Asp.net 加入2个select查询，与记录数无关

我有两张桌子

table 1                               table 2
------------------                   ----------------------
description   paidamt                description recievedamt
ele. bill     200                    donation    1000
stationary    500                    fees        200
salary        1000                   

我想要以下格式的结果（数据将根据日期排序）

问题是，当我将金额设置为借方时，我不能将贷方列设置为空，或者当我将金额设置为相应列的贷方时，我不能将借方列设置为空。我正在进行以下查询

WHEN Payment_Voucher_Master.grand_tot <> '0' 
  THEN '' 
  ELSE 'dgf'
END credit 
FROM Receipt_Voucher_Master,Payment_Voucher_Master
GROUP BY Payment_Voucher_Master.PaidTo,Payment_Voucher_Master.grand_tot

SELECT Receipt_Voucher_Master.PaidTo 
    AS description, Receipt_Voucher_Master.grand_total as credit,
CASE 
WHEN Receipt_Voucher_Master.grand_total <> '0'
  THEN '' 
  ELSE 'dgf'
END debit 
FROM Receipt_Voucher_Master,Payment_Voucher_Master
GROUP BY Receipt_Voucher_Master.PaidTo,Receipt_Voucher_Master.grand_total;

付款\u凭证\u Master.grand\u总计“0”时
然后“
其他“dgf”
终止信用
从收据凭证主控台、付款凭证主控台
按付款凭证主数据集分组。付款凭证主数据集。总数据集
选择收据\u凭证\u主文件.PaidTo
如说明所示，收据、凭证、主记录、总计作为贷方，
案例
当收据\u凭证\u主数据\u总计“0”时
然后“
其他“dgf”
结束借方
从收据凭证主控台、付款凭证主控台
按收据、凭证、主数据、付款到、收据、凭证、主数据、总计分组；

我正在尝试加入这两个查询

这应该适合您

SELECT 
    COALESCE(a.[description],b.[description]) AS [description],
    ISNULL(a.[paidamt],'') AS debit, 
    ISNULL(b.[recievedamt],'') AS credit
FROM [table1] AS a
FULL OUTER JOIN [table2] AS b
    ON a.[description] = b.[description]

SELECT 
    COALESCE(a.[description],b.[description]) AS [description],
    ISNULL(a.[paidamt],'') AS debit, 
    ISNULL(b.[recievedamt],'') AS credit
FROM [table1] AS a
FULL OUTER JOIN [table2] AS b
    ON a.[description] = b.[description]

declare @table1 table (
[description] varchar(20),
paidamt money
)

declare @table2 table (
