如何合并这两个 Access Sql 查询答案

【问题标题】：How Can I merge these two Access Sql queries如何合并这两个 Access Sql 查询
【发布时间】：2015-06-29 16:06:19
【问题描述】：

我想将这两个查询合并为一个查询。这是代码。两者都是一张表，但您会看到来自不同部分的不同数据。我只想用一个查询记录一条记录。

> DoCmd.RunSQL "insert into Report (id, [date], namep , [NEXTC],
> [Nurse])" & _ " values (" & Chr(34) & x & Chr(34) & " ," & Chr(34) & b
> & Chr(34) & "," & "5," & _ " " & Chr(34) & c & Chr(34) & ", " &
> Chr(34) & n & Chr(34) & ")"

还有这个

DoCmd.RunSQL "INSERT INTO Report ( brand, Bag, Acc, Id , NameP)" & _
"Select Top 1 * from" & _
    "(SELECT TOP 1 Brand FROM (SELECT * FROM Report WHERE ID=" & _
    x & _
    ") WHERE Brand IS NOT NULL ORDER BY date DESC Union All SELECT top 1 null FROM report WHERE Brand IS NULL) AS Brand," & _
    "(SELECT TOP 1 Bag FROM (SELECT * FROM Report WHERE ID=" & _
    x & _
    ") WHERE Bag IS NOT NULL ORDER BY date DESC Union All SELECT top 1 null FROM report WHERE Bag IS NULL) AS Bag," & _
    "(SELECT TOP 1 ACC FROM (SELECT * FROM Report WHERE ID=" & _
    x & _
    ") WHERE ACC IS NOT NULL ORDER BY date DESC Union All SELECT top 1 null FROM report WHERE ACC IS NULL) AS ACC," & _
 "(SELECT TOP 1 ID FROM Report WHERE ID=" & _
 x & _
 ") AS ID," & _
 "( SELECT TOP 1 NameP FROM Report WHERE ID=" & _
 x & _
 ") as NameP;"

【问题讨论】：

它不允许我这样做INSERT INTO Report ( brand, Bag, Acc, Id) Select Top 1 * from ((SELECT TOP 1 Brand FROM (SELECT Brand,date FROM Report WHERE ID= x) WHERE Brand IS NOT NULL), '','',5022)
你能展示一些示例数据吗？您的问题无法理解。

【解决方案1】：

测试一下，它应该可以工作（可能有些括号是错误的，使用前检查一下）：

DoCmd.RunSQL "insert into Report (id, [date], namep , [NEXTC], [Nurse], brand, Bag, Acc, Id , NameP)" & _
" values (" & Chr(34) & x & Chr(34) & " ," & Chr(34) & b & Chr(34) & "," & "5," & _
" " & Chr(34) & c & Chr(34) & ", " & Chr(34) & n & Chr(34) & ", " & _
"(SELECT TOP 1 Brand FROM (SELECT * FROM Report WHERE ID=" & x & _
") WHERE Brand IS NOT NULL ORDER BY date DESC Union All SELECT top 1 null FROM report WHERE Brand IS NULL) AS Brand " & ", " & _
"(SELECT TOP 1 Bag FROM (SELECT * FROM Report WHERE ID=" & x & _
") WHERE Bag IS NOT NULL ORDER BY date DESC Union All SELECT top 1 null FROM report WHERE Bag IS NULL) AS Bag " & ", " & _
"(SELECT TOP 1 ACC FROM (SELECT * FROM Report WHERE ID=" & x & _
") WHERE ACC IS NOT NULL ORDER BY date DESC Union All SELECT top 1 null FROM report WHERE ACC IS NULL) AS ACC " & ", " & _
"(SELECT TOP 1 ID FROM Report WHERE ID=" & x & ") AS ID," & _
 "( SELECT TOP 1 NameP FROM Report WHERE ID=" & x & ") as NameP )"

【解决方案2】：

您的查询不清楚，但您的查询应该是这样的：

INSERT INTO Report (id, [date], namep , [NEXTC], [Nurse], brand, Bag, Acc, Id , NameP)
SELECT TOP 1 'value1', 'value2', ..., FROM yourTable ...

使用INSERT INTO SELECT

value1, value2 可以是统计数据，但您也可以从yourtable 获得一些价值

【讨论】：

它说这个操作在子查询中是不允许的！
您应该查看您的查询。如果您想从SELECT 语句中使用INSERT，可以使用INSERT INTO SELECT。
如果你检查第二个查询它是用 select 插入的，我已经使用它
access sql查询中可以使用变量吗？
你可以。 SELECT 'a', a FROM table。第一个 a 是实际 a 但第二个 a 来自表
