VBA SQL IIF 喜欢

Question

我正在尝试在“备注 1”列中搜索关键字，return 如果找到一个字符串，如果找不到另一个字符串。

我有以下代码可以正常工作，但无法使 IIF 正常工作：

"IIF([Remarks 1] Like '%Pizza%','Pizza','Other') AS [Desc2], " _

（稍后需要对这一栏进行分组）

另外：我可以嵌套IFF来搜索其他关键字吗？

错误：您试图执行的查询不包括指定表达式 'iif([Remarks 1] ALike '%Pizza%','Pizza','Other') 作为一部分聚合函数

您正在尝试使用不属于聚合的表达式。你能不能试试这样：

objRecordset.Open "SELECT [Account Name], " _
                            & "[Account Number], " _
                            & "[Currency], " _
                            & "[Description], " _
                            & "SUM([Credit Amount])," _
                            & "-SUM([Debit Amount])," _
                            & "[Desc2] " _
                        & "FROM (" & _
                        "SELECT [Account Name], [Account Number], [Currency], [Description], [Credit Amount]," & _
                              " [Debit Amount], IIF([Remarks 1] Like '%Pizza%','Pizza','Other') AS [Desc2]" & _
                        " FROM [Sheet1$] ) tmp" _
                            & "GROUP BY [Account Name], " _
                                     & "[Account Number], " _
                                     & "[Currency]," _
                                     & "[Desc2]," _
                                     & "[Description];"

PS：可能此时使用 ACE.Oledb 驱动程序比使用 Jet 更好。
