如何在C#中编写下面的存储过程

我正在创建类库文件。我遇到了一种情况....不要将脚本文件提供给客户...所以我必须在 C# 代码中创建 SP。我非常想把它保存在 C# 程序集中让我知道这可能吗

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[AdjustTax]') AND type in (N'P', N'PC'))

DROP PROCEDURE [dbo].[AdjustTax]

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO
CREATE PROCEDURE [dbo].[AdjustTax]

    @IN_SOPNo         VARCHAR(21),

    @O_iError         INT OUTPUT

为什么首先要用 C# 编写它？

如果要管理 DB 架构，请使用Visual Studio 数据库项目。

如果您非常想将其保留在 C# 程序集中，请创建一个单独的 .sql 文件，将其作为资源嵌入，然后将其作为字符串加载到 C# 中。

在文件属性中将Build Action更改为Embedded Resource并使用以下代码加载它

using (Stream stream = Assembly.GetExecutingAssembly()
                               .GetManifestResourceStream("Your assembly namespace" + "file.sql"))
using (StreamReader reader = new StreamReader(stream))
{
    string result = reader.ReadToEnd();
}

300行SP就可以了，只要清晰易懂

对于大部分 SP 最好写一些评论
