Estimation of solutions effectiveness

  Here you can investigate any execution plan of SQL query retrieving data from educational databases, as well as get query total cost, number of procedural operations, and most expensive input/output and CPU estimation.
  The plan - means of optimization of SQL query - is taken from SQL Server running on the site; therefore it is identical to the execution plan received by means of QA (Query Analyzer). Optimize query to take higher place in a rating by efficiency!
