Hello people,
In this post I will demonstrate a script that I developed that has been very useful in my daily life and has the function of copying permissions from one user to another, with the option of just generating the SQL script or actually copying the permissions, which they can be at the level of a specific database or instance.
If you just want to view the permissions of one or more users and / or generate an SQL script with that, see if the article Checking a user's permissions in SQL Server can help you.
To meet this need, I created a Stored Procedure in T-SQL that has the following parameters:
| Parameter Name | Description |
|---|---|
| @User_Origin | User who will have read and copied access |
| @User_Destination | User who will receive the access to copy |
| @Data base | Name of the database from which the hits will be copied. If not entered (NULL or ''), all databases will be read. |
| @Fl_Remove_Permissions | If this parameter has value = 1, the permissions of the target user are REMOVED so that they are the same as the source user (Will only be executed if @Fl_Execut = 1 too) |
| @Fl_Cria_Usuarios | If this parameter has value = 1, the script will scan the instance databases and check which ones @Username_Destination exists and @Username_Destination will create @Username_Destination users in those databases. |
| @Fl_DisplaysResults | If this parameter has value = 1, the procedure returns multiple queries detailing the current permissions of the @Usuario_Origem and @Usuario_Destino users |
| @Fl_Run | If this parameter has value = 1, all generated commands will be executed on the instance. If the value is = 0, a PRINT is displayed at the end of execution with the commands. |

1 Example
In this example, I will demonstrate how to generate the script to copy the permissions of the user "Usuario_Teste" to the user "Test" in the "master" database.
| 1 2 3 4 5 6 7 8 | EXEC master.dbo.stpCopia_Permissoes @Usuario_Origem = 'Usuario_Teste', -- varchar(max) @Usuario_Destino = 'Teste', -- varchar(max) @Database = 'master', -- varchar(max) @Fl_Remover_Permissoes = 1, -- bit @Fl_Cria_Usuarios = 1, -- bit @Fl_Exibe_Resultados = 1, -- bit @Fl_Executar = 0 -- bit |
Result:
2 Example
In this example, I will demonstrate how to generate the script to copy the permissions of the user “Usuario_Teste” to the user “Test” in all databases of the instance. When the @Database parameter is not informed, the Stored Procedure will iterate between all databases and still generate permissions at the server level and server roles.
| 1 2 3 4 5 6 7 8 | EXEC master.dbo.stpCopia_Permissoes @Usuario_Origem = 'Usuario_Teste', -- varchar(max) @Usuario_Destino = 'Teste', -- varchar(max) @Database = NULL, -- varchar(max) @Fl_Remover_Permissoes = 1, -- bit @Fl_Cria_Usuarios = 1, -- bit @Fl_Exibe_Resultados = 1, -- bit @Fl_Executar = 0 -- bit |
Result:
3 Example
In this example, I will demonstrate using the @Fl_Executar = 1 parameter, where actually changes are made to the instance by the Stored Procedure and permissions are actually copied from @Usuario_Origem to @Usuario_Destino.
| 1 2 3 4 5 6 7 8 | EXEC master.dbo.stpCopia_Permissoes @Usuario_Origem = 'Usuario_Teste', -- varchar(max) @Usuario_Destino = 'Teste', -- varchar(max) @Database = NULL, -- varchar(max) @Fl_Remover_Permissoes = 1, -- bit @Fl_Cria_Usuarios = 1, -- bit @Fl_Exibe_Resultados = 1, -- bit @Fl_Executar = 1 -- bit |
Result:
In this case, I ran the SP again to bring the updated permissions of the user “Teste”, who now has the same permissions as the user “Usuario_Teste”
That's it, guys.
I hope you enjoyed this post.
A hug and see you next.
Dirceu, Great show and congratulations for sharing these scripts. When I grow up I want to be just like you! ?
Very good, thanks for sharing.
You're welcome, Julius. Any questions, just talk and I accept suggestions for new articles kkkkkkkkkk
Is this script also for copying users to a mirror instance?
Very good script, congratulations for sharing knowledge!
However it did not help me solve my problem.
I have a user in a test database with restricted permissions (some views, two tables and two procedures), I tried to reproduce this same scenario in another test database with the most updated data and the user is unable to finalize the insert (purpose) of the procedure .Returns an error message “Error during trigger execution” pointing to a trigger on one of these tables that the user already has access to (INSERT, UPDATE, SELECT).
I used know script to see what the difference of access of this user between a database and another permissions are exactly the same, however does not work in database2.
I can say that this is permission because if I add the user in role db_owner the procedure runs without problems.
Very good your script !!! helped me a lot.
