When learning SQL, there are ideas and concepts you must know.
If I ask you... what's DML? What's the difference between DML and DDL? You need to know what they are and be able to articulate what each does.
If I ask you... What's Transact-SQL? You need to know it's Microsoft's flavor of SQL.
If I ask you... what's a data type? You need to know what that is and be able to provide examples. For example... what's the difference between varchar and nvarchar?
Interviewers won't have patience for candidates who don't know the basics. They will simply move on to the next candidate. My Transact-SQL course and associated study guide has all of this. You have zero excuses for not having all the basics memorized.
