Question

I have following code (modified code from this tutorial):

    -(NSMutableArray *) getChampionDatabase
{
    NSMutableArray *championsArray = [[NSMutableArray alloc] init];

    @try {

    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString *databasePath = [[NSBundle mainBundle]pathForResource: @"Champions Database" ofType:@"sqlite"];
    BOOL success = [fileManager fileExistsAtPath:databasePath];

    if (!success)
    {
        NSLog(@"cannot connect to Database! at filepath %@",databasePath);
    }

    if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)
    {
    const char *sql = "SELECT CHAMPION_ID,CHAMPION_NAME,CHAMPION_IMG FROM CHAMPIONS";
    sqlite3_stmt *sqlStatement;

    if(sqlite3_prepare(database, sql, -1, &sqlStatement, NULL) == SQLITE_OK)
    {
        while (sqlite3_step(sqlStatement)==SQLITE_ROW) {
            championList *ChampionList = [[championList alloc]init];
            ChampionList.championId = [NSString stringWithUTF8String:(char *) sqlite3_column_text(sqlStatement,0)];
            ChampionList.championName = [NSString stringWithUTF8String:(char *) sqlite3_column_text(sqlStatement,1)];
            ChampionList.championImage = [NSString stringWithUTF8String:(char *) sqlite3_column_text(sqlStatement, 2)];
            [championsArray addObject:ChampionList];
    }
    }
        else
        {
            NSLog(@"problem with database prepare");
        }
    }
        else
        {
            NSLog(@"problem with database openning");
        }
    }

@catch (NSException *exception)
    {
    NSLog(@"An exception occured: %@", [exception reason]);
    }
@finally
    {
    return championsArray;
    }
}

After running this code i always have output : “problem with database prepare”

Then i tried to check error number of sqlite3_prepare by following code:

int ret = sqlite3_prepare(database, sql, -1, &sqlStatement, NULL);
            if (ret != SQLITE_OK) {
                NSLog(@"Error calling sqlite3_prepare: %d", ret);
            }

output: “Error calling sqlite3_prepare: 26”

error 26 – /*File opened that is not a database file */

---

File have sqlite 3 version

how is this possible? file extension is .sqlite and i can modify it in sqlite manager

Make sure you added your DB to the ressource bundle of your project and don’t put any space in your name of your DB. For example use a name like champion_db.sqlite.
