[강의] 인프런 '백문이불여일타 데이터 분석을 위한 기초~중급 SQL' 완강! 문제리스트

 

기초 https://inf.run/yeQg

중급 https://inf.run/pDn2

중급 문제풀이  https://inf.run/bzA1

 

 

수강의 목표는

기존에 배웠던 SQL 기초와 SQLD 시험 준비를 자연스럽게 연결하면서 내용을 갈무리하는 것.

이론적인 부분과 문제풀이를 겸하면서 차근차근 배우니까 원하던대로 정리가 잘 됐다. :D

'백문이불여일타'라는 이름처럼 한 번이라도 더 타이핑하면서 익히는 게 좋은 방법이라는 생각이 든다.
