Where to find training resources on complex T-SQL?

Hi All,

I have 5 years of experience working on SQL server, I am looking for a job change, before that i want to get myself comfortable writing some complex sql queries. I went through few websites but could not get the proper once.  Can anyone help me in finding the that, so that I can find some really complex sql queries.

Thanks in advance,

Read some of Joe Celco's books ("Thinking In Sets" is a must read and "SQL for Smarties").

Here are a couple articles, as well, that may wet your appetite for "more complex" queries.
First this, then this (look at the cross joins at the end).

Stay here in EE and try to help others with they queries. There's a topic only for SQL Query Syntax. You'll learn a lot just for trying to help others. Their doubts now can be yours in the future.
Good luck.

Curiosity overwhelms me ... What did you do during five years of SQL Server experience that did not involve writing queries?

Everyone here will have different opinions on SQL books/training based on their experience.  From what I've read, Itzik Ben-Gan's T-SQL Fundamentals would be a good choice.

And as Vitor stated above, asking questions here on EE is an excellent choice.  Make sure you tell people that you're self-studying and trying to understand concepts, so we don't confuse you with a 19-year old junior college student trying to get others to do their homework for them.

Good luck.

Itzik Ben-Gan's stuff is magnificent.  Be sure to review his "Gaps and Islands" queries, as it provides extremely valuable technique and shows how to think along set-based lines to solve such problems.

Take some time to learn the structure of Experts-Exchange too.  There are video tutorials here as well as a "groups" section (which was just launched this week). Also, as Vitor said, helping others will be one of the best things you can do to broaden, and sharpen, your skill set.

Many established SQL Server experts here on EE have written multiple articles on various SQL Server topics, and at the bottom of each one is a big green 'Was this article useful?' button.  You like our articles, and maybe write feedback in the comments section, and we'll like you back.
