llblgen Pro SELECT TOP (n) equivalent query

问题

Is it possible to perform a select top (n) query in llblgen pro?...not LINQ. If so, how can I achieve that using the SelfServicing?

回答1:

Just use the GelMulti overloads that accepts the maxItemsToReturn parameter:

int itemsToReturn = 10;    
OrderCollection orders = new OrderCollection();
orders.GetMulti(null, itemsToReturn);

This is the generated SQL:

SELECT TOP(@p2) [Northwind].[dbo].[Orders].[CustomerID] AS [CustomerId], ... 
FROM [Northwind].[dbo].[Orders]  
Parameter: @p2 : Int64. Length: 0. Precision: 0. Scale: 0. Direction: Input. Value: 10.
