I would like to know is there any website which offers free practice exercises on SQL/Oracle queries? Preferably advanced level queries. Thanks, Kruti

Thanks. We'll let you know when a new response is added.
Free website suitable for learning sql queries is sqltest.net

The site is easy to use, works properly and there is no need to install any software. For proper functioning it is necessary to first enter the script table with the click of a button “insert table scripts” and then you can run the query by clicking the SQL Test. You can perform SQL tests against dual table, as shown in the test case.

    SELECT Title, FristName, LastName, Phone, Location
    From Employees, Office
    Where Employees.EmpID=Location.EmpID AND
    Dept= “operation”
    Order By Employees,

    There is something wrong and I can't figure it out.

    theirs something wrong and i cant figure it out.   Since you didn't tell us anything about what the DBMS is nor anything about the tables nor what is wrong, it's not easy for us to figure anything either. (Though there's at least one and possibly two fairly obvious possibilities.)   And since this has nothing to do with this question thread, I suggest you open a new question. When you do, give us enough information to make useful guesses at least.   Tom

    I have just discovered and am enjoying 
    beyondrelational.com

    Puzzles and tutorials on TSQL, PLSQL, and more, on multiple levels. It also appears to be another site for helping one another out.
