    <p>I always use this code to open a sqlite db in my iPhone application, but now with iOS6 this code doesn't work. The function: sqlite3_prepare_v2 fails but I don't understand why!</p> <p>I also don't understand why if I try to change the name: "gamer.sqlite" of sqlite db with another name of an not existent file, the function: 'sqlite3_open' return again SQLITE_OK value.</p> <p>This is my code:</p> <pre><code>-(NSMutableArray*)view_table { const char *sql; NSMutableArray *content=[[NSMutableArray alloc] initWithObjects:nil]; [self msgbox:@"eseguo"]; /*elementi da visualizzare nella tabella*/ if(sqlite3_open([databasePath UTF8String],&amp;database)==SQLITE_OK) { [self msgbox:@"opened"]; sql = "SELECT * FROM list_gamer"; if (sqlite3_prepare_v2(database,sql, -1, &amp;selectstmt, NULL) == SQLITE_OK) { [self msgbox:@"query eseguita"]; while(sqlite3_step(selectstmt) == SQLITE_ROW) { [content addObject:[NSString stringWithFormat:@"%s",sqlite3_column_text(selectstmt,0)]]; } } } return content; } - (void)viewDidLoad{ NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDir = [documentPaths objectAtIndex:0]; databasePath = [[documentsDir stringByAppendingPathComponent:@"gamer.sqlite"] copy]; if(![[NSFileManager defaultManager] fileExistsAtPath:databasePath]) { NSFileManager *fileManager = [NSFileManager defaultManager]; int success = [fileManager fileExistsAtPath:databasePath]; if(success) { [fileManager removeItemAtPath:databasePath error:nil]; return; } NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"gamer.sqlite"]; // Copy the database from the package to the users filesystem [fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:nil]; documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDir = [documentPaths objectAtIndex:0]; } [super viewDidLoad]; } - (void)didReceiveMemoryWarning{ [super didReceiveMemoryWarning]; } -(IBAction)start_game:(id)sender{ self.view=frmgame; [self view_table]; } </code></pre>

    1. COYou need to get the error from the database. Add an `else` that handles the failure of the prepare statement. Use `sqlite3_errmsg` to get the error, then log the error message.

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).
