VBA UPDATE查詢。將NULL字段設置爲一個值

我試圖對以下內容運行更新命令：在名爲的表中t_AuditCompliance_import。
如果一個名爲的字段「Payable Time Entered By」爲空，請將NULL更新爲「exception」。VBA UPDATE查詢。將NULL字段設置爲一個值

DoCmd.RunSQL "UPDATE t_AuditCompliance_import SET t_AuditCompliance_import.[Payable Time Entered By] = ("exception")" _ 
     & "WHERE (((t_AuditCompliance_import.[Payable Time Entered By]Is Null));"

任何幫助，將不勝感激。

]和Is之間沒有空格，再加上你在WHERE子句的開頭需要一個空格。應該

DoCmd.RunSQL "UPDATE t_AuditCompliance_import SET t_AuditCompliance_import.[Payable Time Entered By] = ("exception")" _ 
& " WHERE (((t_AuditCompliance_import.[Payable Time Entered By] Is Null));"

嘗試以下操作：

DoCmd.RunSQL "UPDATE t_AuditCompliance_import SET t_AuditCompliance_import.[Payable Time Entered By] = ""exception"" " _ 
    & "WHERE (((t_AuditCompliance_import.[Payable Time Entered By] Is Null));"
