Troubleshooting SQL Server - A Guide for the Accidental DBA

We spend much of our working life trying to help people solve SQL Server-related performance problems, either hands-on, during consulting, or on various online community forums. Over the years, we've been exposed to a few weird-and-wonderful SQL Server issues but, mainly, we've seen the same problems and the same misconceptions about how SQL Server works crop up time-and-again. This book is our attempt to describe, diagnose, and solve some of the most common problems associated with the currently-supported versions of SQL Server: SQL Server 2005, 2008, and 2008 R2.

SQL Server Hardware

Relational databases place heavy demands on their underlying hardware and many of these databases are mission-critical resources for multiple applications, where performance bottlenecks are immediately noticeable and often very costly to the business. Despite this, many database administrators are not very knowledgeable about server hardware. Many medium-to-large companies have completely separate departments that are responsible for hardware selection, configuration, and maintenance, and the DBA with no knowledge of hardware is often completely at their mercy. Likewise, many DBAs are also unaware of the performance implications of the various options and configurations for SQL Server, and the Operating System on which it is installed. Glenn Berry is a highly experienced Database Architect, teacher and SQL Server MVP, and his book is designed to provide the fundamental knowledge and resources you need to make intelligent choices about optimal installation and configuration of SQL Server hardware, operating system and the SQL Server RDBMS. With what you learn in this book, you'll be able to ensure that your SQL Server instances can handle gracefully the CPU, memory and IO workload generated by your applications, and that the operating system and SQL Server itself are installed, patched, and configured for maximum performance and reliability.

Converting numbers in a string with various format

Μερικές φορές κάποια πράγματα που επαναλαμβάνονται δίνουν κάποιο σημάδι που δεν πρέπει κανείς να αγνοεί. Ίσως είναι η πρώτη φορά που μου συμβαίνει κάτι τέτοιο καθώς μέσα σε διάστημα 12 ώρων μου τέθηκε πάνω από 10 φορές (σε παραλαγγές) η παρακάτω ερώτηση.

Using Window Functions in SQL Server 2012

Πάρα πολλά νέα χαρακτηριστικά έχουν μπει στον SQL Server 2012. Όπως έχω πει και σε προηγούμενα post αλλά και στην πρόσφατη παρουσίαση μου στο 39o Autoexec event κάποια είναι δημοφιλή και ακούγονται συχνά όπως τα AlwaysOn Availability Groups, Auditing Enhancements, Security Enhancements κλπ. Δικαίως και είναι δημοφιλή. Υπάρχουν όμως τόσα άλλα που δεν ακούγονται, κακώς κατά την γνώμη μου. Σε μερικά μάλιστα δεν έχει δοθεί η δέουσα προσοχή. Ομολογώ ότι και εγώ σε κάποια δεν είχα δώσει και τόσο μεγάλη...
