Hi fellow Grapeviners,
Can you help with good online resources (youtube/courses) to build a solid understanding of SQL. I want a course that can help me to grasp the basics of SQL from beginner to intermediate/advance level.
This website made me understand the basics. It hardly takes one hour to complete . Once you're confident . You can start working on

And solve on Hackerrank SQL questions.
Thank you so much, i just want to know how long, will it take to have a working knowledge of SQL for Business Analyst roles?
I cannot be sure about the timeline , but If you're truly dedicated and consistent on prepping for SQL from basics to intermediate it probably takes a 2week time which is a rough estimate and rest you have to practice.

Do checkout some portfolio projects in this play list .
Which will give you some confidence .
And also do checkout SQLZOO and data lemur for SQL questions for practice.
Leetcode, Stratascratch and Danny's 8 weeks SQL challenge
Also CMU's DBMS playlist on YouTube if you want to understand the working of database in depth
For what roles are you aiming for?
I have done my bachelors and have read databases during my degree. But I am not really good at them because there has been quite some time. I have been not using SQL and not writing queries. So would love to know how I can sort of brush ...
As a 3rd yr college student i just yesterday started learning sql, which sql is being used in industry in India and around the world?
