    <p>Something really weird has happened to my source code. The application always built successfully, and I always used to be able to launch the application. However recently, the app crashes when I launch it and return the following error in the console:</p> <pre><code>2009-07-23 20:30:06.390 App[15652:20b] Database Successfully Opened :) 2009-07-23 20:30:06.393 App[15652:20b] *** Assertion failure in -[AppDelegate initializeTableData], /Users/me/Desktop/App/Classes/AppDelegate.m:39 2009-07-23 20:30:06.394 App[15652:20b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error preparing statement' 2009-07-23 20:30:06.394 App[15652:20b] Stack: ( </code></pre> <p>I don't understand. The app would always launch successfully with no error. But now I get this error. I had backed up my source code along the way and now when I build those older versions, I get the same error. How is this even possible. Can code go bad? If I was able to successfully launch an application before and I go back today and recompile it and it returns an error...THE SAME PIECE OF CODE?</p> <p>The error seems to point to this piece of code in my AppDelegate file:</p> <pre><code>enter code -(void)initializeTableData { entries = [[NSMutableArray alloc] init]; sqlite3 *db = [AppDelegate getNewDBConnection]; sqlite3_stmt *statement = nil; const char *sql = "select * from dict"; if(sqlite3_prepare_v2(db, sql, -1, &amp;statement, NULL) != SQLITE_OK) NSAssert1(0,@"Error preparing statement", sqlite3_errmsg(db)); else { while(sqlite3_step(statement) == SQLITE_ROW) { // Read the data from the result row NSString *aGurmukhi = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]; NSString *aShahmukhi = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 1)]; NSString *aPOS = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 2)]; NSString *aEnglish = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 3)]; // Create a new animal object with the data from the database Entry *entry = [[Entry alloc] initWithName:aGurmukhi shahmukhi:aShahmukhi pos:aPOS english:aEnglish]; // Add the animal object to the animals Array [entries addObject:entry]; [entry release]; } } //release the resources sqlite3_finalize(statement); </code></pre> <p>}</p> <pre><code>+(sqlite3 *) getNewDBConnection{ sqlite3 *newDBconnection; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"pedict.db"]; // Open the database. The database was prepared outside the application. if (sqlite3_open([path UTF8String], &amp;newDBconnection) == SQLITE_OK) { NSLog(@"Database Successfully Opened :)"); } else { NSLog(@"Error in opening database :("); } return newDBconnection; </code></pre> <p>}</p> <p>It seems to be a problem with the database connection, but I'm still confused over how this is all possible. Please help...I've already waisted six hours debugging, with little success</p>

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).
