Set value in column guided by result from select. SQL Server - sql

Question

I have a ready select.
SELECT
[c.MySiteRole].[Id],
[c.MySiteRole].[EmployeeId],
[c.MySiteRole].[RoleId],
[c.MySiteRole].[SiteId],
[e.Site].[Id],
[e.Role].[Id],
[e.Role].[Name],
[e.Role].[RoleTypeId]
FROM
[MySiteRole] AS [c.MySiteRole]
INNER JOIN
[Site] AS [e.Site] ON [c.MySiteRole].[SiteId] = [e.Site].[Id]
INNER JOIN
[Role] AS [e.Role] ON [c.MySiteRole].[RoleId] = [e.Role].[Id]
INNER JOIN
(SELECT TOP(1) [c1].[Id]
FROM [Employee] AS [c1]
WHERE [c1].[UserName] = 'MyUserName'
ORDER BY [c1].[Id]) AS [t0] ON [c.MySiteRole].[EmployeeId] = [t0].[Id]
ORDER BY
[t0].[Id], [e.Role].[Id]
In result of this select I have a list.
Next stage I need to compare the result [e.Role].[Id] from select with few other Id and they must be here, not in other table.
"first-guid-id"
"second-guid-id"
"third-guid-id".
If in result select will be coincidence with one of this id I need set for MyColumn update true. !important - coincidence must be only with guid id from this list. For example if coincidence will be with one of them and in result [e.Role].[Id] will be other guid id - need set false for my update column. It's like "isOnlyProgrammerRoles"
Now I have my update script in this case
UPDATE [dbo].[MyTable]
SET [MyColumn] = CAST (CASE WHEN UserName like '%[^0-9]%' then 0 else 1 end AS BIT)
I need to update my script to something like this
UPDATE [dbo].[MyTable]
SELECT [c.MySiteRole].[Id],
[c.MySiteRole].[EmployeeId],
[c.MySiteRole].[RoleId],
[c.MySiteRole].[SiteId],
[e.Site].[Id],
[e.Role].[Id],
[e.Role].[Name],
[e.Role].[RoleTypeId]
FROM [MySiteRole] AS [c.MySiteRole]
INNER JOIN [Site] AS [e.Site]
ON [c.MySiteRole].[SiteId] = [e.Site].[Id]
INNER JOIN [Role] AS [e.Role]
ON [c.MySiteRole].[RoleId] = [e.Role].[Id]
INNER JOIN (SELECT TOP(1) [c1].[Id]
FROM [Employee] AS [c1]
WHERE [c1].[UserName] = 'MyUserName'
ORDER BY [c1].[Id]) AS [t0]
ON [c.MySiteRole].[EmployeeId] = [t0].[Id]
ORDER BY [t0].[Id],
[e.Role].[Id]
Compare the Result.Id with GUID id from list 'guidId', guidId', guidId'
if one or more coincidence from list(only from list + no more guid id in the result){
SET [MyColumn] = 1 like bit
}

Well, this solution doesn't follow the same table aliasing and it removes the unneeded brackets. I'm not sure what you mean by "no guid in the result...". Anyway, something like this
;with three_guid_count_cte(r_id) as (
SELECT
r.Id
FROM
MySiteRole AS msr on
INNER JOIN Site AS s ON msr.SiteId = s.Id
INNER JOIN Role AS r ON msr.RoleId = r.Id
INNER JOIN (SELECT TOP(1) c1.Id
FROM Employee AS c1
WHERE c1.UserName = 'MyUserName'
ORDER BY c1.Id) AS t0 ON msr.EmployeeId = t0.Id
INNER JOIN (values (guid1), (guid2), (guid3)) t(v) on r.Id=t.v
HAVING
COUNT(*)>1;
UPDATE m
SET [MyColumn] = CAST(1 AS BIT)
FROM
[dbo].[MyTable] m
INNER JOIN three_guid_count_cte tgc on m.????=tgc.r_id;
