Question

我正在处理存储过程以将项目添加到我的数据库。该过程还处理编辑项目。代码一直在跳过insert语句，即使在我的测试运行中我声明Id = 0应该启动Post而不是Put。有人可以指出我的代码中哪里出错了吗？

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

    /*--------------------------------------------------------------------------
    INSERT
    --------------------------------------------------------------------------*/
    IF(@NeedId = 0)
        BEGIN
            INSERT INTO [dbo].[CustomerNeeds]
                       ([PersonId]

Answer 1

我想知道你的DELETE部分是否引用了错误的表格？

就目前而言，我相信你只需删除刚刚插入的行。

代码正在跳过Insert Statement
