具有特定和通配符条件的IIF语句

Question

我正在尝试编写一个查询，该查询将在窗体上的标志被关闭时返回所有结果，并在标志打开时排除特定值。我一直在寻找，但无法找到我需要的确切语法。

当我在iif语句中有'Like'（当它评估为False）时，没有返回任何结果。当我将Like移动到iif语句的外部时，当关闭复选框时，我会得到预期的结果。如果标志打开，我无法得到任何结果。

有谁知道我需要写我的iif语句来获取所有的值，如果标志被关闭，所有的值，但如果标志被打开，“REPLN”？

SELECT MYTABLE.DPT_NUMBER, MYTABLE.VENDOR_ID AS [Vendor ID], MYTABLE.VENDOR_NAME AS [Vendor Name], Sum(MYTABLE.UNITS_ORDERED) AS [Units Ordered], Sum(MYTABLE.RECEIVED_QTY) AS [Units Received], IIf(Sum([MYTABLE]![RECEIVED_QTY])=0,0,([Units Received]/[Units Ordered])) AS [Received Fill Rate], Sum(MYTABLE.ASN_QTY) AS [ASN Ship QTY], Sum([MYTABLE]![ASN_QTY])-Sum([MYTABLE]![RECEIVED_QTY]) AS [Units In Transit], Sum([MYTABLE]![ASN_QTY])/Sum([MYTABLE]![UNITS_ORDERED]) AS [Fill Rate with In Transit], Sum([MYTABLE]![UNITS_ORDERED])-Sum([MYTABLE]![ASN_QTY]) AS [Units Open], MYTABLE.PO_TYPE 
FROM MYTABLE 
WHERE (((MYTABLE.PO_TYPE) Like IIf([Forms]![frmMain]![ReplnExclude]=True,([MyTable].[TYPE])<>"REPLN","*")) AND ((MYTABLE.DPT_NUMBER)=[Forms]![frmMain]![DeptNum]) AND ((MYTABLE.GROUP_ID)="RP10") AND ((MYTABLE.PO_EXP_RCT_DATE) Between [Forms]![frmMain]![StartDate] And [Forms]![frmMain]![EndDate]) AND ((MYTABLE.PO_HDR_STATUS)<>"Cancelled") AND ((MYTABLE.PO_DTL_STATUS)<>"Cancelled")) 
GROUP BY MYTABLE.DPT_NUMBER, MYTABLE.VENDOR_ID, MYTABLE.VENDOR_NAME, MYTABLE.PO_TYPE 
ORDER BY MYTABLE.VENDOR_NAME;

在

where子句中你开始与“WHERE（（（MYTABLE.PO_TYPE）像”，但给你在找什么没有标准，然后做IIF语句把另一条款中，我去掉（ （（MYTABLE.PO_TYPE）如下面的语句

这里我们把AND放在语句中，因为我们只需要AND，如果它是真的，否则我们只需要一个空格来移动到下一个子句。

IIF（[表格]！[frmMain]！[ReplnExclude] =真，（[MyTable的]。[类型]）<> “REPLN AND”， “”））

如此充满

SELECT MYTABLE.DPT_NUMBER, MYTABLE.VENDOR_ID AS [Vendor ID], MYTABLE.VENDOR_NAME AS [Vendor Name], Sum(MYTABLE.UNITS_ORDERED) AS [Units Ordered], Sum(MYTABLE.RECEIVED_QTY) AS [Units Received], IIf(Sum([MYTABLE]![RECEIVED_QTY])=0,0,([Units Received]/[Units Ordered])) AS [Received Fill Rate], Sum(MYTABLE.ASN_QTY) AS [ASN Ship QTY], Sum([MYTABLE]![ASN_QTY])-Sum([MYTABLE]![RECEIVED_QTY]) AS [Units In Transit], Sum([MYTABLE]![ASN_QTY])/Sum([MYTABLE]![UNITS_ORDERED]) AS [Fill Rate with In Transit], Sum([MYTABLE]![UNITS_ORDERED])-Sum([MYTABLE]![ASN_QTY]) AS [Units Open], MYTABLE.PO_TYPE 
FROM MYTABLE 

WHERE IIf([Forms]![frmMain]![ReplnExclude]=True,([MyTable].[TYPE])<>"REPLN AND","")) ((MYTABLE.DPT_NUMBER)=[Forms]![frmMain]![DeptNum]) AND ((MYTABLE.GROUP_ID)="RP10") AND ((MYTABLE.PO_EXP_RCT_DATE) Between [Forms]![frmMain]![StartDate] And [Forms]![frmMain]![EndDate]) AND ((MYTABLE.PO_HDR_STATUS)<>"Cancelled") AND ((MYTABLE.PO_DTL_STATUS)<>"Cancelled")) 
GROUP BY MYTABLE.DPT_NUMBER, MYTABLE.VENDOR_ID, MYTABLE.VENDOR_NAME, MYTABLE.PO_TYPE 
ORDER BY MYTABLE.VENDOR_NAME
