vb.net 中的事务计数异常（SQL 异常）

Question

当我要通过 sqlserver 的 StoredProceduer 在表中输入记录时，我遇到了异常 我有一个字段，我需要在表中插入新记录后立即更新。 为此，我创建了一个 sotredprocedure，其中我首先编写了插入命令，然后我为相同的记录编写了更新命令，但它给了我以下错误 SQL异常： EXECUTE 之后的事务计数表明 BEGIN 和 COMMIT 语句的数量不匹配。先前计数 = 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，例如：我刚刚在存储过程中编写了插入命令，并创建了一个 afterInsert 触发器，我在其中触发了更新命令。但我仍然面临上述异常

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,

Answer 1

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

您必须平衡您的 BEGIN TRAN 和 COMMIT/ROLLBACK，以便 @@TRANCOUNT 在相同范围内以相同的值开始和结束。

要么全部在存储过程中完成，要么全部在客户端完成

Answer 2

如果在您的 TRY 块中发现错误，在我看来您没有对打开的事务执行任何操作 - COMMIT 不会运行，但您的 CATCH 块没有 ROLLBACK。
