Update stored procedure using C#? - sql

Question

I have 10 database servers and most procedures are the same.
So I plan to make procedure distribute program.
For convenient application, I want to use "the procedure modify code made by tool" itself.
For example, when I click modify button of the procedure on SSMS the code is like below.
USE [DB]
GO
/****** Object: StoredProcedure [dbo].[HongTestProcedure] Script Date: 2020-08-28 오전 11:09:02 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: hong
-- Create date: 2020-03-07
-- =============================================
ALTER PROCEDURE [dbo].[HongTestProcedure]
-- Add the parameters for the stored procedure here
#ID varchar(10)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT *
FROM table
END
And then, if I want to modify the parameter of the procedure.
Maybe the code is like below:
USE [DB]
GO
/****** Object: StoredProcedure [dbo].[HongTestProcedure] Script Date: 2020-08-28 오전 11:09:02 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: hong
-- Create date: 2020-03-07
-- =============================================
ALTER PROCEDURE [dbo].[HongTestProcedure]
-- Add the parameters for the stored procedure here
#ID varchar(10)
#ID2 varchar(10) -- it is added.
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT *
FROM table
END
I consider that program has a textbox and button.
and I want to insert all above code.
maybe it looks like it:
So, I try the code like below:
public bool UpdateProcedure(string dbip, string query)
{
DataSet ds = new DataSet();
SqlConnection sqlConn = new SqlConnection("server = " + dbip + dbInfo);
sqlConn.Open();
SqlCommand sqlComm = new SqlCommand(query, sqlConn);
sqlComm.ExecuteNonQuery();
return true;
}
If it run successfully, I will run query on 10 database servers.
But it return error message. even it can be run in SSMS.
incorrect syntax near 'GO'
CREATE/ALTER PROCEDURE must be the first statement in a query batch
Can I solve it?

Yes. Since you can construct it as an Dynamic SQL in C# and Open an SQL Connection and pass the Dynamic SQL to EXEC sp_executesql #DynamicSQL. This will create the required SP in the required Database.
