A Guide to Solve Damaged SQL Server Issues

People work with SQL Server every day without being a production DBA. Hence, a point may come when you must consult professionals for different performance troubleshoots and projects. It’s because data security has become a crucial part of everyday life. It is a marvellous thing, as it is a vital way of learning new techniques and concepts related to SQL Server. If you want to sharpen your skills, you have to continue building content as a part of your current role. 

Over the years, various issues have cropped up that have made computer users consider SQL Server in detail. There is no point avoiding these issues instead of finding an easy fix. The benefits, cost, and risk of the related application design for senior administrators are critical. You cannot avoid these glitches because they will affect data security in the long run. Before delving deep into the solutions of SQL Server issues, people must understand the common problems in detail. 


A well-established problem associated with SQL Server is indexes. It does not mean that SQL Server does not perform indexes well. These days the servers perform indexing very well, indeed. Now, the issue related to SQL Server and indexes is how easy it is for computer users to commit mistakes when performing indexing. Wrong indexes, missing indexes, many indexes, too few indexes, and outdated statistics are common issues that users often face every day. 

Although the area covers various grounds, the truth is that regular maintenance and a little bit of cautiousness will take care of these problems and help them disappear. Keep in mind that you must stay alert and perform the indexing task with precision as an end-user. If you feel the process is complex for you, you may take the help of professionals who know everything about queries, indexes, table statistics, and proper designing. 

Wrong design decision

For ensuring commendable database performance, you have to start with a robust database design. If you have issues with improper database choice, lack of info archiving, relational database issues, and use of nested view, you cannot take these problems lightly. There are no keys defined at all. You might have excel spreadsheets compiled with PowerShell that create a cluster node with a terabyte of RAM and flash drive. It’s challenging to alter the existing systems after deploying the same to production. Thus, poor design choices may linger for a long time and create a poor impression. Hence, making decisions regarding design and overall layout is your responsibility. 

Bad code

Poor code is a subjective term where each user has a unique definition. Improper code covers unnecessary cursors, user-defined functions, incorrect clauses, and much more. Along with the wrong design, the destructive code will further lead to concurrency problems that will result in locking, blocking, and deadlock. Since there are multiple combinations of poor code along with poor design, the significance of examining the database is well-established. Only a competent individual with years of experience and expertise in this field can help you solve the issue in such a scenario. 

Object-relational mapping

ORM or object-relational mapping is a tool that is used all across the globe. These are code-first generators and are used to work well. However, improper use of these tools results in bad performance and poor use of resources. ORM often results in frequent problems which are not easy to identify and thereby play the role of a fugitive. Remember that ORM leaves its fingerprints on the spot, and thereby you have to undertake a careful examination to understand the underlying cause. By discovering blog entries, you may appreciate performance issues related to ORM. Some tools will help you summarise ORM deployment, which you can use to your advantage. 

Default configuration

The installation of SQL Server is an easy task that does not require any understanding of the default configuration option. The option stands applicable for those who possess virtualised instances related to SQL Server. You get a chance to select default options which are sometimes not fair for the SQL Server. Tempdb configuration, MAXDOP, and default file growth are some examples you may use for configuring SQL Server before switching it on. When you see similar issues cropping up now and then, you should build a firewall inside and outside the SQL Server to ensure decent performance. An appropriate understanding of the configuration of SQL Server is necessary if you want to grab the best from this tool. 

These are some of the issues you may discover while working with a damaged SQL server. Remember that the Internet is full of hackers and frauds. They always want access to your system that results in troubleshooting performance. By reviewing the design, backing up current data, and creating firewalls, you may deal with these issues and ensure the security of your data. 

Easy ways of dealing with SQL Server issues

If you want to have a worthwhile experience with SQL Server, you must regularly back up your data. Moreover, you must understand the underlying cause of performance issues and the best ways of avoiding them. The happy performance will then tune in. 

•    Check the wait statistics: Checking the statistics is the first step to deal with the issue. SQL Server continually tracks the execution threads. The information is critical when trying to pinpoint the cause of performance problems. Discovering the reason is easy, but interpreting the info and solving the issue requires time and technical knowledge. Hence, it would benefit if you had a professional who belongs to such an environment and could pinpoint the underlying cause. 

•    Run index maintenance: Yes, running index maintenance is another reliable way of dealing with the workload. Frequent changes in data and increasing workload often hamper the system. Check the index fragmentation regularly whenever it reaches 30% or extra. You may schedule weekly index maintenance to help update the statistics. 

These are some simple ways of ensuring proper work of indexes and functioning of SQL Server. If you are still not sure how you will manage these issues, you may contact professionals to help you out.
