Opening SQLite file in iOS Issue

I'm trying to open a SQLite file and I have upload it to my projects but I always get an error no such table: Words while I can get the result in sql app.

When I debug I see that I can't enter if (sqlite3_prepare_v2(database, SqlCommand, -1, &selectstmt, NULL) == SQLITE_OK)

Please where would be my issue?

My code:

- (void)GetData{

NSString *docsDir;
NSArray *dirPaths;

dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = dirPaths[0];
_databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent:@"wordsDb.sqlite"]];

sqlite3 *database;
sqlite3_stmt *selectstmt;

if(sqlite3_open([_databasePath UTF8String], &database) == SQLITE_OK) {

    NSString *sqlString = [NSString stringWithFormat:@"SELECT words FROM Words"];
    NSLog(@"getCurrentUserInfo:%@",sqlString);
    const char *SqlCommand = [sqlString UTF8String];

    if (sqlite3_prepare_v2(database, SqlCommand, -1, &selectstmt, NULL) == SQLITE_OK) {

        NSLog(@"success!");
        while (sqlite3_step(selectstmt) == SQLITE_ROW) {
            NSString *userInfoStr = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 0)];
            NSLog(@"select result:%@",userInfoStr);
        }
    }
    else
    {
        NSLog(@"%s",sqlite3_errmsg(database));
    }
    sqlite3_finalize(selectstmt);
}
  sqlite3_close (database);
}
