Hello there,

The best practice to learn MSSQL is to practice on test machine while reading. Only reading will enhance your theory knowledge but as DBA you must be practical. As you said you are experienced, you must be cleared with the Basic MS SQL funda. According to my experience of learning of MS SQL I will prefer to read Stairways. the most important part as DBA is to manage logs and backup, so I will prefer you to read Transaction log management[/url] in Stairways.

However, just for interveiw purpose I will prefer to go with Pinal Dave's SQL interview Q and A[/url].
