如何使用动态参数执行 Sp

Question

我创建了一个存储过程，通过提供员工的收入来查找姓名和职务

Create  PROCEDURE GetEmployeessalaryInOutputVariable
(
    @Income INT,                 -- Input parameter,  Income of the Employee
    @FirstName VARCHAR (30) OUT, -- Output parameter to collect the Employee name
    @Title VARCHAR (30)OUT       -- Output Parameter to collect the Employee designation
)
AS
BEGIN
SELECT FirstName=@FirstName, Title=@Title 
    FROM Salaries WHERE @Income=Income
END

在此之后，我尝试按如下方式执行 Sp

Declare @FirstName as varchar(30) -- Declaring the variable to collect the Employeename
Declare @Title as varchar(30)     -- Declaring the variable to collect the Designation
Execute GetEmployeessalaryInOutputVariable 500 , @FirstName output, @Title output
select @FirstName,@Title as Designation   

上面的语句一写就报错

Invalid object name GetEmployeessalaryInOutputVariable

为什么程序已经创建并存在，但它的行为是这样的？

另外，如何运行查询以获得正确的结果？

Answer 1

Execute GetEmployeessalaryInOutputVariable 500 , 'FirstName', 'Title'

或

Declare @FirstName as varchar(30)
set @FirstName = 'FirstName'
Declare @Title as varchar(30)   
set @Title = 'title'
Execute GetEmployeessalaryInOutputVariable 500 , @FirstName, @Title 

Answer 2

Create  PROCEDURE GetEmployeessalaryInOutputVariable
(
    @Income INT,                 -- Input parameter,  Income of the Employee
    @FirstName VARCHAR (30) OUT, -- Output parameter to collect the Employee name
    @Title VARCHAR (30)OUT       -- Output Parameter to collect the Employee designation
)
AS
BEGIN
SELECT @FirstName = FirstName, @Title=Title 
    FROM Salaries WHERE @Income=Income
END

你的SP应该是这样的
