how to delete user in SSRS using TSQL - reporting-services

Question

I have some users in SSRS which I want to delete.
where I try to run:
DELETE FROM dbo.Users
WHERE dbo.Users.UserName = 'domain\user'
I'm getting the following error:
Msg 547, Level 16, State 0, Line 1
The DELETE statement conflicted with the REFERENCE constraint
"FK_Catalog_CreatedByID". The conflict occurred in database "ReportServer",
table "dbo.Catalog", column 'CreatedByID'.
The statement has been terminated.
How can I delete users (and all their permissions from SSRS database?

Answer 1

I run into the same problem that I wanted to permanently remove users from the SSRS database. So I made this SQL syntax (BACKUP YOUR DB BEFORE!):
DECLARE #username varchar(255); SET #username = '<username>';
DECLARE #ownerid uniqueidentifier; SET #ownerid = (SELECT UserID FROM Users WHERE UserName = #username)
BEGIN TRAN
UPDATE Subscriptions SET ModifiedByID = OwnerID WHERE ModifiedByID = #ownerid
DELETE FROM Subscriptions WHERE OwnerID = #ownerid
DELETE FROM Schedule WHERE CreatedById = #ownerid
DELETE FROM PolicyUserRole WHERE UserID = #ownerid
DELETE FROM Users WHERE UserID = #ownerid
COMMIT
Replace the <username> with the user you want to remove and that's it. But be aware that this also removes other data from this user as well.

Answer 2

The error is clear that you have data in other tables that references the Users table which you are trying to delete.
So you have two options:
Remove the constraints from the Users table and then delete the record and reapply all the constraints again.
Remove the data from the referenced tables where your User table is getting referenced.

select UserID, u.UserName

from
ReportServer.dbo.Users as u
where userid = 1 -- expression
delete from [ReportServer].[dbo].[PolicyUserRole]
where UserID in (select UserID from #rs_users)
declare #user_name nvarchar(100), #pattern_start nvarchar(300), #pattern_end nvarchar(100), #result nvarchar(max)
declare #start_position int, #end_position int, #sec_data_id uniqueidentifier
DECLARE user_cursor CURSOR
FOR
select UserName
from #rs_users
OPEN user_cursor;
FETCH NEXT FROM user_cursor INTO #user_name
WHILE ##FETCH_STATUS = 0
BEGIN
set #pattern_start = '<Policy><GroupUserName>' + #user_name + '</GroupUserName><GroupUserId>'
set #pattern_end = '</Policy>'
DECLARE secdata_cursor CURSOR
FOR
select SecDataID
from
[ReportServer].[dbo].SecData as sec
where
sec.XmlDescription like '%' + #pattern_start + '%'
OPEN secdata_cursor;
FETCH NEXT FROM secdata_cursor INTO #sec_data_id
WHILE ##FETCH_STATUS = 0
BEGIN
select
#start_position = PATINDEX ( '%' + #pattern_start + '%' , XmlDescription ) ,

end
FETCH NEXT FROM secdata_cursor INTO #sec_data_id
