Question

我正在尝试编写一个查询，如果表单上的标志被关闭则返回所有结果，如果标志打开则排除特定值。我一直在搜索，但找不到我需要的确切语法。

当我在iif语句中有'Like'时（当它被评估为False时）没有返回任何结果。当我将Like移动到iif语句的外部时，我将在关闭复选框时获得预期的结果。如果打开标志，我无法获得任何结果。

有没有人知道我需要编写我的iif语句来获取所有值，如果标志被关闭，所有值只有“REPLN”，如果标志被打开？

ORDER BY MYTABLE.VENDOR_NAME;

Answer 1

在你的where子句中，你以'WHERE（（（MYTABLE.PO_TYPE）赞'开头，但没有给出你要找的内容的标准，然后用iif语句放入另一个子句。我删除了（（（MYTABLE。 PO_TYPE）喜欢下面的陈述。

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

IIf（[Forms]！[frmMain]！[ReplnExclude] = True，（[MyTable]。[TYPE]）＆lt;＆gt;“REPLN AND”，“”））

如此完整

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
