How to get list of users in SQL Server

In this department, we will understand how to fetch all the users in a SQL Server database.

Now, whenever we work on a SQL Server, there are two ways to interact with the database. The first is a GUI option by using SQL Server Direction Studio, and the 2d is past executing Transact-SQL queries. And in this section, we volition discuss both ways by illustrating some examples.

Using Transact-SQL

Now, when we are using a Transact-SQL query to go the list of users, in that location are multiple ways to list all the users. But, we will be discussing a standard way that we can employ to list users. For this implementation, we volition be using sys.database_principals view.

The sys.database_principals is a system catalog view available in SQL Server, and nosotros can easily query this view to list all the users created in the database. Hither is the query that nosotros can use to list the users in a particular database.

          Apply                          database_name                        SELECT name as username, create_date,         modify_date, type_desc equally type FROM sys.database_principals WHERE type non in ('A', 'G', 'R', '10')       and sid is non null       and proper noun != 'invitee'        

In the higher up code, we simply need to specify the database name in place of database_name . And this query will return all the users available in that database.

The example related to this execution is shown beneath.

Example

Using SQL Server Direction Studio

We tin can also utilize SQL Server Management Studio to get a list of users. Only the listing will also incorporate roles and windows groups. To brandish the list nosotros have to follow the given steps.

• Outset, movement to "Object Explorer" and aggrandize the database that you desire.
• Adjacent, nether the database, expand the "Security" directory.
• At present, under Security, expand the "Users" selection. This will display a list that contains all the users created in that database.

The list of Users are highlighted

How to get list of logins in SQL Server

In this section, we will sympathise how to fetch all the logins available in a SQL Server example.

Once more we are going to execute this job using 2 methods. The first is by using Transact-SQL query, and the 2nd is by using SQL Server Management Studio.

Using Transact-SQL

For this implementation, we will exist using the sys.server_principals catalog view. So, to list all the logins available in a SQL Server, we will query the sys.server_principals view.

The sys.database_principals is a organisation catalog view available in SQL Server, and we can easily query this view to list all the logins created in an instance. The query that nosotros can use to list the logins is given below.

          SELECT name Equally [Login Proper noun], type_desc Every bit [Business relationship Blazon] FROM sys.server_principals  WHERE Blazon IN ('U', 'S', 'G') and name not similar '%##%' Society Past proper noun, type_desc        

In the higher up code, we are querying the sys.server_principals to select the proper noun and type column. And nosotros are as well using the WHERE clause to filter the result based upon 3 types of logins. The 'U' is for Windows login, 'S' is for SQL login, and 'M' is for Windows group login.

An example of this implementation is given below.

Instance

Using SQL Server Management Studio

We tin can also use SQL Server Management Studio to call back a list of logins. Anf for this, we accept to follow the given steps.

• First, move to "Object Explorer" and expand the server instance.
• Next, nether server, expand the "Security" directory.
• At present, under Security, aggrandize the "Logins" option. This will display a listing that contains all the logins created in the item case.

How to get listing of roles in SQL Server

In this section, we will understand how to fetch all the roles available in a SQL Server database.

At present, there are 2 means to list the roles in the SQL Server database.

1. Using Transact-SQL
2. Using SQL Server Direction Studio

Using Transact-SQL

Now, to fetch a list of roles available in a database, we will be using sys.database_principals catalog view. This catalog view contains data of each security primary in a SQL Server database including database roles. The query to get all roles in a database is equally follows.

          SELECT [name], [create_date], [modify_date]  FROM sys.database_principals WHERE type = 'R' ORDER BY [proper noun]        

In the above code, we are querying the sys.database_principals view to fetch three columns. And we are also using the WHERE clause to go all the Database roles.

In sys.database_principals blazon 'R' is used for database roles. Additionally, we can besides get all application roles by replacing 'A' with 'R'.

For example, consider the following query and result.

Instance

Using SQL Server Direction Studio

Nosotros can also use SQL Server Direction Studio to become a list of roles. For this, nosotros have to follow the following given steps.

• First, motion to "Object Explorer" in the SQL Server Management and aggrandize the database that y'all want.
• Next, under the database, expand the "Security" directory.
• Now, nether Security, expand the "Roles" pick. Now, we take ii options, either expand "Database Role" or expand "Awarding Roles" according to your needs.

How to go listing of user-defined functions in SQL Server

In this section, we will discuss How we tin fetch a list of all different types of user-defined functions created in a database.

For this implementation, we will exist using the sys.objects tabular array. The sys.objects is a organisation tabular array in SQL Server that stores information of each object created within a database.

These objects include stored procedures, functions, views, etc. And nosotros volition query this stable to list all user-defined functions available in a database. For this, we will execute the following query.

          USE                          database_name                        Become  SELECT name AS [Function Name],        SCHEMA_NAME(schema_id) Every bit schema_name,        type_desc FROM sys.objects WHERE type_desc Similar '%Role%'; GO        

To execute this given query, we simply need to provide the name of the database for which we want to listing the functions. And we have to specify the database name in place of database_name.

Subsequently execution, the query volition return all the user-defined functions created in that item database.

For improve agreement, consider the following example and issue.

How to go list of user-defined views in SQL Server

In this section, we will hash out How we can fetch a list of user-divers views created inside a database.

At present, at that place can be many dissimilar methods to become a list of user-defined views in SQL Server. In this section, we will discuss a standard approach that can exist used both in SQL Server Management Studio as well every bit control prompt.

Once again, for the implementation of this, we will use sys.objects system table. And we volition implement the following query to go the result.

          USE                          database_name                        Get  SELECT name AS [View Name],        SCHEMA_NAME(schema_id) Every bit schema_name,        type_desc FROM sys.objects WHERE type = '5'; GO        

In the above code, we only need to replace your database proper name with the database_name cord. Here is an case of this execution.

How to get list of user-divers types in SQL Server

In this section, we will hash out how we can fetch a list of user-defined types created within a database.

Till now, we were using the sys.objects system table merely information technology does not contain any data related to user-defined types. So, now we have to use the sys.types organisation table.

The sys.types is too a system table and it carries data related to column data types. So, at present we will query the sys.types table to fetch a listing of user-divers types. For this implementation, we will execute the post-obit query in the query editor.

          Utilise                          database_name                        GO  SELECT * FROM sys.types WHERE is_user_defined = ane Go        

In the above code, we are querying the sys.types tabular array to fetch all of its columns. After this, nosotros are using a WHERE clause to filter all the user-defined types from the database. For sit-in, consider the following example with the output.

How to get listing of user-divers tables in SQL Server

In this department, we will discuss how we can fetch a listing of user-defined tables created within a database.

In SQL Server, in that location are multiple means to go a list of user-defined tables, and we volition try to demonstrate near of them in this section. Most commonly, we can use 2 organization tables available in SQL Server that stores data regarding user-defined tables.

1. sys.objects
2. sys.tables

Using sys.objects

Equally explained earlier, sys.objects is a system table in SQL Server that stores rows related to objects created inside the database. So, we need to query this tabular array and filter all the user-divers tables from it.

For this, the sys.objects have a cavalcade with the name "blazon", and unlike objects are assigned some grapheme that represents that object. For the user-divers tables, that type character is "U".

Here is the syntax that we can employ to get the desired outcome.

          Utilise                          database_name                        GO  SELECT name As [Tabular array Name],        SCHEMA_NAME(schema_id) Every bit schema_name,        type_desc FROM sys.objects WHERE blazon = 'U'; GO        

Let'southward understand the implementation with the help of an case. An example with its output is shown below.

Case

Using sys.tables

The sys.tables is some other organization table available in SQL Server and it stores data related to tables. And then, we simply need to query the sys.tables table to get the required event. The syntax of this execution is equally follows.

          Utilise                          database_name                        Get  SELECT name As [Table Name],        SCHEMA_NAME(schema_id) Equally schema_name,        type_desc FROM sys.tables GO        

The execution of an instance with its output is shown below.

How to get list of user-divers stored procedures in SQL Server

In this section, we will discuss how nosotros tin fetch a listing of user-defined stored procedures from a database.

In SQL Server, there are multiple ways to get a list of user-divers procedures. And we volition illustrate the 2 well-nigh common queries to implement this chore. These queries include the use of the following ii system tables.

1. sys.objects
2. sys.procedures

Using sys.objects

Hither is the query that uses the sys.objects table to listing all stored procedures created in a database.

          Utilize                          database_name                        GO  SELECT name Equally [Procedure Proper noun],        SCHEMA_NAME(schema_id) As schema_name,        type_desc FROM sys.objects WHERE type = 'P' Get        

To use the above query, we need to replace the database proper noun with the database_name. The example of this query is illustrated below.

Example

In the above instance, we are listing all the stored procedures created within the sqlserverguides database.

Using sys.procedures

The sys.procedures is some other view available in SQL Server that stores data related to objects which are procedures in some way. Here is the query that uses the sys.procedures view to list all stored procedures created in a particular database.

          USE                          database_name                        Become  SELECT proper noun Equally [Procedure Name],        SCHEMA_NAME(schema_id) As schema_name,        type_desc FROM sys.procedures Go        

The example of this query is demonstrated beneath.

How to get listing of permissions in SQL Server

Permissions are the various levels of access provided to specified security resource. Permissions are assigned to SQL Server logins and server roles at the server level. They are assigned to database users and database roles at the database level.

In this section, we will discuss how we tin fetch a list of congenital-in permissions available in SQL Server.

For this implementation, we volition use the sys.fn_my_permissions system office. This office returns the set of permissions granted to a main on a securable. Here is a query that we need to execute to become the list of all born permissions.

          SELECT * FROM sys.fn_builtin_permissions(DEFAULT);                  

For example, consider the following screenshot given below.

Example

How to become list of active connections in SQL Server

At present, in this section, we will talk over how to fetch a list of active connections to a SQL Server database.

At present, to become the list of active connections, we will use sys.processes system view. The sys.processes view stores the data related to processes that are running on the SQL Server instance.

And these processes include both systems likewise equally client processes. The query that nosotros can apply to list the active connection is given beneath.

          SELECT DB_NAME(dbid) Equally [DB Name],        COUNT(dbid) AS [Number Of Connections],        loginame As [Login Name] FROM sys.sysprocesses GROUP Past dbid, loginame Social club By DB_NAME(dbid)        

The instance of implementing the above is also given below with its output.

How to get list of orphaned users in SQL Server

In this department, nosotros will hash out how we can fetch a list of orphaned users in SQL Server. Only before that, let's first sympathise what are orphaned users in SQL Server.

An orphaned user in SQL Server is the ane that is bachelor at the database level only its mapped login is not there at the server level. These types of users are generally created when a database is restored from a fill-in from 1 server on another server.

Next, let's understand how we can list these orphaned users in SQL Server. For this, permit'due south assume that nosotros have restored a database with the proper noun myDB from server1 to server2.

At present, to list all the orphaned users, we take to execute the following command on server2.

          USE myDB GO  EXEC sp_change_users_login report Get        

After executing the higher up query, we will get a resultset with two columns. The outset is the UserName and the second is the UserSID column.
