Question

我正在尝试为以下操作运行更新命令：在名为 t_AuditCompliance_import 的表格中如果名为“Payable Time Entered By”的字段为空，请将NULL更新为“exception”。

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));"

任何帮助都将不胜感激。

Answer 1

请尝试以下操作：

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));"

Answer 2

在]和Is之间没有空格，而且在WHERE子句的开头需要一个空格。应该是

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));"

VBA UPDATE查询。将NULL字段设置为值
