我需要获取受存储过程影响的记录数。基于此值，我想更新用户操作是否已完成。
但我的 OUTPUT@RecordsAffected参数始终为 0
如何获取事务中插入的记录数？
已关注如何获取受存储过程影响的记录数？和http://rusanu.com/2009/06/11/exception-handling-and-nested-transactions/
这是我的程序
ALTER PROCEDURE [dbo].[SaveRoleFeatures]
(
@RoleId INT,
@SelectedFeatures AS IdInt READONLY,
@RecordsAffected INT OUTPUT
)
AS
BEGIN
set nocount on;
DECLARE @ErrorCode int
SELECT @ErrorCode = @@ERROR
declare @trancount int;
set @trancount = @@trancount;
BEGIN TRY
BEGIN TRAN
DELETE FROM RoleXFeature WHERE RoleIid= @RoleId
INSERT RoleXFeature
(
RoleIid,
FeatureId,
IsDeleted
)
SELECT
@RoleId,
Id,
0
FROM @SelectedFeatures
COMMIT TRAN
SET @RecordsAffected = @@ROWCOUNT
END TRY
BEGIN CATCH
declare @error int, @message varchar(4000), @xstate int;
select @error = ERROR_NUMBER(),
@message = ERROR_MESSAGE(), @xstate = XACT_STATE();
if @xstate = -1
rollback;
if @xstate = 1 and @trancount = 0
rollback
if @xstate = 1 and @trancount > 0
rollback transaction SaveRoleFeatures;
raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
return;
END CATCH
END
