SQL UPDATE语法错误问题

Question

我有一些SQL，我收到语法错误，但无法解决原因：

守则：

CurrentDb.Execute "UPDATE [MS Access;pwd=" & strPassword & ";database=" & DBpath & "\" & DBnameVoice & "].[" & tblhistoric & "] " & _
         "SET NudgeSent = '" & SendNudge & "' " & _
         "WHERE [ID] = '" & UID & "'"

为什么我感到困惑： 我有完全相同的代码，但更新不同的列，它工作正常，我错过了什么？

收到错误：

UPDATE语句中的语法错误

类似的代码我的确有效：

CurrentDb.Execute "UPDATE [MS Access;pwd=" & strPassword & ";database=" & DBpath & "\" & DBnameVoice & "].[" & tblhistoric & "] " & _
         "SET AllocatedTo = '" & Allocateto & "' " & _
         "WHERE [ID] = '" & UID & "'"
