PermissionSetAssignment:

• Use the PermissionSetAssignment object to query permission set assignments to find out which permission sets are assigned to which users.
• Each user may be assigned to many permission sets and each permission set may be assigned to many users.
• Each PermissionSetAssignment ID represents the association of a single user and single permission set.

For example, to search for all of the permission sets assigned to a particular user:

SELECT Id, PermissionSetId
FROM PermissionSetAssignment
WHERE AssigneeId = '005600000017cKt'

To search for all users assigned to a particular permission set:

SELECT Id, AssigneeId
FROM PermissionSetAssignment
WHERE PermissionSetId = '0PS30000000000e'

Note:

You can also create a new permission set assignment, or use delete to remove a permission set that's assigned to a user. To update an assignment, delete an existing assignment and insert a new one.
