I am a student studying in the second year of my BSC(IT) course , I want to be an administrator in the field of database or you can say that I want to DBA , I am quite capable of doing the simple queries in the SQL language , but I get quite confused when it comes to querying multiple tables , I get confused that what should I use instead ? Should I use joins or make use of Subqueries . Please guide me what is the actual difference between those two .
