How to know if I have permissions in SQL Server

Hello everyone, today we are going to tell you how to know if I have permissions in SQL Server. For this we will use the function that the system gives us HAS_PERMS_BY_NAME .
You can find all the complete information in the official documentation at the following link:
Although we are going to see the most common operations.


The general syntax of the function is:

HAS_PERMS_BY_NAME (securable, securable_class, permission
 [, sub-securable] [, sub-securable_class])

Inside the syntax:

  • securable : It is the element on which we want to know if we have permissions or not. If the element is of type server, this value must be specified to NULL.
  • securable_class : It is the type or class of element on which we act. You can find out the types of possible elements using the following query:
SELECT distinct (class_desc) FROM sys.fn_builtin_permissions (default);
How to know if I have permissions in SQL Server
  • permission : It is the permission you want to ask about.
    If you need to know about any permission, and not about a specific one, there is the wildcard ‘ ANY ‘.
  • sub-securable : If the element can be divided into sub-elements, for example, if you want to know the permissions on columns of a table.
  • sub-securable_class : The type or class of the subitem.

What value does the function return

When executing the query on the function, if the user has the permission, the function returns value 1, if it does not have the permission, it returns 0, and NULL if the permission or the type of object does not exist or is not valid.

Let’s see how to know if I have permissions in SQL Server with examples

We are going to see some examples of the different types of objects that we can have.

To find out if I have VIEW SERVER STATE permission on the current server, since permissions cannot be checked on linked servers:


Know if I have permissions in the active DB:


Create procedures in the ‘dev’ schema:

 & HAS_PERMS_BY_NAME ('dev', 'SCHEMA', 'ALTER') AS _can_create_procs;

It can also be combined with some system tables , for example to know on which tables I have SELECT permission:

(QUOTENAME (SCHEMA_NAME (schema_id)) + '.' + QUOTENAME (name), 
 'OBJECT', 'SELECT') AS have_select, * FROM sys.tables;

And you can even know s on the columns of a specific table , in this case from the sales table:

SELECT name AS column_name, 
 HAS_PERMS_BY_NAME ('sales', 'OBJECT', 'SELECT', name, 'COLUMN') 
 AS can_select 
 FROM sys.columns AS c 
 WHERE c.object_id = object_id ('sales');

We hope it has been useful to you.
