Error trying to open DB in SQLite (iOS)

Question

Am making an iOS apps with an embedded SQLite database. So I make my DB in a SQLite administrator and drag it to my Xcode project, like in the tutorial says. When I try open my DataBase, I get this error: "out of memory". Dont know if it is a SQLite bug or something, but my file is really small to get a memory problem.

This is my code to init my DataBase:

- (id)initWithPath:(NSString *)path {
if (self = [super init]) {
 BOOL success;
 NSError *error;
 NSFileManager *fileManager = [NSFileManager defaultManager];
 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *documentsDirectory = [paths objectAtIndex:0];
 NSString *dbPath = [documentsDirectory stringByAppendingPathComponent:@"SoundLib_DB.sqlite"];
 if ([fileManager fileExistsAtPath:dbPath] == NO) {
 NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"SoundLib_DB" ofType:@"sqlite"];
 [fileManager copyItemAtPath:resourcePath toPath:dbPath error:&error];
 }
 success = [fileManager fileExistsAtPath:dbPath];
 if(!success)
 {
 NSLog(@"Cannot locate database file '%@'.", dbPath);
 }
 sqlite3 *dbConnection;
//Here is when I get the error, at trying to open the DB
 if (sqlite3_open_v2("SoundLib", &dbConnection, SQLITE_OPEN_READWRITE, NULL) != SQLITE_OK) {
 NSLog(@"[SQLITE] Unable to open database!");
 NSLog(@"%s Prepare failure '%s' (%1d)", __FUNCTION__, sqlite3_errmsg(database), sqlite3_errcode(database));
 return nil;
 }
 database = dbConnection;
}
return self;

}

• omz: You're not using the actual file path of your database in the sqlite3_open_v2 call.
• Rok Jarc: Yes, that sqlite3_open_v2("SoundLib", &dbConnection,... is not just fishy, it's wrong

Answer 1

Error may be because you need to pass databasepath as UTF8String. I see you are passing "SoundLib". You can not directly pass like that.

 if (sqlite3_open([dbPath UTF8String], &databaseHandle) == SQLITE_OK)
{
 //dbPath is your full database path you getting above
}

P.S. Also have dbpath as const char

const char *dbpath

• rohan-patel: Anytime. Word of advice: Do keep habit of reading official Apple docs. Relying only on tutorials will build a weak foundation of your coding skills.

Answer 2

Change your opening process so that it looks like this... It works for me ;) I guess your main mistake is that you forgot the UTF8String....

sqlite3 *database;
int result = sqlite3_open([dbPath UTF8String], &database);
if (result != SQLITE_OK) {
 sqlite3_close(database);
 NSLog(@"Error opening databse");
 return;
}

• FelipeDev.-: I mark as correct the previous one, just because I read it first, but this works too man. Thank you.
