I must find a way to merge multiple rows by the vallue from the first row.
For example the image in the following link (http://s21.postimg.org/7g1figt9j/example.jpg)
Any idea how to do this?
Thanks in advance!
When ever I run a query that exceeds 30 queries the time for the query to run goes from less than a second to over 10 seconds to get data. Example I run a query to return 29 rows, it takes .1 seconds, I run a query to return 31 rows it takes 11.2 seconds. I am running mySQL on Windows 2008 Server Dual Core 2.6Ghz with 3GB of Memory. The machine doesn't run anything else.
While upgrading my database schema I have run into a problem with a ForeignCollectionField (ormlite 4.7) not returning rows. With a clean install of the app, rows can be added and displayed as expected.
I am trying to sort huge load of .CSV files produced by our equipment but got stock with sorting part. Every file consists of 30+ columns and can have infinite number of rows. What I need to implement is how to check for events that happen in multiple columns for several rows concurrently.
