Title: Rediscovering My SQL Skills: A Journey Back to Database Mastery
Introduction: My Return to Tech and Database Design
After a 20-year hiatus from software engineering and data architecture, I returned to the tech world by founding a startup. With my background in technology, I took on the challenge of designing and building the database for our app using Microsoft SQL Server. However, I soon encountered a significant hurdle that reminded me just how long it had been since I last dealt with SQL.
The Challenge: Importing Large Data Sets
In my database project, I had four large data sets stored in Excel spreadsheets that needed to be imported into the tables I had created. Despite my experience, I struggled to get the first data set to load, facing frustrating error messages. After several unsuccessful attempts, I turned to a Fiverr freelancer for help. Thankfully, after saving the file as a tab-delimited .txt file, he successfully loaded the first data set using a Bulk Insert statement.
Revisiting the Problem: A Fresh Attempt After Frustration
Despite this initial success, my attempt to load another data set in November 2023 was met with the same frustration. I spent hours troubleshooting, but eventually gave up. However, the need to import this data became critical as our app development progressed.
Breaking Down the Process: A Step-by-Step Approach
Determined to succeed, I revisited the task last week, breaking down the SQL statement into smaller sections. I focused on first building the temp table and loading all the data into it. After a few hours of work, I was thrilled to see the temp table load successfully. I took a break to prepare for a business meeting but had a few minutes to spare before leaving.
The Success: Overcoming the Final Hurdle
With just 15 minutes before I had to leave, I decided to try running the second part of the SQL statement—the part that read the data from the temp table into the real table and dropped the temp table. To my amazement, it worked perfectly. In just a few minutes, I accomplished what had taken me hours before. It was a triumphant moment that reminded me of my past SQL successes.
Conclusion: Rediscovering My SQL Skills
This experience was not just about overcoming a technical challenge; it was a reminder that persistence and a willingness to relearn can bring you back to where you once were, no matter how long you’ve been away. The phrase from my SQL Server Database Administration class, “it sounds like a SQL Slammer to me,” came full circle as I found my groove again in SQL.
