Exception vb.net中的事务计数异常（SQL异常）

当我要通过sqlserver的StoredProceduer在表中输入记录时，出现以下异常 在表中插入新记录后，我需要立即更新一个字段。 为此，我创建了一个sotredprocedure，在该过程中，我首先编写了insert命令，然后为相同的RECORD编写了update命令，但它给出了以下错误 SQlException: EXECUTE后的事务计数表示BEGIN和COMMIT语句的数量不匹配。上一次计数=1，当前计数=2。在批处理结束时检测到不可提交的事务。事务被回滚。存储过程执行中的一些错误

我还尝试了另一种方式：我只是在storedprocedure中编写了insert命令，并创建了一个afterInsert触发器，在该触发器中触发update命令。但我仍然面临着上述例外

详情： 表结构：

CREATE TABLE [dbo].[TabStoreGRNMaster](
    [pk_grnm_id] [bigint] IDENTITY(1,1) NOT NULL,
    [fk_col_id] [bigint] NULL,
    [fk_sup_id] [bigint] NULL,
    [grnm_grnno] [varchar](50) NULL,
    [grnm_date] [nvarchar](10) NULL,
    [grnm_partyinvno] [varchar](50) NULL,
    [grnm_invdate] [nvarchar](10) NULL,
    [grnm_freight] [numeric](7, 2) NULL,
    [grnm_otherchrg] [numeric](7, 2) NULL,
    [grnm_roundoff] [bit] NULL,
    [Fk_User_Id] [bigint] NULL,
    [grnm_EntryDate] [nvarchar](8) NULL,

在我看来，如果在TRY块中发现错误，您似乎没有对打开的事务执行任何操作-COMMIT不会运行，但是CATCH块没有回滚。

您对另一个答案的评论提到“调用此存储过程时，我也在维护Vb.net中的事务”。这就是原因

您必须平衡BEGIN TRAN和提交/回滚，以便@TRANCOUNT在同一范围内以相同的值开始和结束

要么在存储过程中全部执行，要么在客户机中全部执行

调用此存储过程时，我还要从Vb.net维护事务
