问题描述
我在运行 sql server 存储过程时遇到问题.我使用动态sql.我收到错误必须声明标量变量@EmployeeId".
I am having problems running sql server stored procedure. I using a dynamic sql. I get the error "Must declare the scalar variable "@EmployeeId".
SQL 查询
ALTER PROCEDURE [dbo].[GetLeaveDays] -- Add the parameters for the stored
procedure here
@LeaveType varchar(5000),
@AdminId int,
@EmployeeId int
AS
BEGIN
SET NOCOUNT ON;
DECLARE
@queryString nvarchar(MAX);
SET @queryString = 'SELECT ' + @LeaveType + ' FROM CompulsoryLeave WHERE
AdminId = @AdminId AND Id=(SELECT LeaveStructureId FROM Employee WHERE
Id=@EmployeeId)';
EXECUTE sp_executesql @queryString,
N'@AdminId int',
N'@EmployeeId int',
@AdminId = @AdminId,
@EmployeeId=@EmployeeId
END
推荐答案
第二个 sp_executesql 参数应该是包含所有参数定义的单个字符串.试试:
The second sp_executesql parameter should be a single string with all parameter definitions. Try:
EXECUTE sp_executesql @queryString,
N'@AdminId int, @EmployeeId int',
@AdminId = @AdminId,
@EmployeeId = @EmployeeId;
