需要包含两个值的参数有问题

Question

我遇到了这个问题，我认为它与参数有关。我不确定我是否做得正确，但我 90% 确定查询中的参数不正确。所以，有两种形式（短格式和长格式）。

• 短格式就是短格式
• 长格式包括短格式和长格式一起

这是我的查询

WHERE  pid_respiratorfit.Id = @respfitID AND dimDocSectionLayout.sectionID = @sectionID
ORDER BY dimDocSectionLayout.[order], 
         dimDocInputLayout.[order];

如果记录只有简表，并且部分 ID 的参数将寻找值“1”，则表格将被成功打印。但是，如果记录具有长格式（也包括短格式）并且那是我现在遇到的问题，则部分 ID 将同时查找值“1”和“2”。但是到目前为止，我不知道如何添加包含短格式和长格式的参数并单独保留短格式值。

我不确定我是否理解你的问题，所以我会提供一个简化版本，如果我错了，你可以澄清一下。

我认为您有一个包含问题列表的表格，每个问题都标有“表格”，短或长，我将分别表示为 1 和 2。每个问题都有一个应该打印的“顺序”，问题的一些文本，以及一系列其他细节，这些细节不影响选择。您传入一个参数，说明您想要短格式还是长格式，其中 Short 是所有标记为“1”的问题，Long 是所有标记为 2 以及所有标记为 1 的问题。

如果这是您问题的本质，有几个选项会起作用，最好的选择取决于您的具体情况

--This is your parameter, could be passed into a Stored Procedure or whatever
DECLARE @FormLen INT = 1 --1 = ShortForm, 2 = LongForm

;with cteSampleData as (--Build some sample data
    SELECT * FROM (VALUES ('Taking medicine', 1, 1) 
        , ('Used Respirator', 2, 1), ('Lost vision', 3, 1), ('Back Injury', 4, 1)
        , ('High altitude', 5, 2), ('Harsh chemicals', 6, 2), ('Side jobs', 7, 2)
    ) as FormDef(QuestionText, QOrder, TargetForm)
)SELECT * 
FROM cteSampleData
WHERE (TargetForm = @FormLen --Grab line when @FormLen = 1 and TargetForm = 1 
        --or @FormLen = 2 and TargetForm = 2 
    OR (@FormLen = 2 AND TargetForm = 1)) --Grab line when @FormLen = 2 AND TargetForm = 1, 
        -- adding in Short Form questions when LongForm is specified
    -- AND (other conditions, like CustomerID = @Customer) --Use to add in other requirements, note that the above
        --MUST be in parenthesis!
--ALTERNATE FORM
--WHERE TargetForm <= @FormLen
ORDER BY QOrder, TargetForm

如果您可以用整数表示 TargetForm，并且您希望较长的表单包含所有“较短”的表单，那么最好的选择是

WHERE TargetForm <= @FormLen

form，如果以后定义更多的深度层，它很简单，很容易缩放。

如果您必须使用非整数表示，则最好使用 OR 格式

WHERE (TargetForm = @FormLen --Grab line when @FormLen = 1 and TargetForm = 1 
        --or @FormLen = 2 and TargetForm = 2 
    OR (@FormLen = 2 AND TargetForm = 1)) --Grab line when @FormLen = 2 AND TargetForm = 1, 

它也不能缩放，但对 TargetForm 的表示不敏感
