Searching for Database Objects and Table Data in SQL Server

Total: 3 Average: 3.7

If you are a SQL Server database administrator or developer, you need to frequently search for specific database objects the names of which you can only partly remember. The manual approach to performing these search operations is time-consuming, especially when the database has a large number of objects.

Another scenario is one in which you want to search for specific data in all database tables. In this case, you need to run a SELECT statement multiple times based on the number of database tables or views you want to search in, or write a complex cursor to loop and search in all database tables, which requires advanced SQL Server development skills.

In this article, we will look at different ways of searching for a specific database object or data in SQL Server, going gradually from built-in methods and diving into a 3rd-party tool that makes it a piece of cake to get the requested database object or data. Read More

Accelerated Database Recovery in SQL Server 2019

An Overview of Traditional Recovery

As with all relational database systems, SQL Server guarantees the durability of data by implementing crash recovery. Durability in the acronym ACID which refers to the characteristics of transactions in relational databases means that we can be assured that if the database fails suddenly, our data is safe.

SQL Server implements this capability using the transaction log. Changes made by all Data Manipulation Operations in SQL Server are captured in the transaction log before being applied to data files (through the checkpoint process) in case it’s needed to roll back or roll forward.

Total: 1 Average: 1

In this article, I will explain the process of installing pre-requisites to deploy the SQL Server AlwaysOn availability group.

For the demonstration, I have prepared a demo set up at my work station. See the following components:

Virtual Machine Host Name Purpose
Domain Controller DC.Local The domain controller is installed on this machine
Primary Replica SQL01.DC.Local This machine acts as a Primary replica in the Availability group
Secondary Replica SQL02.DC.Local This machine acts as a Secondary replica in the Availability group. This replica is in a Synchronous commit mode
Secondary Replica with SQL03.DC.Local This machine acts as a secondary replica in the Availability group. This replica is in an Asynchronous commit mode

I will explain the following actions:

  1. Installing a failover clustering role
  2. Create a failover cluster
  3. Enable AlwaysOn availability group features in SQL Server

Using Alerts and Operators in SQL Server

Total: 3 Average: 4.3

Introduction

With all the advancements in SQL Server and data, it feels great that such native SQL tools as Alerts and Operators are still available. They are the key SQL Server Agent features that are related to anything in SQL Server automation. 

Their roles are clear:

  • Alerts, when configured, let database administrators know when a specified event has occurred. 
  • An operator is an object defined within SQL Server that maps anyone or a group that can receive notifications when these events occur.
