Sql 代码正在跳过Insert语句

我正在处理一个存储过程，以便将一个项添加到数据库中。该过程还处理编辑项目的操作。代码一直跳过insert语句，即使在我的测试运行中我声明Id=0，它应该启动Post而不是Put。有人能指出我的代码哪里出错了吗

DECLARE @PersonId INT,
    @Description VARCHAR(300),
    @ModifiedById INT,
    @NeedId INT

SET @PersonId = 11
SET @Description = 'Testing again'
SET @ModifiedById = 1


BEGIN
--SET NOCOUNT ON;
--SET XACT_ABORT ON;

DECLARE @TimeStamp DATETIME

SET @TimeStamp = GETUTCDATE()

BEGIN TRY
    BEGIN TRANSACTION

    /*--------------------------------------------------------------------------

    IF(@NeedId = 0)
        BEGIN

我想知道您是否在删除部分引用了错误的表

---

就目前情况而言，我相信您只需删除刚刚插入的行。

嗯，您什么时候为@NeedId设置过值？这不是未初始化的整数等于0的VBScript。它是作为0从前端传入的。当它在进程中被设置为0时，没有任何区别。您应该确认这一点。另外，如果这个代码在一个过程中，你应该显示那个代码，而不是这个代码，它没有前端供我们测试。你需要NeeID和PersonID吗？你可以使用PRINT添加一些日志，你会看到是否执行了INSERT。正如答案所说，该记录在插入后被删除，因此没有发生任何事情。
