  • Prevent SQL injection from form-generated SQL.

    - by Markos Fragkakis
    Hi all, I have a search table where user will be able to filter results with a filter of the type: Field [Name], Value [John], Remove Rule Field [Surname], Value [Blake], Remove Rule Field [Has Children], Value [Yes], Remove Rule Add Rule So the user will be able to set an arbitrary set of filters, which will result essentially in a completely dynamic WHERE clause. In the future I will also have to implement more complicated logical expressions, like Where (name=John OR name=Nick) AND (surname=Blake OR surname=Bourne), Of all 10 fields the user may or may not filter by, I don't know how many and which filters the user will set. So, I cannot use a prepared statement (which assumes that at least we know the fields in the WHERE clause). This is why prepared statements are unfortunately out of the question, I have to do it with plain old, generated SQL. What measures can I take to protect the application from SQL Injection (REGEX-wise or any other way)?

  • switch to mysqli a good idea?

    - by Rob
    I'm considering switching to mysqli for all my php projects. The way my code is written (I run very simple websites and built my own basic framework which I use across all of them) I shouldn't have too many problems modifying the functions and classes. However, i've only heard positive things about prepared statements, bar a few grumblings about the php functions available, most notably the lack of a simple replacement for using mysql_fetch_array in a while. This sounds a bit too good to be true, so I wondered if anyone could highlight some of the issues with using prepared statements, such as speed and resource usage.

  • PDO::ATTR_EMULATE_PREPARES => false

    - by user264058
    I'm new to php and PDO ,so i read this response to a similar post- Does PDO really not use prepared statements with mysql? Yes, by default (at least with version I tested) but native mode can be turned on manually. If not, can it be forced to do so By employing PDO::ATTR_EMULATE_PREPARES setting, the name is pretty self-explanatory. $dbh-setAttribute( PDO::ATTR_EMULATE_PREPARES, false ); should you do that? That's hardest question of them all. Well, I'd say - yes, you should. If you choose PDO as your db driver, there is no point in using it in the emulation mode. by YOUR COMMON SENSE Aren't prepared statements secure from SQL injection, why change if from 'true'-false?? what is native mode??

    - by Jimmy
    Hi I'm trying to write a piece of code for a simple verification method as part of a MVC. At present the SQL is not written as a prepared statement so obviously it is at risk to a SQL injection so any help in regards to writing the SQL as a prepared statement would be really helpful. The method which is in the User model. public boolean getLoginInfo() { try { DBAccess dbAccess = new DBAccess(); String sql = "SELECT username, password FROM owner WHERE username = '" + this.username + "'AND password = '" + this.password + "';"; dbAccess.close();dbAccess.executeQuery(sql); dbAccess.close(); return true; } catch (Exception e) { return false; } } I want to get the size of the result set which is generated by the SQL query and if the size of it is 1 return true else it's false. If you need more info on the rest of the MVC just post and I'll get it up here.

  • Are there any books that teach techniques for effective pair programming?

    - by Paul D. Waite
    I’ve just read the pair programming chapter of ‘Making Software’ by Andy Oram, and I’d like to try it when I next get an opportunity. The chapter mentions that in one of the studies, the subjects were initially given instruction on effective pair programming. Are there any books (or chapters of books) that I could read to get a good grounding in how to do pair programming effectively, so that I’m more prepared?

  • Top Ten Things to Do Before Hiring a Web Developer

  • My Reference for Amy Lewis

    - by Denise McInerney
    The 2013 election campaign for the PASS Board of Directors is underway. There are seven qualified candidates running this year. They all offer a wealth of experience volunteering for PASS and the SQL Server community. One of these candidates, Amy Lewis, asked me to write a reference for her to include on her candidate application. I have a lot of experience working with Amy and was pleased to provide this reference: I enthusiastically support Amy Lewis as a candidate for the PASS Board of Directors. I have known and worked with Amy in various PASS' volunteer capacities for years, starting when we were both leaders of SIGs (the precursors to the Virtual Chapters.) In that time I have seen Amy grow as a leader, taking on increasing responsibility and developing her leadership skills in the process. From the Program Committee to the BI Virtual Chapter to her local user group's SQL Saturday Amy has demonstrated a capacity to organize and lead volunteers. A successful leader delivers results, and does so in a way that encourages and empowers the people she is working with; Amy embodies this leadership style. As Director for Virtual Chapters I have most recently worked with Amy in her capacity of DW/BI VC Leader. This VC is one of our largest and most active, and Amy's leadership is a key contribution to that success. I was pleased to see that Amy was also thinking about succession and prepared other volunteers to take over the chapter leadership. Amy has shown an understanding of PASS' strategic goals and has focused her volunteer efforts to help us reach those goals. For the past couple of years we have been trying to expand PASS reach and relevance to SQL communities around the world. The VCs are a key vehicle for this expansion. Amy embraced this idea and organized the VC to engage volunteers in Europe & Australia and provide content that could reach SQL professionals in those regions. A second key strategy for PASS is expanding into the data analytics space. Again Amy rose to the occasion helping to shape the program for our first Business Analytics Conference and leveraging the BI VC to promote the event. By all measures I think Amy is prepared to serve on the Board and contribute in a positive way.

  • H1 Visa interview tips–What you must know before attending the interview?

    - by Gopinath
    USA’s H1 visa allows highly qualified professionals from other countries to work in America. Many IT professionals in India aspire to go to USA on H1 and work for their clients. Recently I had a chance to study H1 visa process to help one of my friends and I would like to share what I learned. With the assumption that your H1 petition is approved and you got an interview scheduled at US Embassy for your visa stamping, here are tips you must know before attending the interview Dress Code – Formals Say no to casuals or any fancy dress when you attend the interview. It’s not a party or friends home you are visiting. Consider H1 Visa interview as your job interview and dress up in formals. There is no option B for your, you must be in formals. A plain formal shirt with a matching pant is suggested for men. Tie and Suit would not be required, but if you are a professional at management level you can consider wearing suit. Women can wear either formal Salwar or formal pant-shirt. Avoid heavy jewellery, wear what is must as per your tradition or culture. Body Language -  Smile on your face Your body language reflects what you are and what’s going on in your mind. Don’t be nervous or restless, be relaxed and wear a beautiful smile on your face. A smile is a curve that sets everything straight. When you are called for the interview, greet the interviewer with a beautiful smile. Say Good Morning/Afternoon/Evening depending on time you are visiting them. Whenever appropriate say Thank You. Generally American professionals are very friendly people and they reciprocate for your greetings. Make sure that you make them comfortable to start the interview. Carry original documents in a separate folder I don’t want to talk much about the documents that are required for your H1B interview as it’s big subject on it’s own and it requires a separate post. I assume that your consultant or employer helped you in gathering all the required documents like – petition, DS 160 forms, education & job related documents, resume, interview call letters, client letters, etc. For all the documents you are going to submit at the interview make sure that you have originals in a separate folder.  If required interviewer may ask you show the originals of any of the document you submitted for visa processing. Don’t mix the original documents with the documents you need to submit for interview. Have a separate folder for them. For those who are going to stamping along with their spouse and children, they need to carry few extra original documents like – marriage certificate, marriage photos(30 numbers)/album, birth certificates, passports, education and profession related certificates of the spouse and children. Know your role & responsibilities The interviewer will ask you questions on your roles and responsibilities at client location. Be clear what is your day to day tasks at client place and prepared to face detailed questions on the same. When asked explain clearly and also make sure what you say is inline with what is mentioned in your petition and client invitation letter. At times they may ask you questions specific to the project/technology you are going to work. So doing some homework in this area will help you easily answer the questions. Failing to answer basic questions on your role & responsibilities may result in rejection. You work for your Employer at Client location but NOT FOR CLIENT One of the important things to keep in mind that you work for your employer and you are being deputed to client location on a work visa.  Your employer is going to be solely responsible for your salary, work, promotion, pay hikes or what so ever during your stay at USA. Your client will not be responsible for anything. Lets say you are employed with Company X in India and they are applying for H1B to work at your client(ex: Microsoft) in USA, you must keep in my mind that Microsoft is not your employer. Microsoft will not pay your salaries or responsible for any employment related activities. Company X will be solely responsible for all your employer related activities. If you don’t get this correctly and say to Visa interviewer that your client is responsible, then you may get into troubles. Know your client It’s always good to know the clients with whom you are going to work in USA and their business. If your client is a well know organisation then you may not get many questions from interviewer else you need to be well prepared to provide details like – nature of business, location, size of the organisation, etc.  Get to know the basic details about your client and be confident while providing those details to the interviewer. Also make sure that you never talk about any confidential details of your client projects and business. Revealing confidential details of your client may land your job itself in soup. Make sure that your spouse is also in sync with you If you’ve applied a H4 visa for your spouse along with your H1, make sure that spouse is in sync with you. Your spouse also should know the basic details of your job, your employer, client and location where you will be travelling. Your spouse should also be prepared to answers questions related to marriage, their profession(if working), kids, education, etc. Interviewers will try to asses your spouse communication skills, whereabouts while staying in USA and would they prefer to work USA or not. On H4, which is a dependent visa, your spouse is not allowed to work in USA and at any point your spouse should not show the intentions to search for work in USA. Less luggage more comfort You would have definitely heard that there are lot of restrictions on what you can carry along with you to an US Embassy while attending the interview. To be frank it’s not good to say there are many restrictions, but there are a hell a lot of restrictions. There are unbelievable restrictions and it’s for the safety of everyone. You are not allowed to carry mobile phones, CD/DVDs, USBs, bank cards, cameras, cosmetics, food(except baby food), water, wallets, backpacks, sealed covers, etc. Trust me most of the things we carry with us regularly every day are not allowed inside. As there are 100s of restrictions, it would be easier if you understand what you can carry along with you and just carry them alone. Ask your employer/consultant to provide you a checklist of items that you can carry. Most what you would require are H1B related documents provided by the employer/consultant Photographs All original documents supporting your H1B Passports Some cash for your travel expenses (avoid coins) Any important phone number / details written in a paper(like your cab driver number, etc.) If you carry restricted stuff then you will be stopped at security checks, you have to find people who can safely keep all the restricted items. Due to heavy restrictions in and around the US Embassy you will not find any  place to keep your luggage. So just carry the bare minimum things required so that you feel more comfortable.
