In this article, we learned about the ALTER DATABASE SET SINGLE_USER statement. We have explored the usage of the statement and required permission to execute it. SQL SERVER DEDICATED ADMIN CONNECTION (DAC) How to connect to DAC. The DAC can be connected using SQLCMD or SSMS. To start with SSMS, specifying that you are using the DAC connection on the instance will require you to prefix your instance name with “ADMIN:”. For example, my machine would be ADMIN:win-remote. But, it will not work with object explorer connections on the left-handside.
KILL SPID COMMAND IN SQL SERVER GO. While the backup is in progress, execute the sp_who2 command to see the backup database process and note down the SPID for it. Let’s assume we want to cancel the backup. Execute the KILL SPID command, and it immediately kills the backup process. You get the following message in the backup database query window. SQL SERVER FILETABLE SQL Server 2012 introduced the SQL Server FILETABLE feature that is built on SQL FILESTREAM. We can store directory hierarchies in a database. It provides compatibility with Windows applications to the file data stored in SQL Server. SQL FILETABLE stores the file and directory attributes along with the FILESTREAM data into FILETABLE. SQL NOT EQUAL OPERATOR INTRODUCTION AND EXAMPLES Example 4: Specifying multiple conditions using SQL Not Equal operator. We can specify multiple conditions in a Where clause to exclude the corresponding rows from an output. For example, we want to exclude ProductID 1 and ProductName Winitor (having ProductID 2). Execute the following code to satisfy the condition. HOW TO DROP TEMP TABLES IN SQL SERVER Global Temporary Tables: The name of this type of temporary table starts with a double “##” hashtag symbol and can be accessed from all other connections. This is the major difference between the local and global temporary tables. If the session where the global temporary table was created is closed, the global temporary table will be dropped automatically. UNDERSTANDING THE SQL DECIMAL DATA TYPE The Basic syntax of Decimal data type in SQL Server. Let’s take a look at the basic syntax of SQL Decimal Data type first. It is denoted as below: decimal Where, p stands for Precision, the total number of digits in the value, i.e. on both sides of the decimal point. s stands for Scale, number of digits after the decimal point. DIFFERENT WAYS TO SQL DELETE DUPLICATE ROWS FROM A SQL TABLE This article explains the process of performing SQL delete activity for duplicate rows from a SQL table.. Introduction.

In this article, we learned about the ALTER DATABASE SET SINGLE_USER statement. We have explored the usage of the statement and required permission to execute it. SQL SERVER DEDICATED ADMIN CONNECTION (DAC) How to connect to DAC. The DAC can be connected using SQLCMD or SSMS. To start with SSMS, specifying that you are using the DAC connection on the instance will require you to prefix your instance name with “ADMIN:”. For example, my machine would be ADMIN:win-remote. But, it will not work with object explorer connections on the left-handside.
