How To Get Full Permission:Add, Delete, Update, Edit In The SQL Server Database

I wrote the following statements to update a SQL server database:

Dim MyDb As Database
Dim MyRs As Recordset

Set MyDb = DBEngine.Workspaces(0).OpenDatabase("AMD", dbDriverPrompt, False, "ODBC;DATABASE=AMD;DSN=Remote")


Set MyRs = MyDb.OpenRecordset("SELECT AllAttendanceEvents.* FROM AllAttendanceEvents ORDER BY AllAttendanceEvents.EntryTime DESC")

MyRs.MoveFirst

While Not MyRs.EOF
MyVal = MyRs!EntryTime
Debug.Print MyVal
MyRs.Edit
MyRs!Ix = 50099
MyRs.Update
MyRs.MoveNext
Wend

When it execute the red line statement, it generates the error:Cannot update. Database or object is read-only.

This error is generated isnpite that I already checked the boxes: SELECT, INSERT, UPDATE, DELETE in the Permissions page of the tables?

Please advise.
