Hands-On Project 7-1: Monitoring and Analyzing Performance For this hands-on project, you will use the SQL Server named instance SQLSERVERHOA and the HandsOnOne database and tables that you created in previous chapters. The objective of this project is to practice using Windows utilitics and SQL Server management tools to monitor nce and diagnose query perf 1.

Explanation / Answer

As per given data SQL statements:

This following explanation for determine the number of sessions which are are connected to any database server that is SQL server.

Following procedure for viewing the DB connections which are currently connected to DB:

*SQL select statement*

SELECT

DataBase_NAME(dbid) as DBName,

COUNT(dbid) as ConnectionsCount,

loginame as LoginName

FROM

sys.sysprocesses

*where condition for which is grater then bdid*

WHERE

dbid > 0

*grouping statements through bbid,loginame by using GOUP BY statement*

GROUP BY

dbid, loginame

*this statement gives toatal *

SELECT

COUNT(dbid) as TotalConnections

FROM

sys.sysprocesses

WHERE

dbid > 0

To performing all the above statements in SQL server for count of number of connections we need to use ‘sysadmin’ role , if we are not using it will shows single row and a count of only one connection as the result.
