There are numerous reasons why exists the need for SQL database scripting, i.e. transform objects to their T-SQL form. One can say that it comes natural from a need to recreate some objects on another database, some objects are needed to be sent to developers for editing, or at least to keep the scripts as one form of database backup.

SQL Server index is used mainly to retrieve data from the database tables quickly, by seeking the requested records in the table index directly, rather than scanning the overall table records. The database transactional tables are changing very frequently, and these changes will be reflected in the related table indexes. Due to these changes, the index becomes fragmented over time, with its pages stored in an unordered manner.

SQL Server Index is the key solution for most of the performance issues that the T-SQL queries suffer from. It can be used to speed up the data retrieval process from your database tables, by seeking for the requested data in the index itself, rather than scanning the overall table rows.
In this article, we will discuss the difference between rebuilding the index using Online and Offline modes.

SQL Server index can be considered as a double-edged sword. When the index is designed and maintained well, it can be used to speed up the data retrieval operations from the database tables, by providing swift access to the table rows, with no need to perform a full scan on the table’s data. On the other hand, the index may cause performance degradation on your system and slow down the data insertion and modification operations, when this index is badly designed.

The purpose behind creating SQL indexes on database tables is to enhance the performance of the queries that read data from the base table by speeding up the data retrieval processes. But these transactional tables are not static and changing very frequently over time. These changes that are performed on the database table include adding new records, modifying or deleting the existing records. As these changes should be replicated to the related table indexes, the table index will become fragmented over time.

In previous article, it was explained how to automatically compare and synchronize a shared SQL script folder with SQL Server database data, while in this article the solution for the reverse process will be explained, in case when data changes needs to be pulled from a shared SQL script folder to SQL Server database. Since a “poor man’s source control repository” is already set up and a SQL script folder already contains data changes commits from other developers, it’s time to set the reverse process in order to pull data changes from SQL script folder to a developer’s local database.

SQL Server Agent is a Windows service that is widely used by database administrators and developers to automate the different types of critical and complex business and administrative tasks, to be executed based on a regular predefined schedule. It provides us with the ability to schedule an operating system CMD command, PowerShell script, SQL Server Analysis Services command or query, SQL Server Integration Services package or simply a T-SQL script.

SQL blocking means that one or multiple SQL queries are waiting for resources that are locked by another SQL Query. SQL blocking can affect data throughput and SQL Server responsiveness significantly. SQL Server response time is a measure that shows how long the end user that has executed a query must wait until he gets a response. So, in case that a query is doing nothing while waiting on another query to release the lock on the target resource, the response time increases thus making the SQL Server less responsive.

Many SQL auditing tools and solutions are available to help DBAs achieve change-auditing and compliance goals. To achieve high performance auditing fit for a specific environment, it is important to consider all of these different SQL auditing tools which use different approaches, techniques and mechanisms to audit various SQL Server operations and events in order to choose and implement a most suitable one. In this article, we are going to look and compare 5 different SQL auditing tools which leverage different SQL Server mechanisms for auditing, including embedded auditing, transaction logs, database triggers, SQL traces and more. These are:

This article will provide an overview of automating the comparison and synchronization the data between a SQL script folder and a live SQL Server database
In the article on how to automatically compare and synchronize SQL Server database objects with a shared script folder, a “poor man’s source control repository” was explained. It was shown how to set up a SQL script folder on a shared network location, in order to “mimic” the work on a SQL source control repository, where all developers will commit their changes, without any cost concerns.

One of the most critical variables for database performance is SQL Index Fragmentation. We may face blocking, deadlocks, IO issues, Disk spill issues if the fragmentation level is not appropriately managed. It can also lead to improper execution plan as well.

One of the challenges when working with SQL source control systems is to have a sort of a “safe mechanism” that will allow developers to revert any changes made on the destination database. That kind of “mechanism” are source control labels, which are basically snapshots of the SQL source control repository captured at specific time where each object is saved as individual SQL script.

This article will cover SQL Server Agent capabilities and features as well as tools to extend and enhance these core capabilities.
SQL Server provides us with the ability to schedule the different types of administrative tasks, in order to execute it automatically with customizable configurations. These tasks can be simple queries, database maintenance tasks, such as database backup, integrity check, re-indexing or statistics update, command prompt application, Microsoft ActiveX script, Analysis Services command or complex SQL Server Integration Service Packages. The Windows service that is responsible for scheduling and executing these tasks is called the SQL Server Agent Service.
