Question

我有一个存储过程，根据分类帐条目计算可用余额，如下所示。我想编辑并添加一个额外的参数;原始SP仅执行此查询：

SELECT SUM([amount value]) as [Bal available]  
FROM  [xxxxxxxxxxxx $Ledger Entries] 
WHERE [Entry No_] ='number_here'

但我希望它能实现：

SELECT SUM([amount value]) as [Bal available]  
FROM  [xxxxxxxxxxxx $Ledger Entries] 
WHERE [Transaction Type] ='TYPE1' and [Entry No_] ='number_here'`

有什么建议吗？

ALTER PROCEDURE [dbo].[loadbal] 
    (
    @Company_Name varchar(100),
    @EntNo varchar(100)
    )
AS
BEGIN
DECLARE @SQL VARCHAR(4000)
DECLARE @TableName VARCHAR(4000)

SET @TableName='['+@Company_Name+' $Ledger Entries]'

SELECT @SQL = ' SELECT SUM([amount value]) as [Bal available]  
                FROM '+@TableName+' WHERE [Entry No_] ='+@EntNo

EXEC (@SQL)

END

只需更改您的Select声明如下：

SELECT @SQL = ' SELECT SUM([amount value]) as [Bal available]  FROM '+@TableName+' WHERE [Transaction Type] = ''TYPE1'' AND [Entry No_] ='+@EntNo

SQL Query将如下所示：

 SELECT SUM([amount value]) as [Bal available]  FROM [ $Ledger Entries] WHERE [Transaction Type] = 'TYPE1' AND [Entry No_] = <whatever u have passed here>
