As an experienced Oracle DBA, I bring to the table a wealth of knowledge in database administration, optimization, and most importantly - SQL. Over the years, I have had numerous opportunities to work with MySQL in addition to my proficiency in Oracle. This makes me ideal for helping you sharpen your SQL skills, especially when it comes to complex queries and subqueries.
In my career, I've worked extensively with SQL and have honed my skills beyond the basics. I understand query optimization techniques, different ways of handling subqueries, and how to write efficient code that performs well with large datasets. These insights would be extremely useful during our coaching session as I can share not just the theoretical understanding but also practical tips that can make a difference during an interview.
Lastly, as a data scientist proficient in Python and R, I am very familiar with incorporating SQL into data analysis workflows and designing scalable solutions. This means our session will not be limited to just mastering subqueries but also preparing you holistically for any SQL-related questions or challenges you may face during your interview. Let's connect and ensure you're ready to ace that SQL interview!
