlite3_bind_text(addStatement, 1, [venue UTF8String], -1, SQLITE_TRANSIENT); sqlite3_bind_text(addStatement, 2, [event UTF8String], -1, SQLITE_TRANSIENT); if(SQLITE_DONE != sqlite3_step(addStatement)) NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database)); sqlite3_reset(addStatement); ... </code></pre>

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.

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