Question

I have the following model

The first step is to select all the ProductionBlock with

var blocks = context.ProductionBlocks;

How can I combine the ProductionLog that has no end time with the ProductionBlock?

I tried to do it using a reverse lookup like

var blocks = context
    .ProductionLogs
    .Include("FK_ProductionLog_ProductionBlock")
    .Where(log => log.EndTime == null).Select(log => log.ProductionBlock)
    .Union(context.ProductionBlocks);

But the blocks don’t contains any ProductionLogs. How can I achieve that?

Answer 1

Let me know if i am off base, but you would want.

 var logs = (
       from pl in context.ProductionLogs.Include("ProductionBlock")
            where pl.EndTime == null
       select pl);

You would then have a list of logs and blocks.

var blocks  = logs.SelectMany(x=>x.ProductionBlock)
