您好，这是我编写的第一个光标程序。
在成功影响我想要使用此过程执行的过程中的表行后，我很惊讶地看到错误。
我正在将菜单分配给帖子，当我从特定帖子中删除某些菜单时，我需要为属于该帖子的所有员工更新（添加/删除）菜单。下面的过程可以做所有事情，但我收到一个错误：
错误：数据库中已有一个名为“EmployeeMenuMst”的对象。
执行后。
存储过程是：
ALTER PROCEDURE [sUpdateEmpMenuMst]
(@EmployeePostID INT)
AS
BEGIN
SET NOCOUNT ON;
DECLARE @EMPID INT
DECLARE @EMPMENUID INT
BEGIN TRAN
BEGIN TRY
DECLARE EmployeeTable CURSOR FOR
SELECT EmployeeID FROM EMPLOYEEMST WHERE EmployeePostID=@EmployeePostID
OPEN EmployeeTable
FETCH NEXT FROM EmployeeTable INTO @EMPID
WHILE @@FETCH_STATUS = 0
BEGIN
DELETE FROM EmployeeMenuMst WHERE EmployeeID=@EMPID
FETCH NEXT FROM EmployeeTable INTO @EMPID
END
CLOSE EmployeeTable
DEALLOCATE EmployeeTable
SELECT EmployeeMst.EmployeeID, EmployeePostMenuMst.MenuID, EmployeePostMenuMst.AccessLevelID,1 AS ISVISIBLE
INTO EmployeeMenuMst
FROM EmployeePostMenuMst
INNER JOIN EmployeeMst
ON EmployeePostMenuMst.EmployeePostID = EmployeeMst.EmployeePostID
WHERE EmployeeMst.EMPLOYEEPOSTID=@EmployeePostID ORDER BY EmployeeMst.EMPLOYEEID
COMMIT TRAN
END TRY
BEGIN CATCH
ROLLBACK TRAN
IF @@TRANCOUNT > 0
DECLARE @ErrMsg nvarchar(4000), @ErrSeverity INT
SELECT @ErrMsg = ERROR_MESSAGE(),
@ErrSeverity = ERROR_SEVERITY()
RAISERROR(@ErrMsg, @ErrSeverity, 1)
END CATCH
END
GO
在aspx.cs文件后面的代码中：
private void UpdateMenus()
{
SqlCommand cmd = new SqlCommand();
SqlConnection con = new SqlConnection(conStr);
try
{
con.Open();
cmd.CommandText = "sUpdateEmpMenuMst";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@EmployeePostID", Convert.ToInt32(Session["postID"]));
cmd.Connection = con;
int i = cmd.ExecuteNonQuery();
}
catch (Exception ex)
{
con.Close();
}
finally
{
con.Close();
}
}
错误ExecuteNonQuery在线。为什么它会引发错误 - 任何想法？
在得到错误行之后，我需要的方式成功地受到影响！
