具有特定和通配符條件的IIF語句

Question

我正在嘗試編寫一個查詢，該查詢將在窗體上的標誌被關閉時返回所有結果，並在標誌打開時排除特定值。我一直在尋找，但無法找到我需要的確切語法。

當我在iif語句中有'Like'（當它評估爲False）時，沒有返回任何結果。當我將Like移動到iif語句的外部時，當關閉複選框時，我會得到預期的結果。如果標誌打開，我無法得到任何結果。

有誰知道我需要寫我的iif語句來獲取所有的值，如果標誌被關閉，所有的值，但如果標誌被打開，「REPLN」？

ORDER BY MYTABLE.VENDOR_NAME;

在

where子句中你開始與「WHERE（（（MYTABLE.PO_TYPE）像」，但給你在找什麼沒有標準，然後做IIF語句把另一條款中，我去掉（ （（MYTABLE.PO_TYPE）如下面的語句

這裏我們把AND放在語句中，因爲我們只需要AND，如果它是真的，否則我們只需要一個空格來移動到下一個子句。

IIF（[表格]！[frmMain]！[ReplnExclude] =真，（[MyTable的]。[類型]）<> 「REPLN AND」， 「」））

如此充滿
