Hi Experts,
I'm trying to update a SQL table thru Access and getting the attached error, "cant update..due to lock violations", however there should be currently no users on the system, any idea whats causing it?
below is the SQL
UPDATE dbo_EmployeesUnitstbl INNER JOIN (SELECT dbo_EmployeesUnitstbl.EmployeesID
FROM dbo_Employeestbl INNER JOIN dbo_EmployeesUnitstbl ON dbo_Employeestbl.ID = dbo_EmployeesUnitstbl.EmployeesID
WHERE (((dbo_Employeestbl.Title)="rn") AND ((dbo_EmployeesUnitstbl.Unit) In ("MRDD","ddso","group home"))))
 AS a ON dbo_EmployeesUnitstbl.EmployeesID = a.EmployeesID SET dbo_EmployeesUnitstbl.Unit = "RN – GROUP HOME"
WHERE (((dbo_EmployeesUnitstbl.Unit)="RN - LTC"));

Mostly likely that other "user" is yourself - some other code or the current form.
So double-check that.

Or, you may be able to use VBA for the update and use the simple technique described here:

Check the indices on your table (server side). There should exist on on (Unit, EmployeeID), If EmployeeID is the primary key, then test (Unit) only.
