Will my YOE as SQL developer hold any value if i were to become a Data Analyst?
I'm currently working as an PLSQL Developer with 1.3 YOE in a prod support team. My daily tasks require resolving bugs with the product, deliver new changes in the system etc. The only tool I use is Oracle PLSQL Developer, ireport so I wanted to upskill myself and move into Data Analytics since I'm pretty good with SQL and Excel already. I wanted to know if my years here as SQL developer will be of any use if I want to apply for Data analyst role requiring say 1-2 YOE or will I be treated as a Fresher Data Analyst since that would be my first job as a Data analyst. Thanks for your help
