Learning SQL on SQL Server 2005 $35.99 Anyone who interacts with today’s modern databases needs to know SQL (Structured Query Language), the standard language for generating, manipulating, and retrieving database information. In recent years, the dramatic rise in the popularity of relational databases and multi-user databases has fueled a healthy demand for application developers and others who can write SQL code efficiently and correctly. If you’re new to databases, or need a SQL refresher, Learning SQL on SQL Server 2005 is an ideal step-by-step introduction to this database query tool, with everything you need for programming SQL using Microsoft’s SQL Server 2005-one of the most powerful and popular database engines used today. Plenty of books explain database theory. This guide lets you apply the theory as you learn SQL. You don’t need prior database knowledge, or even prior computer knowledge. Based on a popular university-level course designed by authors Sikha Saha Bagui and Richard Walsh Earp, Learning SQL on SQL Server 2005 starts with very simple SQL concepts, and slowly builds into more complex query development. Every topic, concept, and idea comes with examples of code and output, along with exercises to help you gain proficiency in SQL and SQL Server 2005. With this book, you’ll learn: Beginning SQL commands, such as how and where to type an SQL query, and how to create, populate, alter and delete tables How to customize SQL Server 2005′s settings and about SQL Server 2005′s functions About joins, a common database mechanism for combining tables Query development, the use of views and other derived structures, and simple set operations Subqueries, aggregate functions and correlated subqueries, as well as indexes and constraints that can be added to tables in SQL Server 2005 Whether you’re an undergraduate computer science or MIS student, a self-learner who has access to the new Microsoft database, or work for your company’s IT department, Learning SQL on SQL Server 2005 will get you up to speed on SQL in no time. |

Using SQL Server Monitoring Counters To Evaluate Performance
SQL server counters are special tools used within SQL server monitoring. They enable you to measure many aspects of SQL Server performance. Gathering this data over a period of time lets you view past trends to learn how to optimize your server for the future. You can utilize counters for your preferred metrics. Counters aid DBAs in identifying and solving SQL server performance issues.
Discover more SQL Server monitoring tactics.
Here are 5 common SQL server counters you could use while optimizing your SQL server.
1. Buffer Manager: Page Life Expectancy
The page life expectancy counter measures how long pages stay in the buffer cache. Their unit of measure is in seconds. The longer a page stays in memory the more likely SQL Server queries will not need to read from disk. System performance increases with longer page life expectancy.
2. Batch Requests/Second
Batch requests/second measure the number of batches SQL Server receives per second. This will indicate the amount of activity a SQL server is experiencing. A high number means that there are a higher amount of query executions. Optimization of a SQL server requires you to take these measurements often to discover the SQL server performance over a period of time.
3. SQL Compilations/Second
The measurement of SQL compilations/second refers to the amount of execution plan a SQL server can compile in a second. This is a process that is known to be very resource intensive and could potentially hurt the performance of your SQL server. This measurement should be compared to batch requests/second to determine whether or not compilations are hurting performance.
4. Buffer Cache Hit Ratio
A buffer cache hit ratio will determine how frequently SQL servers find data pages in their buffer cache when a query requests it. Numbers close to 100 indicate better performance, as SQL server was able to get data for queries from memory instead from disk.
Learn about the benefits of SQL Server optimization.
5. Lock Waits/Second
Sometimes SQL servers must lock the system resources to be able to handle the increased numbers of users using the system simultaneously. The lock waits/seconds counter measures the number of times that SQL Server was unable to retain a lock. Failure to retain a lock negatively impacts SQL Server performance. Ideally, zero is your SQL monitoring target. Larger numbers indicate decreased performance.
