MS Access調用填充表單域時提示參數

Question

問題： 我有un update更新查詢引用MS Access子窗體字段。該字段中有一個值，但Access仍然提示我輸入參數。我已經在語句中驗證了該字段的語法是正確的，並且查詢在我輸入參數時運行得很好，所以我知道我的查詢有效。問題是什麼？

代碼：

update t_cr_patient_admission_information 
     inner join t_cr_committee_apic 
     on t_cr_patient_admission_information.case_nbr = t_cr_committee_apic.case_nbr 
    set t_cr_patient_admission_information.physician_5 = IIf(physician_4 Is Not Null and physician_5 Is Null, t_cr_committee_apic.apic_md_for_review, physician_5), 
     t_cr_patient_admission_information.physician_4 = IIf(physician_3 Is Not Null and physician_4 Is Null, t_cr_committee_apic.apic_md_for_review, physician_4), 
     t_cr_patient_admission_information.physician_3 = IIf(physician_2 Is Not Null and physician_3 Is Null, t_cr_committee_apic.apic_md_for_review, physician_3), 
     t_cr_patient_admission_information.physician_2 = IIf(physician_1 Is Not Null and physician_2 Is Null, t_cr_committee_apic.apic_md_for_review, physician_2), 
     t_cr_patient_admission_information.physician_1 = IIf(physician_1 Is Null, apic_md_for_review, physician_1) 
    where [Forms]![frm_existing_case_lookup]![sub_frm_apic_update]![case_code_id] = t_cr_patient_admission_information.case_nbr and t_cr_committee_apic.apic_md_for_review Is Not Null; 

Answer 1

你需要從子窗體控件到窗體的引用：

Forms![frm_existing_case_lookup]![sub_frm_apic_update].Form![case_code_id] 

（假設窗體控件名字也sub_frm_apic_update）

檢查out Forms: Refer to Form and Subform properties and controls

您需要Forms!Mainform!Subform1.Form!ControlName
