call stored procedure with parameter in entity framework core 6

 

To call a stored procedure with parameters in Entity Framework Core 6, you can use the FromSqlRaw or FromSqlInterpolated methods, passing the parameters as arguments. Here's an example of how you can call a stored procedure with parameters:

Assuming you have a stored procedure named GetUsersByAge that takes an @age parameter and retrieves a list of users based on their age, and you have a User class representing your users:

csharp
public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    // other properties
}

Here's how you can call the GetUsersByAge stored procedure with a parameter in Entity Framework Core 6:

csharp
public List<User> GetUsersByAgeFromStoredProcedure(int age) 
{ 
using (var context = new YourDbContext())
    {
        var users = context.Users
            .FromSqlRaw("EXEC GetUsersByAge @age", new SqlParameter("@age", age))
            .ToList();
        return users; 
 } 
}

In this example, YourDbContext represents your Entity Framework Core DbContext class. The FromSqlRaw method is used to execute the raw SQL query, and the SqlParameter class is used to pass the @age parameter to the stored procedure.

You can also use the FromSqlInterpolated method for interpolated SQL strings with parameters:

csharp
public List<User> GetUsersByAgeFromStoredProcedure(int age)
{
    using (var context = new YourDbContext())
    {
        var users = context.Users
            .FromSqlInterpolated($"EXEC GetUsersByAge {age}")
            .ToList();
        return users;
    }
}

In this case, the @age parameter is interpolated into the SQL string.

Ensure that you replace YourDbContext with the actual name of your DbContext class, and that your stored procedure is correctly defined in your database, expecting the @age parameter.
