C# 事务计数与分层事务不匹配

我有一组存储过程，它们各自都是一个事务，我需要作为事务运行。我使用事务范围对象作为其全部或无任务。在第一个ExecuteOnQuery运行之后，我在EXECUTE之后获得SQLException事务计数，这表明BEGIN和COMMIT语句的数量不匹配。上一次计数=1，当前计数=0。运行过程而不将其包装在事务作用域中可以很好地工作，并且我没有遇到上面的错误，但是我需要确保所有过程都运行到完成时没有错误，或者所有过程都需要回滚

其他三个存储过程遵循相同的事务结构。

存储过程中缺少BEGIN事务。

不能有子事务。。。sql server中的sorrynested事务是一个神话。文档中确实讨论了它们，但它们并没有做您认为应该做的事情。如果您开始第二个事务，唯一实际发生的事情就是它增加了@trancount。任何回滚操作都将回滚事务并将@trancount重置为0.Darn。好的，我想我必须将这些过程变成一个巨大的过程/事务。您使用命名事务、未命名事务还是两者的组合？两者混合会导致问题。。。
