c# - 我如何从 C# 运行 sql server 触发器

Question

我在单个 sqlserver 表中有多个触发器，有些通过连接不同的字段来创建产品描述，有些从另一个表获取数据，还有一个触发器将产品插入另一个表。

我想运行触发器，在从 C# 中单击按钮时将数据插入另一个数据库表。

这是我的代码，用于将产品插入或设置到另一个表中

Create  TRIGGER [dbo].[WHL-MISYSSETUP] 
    ON [dbo].[WHEELS]
    AFTER insert,UPDATE
    AS 
    BEGIN
     IF TRIGGER_NESTLEVEL() > 1
     RETURN

我想手动或在按钮单击事件上运行它的主要原因是由于某种原因这个触发器在计算字段和一些触发器之前运行所以我没有得到完整的信息插入到另一个表中插入或更新后的第一次。我试过了同样的问题

当创建或更新新产品时，我想在按钮 click_event 上从 C# 运行它。任何想法将不胜感激

Answer 1

无法调用触发器。在您的情况下，它们应该自动触发每一行: 插入后，更新。

如果您需要在单击某个按钮后运行此查询，我建议您不要使用触发器，而是创建一个新的存储过程。 这里的问题是，您必须在不使用插入表的情况下知道需要更新的 [STOCK NO] 是什么。
