doubt regarding sql section questions

[Rakshit-Sharma-001]

Hi guys, I have just started doin questions related to sql language, but one thing that ishampering my work is that The languages available there are only sql-lite and postgre sql. As a beginner, i have learned and done some challenges only in mysql and sql server formats. I want to know is there any way to shift to my format, or available have anything in common with my learned ones, or should I learn one of postgre or sql-lite to ace into sql career. Any suggestions are helpful
