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. |

5 SQL Server Monitoring Counters
SQL server monitoring utilizes SQL server counters. They enable you to measure many aspects of SQL Server performance. Collecting the data over time enables you to see historic trends for current and future SQL Server optimization efforts. You can utilize counters for your preferred metrics. Doing so will provide quick and easy ways to identify SQL server performance problems.
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
A counter of page life expectancy will measure the amount of time a page stays in the buffer cache. Their unit of measure is in seconds. If a page remains in memory it does not require SQL server queries to read from a disk. System performance increases with longer page life expectancy.
2. Batch Requests/Second
The amount of batches a SQL server can get per second is measured by batch requests/per second. It indicates how much activity SQL Server is processing. Higher numbers mean a higher number of query executions. SQL Server optimization requires periodic measurements to determine SQL Server performance over 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 resource intensive process can negatively impact your SQL performance. This measurement should be compared to batch requests/second to determine whether or not compilations are hurting performance.
4. Buffer Cache Hit Ratio
The buffer cache hit ratio measures how often SQL Server finds data pages in its buffer cache when a query requests one. Performance improves as the number reaches closer to 100. Essentially it means that a SQL server was able to grab necessary data from memory and not from a 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. SQL server performance can be degraded by the inability to retain a lock. The ideal SQL monitoring target is zero, and performance will suffer as the numbers get higher.
