INSERT using LIST into Stored Procedure

Question

I have this stored procedure:

CREATE PROCEDURE [RSLinxMonitoring].[InsertFeatures] 
   @Features nvarchar(50), 
   @TotalLicenses int, 
   @LicensesUsed int,         


        

Answer 1

You should use Table type parameters.

create a class and Table type in sql server. Names and order should match. Now just convert your list to Table using the following code and pass it as a paremeter to the procedure.

    public static DataTable ToDataTable(this List iList)
    {
        DataTable dataTable = new DataTable();
        PropertyDescriptorCollection propertyDescriptorCollection =
            TypeDescriptor.GetProperties(typeof(T));
        for (int i = 0; i < propertyDescriptorCollection.Count; i++)
        {
            PropertyDescriptor propertyDescriptor = propertyDescriptorCollection[i];
            Type type = propertyDescriptor.PropertyType;

            if (type.IsGenericType && type.GetGenericTypeDefinition() == typeof(Nullable<>))
                type = Nullable.GetUnderlyingType(type);


            dataTable.Columns.Add(propertyDescriptor.Name, type);
        }
        object[] values = new object[propertyDescriptorCollection.Count];
        foreach (T iListItem in iList)
        {
            for (int i = 0; i < values.Length; i++)
            {
                values[i] = propertyDescriptorCollection[i].GetValue(iListItem);
            }
            dataTable.Rows.Add(values);
        }
        return dataTable;
    }
