Question

这是我的存储过程。它需要INT作为输入，它本质上是一个员工ID。

old = {width=1920, x=5, y=831}, new = {width=1517, x=5, y=693}

我想要相同的行为但不需要手动提供输入。我希望它能够从staff表中获取所有现有的staffId，其中staffdd仍然是唯一的参数。我怎么做？我尝试过使用WHILE循环。但它

CREATE PROCEDURE [dbo].[spMonthlyPayroll]
@StaffId int
AS
BEGIN
    SET NOCOUNT ON;
    SELECT        StaffId, Name, CNICNumber, Salary, BankAccountNumber,[dbo].[totalWorkingDaysScalar](StaffId, datename(month, GETDATE())) as TotalDaysWorked, [dbo].[totalDaysWorkedScalar](StaffId, datename(month, GETDATE())) as TotalDaysWorked,
    (CONVERT([date],getdate())) AS PayrollDate,
    (CONVERT([date],dateadd(month,(-1),dateadd(month,datediff(month,(0),getdate())+(1),(0))))) AS PayrollFrom,
    (CONVERT([date],dateadd(day,(-1),dateadd(month,datediff(month,(0),getdate())+(1),(0))))) AS PayrollTo,
    (datename(month,getdate())) + ', ' + (datename(year,getdate())) AS PayrollPeriod,
    (Salary/[dbo].[totalWorkingDaysScalar](StaffId, datename(month,getdate()))) * [dbo].[totalDaysWorkedScalar](StaffId, datename(month,getdate())) as GrossSalary,
              .10 as IncomeTaxFactor,
              ((Salary/[dbo].[totalWorkingDaysScalar](StaffId, datename(month,getdate()))) * [dbo].[totalDaysWorkedScalar](StaffId, datename(month,getdate()))) - ((Salary/[dbo].[totalWorkingDaysScalar](StaffId, datename(month,getdate()))) * [dbo].[totalDaysWorkedScalar](StaffId, datename(month,getdate())) * (.10)) as TotalNetSalary

FROM            Staff
where Staff.StaffId=@StaffId
END


GO

在set @StaffId = select Staff.StaffId from Staff

请帮忙。我正在使用SQL Server 2014。

如果您希望每次都返回Staff表中的所有记录，并且您希望每次执行完全相同的查询，那么您根本不需要任何功能，只需创建观点：

CREATE VIEW dbo.CurrentMonthPayroll
AS
    SELECT  StaffId, 
            Name, 
            CNICNumber, 
            Salary, 
            BankAccountNumber,
            [dbo].[totalWorkingDaysScalar](StaffId, DATENAME(MONTH, GETDATE())) AS TotalWorkingDays, 
            [dbo].[totalDaysWorkedScalar](StaffId, DATENAME(MONTH, GETDATE())) AS TotalDaysWorked,
            (CONVERT(DATE,GETDATE())) AS PayrollDate,
            (CONVERT(DATE,DATEADD(MONTH,(-1),DATEADD(MONTH,DATEDIFF(MONTH,(0),GETDATE())+(1),(0))))) AS PayrollFrom,
            (CONVERT(DATE,DATEADD(DAY,(-1),DATEADD(MONTH,DATEDIFF(MONTH,(0),GETDATE())+(1),(0))))) AS PayrollTo,
            (DATENAME(MONTH,GETDATE())) + ', ' + (DATENAME(YEAR,GETDATE())) AS PayrollPeriod,
            (Salary/[dbo].[totalWorkingDaysScalar](StaffId, DATENAME(MONTH,GETDATE()))) * [dbo].[totalDaysWorkedScalar](StaffId, DATENAME(MONTH,GETDATE())) AS GrossSalary,
            .10 AS IncomeTaxFactor,
            ((Salary/[dbo].[totalWorkingDaysScalar](StaffId, DATENAME(MONTH,GETDATE()))) * [dbo].[totalDaysWorkedScalar](StaffId, DATENAME(MONTH,GETDATE()))) - ((Salary/[dbo].[totalWorkingDaysScalar](StaffId, DATENAME(MONTH,GETDATE()))) * [dbo].[totalDaysWorkedScalar](StaffId, DATENAME(MONTH,GETDATE())) * (.10)) AS TotalNetSalary
    FROM Staff
GO

如果您想将这些记录INSERT放到其他表中，您可以：

INSERT INTO PayrollTable
SELECT StaffId,
Name,
CNICNumber,
Salary,
BankAccountNumber,
TotalWorkingDays,
TotalDaysWorked,
PayrollDate,
PayrollFrom,
PayrollTo,
PayrollPeriod,
GrossSalary,
IncomeTaxFactor,
TotalNetSalary
FROM dbo.CurrentMonthPayroll

Answer 2

我认为用循环处理每个员工的表现并不好。

您可以修改存储过程以支持处理多个人员例如，您可以将参数@staffID更改为varchar变量，以获取带有分隔符的combin multliple staffid字符串

FROM   Staff
where Staff.StaffId=isnull(@StaffIds,Staff.StaffId)  --NULL is process all data
      or case when @StaffIds is null then 1 else 
charindex(','+convert(varchar,Staff.StaffId)+',',','+@StaffIds+',') end >0

将循环作为参数传递给存储过程
