Altering a SQL View from C#, Ado.Net

I am getting error - ALTER VIEW must be the first statement in a query batch.

Thanks for responses. Hi Azarudeen , i had tried one the same option which you provided. but getting incorrect syntax near view.

Please let me know if you have any other thoughts.

Do you understand about view in SQL Server?
You are about changing DDL and I guess you need DML.

Do not changing the View on the fly if you not need it, it will causing impact on another users.

This is the view.

create view vw_employeesbyId as select ename,location,email from dbo.employees 

This is your DML:

select * from vw_employeesbyId where empid = @empid 

Why you need to re-create view? when you need to get data by EmpId?

Hi Srini 

Try this 

• Connect to the SQL Server database using a SqlConnection object.
• Create a SqlCommand object with the ALTER VIEW statement to modify the view.
• Set any necessary parameters in the SqlCommand object if you need to pass dynamic values.
• Execute the ALTER VIEW statement using the ExecuteNonQuery method of the SqlCommand object.
• Close the SqlConnection object once you're done.

• using (SqlConnection connection = new SqlConnection(connectionString))
  {
      connection.Open();
      
      string alterViewSql = "ALTER VIEW vw_employeesbyId AS SELECT ename, location, email FROM dbo.employees WHERE empid = @empid";
      
      using (SqlCommand command = new SqlCommand(alterViewSql, connection))
      {
          command.Parameters.AddWithValue("@empid", empId); // Set the parameter value if required
          
          command.ExecuteNonQuery(); // Execute the ALTER VIEW statement
      }
      
      connection.Close();
  }
  

  Dont forget to replace the connection strings, Hope this helps
