Learning SQL development can seem like an overwhelming task at first. However, mastering just a few key points will help ease your way through 80 percent of the day-to-day challenges when writing stored procedures and solving common problems. Here are three important SQL development factors to keep in mind:
Outer Joins
One of the most crucial things to understand in SQL server are joins. Joins are a way to retrieve data from two or more tables based on logical relationships between them. Joins dictate how Microsoft SQL Server ought to use data from one table to select the rows in another table.
In my experience inner joins are intuitive while outer joins can present additional hours of grief by overlooking associations in the other table(s). The outer join is the key to answering questions about what the database does not have. For example, if you need to make a query to display all the students who are without report-cards, you’ll need a left join to get all students coupled with a “where clause” to return the ones who have nulls for their report card table columns in the results.
Many talented Java script programmers have muddled through the SQL Server by deficient coding around the inner join. As a result, their queries can take five hours to run, whereas, properly written left joins, can take only two seconds to run.
Aggregation
Grouping results comes up in SQL a lot more than you might think. Knowing how to write a query when answering questions such as, “What’s the average grade for each teacher’s student list?” is invaluable. This kind of question cannot be answered with a single table or solely by joins. You’ll often find you need to use joins in conjunction with group by statements. Always write the raw query first and then look at the results. Next, you have to figure out the best way to group them, rewrite your select clause and add a group by clause in the end.
Digging Through Data
I find this is the most lacking skill in many programmers. In fact, many otherwise-talented programmers holding Master’s Degrees fail to get jobs because they couldn’t analyze rows of data objectively during interviews. It’s just something that’s not taught but is crucial to get under you belt. Why? Eventually, some query is not going to perform as you may expect. And, the only way to find discrepancies is to look at rows of data, identify what join isn’t finding a match or where bad data is throwing things into chaos. Get familiar with how joins actually work, even if you have to manually walk through the logic of a large stored procedure’s tree of joins. It’s boring and time-consuming but absolutely necessary.
Take the time to master the core skills that will make you a successful SQL Programmer and avoid queries that run for five hours!
I’ve been a technical recruiter for several years, let’s just say a long time. I’ll never forget how my first deal went bad and the lesson I learned from that experience. I was new to recruiting but had been a very good sales person in my previous position. I was about to place my first contractor on an assignment. I thought everything was fine. I nurtured and guided my candidate through the interview process with constant communication throughout. The candidate was very responsive throughout the process. From my initial contact with him, to the phone interview all went well and now he was completing his onsite interview with the hiring manager.
Shortly thereafter, I received the call from the hiring manager that my candidate was the chosen one for the contract position, I was thrilled. All my hard work had paid off. I was going to be a success at this new game! The entire office was thrilled for me, including my co-workers and my bosses. I made a good win-win deal. It was good pay for my candidate and a good margin for my recruiting firm. Everyone was happy.
I left a voicemail message for my candidate so I could deliver the good news. He had agreed to call me immediately after the interview so I could get his assessment of how well it went. Although, I heard from the hiring manager, there was no word from him. While waiting for his call back, I received a call from a Mercedes dealership to verify his employment for a car he was trying to lease. Technically he wasn’t working for us as he had not signed the contract yet…. nor, had he discussed this topic with me. I told the Mercedes office that I would get back to them. Still not having heard back from the candidate, I left him another message and mentioned the call I just received. Eventually he called back. He wanted more money.
I told him that would be impossible as he and I had previously agreed on his hourly rate and it was fine with him. I asked him what had changed since that agreement. He said he made had made much more money in doing the same thing when he lived in California. I reminded him this is a less costly marketplace than where he was living in California. I told him if he signed the deal I would be able to call the car dealership back and confirm that he was employed with us. He agreed to sign the deal.

What are the best languages for getting into functional programming?
The line between IT consulting and management consulting is quite often blurred, with overlaps between the two fields habitually happening. Worse still, most people do not understand who an IT consultant really is, or what he/she does. There are those who think the job entails fixing computers, others – selling computers and associated accessories. This is misleading though.
In a nutshell, IT consultants are professionals who aid businesses in deciding what computer tools and technologies are best placed to grow and sustain a profitable business. They work hand in hand with clients to help integrate IT systems into the latter’s business. They show clients how to use technology more efficiently, and in so doing, the client is able to get a higher return on their technology investments, and ultimately, increase the bottom-line.
IT consultants, or IT advisories, could work independently or for a consulting firm, with their clientele spread across all sorts of businesses and industries. Companies hire or contract the consulting firm to come in and analyze their IT systems and structure.
The job itself is not short of challenges, however, and the path to becoming a successful IT consultant is fraught with its fair share of ups and downs. But hey, which job isn’t? Experience is the best teacher they say, and only after you’ve worked as a consultant for a number of years will you finally gain invaluable understanding of what is expected of you. Learning from the experiences of those who’ve been in this business for long is a good starting point for those who decide to venture into the world of IT consultancy.
