如何将访问查询转换为MS SQL

Posted 2021-04-01

我试图在MS SQL中运行访问查询但我不知道如何做我已经研究但无法找到任何解决方案。

这是Access Query（它在Access中正常工作）：

更新的代码：

SELECT DISTINCT b.Category, b.SubCategory1, b.SubCategory2, b.SubCategory3, 
b.SubCategory4, 'Total '+ b.SubCategory3+' FY 2018' AS Title, 
Sum(b.TotalAmount) AS Budget,

po.PONumber + ' - ' + po.Title + ' ('+ po.ProjectStatus +')' ), 0 AS Budget,

我在SQL Server中运行相同的查询，但我无法弄清楚问题，请帮助我。

任何帮助对我来说都很棒。

答案

1.

'201801'附近的语法不正确。

列名不能以数字开头：https://docs.microsoft.com/en-us/sql/relational-databases/databases/database-identifiers将它放在方括号中，如[2018]

2.

isnull函数需要2个参数。

ISNULL内部的IIF被打破了。您没有完成向其中任何一个的迁移。应该这样（服务器的额外努力，不受欢迎）：

IIF(
  (SELECT Sum(p.TotalOrdered) FROM tblPO AS p WHERE p.BudgetCategory=b.id),
  0,
  (SELECT Sum(p.TotalOrdered) FROM tblPO AS p WHERE p.BudgetCategory=b.id)
) AS UncommitedBudget

或这个：

ISNULL((SELECT Sum(p.TotalOrdered) FROM tblPO AS p WHERE p.BudgetCategory=b.id), 0)

3. DISTINCT之后的GROUP BY是荒谬的。它对输出没有影响，但仍需要服务器进行排序。或者你有逻辑上错误的GROUP BY条款。

你不能在陈述中间加分号;。在每个UNION ALL之前看到。

5.看看通常如何进行旋转：

SELECT p.[201801], p.[201802], p.[201803]
FROM 
( 
    SELECT CONVERT(VARCHAR(6), i.period, 112) period_name, i.amount
    FROM tblInvoices i
    WHERE i.period >= '20180101' and i.period < '20190101'
) i
pivot (
  sum(i.amount) 
  for i.period_name in (
    [201801], [201802], [201803]
  )
)p

避免这个：

...
(select sum(tb.InvoiceAmount) from tblInvoices AS tb WHERE 
Month(tb.AcctPeriod)=1 AND tb.PONumber=po.PONumber) AS 201801, 
(select sum(tb.InvoiceAmount) from tblInvoices AS tb WHERE 
Month(tb.AcctPeriod)=2 AND tb.PONumber=po.PONumber) AS 201802,
...

您的方法使服务器工作得更多。
