The SolidQ Journal for February just made it out by the end of February 28th. But again, it's great to see the content appearing.
I've included the second part of the article on controlling the execution context of stored procedures. The first part was in December.
Also this month, along with Fernando Guerrero's editorial, Analysis Services guru Craig Utley has written about aggregations, Herbert Albert and Gianluca Holz have continued their double-act and described how to automate database migrations, Marino Posadas talks about migrating to Azure, Pinal Dave talks about the value of statistics, and Gilberto Zampatti covers best practices around using PowerShell with the Remote BLOB Store for SharePoint.
As usual, you'll find it here: http://www.solidq.com/sqj
