I have a problem with my Objective C code and an SQLite implementation. The error line is NSAsset in the if clause, thats comment out. Here is the code:

-(void) createTable: (NSString *) tableName
         withField1: (NSString *) field1
         withField2: (NSString *) field2
         withField3: (NSString *) field3
         withField4: (NSString *) field4
{
    char *err;
    NSString *sql= [NSString stringWithFormat:
                    @"CREATE TABLE IF NOT EXIST '%@' ( '%@ "
                    "TEXT PRIMARY KEY, '%@' INTEGER, '%@' INTEGER, '%@' TEXT);",
                    tableName, field1, field2, field3, field4];

    if (sqlite3_exec(db, [sql UTF8String], NULL, NULL, &err)
        != SQLITE_OK) {
        sqlite3_close(db);
     //   NSAssert(0, @"Could not create table");
    }else{
        NSLog(@"table create");
    }
}

-(NSString *) filePath{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
    return [[paths objectAtIndex:0]stringByAppendingPathComponent:@"bp.sql"];
}

-(void)openDB{
    if (sqlite3_open([[self filePath] UTF8String], &db) !=SQLITE_OK){
        sqlite3_close(db);
        NSAssert(0, @"Database failed to open");
    }else{
        NSLog(@"Database open");
    }
}

And the error message:

*** Assertion failure in -[MainViewController createTable:withField1:withField2:withField3:withField4:], /Users/Modius/X-Code 4/BPApp/BPApp/MainViewController.m:32

UPDATE: Here the complete Log Output:

    NSString *sql= [NSString stringWithFormat:
                @"CREATE TABLE IF NOT EXIST '%@' ( '%@ "
                "TEXT PRIMARY KEY, '%@' INTEGER, '%@' INTEGER, '%@' TEXT);",
                tableName, field1, field2, field3, field4];

    Your are missing a single quote after the first field name.

    (Please note that in SQL, table/field names should be quoted with double quotes; SQLite accepts single quotes only for compatibility with MySQL.)
