Those who have been working with SQL Server administration for a while now undoubtedly have at times referred to the old SQL Server system tables in order to automate some processes, or document their tables by for example combining the sysobjects and syscolumns tables. As per SQL Server 2005 and onwards, Microsoft added a number of Dynamic Management Views (DMV) that take simplify all kinds of management tasks.
List of SQL Server 2000 system tables and their 2005 equivalent management views, as well as a brief description what kind of information to find in the views.

There is a multitude of data to be mined from within the Microsoft SQL Server system views. This data is used to present information back to the end user of the SQL Server Management Studio (SSMS) and all third party management tools that are available for SQL Server Professionals. Be it database backup information, file statistics, indexing information, or one of the thousands of other metrics that the instance maintains, this data is readily available for direct querying and assimilation into your “home-grown” monitoring solutions as well. This tip focuses on that first metric: database backup information. Where it resides, how it is structured, and what data is available to be mined.
Solution
The msdb system database is the primary repository for storage of SQL Agent, backup, Service Broker, Database Mail, Log Shipping, restore, and maintenance plan metadata. We will be focusing on the handful of system views associated with database backups for this tip:
dbo.backupset: provides information concerning the most-granular details of the backup process
dbo.backupmediafamily: provides metadata for the physical backup files as they relate to backup sets
dbo.backupfile: this system view provides the most-granular information for the physical backup files
Based upon these tables, we can create a variety of queries to collect a detailed insight into the status of backups for the databases in any given SQL Server instance.

Databases Missing a Data (aka Full) Back-Up Within Past 24 Hours
At this point we’ve seen how to look at the history for databases that have been backed up. While this information is important, there is an aspect to backup metadata that is slightly more important – which of the databases you administer have not been getting backed up. The following query provides you with that information (with some caveats.)
-------------------------------------------------------------------------------------------
--Databases Missing a Data (aka Full) Back-Up Within Past 24 Hours
-------------------------------------------------------------------------------------------
--Databases with data backup over 24 hours old
SELECT
CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,
msdb.dbo.backupset.database_name,
MAX(msdb.dbo.backupset.backup_finish_date) AS last_db_backup_date,
DATEDIFF(hh, MAX(msdb.dbo.backupset.backup_finish_date), GETDATE()) AS [Backup Age (Hours)]
FROM msdb.dbo.backupset
WHERE msdb.dbo.backupset.type = 'D'
GROUP BY msdb.dbo.backupset.database_name
HAVING (MAX(msdb.dbo.backupset.backup_finish_date) < DATEADD(hh, - 24, GETDATE()))
UNION
--Databases without any backup history
SELECT
CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,
master.dbo.sysdatabases.NAME AS database_name,
NULL AS [Last Data Backup Date],
9999 AS [Backup Age (Hours)]
FROM
master.dbo.sysdatabases LEFT JOIN msdb.dbo.backupset
ON master.dbo.sysdatabases.name = msdb.dbo.backupset.database_name
WHERE msdb.dbo.backupset.database_name IS NULL AND master.dbo.sysdatabases.name <> 'tempdb'
ORDER BY
msdb.dbo.backupset.database_name
Now let me explain those caveats, and this query. The first part of the query returns all records where the last database (full) backup is older than 24 hours from the current system date. This data is then combined via the UNION statement to the second portion of the query. That second statement returns information on all databases that have no backup history. I’ve taken the liberty of singling tempdb out from the result set since you do not back up that system database. It is recreated each time the SQL Server services are restarted. That is caveat #1. Caveat #2 is the arbitrary value I’ve assigned to the aging value for databases without any backup history. I’ve set that value at 9999 hours because in my environment I want to place a higher emphasis on those databases that have never been backed up.
Most tips works for SSMS higher 2008 but some of them only for SSMS 2016 and above.

Import and Export Settings
Tools > Options > Environment > Import and Export Settings
You can configure so many settings in SSMS and then export it and use on all your computers. Below link provide detailed instruction and awesome Dark theme configuration: Making SSMS Pretty: My Dark Theme
3 Shortcuts can not be changed: Alt + F1, Ctrl + 1 and Ctrl + 2. For another 9 shortcuts my recommendation awesome open source Brent Ozar teams procedures and with some limitations Adam Machanic sp_WhoIsActive:
Right click on database name > Tasks > Generate Scripts …
Selecting a block of text using the ALT Key
By holding down the ALT key as you select a block of text you can control the width of the selection region as well as the number of rows. Also you can activate multi line mode with Shift + Alt keys and using keyboard arrows to format multi line code.
Script Table and Column Names by Dragging from Object Explorer
Save keystrokes by dragging Drag the Columns folder for a table in to auto-type all column names in the table in a single line.
Warning: this doesn’t include [brackets] around the column names, so if your columns contain spaces or special characters at the beginning, this shortcut isn’t for you
Dragging the table name over will auto-type the schema and table name, with brackets.
Disable Copy of Empty Text
Select a block of text to copy;
Move the cursor the place where you want to paste the code;
Accidentally press Ctrl+C again instead of Ctrl+V;
Block of copied text is replaced by an empty block;
This behavior can be disabled in SSMS: go to Tools > Options > Text Editor > All Languages > General > 'Apply Cut or Copy Commands to blank lines when there is no selection' and uncheck the checkbox.
Client Statistics
When you enable that option for your session, SQL Server Management Studio will give you more information about the client side processing of your query.
The Network Statistics shows you the following information:
Number of Server Roundtrips
TDS Packets sent from Client
TDS Packets received from Server
Bytes sent from Client
Bytes received from Server
The Time Statistics additionally shows you the following information:
Client Processing Time
Total Execution Time
Wait Time on Server Replies
Configure Object Explorer to Script Compression and Partition Schemes for Indexes
Is this index compressed or partitioned?
By default, you wouldn’t know just by scripting out the index from Object Explorer. If you script out indexes this way to check them into source code, or to tweak the definition slightly, this can lead you to make mistakes.
You can make sure you’re aware when indexes have compression or are partitioned by changing your scripting settings:
Click Tools – > Options -> SQL Server Object Explorer -> Scripting
Scroll down in the right pane of options and set both of these to True
Script Data Compression Options
Script Partition Schemes
Click OK
Using GO X to Execute a Batch or Statement Multiple Times
The GO command marks the end of a batch of statements that should be sent to SQL Server for processing, and then compiled into a single execution plan. By specifying a number after the ‘GO’ the batch can be run specified number of times. This can be useful if, for instance, you want to create test data by running an insert statement a number of times. Note that this is not a Transact SQL statement and will only work in Management Studio (and also SQLCMD or OSQL). For instance the following SQL can be run in SSMS :
CREATETABLETestData(ID INT IDENTITY (1,1), CreatedDate DATETIME)
GO
INSERT INTO TestData(CreatedDate) SELECT GetDate()
GO 10
This will run the insert statement 10 times and therefore insert 10 rows into the TestData table. In this case this is a simpler alternative than creating a cursor or while loop.
SSMS Template Replacement
One under-used feature of Management Studio is the template replacement feature. SSMS comes with a library of templates, but you can also make your own templates for reusable scripts.
In your saved .sql script, just use the magic incantation to denote the parameters for replacement. The format is simple: <label, datatype, default value>
Then, when you open the .sql script, you hit CTRL + Shift + M, and SSMS will give you a pop-up to enter your replacement values.
Color coding of connections
SQL Server Management Studio has the capability of coloring the bar at the bottom of each query window, with the color dependent on which server is connected. This can be useful in order to provide a visual check of the server that a query is to be run against, for instance to color code production instances as red, development as green and amber as test. This can also be used in conjunction with Registered Servers and CMS (Central Management Server). To add a color bar when connecting to the server click on the Options button in the Connect to Database Engine window and then select the Connection Properties window. Select the check box towards the bottom of the window and use the ‘Select…’ button to choose a color.
SQLCMD mode
Switching on SQLCMD mode enables a number of useful extra scripting style commands in SSMS. In particular you can use it to change to the connection credentials within the query window, so that you can run a query against multiple servers from the same query window. There are more details of how to do this here: Changing the SQL Server connection within an SSMS Query Windows using SQLCMD Mode
Script multiple objects using the Object Explorer Details Windows
Individual database objects, such as a table or stored procedure, can be scripted within SSMS by right clicking on the object within Object Explorer and selecting the appropriate item in the drop down menu. However if you have a lot of objects to script that can quickly become time consuming. Fortunately it’s possible to select multiple objects and script them up all together in a single query window. To do this just open the Object Explorer Details window from the View menu (or press the F7 key). If you want to script up multiple (or all) tables, select the Tables item under the relevant database in Object Explorer. A list of all tables appears in the Object Explorer Details window. Select the tables you want to script (using the Control key if necessary) and then right click and select which script option you want – e.g. to create a table create script for all tables
Registered Servers / Central Management Server
If you have a lot of servers then re-entering the details in Object Explorer every time you start SSMS can be frustrating and time consuming. Fortunately there are two facilities within SSMS that enable these details to be entered just once and “remembered” each time you open up SSMS. These two facilities are Registered Servers and Central Management Servers. These were introduced in different versions of SQL Server and work in different ways, each has its own advantages and disadvantages so you may want to use both.
To add a registered server open the Registered Servers window from the View menu (or click CTRL + ALT + G), the window should appear in the top left corner of SSMS. Right click on the Local Server Groups folder and select ‘New Server Registration…’. Enter the server details and close the window. This new server should then appear under Local Server Groups, you can then right click and open up the server in Object Explorer or open a new query window. The server details are stored locally in an XML file and so will appear next time you open SSMS. If you have a lot of servers then you can also create Server Groups to group together similar servers. One advantage of creating groups (other than being able to logically group similar servers together) is that you can run a query against all servers in the group, by right clicking the group and selecting ‘New Group’.
Central Management Server are similar to Registered Servers but with some differences, the main one being that the server details are stored in a database (the Central Management Server) rather than a local file. A significant limitation with CMS is that the CMS server itself can’t be included in the list of servers.
Splitting the Query Window
The query window in SSMS can be split into two so that you can look at two parts of the same query simultaneously. Both parts of the split window can be scrolled independently. This is especially useful if you have a large query and want to compare different areas of the same query. To split the window simply drag the bar to the top right hand side of the window as shown below.
The splitter bar allows you to view one session with two panes. You can scroll in each pane independently. You can also edit in both the top and bottom pane.
Moving columns in the results pane
It may not be immediately obvious but you can switch columns around in the results pane when using the grid view, by dragging the column headers and dropping them next to another column header. This can be useful if you want to rearrange how the results are displayed without amending the query, especially if you have a lot of columns in your result set. This works only for one column.
Generating Charts and Drawings in SQL Server Management Studio
You don’t have to settle for T-SQL’s monochrome text output. These stored procedures let you quickly and easily turn your SELECT queries’ output into colorized charts and even computer-generated art. To turn your own data into a line, column, area, or bar chart using the Chart stored procedure, you need to design a SELECT query that serves as the first parameter in the stored procedure call.
One such change SSMS got for free is the connection resiliency logic within the SqlConnection.Open() method. To improve the default experience for clients which connect to Azure SQL Database, the above method will (in the case of initial connection errors / timeouts) now retry 1 time after sleeping for 10 seconds. These numbers are configurable by properties called ConnectRetryCount (default value 1) and ConnectRetryInterval (default value 10 seconds.) The previous versions of the SqlConnection class would not automatically retry in cases of connection failure.
There is a simple workaround for this situation. It is to add the following parameter string into the Additional Connection Parameters tab within the SSMS connection window. The good news is that you only need to do this once, as the property is saved for future sessions for that SQL Server (until of course it is removed by you later.)
ConnectRetryCount=0
Working with tabs headers
You can view SPID in tabs header, quickly open script containing folder or copy script file path.
Hiding tables in SSMS Object Explorer
You can actually hide an object from object explorer by assigning a specific extended property:
Now UserName won’t be able to see Table in Object Explorer. In Fact, they won’t be able to see the table in sys.tables or INFORMATION_SCHEMA.TABLES
VIEW DEFINITION is the ability to see the definition of the object. In the case of SPs the code, same with Views and in the case of Tables it’s the columns definitions etc.
UnDock Tabs and Windows for Multi Monitor Support
From SSMS 2012 and onwards, you can easily dock/undock the query tabs as well as different object windows inside SSMS to make better use of the screen real estate and multiple monitors you have.
RegEx-Based Finding and Replacing of Text in SSMS
So often, one sees developers doing repetitive coding in SSMS or Visual Studio that would be much quicker and easier by using the built-in Regular-Expression-based Find/Replace functionality. It is understandable, since the syntax is odd and some features are missing, but it is still well-worth knowing about.
My favorite regex: replace \t on \n,. It useful in many cases when you have column names copied from, for example, Excel and need quickly get sql query.
Changing what SSMS opens on startup
You can customize SSMS startup behavior in Tools -> Options -> Environment -> Startup and hide system objects in Object Explore:
Also you can disable the splash screen – this cuts the time it takes SSMS to load for versions before SSMS 17. Right click your shortcut to SSMS and select properties. Enter the text -nosplash right after the ending quote in the path:
It is useful to create a solution of commonly used SQL scripts to always load at start-up.
Display the Solution Explorer by pressing Ctrl+Alt+L or clicking View -> Solution Explorer.
Then right click the Solution "Solution1" (0 projects) text and select Add -> New Project.
Use the default SQL Server Scripts template and give your solution a clever name.
Rename all of your SQL Code Snippets so the extension is .SQL. Drag them into the queries folder within the Solution Explorer.
Open Windows explorer and browse to the location of your solution. Copy file location address to your clipboard. Go back to your SSMS shortcut properties and add within double quotes the location and file name of your solution before the “-nosplash”.
This is the complete text within my shortcut properties:
"C:\Program Files (x86)\Microsoft SQL Server\140\Tools\Binn\ManagementStudio\Ssms.exe" "C:\Users\taranov\Documents\SQL Server Management Studio\Projects\MySQLServerScripts.ssmssln" -nosplash
Modifying New Query Template
You can modified New Query template for any instance SQL Server:
The options represent the SET values of the current session. SET options can affect how the query is execute thus having a different execution plan. You can find these options in two places within SSMS under Tools -> Options -> Query Execution -> SQL Server -> Advanced:
As well as Tools -> Options -> Query Execution -> SQL Server -> ANSI:
Using the interface to check what is set can get tiresome. Instead, you can use the system function @@OPTIONS. Each option shown above has a BIT value for all 15 options indicating whether or not it is enabled.
@@OPTIONS takes the binary representation and does a BITWISE operation on it to produce an integer value based on the sum of which BITS are enabled.
Default value for SELECT @@OPTIONS is 5496. Let’s assume for a moment that the only two options that are enabled on my machine are ANSI_PADDING and ANSI_WARNINGS. The values for these two options are 8 and 16, respectively speaking. The sum of the two is 24.
