问题 Why does the Meteor collection cursors foreach loop not work in the code below. If I wrap the loop inside a Template.messages.rendered or Deps.autorun function, it works. I dont understand why.

So my table would de like the following: myTable t1 col2 col3 2 1 3 4 (1+3) 4 8 (4+4) 5 13 (5+8) 6 19 (6+13) I'm missing the logic here, short-sightedness perhaps. I was trying it with a cursor as follows: DECLARE @var3 FLOAT DECLARE cursor3 CURSOR FOR SELECT col2, col3 FROM table1

问题 I have a memory problem that I can't figure out. I have one class that does all my database retrieving work. The error I have is the following: android.database.CursorWindowAllocationException: Cursor window allocation of 2048 kb failed. # Open Cursors=733 (# cursors opened by this proc=733) The memory allocation error occurs when I do this: mDatabaseInterface.getGraphForLevel(level); I know it's a leak because I call this method every 2.5 seconds roughly, and the 5 or 6 first calls go
