Question

我想通过名称检索所有信息以及金额总和，因此我将此查询用于此目的。

select SUM(Amount)as total,RecieptNo,Name,UniqueId,Date,Amount,LateFee,Other from Amount where Name='Shaikh'

但发生此错误。专栏＆＃39; Amount.RecieptNo＆＃39;在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。所以请帮助我。

Answer 1

Select RecieptNo, Name
    , UniqueId, Date
    , Amount
    , LateFee, Other 
    , ( Select Sum( A1.Amount )
        From Amount As A1
        Where A1.Name = A.Name ) As Total
From Amount As A
Where Name='Shaikh'

SQL Server 2005 +中提供的另一种选择：

Select RecieptNo, Name
    , UniqueId, Date
    , Amount
    , LateFee, Other 
    , Sum( Amount ) Over( Partition By Name ) As Total
From Amount As A
Where Name='Shaikh'

Answer 2

使用SUM（）等聚合SQL函数时，必须使用GROUP BY子句。下面的例子证明了这一点。但这可能不是解决查询的最理想方法。我所做的是添加一个group by子句，其中包括除SUM之外选择的所有列。例如：

    select RecieptNo, Total, UniqueId, Date, Amount, LateFee, Other SUM(Amount)as total  from 
Amount where Name='Shaikh' group by RecieptNo, Total, UniqueId, Date, Amount, LateFee, Other

Answer 3

select SUM(Amount)as total,RecieptNo,Name,UniqueId,Date,Amount,LateFee,Other from Amount
group by RecieptNo,Name,UniqueId,Date,Amount,LateFee,Other having Name='Shaikh'

Answer 4

您需要分组

select SUM(Amount)as total,Name from Amount where Name='Shaikh' group by Name

如果您想在选择列表中添加其他内容，则需要在group by子句中添加此字段，否则会出错

如何编写此查询？
