Question

I want to insert a value by using stored procedure in mssql. This is my stored procedure :

ALTER PROCEDURE dbo.insertNewMember 
(@name varchar(30), 
@age int )
AS
BEGIN 
    INSERT INTO member(memId, name, age) VALUES ('', @name, @age);
END 

My C# code, to use this procedure:

addStaffSql.InsertCommand = "insertNewMember";
addStaffSql.InsertCommandType = SqlDataSourceCommandType.StoredProcedure;
addStaffSql.InsertParameters.Add("@name", name);
addStaffSql.InsertParameters.Add("@age", age);
addStaffSql.Insert();

But I got the following error when I run the program:

Procedure or function 'insertNewMember' expects parameter '@name', which was not supplied.

If you have got any idea, I will appreciate.

Answer 1

Try losing the “@” symbol in the Add() methods.

addStaffSql.InsertCommand = "insertNewMember";
addStaffSql.InsertCommandType = SqlDataSourceCommandType.StoredProcedure;
addStaffSql.InsertParameters.Add("name", name);
addStaffSql.InsertParameters.Add("age", age);
addStaffSql.Insert();
