    <p>I did this but it still doesn't work, as in nothing shows up in the Console.</p> <pre> #import "RootViewController.h" #import "FMDatabase.h" @implementation RootViewController - (void)viewDidLoad { [super viewDidLoad]; NSString *dbname = @"name.sqlite"; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:dbname]; FMDatabase * database = [FMDatabase databaseWithPath:path]; FMResultSet *rs = [database executeQuery:@"select * from name;"]; while ([rs next]) { NSLog(@"%d %@", [rs intForColumn:@"nid"], [rs stringForColumn:@"name"]); } [database close]; } ... </pre> <p>And sorry but am unable to use the code block, so using a pre again.</p> <p>Edit: When I turn logging on in FMDB, like this:</p> <pre> FMDatabase * database = [FMDatabase databaseWithPath:path]; [database setLogsErrors:YES]; if (![database open]) { NSLog(@"Could not open db."); } else { NSLog(@"DB Open...."); } FMResultSet *rs = [database executeQuery:@"select * from 'name';"]; while ([rs next]) { // just print out what we've got in a number of formats.

    1. CO"no such table: name" a wild stab in the dark here, but it looks like you don't have a table called "name" in your database.

    2. COI actually verified this using the Firefox extension, SQLite Manager, and also did a .dump in the terminal and both of them negate the claim in the Xcode console, so am out of luck on that thought as well.

Querying!

 
Guidance
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).
