What’s Database Star All About?

Ben BrummGetting started in the IT industry can be pretty hard. You’ve graduated from college or university, got some good marks, and now you’re starting out in the world of software.

It doesn’t matter what kind of role you’re getting in to. Software development, software testing, business analysis, database development, application support. Working in these fields is a big change from studying them at college, and there’s a lot to know about the IT industry if you want to get ahead in your career.

That’s where Database Star comes in. I enjoy providing useful information, sharing advice, and giving resources to help YOU get ahead in your career.

I’ve been helping people improve their careers for a few years. See what they have to say:

  5. Hi Ben!

  6. Greetings. I just joined the Academy for SQL Developer and PostgreSQL. I like to be able to print off the course materials and make my notes, highlight, etc. I was able to do this for PostgreSQL bu can’t find the notes for SQL Developer. Kindly point me in the right direction.

    1. Thanks for joining! I have some of the courses (mostly the newer courses) include the slides and a PDF version of the course, as I created it when I created the course. Some of the older courses, such as “SQL Developer Jumpstart” don’t have this. (I plan to recreate these older courses, and when I do, I’ll create the slides and PDFs for them).

  7. Hello Mr. Brumm,

    I was searching on YouTube for some information on SQL and database creation and stumbled upon your page. I am not a programmer or a data analyst. I am looking for someone to help me build a DataMart and eventually an app for a business idea that I have. I have tried fiverr , but I can’t find someone who can develop a small test database and some SQL queries to help me design a proof of concept model. Do you or do you have contacts that would be willing to help me. I am willing to pay.

    Thank you.

      Hi David,

      I would be happy to help you with what you are looking for. I am not completely into database background, but I have good experience working with Db2 database , creating complex SQL queries for the mainframe applications. I am passionate about database and I am very much interested to work in this field. I am on a lookout for database developer roles for which I would like to do some real time database developer role. If you think I would be a right fit I can help you preparing one and please feel free to contact me in LinkedIn.

  8. Hello Mr.Ben
    Greetings for the day! Presently I am pursuing my Data Engineering Course. Also preparing for a mock interview I came across your website. I must say the content is very good. It is helping a lot to understand the SQL concept easily.
    Kindly keep on adding such content.
    Thank you for everything.

  9. I just stumbled on to this site for SQL JSON queries and decided to explore. I now have it booked marked, very nicely done. I like the format that shows all the details for leaning a new concept. Thank you for your effort to help others.

    Hi Ben I have been on the Oracle website and tried to register for the exam but it is not straightforward. I select Oracle Database SQL 1Z0-071 but when it comes to confirm it seems to give a generic name with a list of maybe 30 exams, Oracle Database SQL 1Z0-071 being one of them. Do I select this generic name?
    I have tried contatcing Oracle but you have to email in and wait for reply.. contacting oracle is slow and tedious
    Please can you help Ben

  14. Hi,

    I’m currently working with Microsoft SQL Server 2022, and I’m encountering an issue when trying to truncate a table. The error message I’m receiving is as follows:

    “Cannot truncate table because it is being referenced by a FOREIGN KEY constraint.”

    To address this error, I attempted to use the following query:

    sp_msforeachtable “ALTER TABLE ? NOCHECK CONSTRAINT all”

    However, even after running this query, I’m still encountering the same error. Can anyone help me understand what I might be doing wrong or suggest an alternative solution to successfully truncate the table?

    Thank you!

  15. Nice content and very helpful for a beginner to get started on learning database.
