What to do to study SQL for appearing in job interviews?
-
I want to study SQL. Purpose: To attend job interviews in 'Software Testing' domain. Most software companies here in India have SQL as one of the key skill requirement for the positions. I understand that SQL would not be the main tool for testing. I guess it would be used for accessing the bugs database. So how should I go about putting SQL in my resume? My questions: Should I be installing Oracle or Microsoft SQL Server? What among these should I be studying? SQLPlus, MySQL or PL/SQL?

Answer:
it's more important to understand general concepts, it doesn't matter which SQL you use, as most syntax is very similar.

Might try http://www.w3schools.com/sql/default.asp for the basics on how to format a query. As for the DBMS, it's kind of a coinflip but doesn't really matter as far as core SQL is concerned...99% of the code in any given query is going to be identical no matter which DBMS you use - the differences are fairly minor for the most part such as different extensions doing the same thing (TOP vs LIMIT) and different built-in functions (mainly for date conversions and the like.) Scripting languages are another story - there, the differences are much more than cosmetic (PL/SQL vs T-SQL, etc.)
